The Harrison 32Cpre+ 500 Series Module is a transformer-coupled microphone preamp based on the Jensen JT-MB-CPCA design from the 32Classic console. It provides +20 to +70 dB of gain for a wide range of microphone types, including ribbon, dynamic, and condenser mics. The module features a front-mounted combo XLR/¼” input, 48V phantom power, polarity reverse, and HiZ impedance switches for flexible recording and instrument connection. High-pass and low-pass filters allow precise frequency shaping, while the input overload LED provides visual feedback to manage gain. Compatible with 500 Series racks, the 32Cpre+ integrates into modular studio setups for tracking, mixing, and monitoring workflows.

Features the JT-MB-CPCA transformer from the 32Classic console, delivering tonal response with full low-end, open midrange, and smooth highs. Designed for recording vocals, instruments, and line-level sources, it reproduces the classic Harrison character in a compact 500 Series module for flexible studio workflows.
Provides +20 to +70 dB of gain and supports ribbon, dynamic, and condenser microphones. This range allows engineers to drive a variety of mic types effectively, enabling consistent tracking of vocals, instruments, or line-level signals while maintaining tonal clarity across different sources.
Offers convenient front-panel access for microphones and instruments, paired with 48V phantom power, polarity reverse, and HiZ impedance switches. This setup allows quick connection and flexible routing in the studio, supporting condenser mics, direct instrument input, and phase correction during recording sessions.
High-pass filter ranges from 25 Hz to 3.1 kHz with a 3 dB resonant peak, and low-pass filter ranges from 160 Hz to 20 kHz with a 12 dB/octave slope. These filters provide precise frequency control, helping engineers reduce unwanted low or high frequencies, shape tone, and optimize tracks for mixing or summing.
Designed for integration into 500 Series racks, the 32Cpre+ supports modular studio configurations. The input overload LED provides visual feedback to prevent clipping, while the compact format enables flexible routing, portable setups, and combination with other 500 Series modules for professional recording and monitoring workflows.
