slowly

apply

PROTECTION

CIRCUITRY

The

protection

circuitry

may

have

operated

if

either

of

the

following

conditions

is

noticed:

*No

sound

is

heard

when

the

power

is

switched

ON.

“Sound

stops

during

a

performance.

The

function

of

this

circuitry

is

to

prevent

circuitry

damage

if,

for

example,

the

positive

and

negative

speaker

connection

wires

are

“shorted”,

or

if

speaker

systems

with

an

impedance

less

than

the

indicated

rated

impedance

of

this

unit

are

used.

If

this

occurs,

follow

the

procedure

outlined

below:

1.

Switch

OFF

the

power.

2.

Determine

the

cause

of

the

problem

and

correct

it.

3.

Switch

ON

the

power

once

again.

Note:

When

the

protection

circuitry

functions,

the

unit

will

not

operate

unless

the

power

is

first

switched

OFF

and

then

ON

again.
