BALANCED INPUT

CONNECTORS

{XLR)

The

XLR

connector

is

compatible

with

balanced inputs. Since

the

XLR

connector

is

internally

wired

in

parallel,

you can

parallel

this

unit

with another amplifier

by

using

the XLR to

outputthe

signal

to the

input

connectors

of the

other amplifier. Balanced

connections

are

recommended

as

they

are

less prone

to AC

than

600

ohms

is

needed

to

avoid signal loss.

For

short cable

runs

an

unbalanced signal input should

be

suitable.

For

stereo

(two-channel)

operation,

use

the

inputs

for

both

CH-1

and

CH-2;

for

parallel

or

bridged

mono operation,

use

only

CH-1

input.

(See

MODE SELECTOR SWITCH below

for

more explanation.)

MODE SELECTOR SWITCH

The

MA

Series

amplifiers offer

3

modes

of

operation;

PARALLEL,

STEREO

&

BRIDGED.

Slide

the

switch

to one

ofthe three

.

PARALLEL

(MONO)

INPUT

-This

mode

allows

both channels

to

operate

in

parallel

with

the

same signal

and

without requiring

a

Y-cord.

In

this mode

the

inputs

for

both channels

are

internally

connected,

so

that

you

only need

to

feed

a

signal into

one

of

the

channels, This

still

allows independent

level

control

amps

by

using

the

other channel

of

input connectors.

(Note:

Do not

select

this

"Parallel"

mode when feeding

the

amplifier

with

2

separate

signals.)

(Note:

Do

not

use

both unbalanced

and

balanced cables

in the

same

set-up

as

that

can

unbalance

all the

connections when

daisy-chaining,

resulting

in

hum.)

.STEREO

INPUT -This

is

the

most common mode generally

used,

and

allows

independent

control

of 2

separate signals

such

as

stereo

playback, main

and

monitor live mixes,

and bi-

arnp

operation (highs

in one

channel

and

lows

in the

other).

.BRIDGED

MONO-

This

mode

combines

the

power

of

both

channels

!o

drive

a

single speaker.

In

this mode

the amp

produces

4

times

the

peak power

and 3

times

the

sustained

separately

in

stereo

or

parallel mode.

(CAUTION:

Inthis

mode

the

amplifier

can

deliver high

power

wiring

can

handle this output.

Note

that

for

prolonged

blow,

so

care

musi

be

taken

not to

overload

the

amplifier

such
