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 rst three bands adjust the fundamental and the higher four bans adjust the strength of the harmonic accent.

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 you’ll be powering it

with the AC adaptor. That way, you’ll be able to continue a performance even if the cord of the

AC adaptor gets accidentally disconnected from the unit.

* Use only the specied 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 eect is ON/OFF, and doubles as the Battery Check indicator.

The indicator lights when an eect is ON.

* If this indicator goes dim or no longer lights while an eect is ON, the battery is near

exhaustion and should be replaced immediately.

* The CHECK indicator shows whether the eect is on or o, and indicates the dierent

functions. It does not indicate whether the power to the device is on or not.

Pedal Switch

This switch turns the eects 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.”

down the volume, and turn o all the units before making any

* Once the connections have been completed, turn on power

to your various devices in the order specied. By turning on

devices in the wrong order, you risk causing malfunction and/

or damage to speakers and other devices.

When powering up: Turn on the power to your guitar amp last.

When powering down: Turn o the power to your guitar amp rst.

* Before turning the unit on/o, always be sure to turn the

volume down. Even with the volume turned down, you might

hear some sound when switching the unit on/o. However,

this is normal and does not indicate a malfunction.

Use of Battery

* A battery was installed in the unit before it left the factory. The

life of this battery may be limited, however, since its primary

purpose was to enable testing.

* If you handle batteries improperly, you risk explosion and uid

leakage. Make sure that you carefully observe all of the items

related to batteries that are listed in “USING THE UNIT SAFELY”

and “IMPORTANT NOTES” (supplied on a separate sheet).

* When operating on battery power only, the unit’s indicator will

become dim when battery power gets too low. Replace the

battery as soon as possible.

* Batteries should always be installed or replaced before

connecting any other devices. This way, you can prevent

malfunction and damage.

Changing the Battery

1. Hold down the

pedal and loosen

the thumbscrew,

then open the

pedal upward.

* The pedal can be

opened without

detaching the

thumbscrew

completely.

2. Remove the old

battery from the

battery housing,

and remove the snap cord connected to it.

3. Connect the snap cord to the new battery, and place

the battery inside the battery housing.

* Be sure to carefully observe the battery’s polarity (+ versus -).

4. Slip the coil spring onto the spring base on the back of

the pedal, and then close the pedal.
