Volume,

balance,

loudness

and

tone

controls

To

increase

the

volume,

turn

the

VOLUME

control

(26)

clockwise.

The

BALANCE

control

(20)

shifts

the

sound

to

one

speaker

or

the

other.

The

BASS

and

TREBLE

controls

(13) (14)

affect

the

frequency

balance

of

the

program

material

.

Their

neutral

positions

are

at

12

o'clock.

Turning

the

TREBLE

control

(14)

clockwise

increases

the

high

frequencies.

The

BASS

control

(13)

has

the

same

effect

on

low

frequencies.

When

the

LOUDNESS

button

(27)

is

in

its

"on"

posi-

tion

(in),

very

high

and

very

low

frequencies

are

boosted

at

low

settings

of

the

VOLUME

control

(26).

This

com-

pensates

for

the

ear's

relative

insensitivity

to

extreme

fre-

quencies

at

low

volume

levels.

The

LOUDNESS

button

(27)

has

very

l

ittle

effect

at

volume

settings

beyond

12

o'clock.

Mono/stereo

blend

The

MONO/STEREO

BLEND

control

(21)

al

lows

you

to

compensate

for

a

variety

of

speaker

placements.

Ideally,

the

distance

between

the

speakers

should

be

about

the

same

as

the

distance

from

the

l

istener

to

a

point

midway

between

the

speakers.

Under

these

conditions,

the

MONO/STEREO

BLEND

control

(21)

should

be

in

its

full

stereo

position

(ful

l

clockwise).

If

the

distance

between

the

speakers

is

substantially

greater

than

the

distance

to

the

listener,

stereo

imaging

may

be

improved

by

rotating

the

MONO/STEREO

BLEND

control

(21)

counterclockwise

toward

the

mono

setting.

Filters

and

tone

defeat

The

hk1680

also

incorporates

three

additional

controls,

a

SUBSONIC

FILTER

(11),

a

TONE

DEFEAT

(10)

and

a

HIGH

CUT

filter

(12).

Placing

the

TONE

DEFEAT

button

(10)

in

its

"on"

position

(in)

eliminates

the

action

of

the

BASS

and

TREBLE

controls

(13)

(14)

to

allow

for

critical

evaluation

of

their

effect.

Placing

the

SUBSONIC

FILTER

button

(11)

in

its

"on"

position

(in)

engages

a

filter

to

pro-

tect

your

speakers

from

inaudible

low

frequency

signals

caused

by

severe

record

warp,

acoustic

feedback

or

tonearm

resonance.

Placing

the

HIGH

CUT

fi

lter

button

(12)

in

its

"on"

position

(in)

minimizes

"hiss"

and

other

high

fre-

quency

noises.
