About the accessory terminals
e AC OUTLETS (EXCEPT EUROPE MODEL)
Use these to connect the power cords from your
components to this unit.
The power to the SWITCHED outlets is controlled by
this unit's POWER switch. They will supply power to
any component whenever this unit is turned on.
<AX-550>
U.S.A. and General Models
The maximum power (total power consumption of
components) that can be connected to the SWITCHED
AC OUTLETS is 200 watts.
Canada Model
The maximum power (total power consumption of
components) that can be connected to the SWITCHED
AC OUTLETS is 80 watts.
<AX-450>
U.S.A. and General Models
The maximum power (total power consumption of
components) that can be connected to the SWITCHED
AC OUTLETS is 200 watts.
Canada Model |
The maximum power (total power consumption of
components) that can be connected to the SWITCHED
AC QUTLETS is 100 watts.
e GND terminal (For turntable use)
Connecting the ground wire of the turntable to this
terminal will minimize hum, but in some cases better
results may be obtained with the ground wire
disconnected.
e PRE QUT/MAIN IN terminals <AX-550 Only>
Removing the jumper pins enables this unit to
independently perform the functions of a control
amplifier and a power amplifier. These terminals are for
connection of a signal-processing system such as a
graphic equalizer or sound processor.
If a sound processor or other component is connected,
the VOLUME control of this unit can be used for overall
adjustment of the level of sound. To connect such a
unit, remove the jumper pins from the PRE OUT/MAIN
IN terminals, connect the inputs of that unit to the PRE
QUT terminals and its outputs to the MAIN IN
terminals. For details, refer to the Owners Manual
included with the unit to be connected.
COUPLER
REMOTE CONTROL (PHONO) connector
<AX-550 Oniy>
If you have a YAMAHA turntable with the =#= mark,
connect it to this connector by using the cable provided
with the turntable. This connection allows you to control
the turntable from the provided remote control
transmitter.

Using the PURE DIRECT switch
You can enjoy purer source sound by setting this switch
so that the indicator illuminates. Because, by doing so,
the input signal is output directly, bypassing the MODE
switch (AX-550 only), BASS, TREBLE, BALANCE,
LOUDNESS controls and SUBSONIC FILTER switch,
therefore avoiding any “muddying” caused by circuit
routing.
~ Concerning AX-550 only, the PRE OUT/MAIN IN terminals
are also bypassed. |
Setting the SUBSONIC FILTER
if you set the switch to the ON position, ultra-low-

records can be cut out without losing sound quality.

The remote-control transmitter provided with this unit is designed to control all the most commonly used functions of the
unit. if the CD player, turntable, equalizer, tuner, and tape deck connected to this unit are YAMAHA components designed
for remote control compatibility (components with an == mark), then this remote-control transmitter will also control
various functions of each component. Please consult YAMAHA dealer for information on which components are compatible
with the remote-control transmitter.

records.
The input wires are not connected securely.
Connect the input wires securely.
The turntable's ground wire is not connected.
Connect the ground wire.
There is a howling sound when playing
records at high volume.
The turntable and the speakers are too close
together, or the turntable is not located on a firm
surface.
Change the location of the turntable or the
speakers.
Using the MODE switch (AX-550 only),
