FAQ: SP-1 Standard Pencil Microphones

This article answers frequently asked questions about the UA SP-1 microphones.

Getting Started

What are the SP-1 Pencil Microphones?

The SP-1 Pencil Microphones are a pair of small diaphragm condenser microphones

How do I mount the SP-1?

Each microphone snaps into the included mic stand mount. Mounts may be attached to a microphone stand or the included t-bar for stereo applications. Each mic stand mount includes a pre-installed 5/8" to 3/8" adapter that can be removed for 5/8" mic stands. For 3/8" mic stands, leave the adapter in.

The included stereo bar (t-bar) doesn't fit my mic stand. What do I do?

The included stereo bar (t-bar) includes a pre-installed 5/8" to 3/8" adapter that can be removed for 5/8" mic stands. For 3/8" mic stands, leave the adapter in.

Which direction should SP-1 point?

The SP-1 is an end address microphone, meaning sound enters through the end or top of the microphone.

Which cable should I use for SP-1?

A standard, balanced, 3-pin XLR cable

When should I use the windscreen?

The windscreen should be used when the microphone may be exposed to large amounts of air movement.

Does SP-1 come with any plug-ins or software?

Yes! We designed custom Apollo Channel Strip Presets for Apollo and SP-1 to give you great sounding results right out of the box. Download the UA Connect app and follow the steps to register your SP-1. Once the microphones are registered, you will receive a confirmation email with a link to download the presets, and instructions on where to install them.

How can I import my Channel Strip Presets into Console? 

  1. Unzip the downloaded file.
  2. Move the folder to the following location:

macOS: Macintosh HD/Library/Application Support/Universal Audio/Presets/Channel Strip

Windows: C:\Program Files (x86)\Universal Audio\Powered Plugins\Presets\Channel Strip

Watch the UAD Basics video for more information on how to use your presets.

What is SP-1 great for?

SP-1 is great for acoustic instruments, drum overheads, piano, choir, and field recording applications.

What are the differences between SD-1 and SP-1?

SD-1 is dynamic mic, great for vocals or high SPL sources. SP-1 is a pair of small diaphragm condenser mics that deliver a more detailed sound, especially on quiet sources

General Information

Does the SP-1 need phantom power?

Yes, the SP-1 requires 48 VDC phantom power for operation.

What stereo technique can I achieve with the spacebar?

Any stereo recording technique (spaced pair, XY, ORTF) that utilizes (2) directional microphones may be used.

Which shockmount can I use with the SP-1?

Any adjustable shockmount designed for small diaphragm condenser or shotgun microphones may be used. Universal Audio does not offer a shockmount for SP-1.

Is mid-side recording possible with the SP-1?

No. Mid-side recording requires (1) directional microphone and (1) figure-8 microphone. Since SP-1 is a cardioid microphone, this is not possible.
