The 32Cpre+ delivers +20 to +70 dB of smooth gain capable of driving a wide range of mic types, including ribbon. In addition to 180 ° Phase, 48V, -20 pad, and HiZ impedance switches, the front panel features combo XLR with a ¼” jack connector that lets you plug a microphone or instrument into the 32Cpre+ directly without having to access the rear panel of the 500 Series rack.
