WARNING

Do not use the supplied power cord for other devices.

Maintenance

To use this product for an extended period of time, we recommend that you maintain it regularly.

WARNING

• Check the power cord regularly to see if it is dusty. If so, wipe o the dust completely. Otherwise, re or electric shock might be
caused.

• Do not use aerosol or ammable gas spray for cleaning or lubrication. Otherwise, ammable gas will build up inside the unit,
causing possible explosion or re.

NOTICE

• Use a dry soft cloth to clean the unit. Using cleaning agents, such as benzene or thinner, detergent, or chemically-treated cloth
might cause color changes or deterioration of the surface. If the surface gets very dirty, damp a cloth with detergent (diluted
with water), wring the cloth tightly, and wipe o the dirt.

• If you wipe the surface area in the vicinity of the Yamaha logo with force, the logo might peel o or ber from the cloth might
stick to the surface.

Mirror-nish side panels

We recommend that you use a cleaning cloth such as those made for pianos. If the surface is very dirty, use a soft cloth
that is damp with water and wrung tightly.

Surfaces other than the mirror-nish side panels

Wipe other surfaces using a soft dry cloth. If the surface gets
very dirty, dampen a cloth with detergent diluted in water,
wring the cloth tightly, and then wipe the dirt from the surface.

NOTICE

Do not use balanced and unbalanced connections between
two components simultaneously. Doing so would create a
ground loop that could generate static and noise.

Balanced connection

A balanced connection is a great advantage against
external noise. For a balanced connection, use a cable
with male XLR connectors. When connecting a cable, be
sure to align the pins on the connector with the holes on
the jack, and then insert the connector into the jack until
you hear a click. To remove the cable, while pressing
and holding down the lever on the BAL jack, pull out the
male XLR connector from the jack.

Connecting speaker cables

Using standard speaker cables

Remove approximately 10 mm (0.4 in) of

insulation from the end of each speaker
cable, and twist the exposed wires
together tightly to prevent short circuits.

CAUTION

• Do not loosen the knob excessively. Otherwise, the knob
might come o and a child might swallow it accidentally.

• To reduce the risk of electric shock, do not touch the
SPEAKERS terminals while the power to the unit is on.

NOTICE

If the SPEAKERS terminals come into contact with a metallic
rack, a short circuit might occur, resulting in damage to this
unit. When installing the unit in a rack, maintain a sucient
clearance to prevent the SPEAKERS terminals from coming
into contact with the rack.

To bi-wire your speakers, separate cables are used to
connect the mid/high-frequency speaker driver (tweeter)
and the low-frequency driver (woofer) on each bi-

wireable speaker to the amplier. Running separate
cables from the amplier can have a profound impact on
relieving the tweeter circuit from the back ush of EMF

(electromotive force) generated by the woofer’s voice
coil, resulting in less interference between HF and LF
ranges and better sound quality.

You need to use speakers that feature two sets of
terminals (total of four) that allow each speaker to be split
into two sections (low-frequency and mid/high-frequency
ranges).

To congure a bi-amp stereo system, you need two

M-5000 units.

The M-5000 features two built-in ampliers. Each of

these amps is connected to the mid/high-frequency
speaker driver (tweeter) and the low-frequency driver
(woofer) on the speaker of the corresponding channel.
You need to use speakers that feature two sets of
terminals (total of four) that allow each speaker to be split
into two sections (low-frequency and mid/high-frequency

ranges). Bi-amping speakers can prevent the back ush of

EMF (electromotive force) generated by the woofer from
affecting the signal, resulting in improved sound quality
in some cases.

Connect the input source to the L-channel input jacks on
both M-5000 units.
