AC Adaptor (PSA series; sold separately)

Electric Guitar

English

Graphic equalizer Control 7 octave bands from 100 Hz to 6.4 kHz by 15 dB up or down.

The Graphic Equalizer GE-7 adjusts the harmonic contents of an instrument or microphone in seven separate bands. It covers the frequency spectrum for electric bass, electric guitar, keyboard, mic, etc., to adjust them for room acoustic or to accent a particular tone range. Each control adjusts a slightly expanded octave to yield 15 dB of cut or boost. The first three bands adjust the fundamental and the higher four bans adjust the strength of the harmonic accent. In addition level control is very useful for the balance effect sound.

OUTPUT jack This jack feeds signal to amplifier.

Guitar Amplifier

DC IN jack Accepts connection of an AC Adaptor (PSA series; sold separately). By using an AC Adaptor, you can play without being concerned about how much battery power you have left.

* We recommend that you keep batteries installed in the unit even though youll be powering it with the AC adaptor. That way, youll be able to continue a performance even if the cord of the AC adaptor gets accidentally disconnected from the unit.

* Use only the specified AC adaptor (PSA-series). * If the AC adaptor is connected while power is on, the power supply is

drawn from the AC adaptor.

Indicator This indicator shows whether an effect is ON/OFF, and doubles as the Battery Check indicator. The indicator lights when an effect is ON.

* If this indicator goes dim or no longer lights while an effect is ON, the battery is near exhaustion and should be replaced immediately.

* The CHECK indicator shows whether the effect is on or off, and indicates the different functions. It does not indicate whether the power to the device is on or not.

Pedal Switch This switch turns the effects ON/OFF.

Thumbscrew When this screw is loosened, the pedal will open, allowing you to change the battery.

* For instructions on changing the battery, refer to Changing the Battery.
