This Hi-Z input can accept input levels as high as 20 dBu, making it perfect for keyboards and other high level devices. 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. Like the 3124V, the API 3124MV Discrete 4-Channel Mic/Line Pre with Stereo Mixer provides up to 65 dB of gain.
A 1/4″ phone jack is available on the rear panel for each channel as an insert tip-send/ ring-return placed between the mic pre amp output and the mixer input. Also provided is a front panel -20 dB pad switch that affects both the mic and line in. The unit offers Variable Output Level Control, switchable 3:1 output transformer selection, and an internal 48-volt phantom power supply, which is front panel switchable for each channel. It uses the RE-115 K mic input transformer along with the same output transformer that is used in API equalizers. The 3124MV utilizes the same microphone preamp circuit that is used in all API consoles. Both models are equally at home in the control room, studio, and recording truck or on stage. However, the API 3124MV Discrete 4-Channel Mic/Line Pre with Stereo Mixer provides an additional audio mixer with a transformer balanced output, keeping the unit size and price reasonable. Both units give four channels of the highest possible quality mic preamp. API 3124MV Discrete 4-Channel Mic/Line Pre with Stereo Mixerīoth the 3124V and the 3124MV are designed with the professional engineer in mind.
