DESIGNATIONS
AND
FUNCTIONS
OF PANEL CONTROLS
POWER
(Power Switch)
When
the power switch is turned ON
(-=), the power
function
indicator lights.
When the power switch is turned ON, power is supplied to
the unit. lt takes a few seconds after the power is turned on
for the unit to warm up. This is due to the built-in muting
circuit that eliminates noise during the on/off operation.
PHONES
(Headphone Jack)
This jack is used to plug in the headphones.
SPEAKERS (Speaker Selection Switch)
The PMA-360
can be connected to two speaker systems:
speaker system A and speaker system
B.
When A
is pressed,
the speaker
system
connected
to
speaker output terminals A operates.
When B
is pressed,
the speaker
system
connected
to
speaker output terminals
B operates.
When
A and B are pressed
on together,
both speaker
systems
operate
simultaneously.
When
the
A
and
B
switches
are both off (in the out position), there is no
output from the speaker terminals. This setting is used to
listen to playback through the headphones.
BASS (Bass Control)
This knob is used to control the base quality of the sound.
When the knob is set at the center position, the frequency
characteristics are flattened in the range below 1000 Hz.
The bass is emphasized as the knob is moved off center to
the right ( ~) ), and reduced as it is moved to the left ( () ).
When
volume control
@ is set to the right of the center
position, the effect of the other controls is reduced.

BALANCE
(Balance Control)
This knob is used to adjust the balance between the left and
right channels. When
it is set to the center position, the
amplitude of the amplifier is equal on both sides. If there is
a difference in the left and right channe! output voltages for
a cartridge, move the knob to the left and the right to adjust
it. lf the volume on the right side is too low, turn the knob to
the right ( C) ). If the volume on the left side is too low, turn
the knob to the left ( () ). This will achieve an even balance
on the left and right sides.
LOUDNESS
(Loudness Switch)
When the volume is low, it is difficult for the human ear to
clearly distinguish notes in the low and high frequency
ranges. The loudness switch allows a simple "one-touch"
correction of this difficulty. Press the loudness switch ON
(=)
when
listening to music at a low volume. The low
notes and high notes will be corrected to produce a natural
sound.
INPUT
SELECTOR
(input Select Switch)
This switch
is used
to select the input signal for the
program source. The source to be recorded is also selected
with this switch.

Use the PHONO switch ® (Back Panel Side)
to switch the sensitivity to correspond to
the cartridge type being used.
Used to listen a compact
disc player or
other component that is connected to the
CD terminal.
Used

nected to the TUNER terminal.
Used to play a component such as a Hi Fi
e TUNER:
e
AUX:

or tape deck that is connected to the AUX
terminal.
When
using two tape decks to copy
'from
one
tape
to another,
set the
switch
to either
"TAPE-1
> 2" or
"TAPE-2
> 1".
The "TAPE-1
> 2" position is used to
copy from tape deck 1 to 2.
The "TAPE-2 >» 1" position is used to
copy from tape deck 2 to 1.
Set TAPE MONITOR switch @ to "ON
(= )" to monitor the source
being
e
TAPE-1
> 2
e
TAPE-2
> 1
recorded.
TAPE SELECTOR
(Tape Selector Switch)
This switch is used to select the source to be played back
when TAPE MONITOR
switch @ is "ON (-=)".
The "1: {_m)" position is used to play back the tape deck
connected to TAPE-1.
The "2: (m= )" position is used to play back the tape deck
connected to TAPE-2.
TAPE MONITOR
(Tape Monitor Switch)
e
When this switch is "ON (-= )", the source selected by
TAPE SELECTOR switch @ will be played back.
e
When this switch is "OFF ( m )", the source selected by

However, since "TAPE-1
>» 2" and "TAPE-2 > 1" of the
INPUT
SELECTOR
switch
are
positions used
for
copying, playback will not be possible.
