The rack is a very versatile unit. Please take the necessary time to look over this manual and

become familiar with the basic layout of controls as well as the unique features. Take time and

let your ears guide you through the tonal possibilities. The EQ sections have been carefully op-

timized for current and classic playing styles and have an extremely wide range of control. It is

possible that you may be just a "tweak" away from your desired sound, so be patient and jot

down the settings that you prefer most. Also become fully aware of the several mode combina-

tions possible with the two channels plus the channel stacking feature.

APPLICATIONS OVERVIEW

cations. The wide input range of channel 2 allows it to remain clean even with high transient

inputs. The stereo effects loop and adjustable send and receive levels aid greatly in achieving

proper signal level and signal to, noise ratio regardless of the effect used. This unit can be

used with either basic power amplifiers or combo (instrument level) amplifiers. We strongly rec-

ommend that you audition this preamp with our MosValve power amplifier, as this combination

will Insure optimum tone and performance.
