Aphex 207D
Two Channel Tube Preamp

207D

The Model 207 is an audiophile quality tube mic preamp without the high cost usually associated with such products. It will meet or exceed the performance or preamps costing many times more. The Model 207 will reveal the subtlety and power of vintage condensers, ribbons, electrets, and popular dynamic mics. Even the world's most respected microphone will sound better.

The instrument inputs also are quieter and have more gain, than conventional instrument preamps. The MicLim circuitry, previously only available in our flagship Model 1100 2 channel and Model 1788 8 channel mic preamps, makes the Model 207 virtually crashproof - making it a perfect front end for digital recorders.

By combining the best traits of tube and solid state circuitry, the Model 207 captures a sound that is warmer, fuller and more true to life. Whether you are recording, mixing live, broadcasting or webcasting, the signal has to travel a long journey before its final delivery. So give your sound a great start with the Aphex Model 207 Tube Mic/Instrument Preamp.
