STEREO HEADPHONES JACK STEREO HEADPHONES JACK
By inserting a set of stereo headphones into this jack you will be able to monitor your sound or
practice without disturbing your neighbors. The headphone volume level is adjusted by the Master Volume.
We suggest you begin with the Master Volume full off (counter-clockwise), then slowly bring up the
volume to the desired level. If you hear some distortion in your headphones that is not present with the
speakers on, turn down the volume as you are probably overdriving your heaphones and could ruin them.
Any impedance headphones will work. However, optimum impedance is 75 ohms.
WARNING: DO NOT USE MONO HEADPHONES. USE STEREO HEADPHONES ONLY! WARNING:

condition, turn the Speaker Switch to the "Stand By" position before turning the unit on or off.

REAR PANEL FEATURES

REAR PANEL FEATURES
EFFECTS LOOP EFFECTS LOOP
The Effects Loop is located POST EQ and PRE Master Volume in the signal path. The level appearing at the
Send jack is controlled by the Gain control on the front panel. If you are getting too hot a signal to the
input of your effect, reduce the level of the Gain control and raise the level of your Master Volume control
to retain similar overall volume levels. By using the Gain, Master Volume and Effects Blend controls,
optimum performance should be easily obtainable with any effects device.
The Effects Loop is designed as a "sidechain" (parallel) function similar to those found on mixing
consoles. Use of the Effects Loop should greatly reduce noise generated by effects devices (as
compared to in-line effects loops). Additional features of this type of loop can be found below under the
Receive jack section.
SEND JACK SEND JACK
Run a shielded patch cable from the Send jack to the input of your effects device. This jack may be used
as an additional line level output, in which case its level is determined by the setting of the Gain control.
RETURN JACK RETURN JACK
Run a shielded patch cable from the output of your effects device to the Return jack.
One unique feature of the Return Jack is the ability to practice along with pre-recorded music. Insert a
sound source into the Return jack (make sure it is a mono source). Use the Effects Blend control to mix
the level of the recorded music with your instrument's level. The combined signal will be heard through your
speakers, headphones, or both. The send jack is not used.
