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.
MASTER - Volume Control
The MASTER volume control adjusts the overall sound level.
REVERB control
Adjusts the amount of reverb added to your guitar’s signal. Turn the knob clockwise to increase the
effect.
CHORUS button and ON/RATE LED
Push in to activate the CHORUS. The ON/RATE LED is illuminated when CHORUS is ON and
flashes to indicate RATE speed.
DEPTH control
Controls the modulation depth for the CHORUS effect. Lower DEPTH settings (counterclockwise)
produce a more subtle detune effect, while higher settings produce a more extreme detuning effect.
TREBLE/MID/BASS controls
Tone controls or EQ. The BASS control boosts or cuts the amount of low frequency, or bass sound.
Treble does the same for high frequencies, MID adjusts the midband frequencies.

RATE control
This controls the delay time for the CHORUS effect. Lower RATE settings result in slower sweep
speeds. Higher settings result in faster speeds. The ON/RATE LED flashes to indicate the rate of the
speed of the sweep.

PHONE (HEADPHONE) jack
Plugging your headphones into this jack disconnects the sound going to the speakers and allows you
to practice in private.
CHROMATIC TUNER section
This built-in Chromatic tuner allows you to tune your guitar without unplugging from your amplifier.
Please see “Built-in Chromatic Tuner Functions” for a more detailed description on how to operate
the tuner.
POWER switch & LED
Turns the amp ON and OFF. When the LED is lit, the amp is on.
CHORUS FTSW (Footswitch) Jack
Remote control CHORUS ON/OFF with a single footswitch* connected to the input with a 1/4 jack
cable.
REV/CH FTSW (Footswitch) Jack
To control CHANNEL selection, plug a single footswitch* into this jack. To control REVERB ON/
OFF and CHANNEL selection, us a double footswitch* with a stereo 1/4” jack.
EFFECTS RETURN / SEND Jack
1/4” jacks allow you to connect to an effects processor. Plug a shielded guitar cable into the SEND
jack of the RT122C into the INPUT of the “loop” section on the effects processor. Use another
shielded guitar cable from the OUTPUT of the “loop” section of the effects processor to the RE-
TURN jack on the RT122C.
PREAMP OUTPUTS - LEFT/RIGHT
1/4” jacks allow you to connect two seperate powered speaker cabinets or directly into a stereo
power amp - like the Rocktron Velocity 100 and from the power amp into two 4x12s, a stereo 4x12
or a stereo 2x12 cabinet. The preamp output is controlled by the master volume control.
LINE OUTPUTS - LEFT/RIGHT
The 1/4” jacks allow you to connect to a speaker simulator and into a PA system or recording de-
vice. You may also run the signal out to a stereo power amp with volume controls and from there
into two 4x12s, a stereo 4x12 or a stereo 2x12 cabinet. The line output is not controlled by the
master volume control.
* Rocktron Rampage single (RFS1) and double (RFS2) footswitches are available and sold
separately.

Built-in Chromatic Tuner Functions
On/Off button
Press this button to engage the tuner function. When tuner is on the LED lights will be on depending
on the note you play.
A.CALIB. button
A.Calib =Auto Calibration. To match the pitch of any instrument or audio source (like an old piano
or tape player) press the auto calibration button while playing the note on the instrument. (Note: you
might have to first tune one string on the guitar by ear to match the actual note if the piano is out of
standard tuning or if tape player you are playing along with runs slower or faster than normal). Once
you have one note on the guitar tuned to the source - simply play that note on the guitar - while the
note is “ringing” press the Auto Calibration button. The tuning pitch of the tuner will automatically
be shifted the match the pitch of the audio source. Release the button and tune the remaining strings
as normal with the tuner. The tuner at this point has automatically adjusted the tuning range to match
that pitch. To reset the tuner to standard 440Hz pitch you turn the tuner off and then back on again.
NOTE LED display:
These LEDs show the note being tuned. The LED under the note being tuned will be lit.
TUNE LED display
This series of 5 LEDs shows you if the note being played (tuned) is either sharp or flat.
To Tune:
1) Turn on tuner function
2) Play a note on your guitar. The tuner automatically senses the note being played and will show
you the note which is the closest to the one being played by lighting the appropriate LED in the
NOTE LED display.

CDEFGAB#
If the LED(s) to the right of the center green LED are lit, then the note is sharp. Tune the string
down until the center green LED is lit - the note should then be “in tune”.
3) The “TUNE LED display shows by “how much” the guitar is out of tune from the note being
played (in standard 440Hz tuning) indicated in the NOTE LED display. If the LED is to the left of
the Center green LED the note is flat. Tune the string up until the LED reaches the Center green
LED. Once this LED is reached the note is in tune.

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.
