API 3124V 4-Channel Mic Preamp

The API 3124V is a four-channel mic preamp with four front-panel instrument DIs and output level control on each channel. The first iteration of the API 3124 became one of the most popular API preamps designed by former API owner, Paul Wolf. A 4-channel preamp with punch and clarity, the 3124 was an instant hit on snare and toms. However, it's hot output could easily overpower A to D converters, which meant that some kind of output attenuation was required, since using pads changed the sound. Rather than have its users depend on 3rd-party level attenuation, API released the 3124V, the same 4-channel preamp circuits with the addition of a true API-designed variable output level control. The output level enables you to use the 3124V on high-SPL sources, crank the input for more transformer saturation, and control the output to your converters. Best of all, you have API sound from mic to converters.  API 3124V - Just the Facts: Classic API Circuit Design Uses API 2520 Op Amps Variable Ou
