Used GML 8304 (2000’s era) 4 Channel Microphone Preamp Series 1
George Massenburg Labs built the 8304 to expand upon the 8300 model preamp. This design includes a completely bipolar transistor circuit with direct-coupled; no transformers, FET’s, IC’s, or electrolytic capacitors. These solid state preamps are squeaky clean, and boast an extreme 15db to 70db gain range. You won’t find one this cheap, this clean, and with the power supply anywhere else.
External power supply included.
Balanced XLR inputs (4) and outputs (4)
Switchable phantom power per channel
