Earthlng IMPORTANT

-

Both

mixers

are hard-ear1hed,

ie.

mains

earthed

equipment.

Lift the

signal

eafth

from

all other

ancillary

equipment

to

avoid earth

.

loops,

which

create

unwanted

buzz

and

hum.

Under

no clrcumstances

should

you

disconnect

the

earth

wlre

ln

the maln

AC supply

of any

ancillary

equlpment.

Consult

the

relevant

manual

supplied

in order

to lift

the

signal

earth

correctly.

The Citronic

SPX

range of

processors

are sott-earthed

and

no

adjustment

is

required

for complete

compatibility

with the

SM

range.

The PPX

range of amplifiers

feature

an earth

lift switch

on the

rear

panel,

enabling

you

to harmonise

your

sound

system

by using

only

top

quality

Citronic

products.

Power supply The mixer is supplied

with

it's own separate

power

supply

unit which may

be

mounted

in any

position.

Care should

be taken,

however,

to ensure that

there

is adequate

ventilation

around

the

power

supply

heatsink,

and

that

all

signal

wiring is

routed away

from

the

power

supply.

The voltage rating

is

factory

set to

match

European

and

U.K.

standards,

ie.

220-240V.

Check this

setting

on the

rear

of

the unit.

For use

in Canada

and the USA,

the

voltage

rating should

be set

at 110

-120V.

ln

order

to comply

with

international

safety

standards,

power

supplies

are

fitted with

a moulded

multi-standard

mains

plug.

For

use

in the U.K.

this

plug

will need

to

be

replaced

with a standard

13

amp

plug

fitted

with a 3

amp

fuse.

Slgnal connectlons

Make

all connections

to turntable,

CD

and tape decks using

good

quality

stereo

phono

or RCA

phone

Jack leads. The

importance

of this is often

overlooked,

and is the frequent

cause

of complaints

about

poor performance

and

output

quality.

lmportant

note:

been

supplied

with four

Jump

leads which

you

may

need

to insert,

please

refer

to

the

section

"lnstallation

be switched

directly.

As

with

all equipment,

if

you

are

in any

doubt,

consult

your

dealer.

Packaging Ensure

that

all faders

are set

at the

maximum

before

MAINTENANCE

AND GUARANTEE

Maintenance

NO SPECIAL

PREVENTATIVE

MAINTENANCE

IS

R EQU

IH ED

As with

all

high

quality

audio

equipment,

the

overall

performance

is

highly

leads.

lt is

therefore

essential

that

these

are checked

periodically

for

wear

and tear

and

replaced

as

necessary.

Although

all Faders

are

vedically

mounted,

it

is

still

important

to

avoid

spilling

liquid

onto

your

mixer,

as this

may

cause

damage

to

the

precision

electronics.

This

product

is

guaranteed

to the

original

purchaser

against
