The

BIAS

FINE

TRIM

knob

(21)

allows

you

to

adjust

recording

bias

optimally

for

different

brands

and

formulations

of

tape.

Adjustment

is

not

necessary

for

playback.

To

determine

the

proper

adjustment,

make

a

trial

recording

from

a

record

you

know

well,

and

compare

the

record

to

the

tape

recording.

If

the

tape

provides

exces-

sive

high

frequency

response,

rotate

the

BIAS

FINE

TRIM

knob

(21)

counterclock-

wise

toward

the

hi

cut

setting.

If

the

tape

lacks

high

frequency

response,

rotate

the

BIAS

FINE

TRIM

knob

(21)

toward

the

hi

boost

position.

Continue

trial

recordings

until

the

high

frequency

response

on

the

tape

recording

and

record

are

as

close

as

possible.

This

is

the

correct

setting

only

for

the

particular

formulation

and

brand

of

tape

in

use.

If

you

continue

to

use

the

same

for-

mulation

and

brand,

readjustment

is

gen-

erally

not

necessary.

But

new

adjustments

should

be

made

for

different

tapes.

Output

control

A

convenient

OUTPUT

LEVEL

control

(23)

is

incorporated

into

the

hk100M

to

match

the

output

level

of

your

tape

deck

with

all

your

other

equipment.

This

pre-

vents

bursts

of

high

volume

when

switch-

ing

from

one

program

source

to

another.

Headphones

During

recording,

you

may

wish

to

monitor

the

program

source

with

head-

phones.

The

jack

marked

HEADPHONES

(22)

is

included

for

this

purpose.

We

rec-

ommend

low

impedance

headphones

(less

than

1000

ohms).

With

headphones

in

use,

volume

may

be

adjusted

with

the

OUTPUT

LEVEL

control

(23).

Dolby*

NR

To

improve

signal-to-noise

ratio

on

all

recordings,

the

DOLBY

NR

system

should

be

used

both

for

recording

and

playback.

To

engage

the

Dolby

NR

system,

press

the

DOLBY

NR

button

(17)

to

its

"on"

posi-

tion

(in).

Whenever

the

Dolby

NR

system

is

engaged,

the

DOLBY

NR

indicator

(14)

will

light.

Tapes

recorded

with

Dolby

NR

should

be

labeled

so

you

remember

to

engage

the

system

during

playback.

NOTE:

In

some

cases,

recordings

from

FM

broadcasts

may

contain

more

noise

than

was

apparent

during

the

origi-

nal

broadcast.

To

prevent

this,

place

the

MPX

FILTER

switch

(18)

in

its

"on"

position

while

recording

from

FM

broadcasts.
