enough.

The

subsonic

fi

lter

reduces

these

inaudible

frequencies

at

6dB

per

octave

below

15Hz.

The

audible

portion

of

the

frequency

range

will

not

be

affected,

so

it

is

useful

to

leave

the

subsonic

fi

lter

on

at

all

times

when

listening

to

the

turntable.

The

indicator

light

will

be

lit

when

the

SUBSONIC

fi

is

on.

o

TONE

DEFEAT

switch

When

TONE

DEFEAT

is

turned

on,

the

bass

and

treble

controls

have

no

effect.

The

TONE

DEFEAT

switch

internally

bypasses

the

tone

control

circuitry,

resulting

in

completely

unaltered

frequency

response.

If

you

want

to

use

the

bass

and

treble

controls,

turn

TONE

DEFEAT

off.

The

indicator

light

will

be

lit

when

the

TONE

0

BASS

control

The

BASS

control

boosts

or

reduces

the

low

frequency

sound

level.

The

BASS

control

affects

only

frequencies

below

300Hz,

and

allows

changes

of

up

to

±10dB.

The

BASS

tone

control,

in

some

circumstances,

can

help

you

adjust

the

overall

sound

of

your

system.

For

example,

"boomy"

room

acoustics

may

be

improved

with

a

slight

decrease

in

the

bass,

or

the

sound

of

smaller

loudspeakers

lacking

in

bass

may

be

improved

with

a

bass

boost.

TREBLE

control

The

TREBLE

control

boosts

or

reduces

the

high

frequency

sound

level.

The

TREBLE

control

affects

only

frequencies

above

3000Hz,

and

allows

changes

of

up

to

±10dB.

The

TREBLE

tone

control,

in

some

circumstances,

can

help

you

adjust

the

overall

sound

of

your

system.

For

example,

an

overly

shrill

recording

or

"bright"

room

acoustics

may

be

improved

by

a

reduction

in

the

amount

of

treble.

e

BALANCE

CONTROL

The

BALANCE

control

distributes

the

sound

between

the

right

and

left

speakers.

For

equal

balance

in

each

channel,

set

the

control

in

the

center.

VIDEO

®

CARTRIDGE

selector

This

switch

sets

up

the

gain

and

input

impedance

of

your

amplifier's

internal

circuitry

to

match

the

type

of

cartridge

being

used

on

your

turntable.

Be

sure

you

connect

your

turntable

to

the

appropriate

PHONO

input

jacks

on

the

back

of

the

HK

6800/6900

(MM

for

moving

magnet

cartridges,

or

MC

for

moving

coil

cartridges).

Then

use

this

switch

to

select

the

type

of

cartridge

mounted

on

your

turntable.

Note

that

you

can

connect

both

moving

coil

and

moving

magnet

cartridge

inputs

and

use

this

switch

to

select

between

them.

The

MC

setting

engages

a

special

MC

the

sound

level.

Turn

the

VOLUME

control

all

the

way

down

before

you

turn

on

your

amplifier

or

change

sound

source.

This

will

protect

your

speakers

from

being

damaged

by

sudden

high
