UA LA-6176 Signature Channel Strip: Tube Preamp and Compressor Plugin

The 610 preamp section uses the modern 610-B circuit, which Universal Audio says offers deeper EQ controls than the original design. Universal Audio describes its harmonics and overdrive as smooth and rich, and it is intended for vocals and instruments.

The 1176 mode uses the FET-based circuit associated with fast response to guitar, bass and drum transients. The LA-2A mode uses optical compression. Switching between the two modes gives you a fast or a smooth compression character within the same channel strip.

When used with an Apollo interface, the plugin supports Unison, which places the three processors in a single Unison slot for realtime recording. Universal Audio says this lets you record with the impedance and gain stage behavior of the original 610 preamp.

Because the processing runs in realtime during tracking, the sound you hear while recording is the sound that is captured. This makes the plugin suited to recording vocals and instruments through the channel strip rather than adding it only at the mixing stage.
