The 3124+ is designed with the professional engineer in mind, giving the highest possible quality 4 channel mic preamp, while keeping the size and price at a reasonable level. Equally at home in the control room, the studio, and news or recording truck, at the house console, on the stage, direct-to-DAT, or at the artist's disposal for the source of his music.
The model 3124+ utilizes the same microphone preamp circuit that is used in all API consoles. It uses the RE-115 K mic input transformer and the same output transformer that is used in all API equalizers. All four mic inputs of the 3124+ are powered by an internal 48 volt phantom power supply, front panel switchable for each channel. Also provided is a front panel 20 dB 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.
