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?

What is SP-1 great for?

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.
