e CONNECTING THE SPEAKERS
Connect the cords for the left speakers to the L
terminals and the right speaker cords to the R
terminals, ensuring that the polarity (+ and
—) markings are observed. Be sure to do this
consistently from component to component. If
the polarity is reversed at either speaker the
sound will be unnatural and lack bass. Speaker
cords should be cut as short as possible. Avoid
coiling the wire on the floor or bundling it up
with cords from other system components.
The AX-500U speaker terminals allow for two
connection methods. The first method outlined
usually provides a more secure connection.
1. Strip about tem of insulating material from
the ends of the speaker wires and twist the
strands of each end. Loosen the speaker
terminal knobs, insert the exposed wire into
the hole and then tighten the speaker terminal
Knobs.
RED for (+) sign.
BLACK for (—) sign.
2. Banana Chip connections are also possible.
Simply insert the Banana Chip connector into
the corresponding terminal.
® CONNECTING A TURNTABLE
Connect the output cords of the turntable to the
Phono jacks and connect the ground wire to the
GND terminal. Normally connecting the ground
wire produces minimum hum but in some cases
better results are obtained with the ground wire
“disconnected. The turntable component and its
output cords should be positioned well away
from sources of hum such as power cords or
power transformers of other system compo-
nents.
e CONNECTING A TUNER
Connect the cords from the tuner's output jacks
to the TUNER jacks of the amplifier. Position the
tuner so that its AM antena is well away from
the amplifier for the best possible reception.
e CONNECTING TO THE CD AND VIDEO/AUX
JACKS
Connect your CD component to the CD terminals
and video sound output leads to the VIDEO/AUX
terminals. Please note that a turntable cannot
be connected to the these jacks as they do not
provide the necessary RIAA equalization.
® CONNECTING TAPE DECKS
TAPE DECK 1. |
Connect the cords from the tape deck's Line In
jacks to the REC OUT jacks of TAPE 1, ensuring
thatleft and right are not reversed. Then connect
the cords from the tape deck's Line Out jacks to
the Tape 1 PB jacks.
TAPE DECK 2 can be connected in similar
fashion to the Tape 2 terminals.
@® AC OUTLETS
For added convenience the AX-500U provides
3 AC outlets. Two “switched” outlets (the power
to these receptacles is turned on and off by this
unit's power switch) and one “unswitched”
outlet (the power to this receptacle is inde- —
pendent of this unit's power switch). Be sure not
to connect appliances totaling more than 80
watts to the 2 switched outlets or 200 watts to
the unswitched outlet.
® ACCESSORY |
The Accessory option allows you to connect a
signal processing system, such as an equalizer,
in the signal path prior to the Tone control,
Connect the Accessory send jacks to the inputs
ofthe equalizer andthe Accessory Receive jacks
to the outputs of the equalizer.

@ POWER SWITCH (POWER) @ POWER ON INDICATOR © SPEAKERS SWITCHES (SPEAKERS)
Press once to turn the power ON and once again Illuminated when the power is ON. As one or two speaker systems can be connected
to turn the power OFF. Before turning the power | to the AX-500U, these switches allow you to
ON set the volume to its lowest position (extreme | | selectspeaker system A, Bor both atonce. When
counterclockwise), to protect the speakers from | listening to the headphones only press both the
any sudden high level sound. A and B switches to the OFF position.
O TONE BYPASS CONTROL SWITCH
(TONE EYPASS)
Depress this switch to channel the input signal
directly to the output stage of your amplifier,
bypassing the Bass and Treble controls there-
fore avoiding any “muddying” caused by the
switch and circuit routing to provide a pure
sound.
O INPUT SELECTOR PANEL
Selects the program source you wish to listen
to. The indicator LED above the selected source
will light up.
@ CD DIRECT SWITCH (CD DIRECT)
This switch allows you to route the CD input
signal directly to the output stage bypassing the
Mode, Loudness, and Balance controls there-
fore avoiding any “muddying” caused by the
switch and circuit routing to provide a pure
sound.
€ VOLUME CONTROL KNOB (VOLUME)
This controls the sound level. Turning clockwise
increases the sound volume and turning coun-
terclockwise decreases it. Set this knob to the
minimum level before turning the power ON or
using the Input Selector Panel to select a dif-
ferent sound source, therefore, protecting the
speakers from any sudden high level sound.
E) REC OUT SELECTOR (REC OUT)
This switch will select a program source and
feed that source directly to the rear panel REC
OUT terminals independent of the INPUT SE-
LECTORS. This function therefore allows you to
listen to any input source while recording an-
other. This control also permits you to record
directly from Tape 1 to Tape 2 or vice versa.
O PHONO SELECTOR SWITCH (PHONO)
Selects either MM (moving magnet) or MC
(moving coil) position to match your cartridge.
High performance MC cartridges can be used
when in the MM position.
() MODE SWITCH (MODE)
Permits switching between stereo and mono
operation. Normally this switch should be set to
the stereo position.
O SUBSONIC FILTER CONTROL SWITCH
(SUBSONIC)
This switch cuts out ultra low frequency signals
caused by turntable rumble or warped records,
yet retains sound quality.
(» LOUDNESS CONTROL KNOB (LOUDNESS)
This control provides compensation for the hu-
man ears loss of sensitivity to high and low
frequency ranges atlow volumes. As the amount
of compensation required is determined by the
listening level, this control provides the most
accurate compensation for any listening level.
Set it to the flat position while the volume control
is set to your normal listening level. Turning it
counterclockwise will decrease the volume
while retaining the natural balance of low and
high frequencies.

® BALANCE CONTROL KNOB (BALANCE)
This knob is used to adjust the relative volume
of the left and right channels, enabling you to
compensate for unbalance created by installa-
tion locations of the speakers.
{{ TREBLE CONTROL KNOB (TREBLE)
‘This knob controls treble response. Turn it
clockwise to boost or counterclockwise to at-
tenuate treble response. When this knob is in
the center defeat position a flat response is ob-
tained.
® BASS CONTROL KNOB (BASS)
This knob controls bass response. Turn it
clockwise to boost or counterclockwise to at-
tenuate bass response. When this knob is in the
center defeat position a flat response is ob-
tained.
O HEADPHONES JACK (PHONES)
