API 3124M+

The model 3124+ utilizes the same microphone preamp circuit that is used in all API consoles. It uses the RE-115K mic input transformer and the same output transformer that is used in all API equalizers. All four mic inputs of the 3124m+ are powered by an internal 48 volt phantom power supply, front panel switchable for each channel. Also provided is a front panel 20dB pad switch that effects both the Mic and Line in.

The model 3124+ can provide up to 65 dB of gain to an output clip level of +30 dBm. The Hi-Z front panel input goes directly to the op amp, allowing a low level input such as a guitar or bass to be amplified without a matching transformer or direct box. This Hi-Z input can take input levels as high as +22, making it perfect for keyboards and other high level devices. The rear output is an XLR connector.

The Model 3124m+ is a 3124+ with the addition of a complete stereo mixer. In conjunction with the gain control of the 3124+, the 3124m+ adds a stereo panner with a level control, and a post fader aux send. The stereo panners and the aux sends are bussed to master output controls and then to the rear panel jacks. A stereo aux return is provided to return effects or cascade additional mixers for more inputs. The unique aux return pot acts like a panner to balance the left/right signal, yet staying stereo. It can also be used as a mono return.
