2. INTRODUCTION

Congratulations on purchasing the GP2-QPA-01 4-channel Preamp by
Gp2 Inc.

The GP2 Pre-amp is designed with the knowledgeable user in mind.
It picks up where the standard pre-amp leaves off.
Basically, hiss free and harmonic distortion almost too low to measure.
The sound is very robust and holds up under wild equalization.
No mid range fog or harshness, as with other pre-amps.
The entire mid-range is well defined and allows for a whole new
experience in the studio.
The top end is smooth with ‘air’ but no roughness
Extends easily beyond hearing range. (No bumping at around 8k or lack
of air)
Headroom is exceptional
Almost impossible to get distortion.

For the user who doesn’t want the classic English ‘processed’ sound or
the American ‘harshness’

.
