FUNCTIONS
OF PANEL CONTROLS
o ©
POWER
(Power Switch)
When
the power switch
is turned
ON
(-m), the tuner
function indicator lights.
When the power switch is pressed ON, power is supplied to
the unit. It 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.
INPUT SELECTOR
(Input Select Switch)
This switch
is used to select the input signal for the
program source.
e
PHONO:
Used to select the output from a turntable
that is connected to the PHONO terminal.
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
to play a component
such
as an
FM/AM
tuner or a TV tuner that is con-
nected to the TUNER
terminal.
Used to play a component such as a Hi Fi
video player, TV tuner, 8-track tape player
or tape deck that is connected to the AUX-1
or AUX-2 terminal.
*
The
PMA-320A
uses
a high performance
electronic
switch for this function. When the power is turned ON,
the position of the INPUT SELECTOR switch is automati-
cally set to TUNER.
*
{fa function switch is pressed quickly, the function may
not actually change and no signal may be heard from
the speakers for an instant. To avoid this, be sure to
press function switches carefully. Even if the function
does
not change
and
no signal is heard from the
speakers
for an
instant
when
a function
switch
is
pressed, this will not affect copies.

VOLUME
(Volume Control)
This knob controls the overall volume
level.
Turn the knob to the right ( O ) to raise the volume and to
the left
(© ) to lower it.
MONITOR/COPY
(Tape Monitor/copy Switch)
Set this switch to "SOURCE" for tape deck recording. The
signal from the program source selected by the FUNCTION
switch
will then
be output from the REC terminals for
TAPE-1
and TAPE-2.
When using two tape decks to make a recording of one tape
onto another, set the switch to either "TAPE-1
/ 1>2" or
"TAPE-2 / 2>1."
The "TAPE-1 / 12" position is used to play the tape deck
that is connected to the TAPE-1
terminal.
The "TAPE-2 / 21"
position is used to play the tape deck
that is connected to the TAPE-2 terminal.
PHONES
(Headphone Jack)
This jack is used to plug in the headphones.
SPEAKERS
(Speaker Selection Switch)
The PMA-320A 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.
TREBLE
(Treble Control)
This knob is used to control the treble quality of the sound.
When the knob is set at the center position, the frequency
characteristics are flattened in the range above 1000 Hz.
The treble is emphasized as the knob is moved off center to
the right ( C) ), 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 channel output voltages for
a cartridge, move the knob to the Jeft and the right to adjust
it. If the volume on the right side is too low, turn the knob to
the right ( (> ). 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.
CD DIRECT
(CD Direct Switch)
Use when
playing the CD player connected
to the CD
DIRECT terminals.
When
this position
is selected, the
signals
input from
the CD
DIRECT
terminals
skip the
MONITOR/COPY
INPUT SELECTOR
and are input directly
to the control circuit, preventing
loss of sound
quality.
*
The CD DIRECT switch has priority over the FUNCTION
switch.
Loudness can be used in this position. The signal output
to the TAPE REC terminal when CD DIRECT is selected is
the signal indicated
by the position of the Function
Switch.
The CD DIRECT terminals are exclusively for playback,
and cannot
be used for recording.
SUBSONIC
(Subsonic Filter Switch)
Use to prevent subsonic speaker vibration due to vibration
of the player motor or a warped record, etc., when playing
a connected
player.
PHONO
(Cartridge
Selection
Switch):
Back
Panel Side
This switch
is set according to the type of player
cartridge to be used.
e MC (-=):
Used when an MC (moving-coil) car-
tridge with an output of less than
0.5 mV is used.
Used when an MM (moving-magnet)
cartridge with an output of 2 mV or
more
is used.
