Two Channel Reflected Plate Amplifier Tube Preamp for Mics and Instruments
The Model 207D is an RPA tube mic and instrument preamp offers extremely low noise and high gain that meets or exceeds the performance of preamps costing many times more. The Model 207D will reveal the subtlety and power of both vintage and modern microphones. With its S/PDIF digital output and Word Clock connection, the Model 207D offers direct digital connection to your signal chain, with up to 96kHz sampling rates.
The MicLim„ microphone limiter, from our flagship Model 1788A Eight Channel Premium Remote Controlled Mic Preamp, makes the Model 207D virtually impervious to input clipping – the perfect front end for digital recorders and DAWs to record hotter tracks at the highest possible resolution.
The Model 207D captures a sound that is warm, full and true to life. Whether you are recording, mixing front of house or broadcasting, give your microphones a great start with the Aphex Model 207D Tube Mic/Instrument Preamp.
