FACILITIES

@ POWER SWITCH

Set this switch to ON to supply power to the

amplifier. There will be a short delay when it is

set to ON, because the muting circuit has been

actuated to suppress the unpleasant noise that is

sometimes generated when the power is on and

off.

@ POWER INDICATOR

When the power switch is set to ON this lamp

lights up, indicating the amplifier is turned on.

@) SPEAKER SELECTOR

@ TAPE MONITOR INDICATOR

The TAPE lamp lights up when the tape monitor

switch is set to either position ''1" or "'2''.

©) POWER METER

This

meter

allows

you

to read

out

the rated

power level on the fluorescent display tube when

speakers with a nominal impedance of 8 ohms are

connected to the amplifier's speaker terminals.

The PHONO,

TUNER,

AUX

function indicators

light up in accordance

with the position of the

function selector.

NOTES:

The

function

indicator

will not go off when

the tape

monitor

switch

is set to position

'1' or

'2"',

@: LOUDNESS SWITCH

When listening to a performance with the volume

control turned down, set this switch to ON and

the bass and treble will be accentuated.

When

the volume

is low, the human ear finds it

harder to hear the bass and treble than when the

volume

is high.

The

lotidness

switch

is thus

designed to compensate

for this deficiency. By

setting it to ON, the bass and treble come through

much

strongly and the sound takes on a

punch even when the volume control is turned

down.

VOLUME CONTROL

Use this control to adjust the output level to the

speakers and headphones.

Turn it clockwise to

increase the output level. No sound will be heard

if you set it to oo. The scale is graduated in dB

which

indicate the attenuation when the max-

imum output level is OdB.

@ TAPE DUPLICATE SWITCH

Use this switch when employing two tape decks

to duplicate

recorded

tapes or edit tapes. This

switch is otherwise kept at the OFF position.

nected to the TAPE 1 jacks and recording
