Precautions

Power requirements

Power

requirements

for electrical

equipment

differ

from area

to area.

The operating

voltage of

this machine

is

preset

at the

factory

according

to it's intended

destination.

Howev-

er, some

models

are equipped

with a voltage selector.

If

your

machine

is

so

equipped,

before

connecting,

check

to

see

that

the VOLTAGE SELECTOR

on the

rear

panel

is

set

to the voltage

for

your

area.

If not,

please

set it correctly

before

plugging

in

the

power

cord.

220Y,50H2

for Europe

except

the

UK.

240Y,50H2

for UK

and Australia.

l20Y,60Hz

for

USA

and

Canada.

If the VOLTAGE

SELECTOR

is

not set

for

your

area:

Confirm

that

the

power

cord

is disconnected.

Move

the VOLTAGE

SELECTOR

with a

screwdriver

so

that

the marker is above

the voltage

for

your

area.

What

you

should

know

to

protect

yourself

and the

Akai

PEQ6

rilatch

out!

You might

get

an electric

shock.

o Never

touch the

plug

with

wet hands.

o Always

pull

out

by the

plug

and never

the

cord.

o

Only

let

a

qualified

professional

repair or

reassemble

the equipment.

An

unauthorized

person

might

touch the

internal

parts

and receive a serious

electric

shock.

o Never

allow

a child

to

put

anything,

especially

metal, into

the equipment.

Let's

protect

the

Akai

PEQ6 too.

o

Use

only a

household AC

power

source.

Never use

a DC

power

source.

o If

water is

spilled

on

the equipment,

disconnect

the

power

and call

your

dealer.

o Make sure

that

the

equipment

is

well ventilated

and

away

from direct sunlight.

o To avoid

damage

to the internal

circuits

and the ex-

ternal

surface,

keep away

from

heat

(stoves,

etc.)

o Avoid

using spray

type insecticide

near

the

equip-

ment. It can

damage

the finishand

might

ignite sud-

denly.

o

To avoid damaging

the Íinish,

never use denaturat-

ed alcohol,

paint

thinner or other

similar

chemicals

to

clean

the

equipment.

o

Place the equipment

on

a flat and solid surface.

To enjoy

the Akai

PEQ6

for a long

time,

please

read

this

operator's

manual

thoroughly.

Should

a

problem

persist,

write down

the

model and

serial

numbers and

all

pertinent

data

regarding

warran-

ty

coverage

as

well as a clear description

ofthe existing

trouble. Then, contact

your

nearest

authorized Akai

Service Station,

or

Copy Function

The PEQ6

has 2

kinds of equalizing

data copy func-

tions.

1.

LINE

(CHANNEL)

COPY

This

is a

copy function for operations

carried

out

before

storage in the memory

banks. It allows

equalizing

data

set

at a ceÍtain LINE

channel to

be

copied'to

another LINE channel.

2. BANKCOPY
This

function

allows equalizing

data stored

at a cer-

tain

bank number

to be faithfully copied

to another

bank number.

Copying

1. LINE

(CHANNEL)

Example:

LINE

"ó"

equalizing

data set at channel

"32"

is to

be copied to LINE

"2".

Procedure

C

First,

press

the

UP button under BANK/MIDI

and

set

it to

bank

number

"32."

Next,

press

LINE and set the LINE

channel to

"6."

When

the

COPY/WRITE

button has

been

pressed

and the

"6" displayed is blinking,

press

LINE to

set

the LINE

channel to

Equalizing

Data

Clear

Function

The

PEQ6

has a function

which

can clear

all stored

equalizing

data.

Operation:

If the

POWER

is set

to ON

while

simul-

taneously

pressing

the UP

and

DOWN

buttons

under

BANK/MIDI,

the

memory

is fully

cleared,

and the

equalizing

gain

data

is all

initialized

to

the

"Flat"

state.

BANK

UP Function

Using

Foot

Switch

When a foot switch,

such

as the

AKAI

PS-X80'

is con-

nected

to the

BANK

UP

on the

front

panel,

the bank

number

can be switched

(BANK

UP) using

the foot

switch.

The bank

number

increases

by

one

each

time

the switch

is

pressed.

and it

returns

to

" 1" after

"32."

MIDI

When

shipped

from

the

factory,

the

MIDI

channel

set-

ting

on

the PEQ6

is set

to

"CH.l."

If it

is

set

to any-

thing

else,

the

lollowing

operations

should

be

per-

formed.

O

First, set

the

POWER

to

ON

while simultaneously

pressing

the

LINE

and

COPY/WRITE

buttons.

@

Next,

use

the UP

or DOWN

button

under

BANK/

MIDI

to

set

the desired

MIDI

channel

(1-16).

@

Then,

press

the LINE

button.

The number

di'-

played

will change

to

"00,"

and

the unit

will

go

ivr

normal

multi-channel

7-band

equalizer

mode.

@ Using

the UP

or

DOrilN

button

under

BANK/

MIDI, select

the bank

number.

Note:

The

new

MIDI

channel

setting

remains

stored

in memory

even

when

the

is

turned

off.
