Precautions

INPUT JACKS - LOW AND HIGH
Connect the output of your guitar to one of the 1/4”input jacks with a shielded guitar cable. Select
LOW for normal, or HIGH for extra gain. Plugging into the LOW input will attenuate your guitar’s
signal cooling down a “hot” guitar. These two jacks provide slightly different input levels. Experi-
ment with these and adjust to your tastes.
PREAMP GAIN - DRIVE
Turning this knob clockwise determines the amount of gain (or distortion) added to the signal.
PREAMP GAIN - CLEAN
This knob controls the Clean Channel Level.
CH SELECT - Button & DRIVE LED
Channel Select button - allows you to select between the DRIVE channel or the CLEAN channel.
The DRIVE LED is ON (or lit) when the DRIVE channel is active.

separately.
CD INPUTS
These two RCA jack inputs allow for a direct connection by a CD player or Tape player to the ampli-
fier. You can then jam along with CDs or tapes to rehearse songs, learn new songs or just for fun!
Warning!!! When using Headphones with the CD inputs - make sure you turn down the
Levels on both channels BEFORE unplugging headphones - otherwise excessive CD volume
will be produced.

AGX (Automatic Gain Expander)
Rocktron’s patented AGX system solves the long standing problem encountered by guitar players
when using high gain distortion. The AGX circuit expands the gain of the amplification circuit only
when required based on the input level. When no signal is present, the AGX circuit expands down
the amplification level to a point where hum and noise are dramatically reduced.
