and DIGITAL EFFECTS ON/OFF, use a double footswitch* with a stereo 1/4” jack.
EFFECTS LOOP - RETURN and SEND Jacks
1/4” jacks allow you to connect an effects processor to the R120DSP. Plug a shielded guitar cable into the
SEND jack of the R120DSP and into the INPUT on the effects processor. Use another shielded guitar
cable from the OUTPUT of the effects processor to the RETURN jack on the R120DSP.
PREAMP OUT - TO EXT POWER AMP
This 1/4” jacks allows you to connect to a seperate powered speaker cabinet or directly into a 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 OUT - TO RECORDING DEVICE
This 1/4” jack allows you to connect to a PA system or recording device. The Speaker Simulator is already
engaged for the best sound. You may also run the signal out to a power amp with volume controls and
from there into a speaker cabinet. This output is ideal for direct connection to a PA system for live
performances....it eliminates the need to use a microphone with the PA. The line output is not controlled by
the master volume control.
GND LIFT Switch
This switch electrically references the chassis to correct the line phase in the instance where the AC wall
outlet may not be properly grounded. Set the switch to the postion that provides the least amount of “hum”.
POWER INLET Module
The Power Inlet module accepts the detachable power cord included with the unit.
CD INPUTS
These two RCA jack inputs allow for a direct connection by a CD player or tape player to the amplifier.
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.
