Adjustment

of

the

gain

reduction

frequency

response

is

accomplished

by

control

R37

which

is

located

on

the

rear

of the

LA-2A.

Increasing

the

resistance

of

R37

reduces

the

amplitude

of

the

low

frequency

voltage

applied

to

the

Peak

Reduction

control,

R2.

The

high

frequency

com-

ponents

are

not

affected

because

of the

low

reac

tance

of C 12.

Thus,

if

the

control

is

set

to

the

"flat"

position

the

LA-2A

will

provide

equal

gain

reduction

on

all

frequencies.

If

the

control

is

moved

away

from

the

"flat"

position,

the

leveling

will

be

greater

on

the high

frequencies.

The

actual

setting

can

be

best

determined

on

program

material

for

a

compromise

between

low

and

high

frequency

limiting.

Maximum

high

frequency

response

will

provide

approximately

10 DB

more

reduction

at

15

KC

than

at

frequencies

below

1 KC.

230

VOLT

INPUT

The

LA-2A

is

set

for

a

power

line

voltage

of 115V

when

shipped.

In

order

to

change

this

for

230

volts,

open

the

front

panel

and

make

the

following

changes:

Locate

the

vertical

solder

terminal

strip

at

the

right

hand

end

of the

chassis.

Terminal

1

is

connected

t02,

and

3

is

con-

nected

to 4

for

115V

operation

.

Remove

these

jumper

wires

and

connect

terminal

2 to 3.

This

will

allow

operation

on 230

volts

±10%, 50/ 60

cycles.
