We Want You Listening For A Lifetime
YAMAHA and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that lets the
sound come through loud and clear without annoying blaring or
distortion – and, most importantly, without affecting your
sensitive hearing. Since hearing damage from loud sounds is
2
often undetectable until it is too late, YAMAHA
and the Electronic Industries Association’s
Consumer Electronics Group recommend you to
avoid prolonged exposure from excessive
volume levels.
Caution: Read this before operating your unit

ABOUT THE ACCESSORY COMPONENTS ON THE REAR PANEL
AC OUTLETS (SWITCHED)
(U.S.A., Canada, Europe and General models)
............................................................3 SWITCHED OUTLETS
(Australia and U.K. models)..................1 SWITCHED OUTLET
Use these to connect the power cords from your components
(except a power amplifier, integrated amplifier and receiver) to
this unit.
The maximum power (total power consumption of
components) that can be connected to the SWITCHED AC
OUTLETS is 200 watts. Strictly be careful not to exceed this
value.
The power to the SWITCHED outlets is controlled by this unit’s
POWER switch or the provided remote control transmitter’s
POWER key. These outlets will supply power to any
component whenever this unit is turned on.
PHONO switch
Select either MM or MC position depending on your PHONO
cartridge, Moving Magnet or Moving Coil type. However, if you
use a high output MC cartridge, select MM position.
CARTRIDGE LOAD switch <For CX-1 only>
Set to either impedance position (220Ω or 1 kΩ) proper for the
PHONO MC cartridge being used by your turntable.
GND terminal (For turntable use)
Connecting the ground wire of the turntable to this terminal will
normally minimize hum, but in some cases better results may
be obtained with the ground wire disconnected.
REMOTE CONTROL (POWER AMP)
connector
If you have the YAMAHA power amplifier MX-1 or MX-2,
connect this connector to the REMOTE CONTROL (PRE
AMP) connector of the power amplifier by using the provided
cable. By this connection, the power of the power amplifier is
controlled by this unit’s POWER switch or the provided remote
control transmitter’s POWER key.
After the connection is completed, keep the POWER switch of
the power amplifier pressed inward (to the ON position).
Note
If you will not connect the REMOTE CONTROL connectors of
this unit and the power amplifier, do not connect the cable to
either connector.
