Owner’s Manual
Firstly, let us congratulate you on your purchase of the DRS-1R/500
Microphone Pre-Amplifier designed for the API 500 series Lunchbox or
suitable compatible rack.
We know you will be as pleased with it’s sonic qualities as we are.
You are now the proud owner of a mic-pre/DI that has the advantages of
more than 40 years experience in audio engineering, today’s component
and manufacturing technology, but still retaining “that sound” uniquely
achievable through Class A design.
As you can tell, Phoenix Audio is dedicated to the development of Class
A discrete echnology used within high build-quality equipment.
The DRS-1 Mic-Pre/DI uses our well proven and loved Class A output
stage (DSOP2), but also has our latest breakthrough in transformer-less
Class A, Discrete Mic Input Technology which gives a "valve-like"
sound. It also incorporates our high input impedance DI circuitry.
You CAN hear the difference!!!
