Understanding UAD Console Features

UAD Console is remote control and monitoring software for your Volt hardware that acts as a virtual mixing board, routing audio between your Volt interface's analog and digital inputs and your recording software (DAW).

Direct Monitoring

Direct monitoring is the primary function of UAD Console. Direct monitoring passes input signals directly to the monitor and headphone outputs, instead of being monitored through the audio software (DAW). Direct monitoring lets you hear your live inputs in real time, without audible latency. Without direct monitoring, inputs are subject to DAW buffering latency.

Why use direct monitoring?

With direct monitoring (also known as hardware monitoring), you hear the input signals directly from the Volt hardware with no latency, bypassing your audio software altogether. Direct monitoring includes all preamp features, including Tone, Max, Vintage, and 76 Comp processing.

When you monitor input signals through your audio software (software monitoring) with Direct off, those signals pass through the software before you hear them from the Volt monitor and headphone outputs. These signals use the software’s I/O buffer, which causes latency, an amount of delay that increases as the buffer size is increased.

Use direct monitoring when you are recording sources that you don’t want to monitor through your software, for example, when recording vocals or instruments without plug-in processing from your DAW, but including Volt preamp processing.

How to prevent doubled audio when direct monitoring:

1. Unmute the input in UAD Console to enable Volt's latency-free direct monitoring.
2. Disable software monitoring in your DAW, or mute the input in the DAW, to prevent signal doubling. Note that LUNA can manage muting/unmuting of inputs automatically.
3. After recording, unmute the track in your DAW

Direct monitoring simplified

• To directly monitor through UAD Console: Unmute an input channel in UAD Console. When an input is unmuted in UAD Console, it is directly monitored, and heard in the UAD Console monitor mix. Mute the same inputs in your DAW to prevent doubled, phased, or thin audio. Use this for the fastest response, with Tone Shaping, Max Compression, Vintage, and/or 76 Comp processing.
• To monitor through your DAW software: Mute the input channel in UAD Console. You do not hear the direct signal in UAD Console, and you hear your input signals through your DAW software.

Direct monitoring notes

• Direct includes the input’s Tone Shaping, Max compression, Vintage, or 76 Comp processing, if enabled.
• When direct monitoring (UAD Console inputs not muted), disable the software monitoring feature in your audio software (or mute record or input-enabled channels in your DAW) to prevent signal doubling, which can make your input sound thin or “phasey.'
• When software monitoring (UAD Console inputs muted), you may notice your inputs have latency (a slight delay) before they are heard, as a result of buffering and signal processing in your DAW.
• If you want to hear your input signals processed through plug-ins loaded in your DAW, mute inputs in your DAW.
• The input signal is always sent to the DAW for recording, regardless of UAD Console mute states.

Other features of UAD Console

• Cues: UAD Console supports two Cues (individual mixes for performers, separate from the main mix)
• Loopback channel: Route computer system audio into UAD Console to incorporate audio from audio apps, videos, games, or other system events into your audio production stream.
• Alt monitors: check your mix on alternate monitors (Volt 4 Max, 4P Max, 876).
• Talkback: Use a built-in Talkback mic to communicate with performers (Max, 876).

Getting Started with Volt in UAD Console

Use these steps to get started with your Volt audio interface and UAD Console software.

Plugging in and setting levels

• Connect an instrument: On Volt Gen 2 and Volt Max models, Hi-Z inputs are enabled automatically when you plug an electric guitar or bass into an instrument input. On Volt 876, press the INST buttons to manually switch to Hi-Z instrument impedance and levels.
• Use 48V Phantom Power: Toggle 48V on for condenser microphones that require phantom power. Phantom power is available only for XLR inputs.
• Set input gain (Gen 2, Max, 876): While playing, turn the gain knob up to boost your microphone or instrument signal before recording. Aim to keep signal meters in the green and yellow in the meter, avoiding the red (clipping). To set gain automatically, click AUTO-GAIN, then play your loudest part for ten seconds, and let UAD Console automatically set your gain to a safe level.
• Set input gain (Volt 1): While playing, turn the gain knob for your input up to boost your microphone or instrument signal before recording. Aim to keep the LED signal indicators in the green, and avoid the red (clipping).
• Apply Tone Shaping (Gen 2, Max): Cycle through classic preamp sounds with the TONE button.
• Apply Max compression presets (Max): Cycle through classic compressor sounds with the MAX button.
• Apply Vintage and 76 Comp processing (876): Toggle vintage tube preamp emulation or built-in 1176-style analog compression with the VINTAGE and 76 COMP buttons.

Listen to direct or DAW software signals

When you mix signals with UAD Console, you can hear your inputs without latency (direct monitoring) or hear your signals through your DAW software (software monitoring).

• To hear inputs without latency, unmute channels with the the mute (M) switches on each channel fader to monitor channels directly in UAD Console.
• To hear inputs through your software, mute channels in UAD Console to monitor through your software (for example, when using software plug-ins).

Mix your signals

• Adjust channel faders and panning: Adjust how loud an input sounds in your monitor mix, and where it sits in the stereo field, with the channel faders and pan knobs.
  Note: Moving the faders doesn't change the signals sent to your DAW for recording. Only the level in your headphones or monitor speakers changes.
• Solo a channel: Toggle the Solo (S) switch to temporarily hear only the current channel. You can solo multiple channels at once.

Make different individual mixes with the Monitor Mix and Cues

• Monitor mix: Listen to the main mix that you hear in the speakers and headphones (if not assigned to Cues).
• Cue mixes: Cues are separate mixes you can send to headphone outputs, or to a specific hardware output. For example, a vocalist can get more of their own voice in their headphones,without changing what you hear in the main mix.

UAD Console for Volt Controls

  Note: The maximum duration is 90 seconds.
• Apply Gain options:
  • WHILE LISTENING applies gain changes every two seconds for the Auto-Gain duration. You can only use WHILE LISTENING with one or two preamps enabled for Auto-Gain.
  • AFTER LISTENING applies the gain change after the Auto-Gain listening duration is complete.
• Listening Threshold: Determines the lowest level at which Auto-Gain detects a signal and begins adjusting gain. The default setting is -50 dBFS, which may be too quiet for low-level sources. To set a different threshold, drag up or down in the box, or click in the box and type a new value, then press Enter.
• Peak Target: Determines the maximum peak level that Auto-Gain should set for your material. The default setting is -8 dBFS. To set a different peak target, drag up or down in the box, or click in the box and type a new value, then press Enter. Be aware that higher settings (less headroom) increase the risk of digital clipping.

48V phantom power

If you are using equipment that requires XLR phantom power, such as a condenser microphone, engage the 48V switch on the channel. When 48V phantom power is enabled, the 48V LED is lit red in UAD Console and on the Volt hardware. The 48V LED/indicator blinks briefly when enabling or disabling phantom power.

Caution:

• Activate 48V only with compatible equipment such as phantom powered microphones. Incompatible equipment could be damaged by the applied voltage.
• Do not connect or disconnect equipment from the input when 48V phantom power is enabled, or when the LED is blinking.

Polarity (Volt 876)

To invert the channel's signal polarity toggle the polarity switch. When enabled, the switch is lit in UAD Console and on the Volt 876 hardware for the selected channel.

Tip: Invert polarity to reduce phase cancellations when more than one microphone is used to record a single source.

Alt monitoring

On \Volt 4 Max, Volt 4P Max, and Volt 876 you can monitor the stereo mix on a secondary pair of speakers. You can enable the feature in UAD Console Settings, or from your Volt hardware.

Alt monitor outputs

When Alt monitoring is active, you hear the main mix on analog outputs 3–4. Connect your alternate speakers to those outputs for Alt monitoring.

Important: To prevent ALT from accidentally overriding existing Line Out 3-4 assignments, you must first enable the ALT function before the feature can be used. If the ALT button is unlit, the function is not yet enabled.

When Alt monitoring is active, any signals that were previously heard on outputs 3–4 are no longer heard on those outputs. For example, if a Cue mix is mirrored to outputs 3–4, that routing is removed. When Alt monitoring is disabled, signals previously heard on outputs 3–4 must be manually restored.

To enable Alt monitoring in UAD Console:

1. Click Settings in the Monitor column on the right side of the UAD Console window, or choose UAD Console > Settings from the UAD Console menus.
2. Set Alt Monitoring to On.
3. To disable Alt monitoring, set Alt Monitoring to Off.

Monitor / Alt switches

The Monitor and Alt switches send the mix to either the Monitor outputs or the Alt outputs. These switches are only available when Alt monitors are enabled in UAD Console Settings.

Mono

This switch sums the left and right channels of the stereo monitor mix into a monophonic signal. The mix is mono when the button is lit.

Mute

This switch mutes the monitor outputs. The monitor outputs are muted when the switch is lit. Headphone outputs are not muted. The Volt hardware mute indicator (except Volt 1) mirrors this setting.

Session Files

You can manage your Volt UAD Console configurations with session files. A session file saves your current UAD Console settings to disk. You can load a session file to restore UAD Console to a previously saved state.

Note: Monitor settings and hardware settings are global parameters that are not saved in session files.

The specific settings saved in Volt UAD Console session files are listed below:

Saved in Volt session file

• Analog preamp values (Tone, Max, Vintage, 76 Comp, Inst switch, Gain, 48V, Polarity)
• All knob, mute/solo, and fader values (pans, cues, levels)
• Channel mute state
• Input stereo link state
• Loopback channel level

Not saved in Volt session file

• Input names
• Monitor level
• Clock source
• Sample rate
• Cue output settings

Session File Location

By default, session files are stored in:

• Mac: Users/[UserName]/Documents/Universal Audio/Volt Sessions/
• Windows: C:\Users\[UserName]\AppData\Roaming\Universal Audio\Volt Sessions

Session files can be stored anywhere on disk, but using the default location is recommended, because UAD Console always uses this location for the Session Browser and Open/Save dialogs presented by the computer's operating system.

Note: Session files must reside in the default location to appear in the Session Browser within UAD Console.

Session Files Suffix

Volt session files have the ".volt[model]" suffix (for example, Volt 876 session files are named [session].volt876, and Volt 4 session files are named [session].volt4). The suffix is added to session files automatically when saving to disk; however, the suffix is not displayed in the file save dialog (the suffix should not be manually typed when saving a session file).

To save and load sessions

• Click the session name at the bottom of the Monitor Column to open the Session Browser at the left of the UAD Console window.
• To load a session, click the session name.
  Note: To prevent potential external equipment damage, a warning appears if the session you are loading requires +48V phantom power to be enabled on one or more inputs. To load the session and enable +48V phantom power, you must click OK. Otherwise, click Cancel.
• To save the current session, click Save, type the name (or leave it as is), and click Save.
• To rename a selected session, click Rename, type the new name and click Rename.
• To delete a selected session, click Delete, then click Delete again.

The Session Browser

Control Room

The Control Room column can be accessed by clicking the CTRL ROOM button in the Show section of the Monitor column. The Control Room settings let you activate the Talkback mic and adjust talkback levels to the Cues, and select the source that is heard at the monitor 1–2 outputs.

1. Talkback controls (Max, Volt 876): These knobs control the talkback mic levels heard in the monitor mix and Cues 1 & 2. The mute switches prevent the talkback mic from being heard in the mix or cues.
2. Dim / Talk (Max, Volt 876): Activates the talkback mic and the Dim function. Talkback is active when the button is lit, and the monitor level is reduced to prevent feedback.
3. Source: Selects which mix bus is heard at the monitor outputs. You can choose Monitor, Cue 1, or Cue 2.

Talkback

Talkback is typically used to communicate with performers. Talkback is activated using the dedicated hardware TALK or DIM/TALK button on the Volt hardware, or the DIM / TALK button within the UAD Console Control Room strip.

Dim / Talk switch

• Continuous (latched) talkback – Press the switch once to latch or unlatch talkback. When latched (lit), the talkback mic signal is sent to the monitors and cues.
• Momentary (unlatched) talkback – Press and hold for momentary talkback. The talkback mic sends signal while the button is held and stops sending signal when the button is released.

Dimming

When talkback is active, monitor output is lowered (dimmed) by 20 dB to allow the talkback mic to better capture the voice input instead of program material from the monitor speakers.

Talkback Levels

When talkback is active (the button is latched or held), the talkback mic signal is sent to the main mix and the two Cues. You can control the level of talkback signal to the mix and each Cue with the knobs on the Control Room strip, and mute the talkback signal to the mix or Cue by pressing the mute switch.

Source

Enable a Source button to select which mix is heard at the monitor or Alt outputs. You can choose Monitor, Cue 1, or Cue 2.

• To hear the main mix, choose Monitor.
• To hear a Cue mix, choose Cue 1 or Cue 2.

Note: If a Cue is set to Mix in the Cue Outputs window, you cannot set the monitor source to that Cue, because the main mix is the default setting. A dialog with instructions appears if you try to monitor a Cue that is set to Mix.

Cues

You can use cues to create mixes that are different from the monitor mix (the main mix). Cues are typically used for performers that want to hear a custom mix in headphones.

On models that have additional outputs (Volt 4, Volt 4 Max, Volt 4P Max, Volt 876), cue mixes or the monitor mix can also be optionally mirrored (heard) through an available output pair.

How do I hear Cues?

Cues are assigned in the Cue Outputs window, where you assign Cue mixes or the monitor mix to headphones.

By default, you hear the monitor mix in the headphones. To hear the cue mixes in the headphones, disable the MIX button (unlit) in the Cue Outputs window.

• Open the Cue Outputs window: Click CUES in the Monitor column to open the Cue outputs window.

• Observe the blue box: The blue box always indicates what is heard in your headphones.
  • If the blue box says Monitor Mix to HP, you are hearing the monitor mix in that headphone output. This is the default setting.
  • If the blue box says Cue to HP, you are hearing the Cue mix in that headphone output.
    
     
• Switch between a Cue mix and the monitor mix
  • To hear Cue 1 or Cue 2 in headphones: In a Cue column (Cue 1 or Cue 2), toggle the MIX button so it is unlit. The blue box shows the cue mix is heard in the headphones.
  • To hear the monitor mix in headphones: Toggle the MIX button so it is lit. The blue box shows the monitor mix is heard in the headphones.
• Switch headphones between Cues: You can switch the headphone output (blue HP box) from one Cue to the other, by clicking the blank column space under the Cue row.
  
   
• Mirror a Cue or the main mix to a different output: Mirroring sends the same mix (monitor or cue, depending on lit/unlit switch) to an additional pair of outputs. For example, you could mirror a cue to send the mix to other gear.
  
  Mirroring is available on models that have additional outputs (Volt 4, Volt 4 Max, Volt 4P Max, Volt 876).
  • To mirror Cue 1 or Cue 2 to a different output pair: In a Cue column, select the output pair from the Mirror To menu. The Cue is mirrored when the MIX button is unlit.

• To mirror the monitor mix to a different output pair: In a Cue column, select the output pair from the Mirror To menu. The monitor mix is mirrored when the MIX button is lit.

Note: In an expanded system on Volt 876, mirroring to an ADAT output pair effectively sends the cue mix to the expander unit's corresponding analog outputs. For example, routing to ADAT 3-4 on an 876 expanded system sends audio to analog outputs 3–4 on the first expander unit.

Cue adjustments

The cue mixes are adjusted using the two cue sends on each input strip and the Loopback strip. All cue sends are pre-fader and pre-mute so they are not affected by adjustments to the main monitor mix. Cue sends do include Tone/Max/Vintage/76 Comp processing on preamp inputs.

Cue examples

The following examples illustrate different ways you can send Cue mixes to headphones and other outputs with your Volt.

Hear Cue 1 in headphones

The following example shows how Cue 1 can be heard in headphones.

1. Cue mix 1 is heard in the headphones (MIX button unlit, Cue 1 to HP 1 in blue box).
2. Cue 2 is not heard because no output is assigned.

Hear Cue 1 in headphones, main mix to Line 3-4

The following example shows how Cue 1 can be heard in headphones, and the monitor mix is sent to Line 3-4. This example requires a Volt 4, Volt 4 Max, Volt 4P Max, or Volt 876.

1. Cue mix 1 is heard in the headphones (MIX button unlit, Cue 1 to HP 1 in blue box).
2. The monitor mix is sent to Line 3-4 (MIX button lit, Mirror To Line 3-4 selected).

Hear main mix in headphones, Cue 2 to Line 3-4

The following example shows how the monitor mix can be heard in headphones, and the Cue 2 mix is sent to Line out 3-4. This example requires a Volt 4, Volt 4 Max, Volt 4P Max, or Volt 876.

1. The monitor mix is heard in the headphones (MIX button lit, Monitor Mix to HP 1 in blue box).
2. The Cue 2 mix is sent to Line 3-4 (MIX button unlit, Mirror To Line 3-4 selected).

Volt 876: Hear monitor mix and Cue 2 mix in headphones, and mirror Cue 2 to Line 3-4

The following example shows how the monitor mix and the Cue 2 mix can be heard in separate headphone outputs on Volt 876, with Cue 2 mirrored to Line 5-6 outputs.

1. The monitor mix is heard in headphone output 1 (Cue 1 column MIX button lit, Monitor Mix to HP 1 in blue box).
2. The Cue 2 mix is heard in headphone output 2 (Cue 2 column MIX button unlit, Cue 2 to HP 2 in blue box). The Cue 2 mix is also sent to Line 5-6 (Mirror To Line 5-6 selected).

Note: To switch modes using the Volt 876 hardware front panel, a specific procedure is required. See the Volt 876 Hardware Manual.

Active MIDI ports

On any Volt 876 that is connected via USB, the MIDI ports remain active. This includes both USB and ADAT modes, in any configuration.

Note: On macOS, Volt 876 appears as two different MIDI devices depending on whether the unit is in USB mode or ADAT mode. When configuring the device in Audio MIDI Setup, make sure to use the Volt 876 device that is currently active. To distinguish between the devices in Audio MIDI Setup, you can double-click each Volt 876 MIDI device and give it a unique name.

USB mode

In USB mode (the default setting), your Volt 876 is the main interface that routes all audio to and from your computer. USB mode is also the mode for the control unit in an ADAT expansion system.

ADAT mode

ADAT mode has two possible states:

1. ADAT standalone mode
2. ADAT expansion mode

ADAT standalone mode

ADAT standalone mode is the default mode when you switch a Volt 876 unit to ADAT mode. In this mode:

• Volt 876 functions as a standalone mic preamp and A/D - D/A converter
• Analog inputs 1-8 are routed directly to corresponding ADAT outputs 1-8
• ADAT inputs 1-8 are routed directly to corresponding analog outputs 1-8
• Audio from the interface is not routed to the computer
• Volt 876 does not appear as a Core Audio or ASIO device
• Loopback, Control Room, and Monitor controls are unavailable

ADAT standalone mode with computer control

In ADAT standalone mode, when Volt 876 is connected to your computer via USB, the following settings can be controlled within UAD Console:

• Preamp settings
• Sample rate
• Clock source
• USB or ADAT mode

Volt 876 in ADAT standalone mode in UAD Console

ADAT expansion mode

In ADAT mode you can configure the Volt 876 as an expander unit. In this mode, the following Volt hardware can be combined:

• One Volt 4 or Volt Max and one Volt 876can be combined to provide control within UAD Console of up to 12 preamp inputs.
• Two or three Volt 876 units can be combined to provide control within UAD Console of up to 24 preamp inputs. See ADAT expansion with multiple Volt 876 interfaces for more information.

ADAT Expansion with Multiple Volt Interfaces

You can expand your Volt system to include two or three Volt interfaces, for control in UAD Console of 10–24 preamp inputs (at 44.1 kHz and 48 kHz).

Note: You can combine one Volt 4 or one Volt Max with one Volt 876. Volt 4 and Volt Max models cannot be combined.

The following expansion modes are available at 44.1 kHz and 48 kHz:

• Volt 2 Max + Volt 876 expander: 10 preamps
• Volt 4 Gen 2 + Volt 876 expander: 10 preamps & two line inputs
• Volt 4 Max + Volt 876 expander: 10 preamps & two line inputs with gain
• Volt 4P Max + Volt 876 expander: 12 preamps
• Volt 876 + Volt 876 expander: 16 preamps
• Volt 876 + two Volt 876 expanders: 24 preamps

Expanding with multiple Volt 876 units

For Volt 876 expansion, one Volt 876 is set in USB mode as the interface unit, and one or two other Volt 876 units are connected and set in ADAT mode as expander units. Each Volt 876 must be connected separately to the host computer via USB. You can then control all analog preamp settings for the ADAT expander units within UAD Console, and all audio from the expander units is available in the UAD console monitor and cue mixes.

Expanding with Volt Gen 2 or Max and one Volt 876 units

For Volt Gen 2 or Volt Max expansion, one Volt 876 is connected and set to ADAT mode as the expander device.

Both Volts must be connected to the host computer via USB (the Volt 876 can be connected to the HUB port on the Volt 4 or Max). You can then control all analog preamp settings for the ADAT expander unit within UAD Console, and all audio from the expander unit is available in the UAD console monitor and cue mixes.

Important ADAT expansion notes

• To prevent feedback, before you switch a device between USB mode and ADAT mode, make sure all microphones are muted.
• ADAT expansion requires two or more Volt units connected to your computer* via USB, and to each other via TOSLINK optical cables.
• ADAT expansion mode requires the UAD Console app — it cannot be configured using Volt hardware buttons.
• When using more than one Volt 876, configure only one 876 unit to be in USB mode. (Volt Gen 2 and Max do not have a Mode setting, and are always the USB I/O units.)
• When expanding a Volt 4 or Volt Max model, the Volt 4 or Max and Volt 876 must be connected via USB to the computer* and to each other (Volt 876 Optical Out 1 - Volt 4 or Max Optical In).
• Due to S/MUX format constraints, available preamp channels are reduced at sample rates higher than 48 kHz.

*Tip: With a Volt Gen 2 or Max, the Volt 876 unit can be connected to the Volt 4 or Volt Max device's Hub USB port.
