GEORGE MASSENBURG LABS 8302 Series II Two-Channel Microphone Preamp

The GML 8302 Series II Dual-Channel Microphone Preamp is a benchmark in audio fidelity, renowned for its unparalleled clarity, precision, and ultra-transparent sound. Part of the celebrated 8300 Series II, this 2-channel preamp is engineered for audio professionals demanding the highest level of sonic accuracy. Leveraging continuous research and cutting-edge components, the 8302 delivers life-like realism and an impressively high resolving power.

This unit features redesigned front-panel controls, including a +48V phantom power switch and a phase reverse option, optimized for convenience and minimal noise. The 8302’s architecture is entirely transformerless, using all-discrete, bipolar transistor circuitry with no FETs, ICs, or electrolytic capacitors in the signal path, ensuring pristine, uncolored sound reproduction. Outputs are direct-coupled with an active servo circuit, eliminating DC offset while preserving tonal accuracy. Gain is adjustable from 10dB to 65dB in precise 5dB steps, while a +24dBv clip indicator alerts users to potential signal overloads.

Housed in a 1U rack-mount chassis, the 8302 is a compact yet powerful addition to any professional setup and can be upgraded to a 4-channel model if needed. Each unit includes an external GML Model 8355 power supply and a 5-pin XLR power cable for reliable operation.
