is

obtained

when

adjusted

by

changing

the

out-

of

ranges

upward

by

up

to

10

dB.

The

are

adjustable

both

upwards

in

5

steps

of

2

dB

each.

Upward

movement:

Press

the

The

is

in-

creased

Press

The

one

step

each

press-

Operation

is

the

same

for

both

the

right

and

left

channels.

Increasing

output

at

this

frequency

will

boost

bass

sound,

such

as

from

a

pipe

organ

or

contra-

bass,

to

provide

a

sense

of

weight

and

stability.

Decreasing

output

at

this

frequency

will

eliminate

hazy

bass

tones

to

produce

clear

sounds.

This

control

is

used

to

adjust

the

level

of

low

fre-

quency

signals.

Moving

the

control

in

upward

direction

will

help

to

increase

bass

tones

from

small

size

speakers.

This

control

is

mainly

used

to

adjust

level

of

vocal

sounds.

Move

the

control

up

and

down

to

obtain

suitable

vocal

sounds.

The

strength

or

weakness

of

a

sound

is

promi-

nent

at

this

frequency.

Increasing

output

at

this

frequency

will

effec-

tively

enhance

musical

presence.

This

frequency

is

the

most

striking

part

of

the

sound

to

listeners.

Increasing

output

at
