Denon PMA-425R - Panel Control Functions

DESIGNATIONS AND FUNCTIONS OF PANEL CONTROLS
10
POWER (Power Switch)
When the power switch is turned ON (=), the MUTE/
STANDBY LED @ lights.
When the power switch is turned 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.
PHONES (Headphone Jack)
This jack is used to plug in the headphones.
SPEAKERS (Speaker Selection Switch)
The PMA-525R can be connected to two speaker systems:
speaker system A and speaker system 8. .
When A is pressed, the speaker system connected 1 to
speaker output terminals A operates.
When B is pressed, tha speaker system connected to
speaker output terminals 8 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.
SOURCE DIRECT (Source Direct Switch)
The controls (BALANCE, VARIABLE LOUONESS, and
TONE) can be used when this switch . in the OFF {.m)
position.
When set to the ON (= ) position, the above controls are
by-passed and the signals are input directly to the volume
control circuit, providing high quality sound.
VOLUME (Volume Control)
This knob controls the overall volume tevel.
Turn the knob to the right ( 7 ) to raise the volume and to
the left ( (1 } to lower it.
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. !f there is
a difference in the left and right channel output voltages for
a cartridga, move the knob to the left and the right to adjust
it. ff 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 ( 7 ). This will achieve an even balance
on the left and right sides.
BASS (Bass Control) .
This knob is used to control the bass 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 i is moved off center to
the right (7 ), and reduced as it is movedt to the left( }.
TREBLE (Treble Control)
This knob is used to controi the treble quality of the sound.
Whan 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{ O ), and reduced as itis moved to the left ( ( ).

VARIABLE LOUDNESS (Loudness Control}
At low volumes, the human ear is less sensitive ta low
(BASS) and high {TREBLE} frequencies. Use this control to
compensate for this deficiency when listening at tow
volume fevels. Turn this control counter-clockwise until a
natural batance of bass and treble sound has been
restored.
REMOTE SENSOR (Remote Control Sensor}
This sensor receives the infra-red light transmitted from the
wireless remote control unit.
For remote control, point the wireless remote control unit -
towards the sensor.
MUTE/STANDBY LED
This LED flashes while the muting circuit is activated when
the power is turned on and when muting is turned on from
the remote control unit, and remains lit (without flashing)
while the power is on. In addition, this LED flashes rapidly
when the protection circuit is activated.
TAPE SELECTOR (Tape Selector/Monitor Buttons)
@ COPY/DAT/TAPE-1:
Press this button once, COPY/DAT/TAPE-1
indicator will light up and then you can
play tape source on DAT/TAPE-1 terminal,
In this state you can copy COPY/DAT/
TAPE-1 source to DAT/TAPE-2 terminal.
Presa again the button currently accessed,
to play sources selected by input selector
@, indicator goes out.
@ DAT/TAPE-2:
Press this button once, DAT/TAPE-2 indica-
tor will light up and then you can play tape
or video source of DAT/TAPE-2 terminal.
Press again the button currently accessed,
to play sources selected by input selector
@®, indicator goes out.
INPUT SELECTOR (Input Select Switch}
Use these to select the program source.
When the switch for the desired program source is
selected, its LED tights. One program source only can be
selected at a time, as follows:
@ PHONO: Use this position when using the record
player. connected to the PHONO jacks. The
secord, player should have an “MM” car-
tridge.
e CD: Use this position when using the CD play-
*- "" @s, ete., connected to the CD jacks.
Use this ‘position when using the tuner,
etc., connected to the TUNER jacks.
Use this position when using the compo-
nent connected to the AUX jacks.
@ TUNER:
e AUX:
PMA-525R only
@ Ac OUTLETS: Rear Panel Side

AC outlets are used for connecting amplifier com-
ponent units, such as tuner, turntable, tape deck,
atc.

is on or OFF.
e@ For Europe model, except the U.K. and Australia
models.
AC outlets are used for connecting amplifier com-
ponent units, such as tuner, turntable, tape deck,
etc.
e@ SWITCHED {Total capacity: 100 W):

mote Control Unit is turned on/off,
@ UNSWITCHED (Capacity: 100 W)
This outlet is always ON whether power switch
is on or OFF.
OPERATION
PREPARATION
1, CHECKING CONNECTIONS
Make sure that all the connections are proper by referring to
the back panel. (Fig. 2~3)
eCheck the polarity (positive and negative) of connections,
and the directivity of stereo separation (right cord to right
channel terminal, and left cord to left channel terminal).
eCheck the directivity of pin cord connection.

TAPE-1.
MONITORING THE RECORDING
{If a 3-head tape deck is used, the sound being recorded can be
monitored during the recording.)
Use the TAPE MONITOR switches @ to select the tape deck onto
which the sound is being recorded.
The LED for the selected tape deck lights.
CAUTION
Protective Circuit
This set is equipped with a high speed protective circuit.
This circuit protects the internat circuitry from damage due
to Jarge currents flowing when the speaker jacks are not
completely connected or when an output is generated by a
short circuit. This protective circuit's operation cuts off the
output to the speakers. In such a case, be sure to turn the
power to the set off and check the connections to the
speakers. Then turn the power on again. After muting for
few seconds, the set will operate normally.
