MODE: NORMAL
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 biwireable speaker to the amplifier. Running separate
cables from the amplifier can have a profound impact on
relieving the tweeter circuit from the back flush 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).

MODE: DUAL MONO/BRIDGE
To configure a bi-amp stereo system, you need two
M-5000 units.
The M-5000 features two built-in amplifiers. 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 flush 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.

MODE: DUAL MONO/BRIDGE
In a bridge connection configuration, the M-5000 is used
as a monaural amplifier. To create a stereo system, you
need two M-5000 units.
On each amplifier, connect the “+” terminal of the
SPEAKERS L CH to the “−” terminal of the SPEAKERS
R CH. For this connection, use a cable that features the
same material as the speaker cables, and a length of 1.0 m
or less and a cross-sectional area of 1.0 mm2 or larger. Do
not bundle the cable.
Connect the input source to the L-channel input jacks on
both M-5000 units.
22
NOTICE
Since amplification will be doubled in this configuration,
adjust the volume level appropriately on the connected
preamplifier. If you are using a Yamaha preamplifier that
features a GAIN selector, adjust the volume level using this
selector so that you will be able to use volume controls on
other components in the usual way.

storms. Otherwise, an electric shock might be caused.
• Be sure to use a power outlet with the power voltage
labeled on the unit. If the unit is plugged into an outlet
of an inappropriate voltage, fire, electric shock, or
malfunction might be caused.
• Use only the supplied power cord. Do not use the
supplied power cord for other devices.
Otherwise, fire, burning, or malfunction might be caused.
• Plug the unit into an AC outlet that is clearly visible and
easily reached, so that you can unplug the unit easily and
quickly from the AC outlet in case of emergency.
Even when the power switch is turned off, a minimal
amount of electric current is still flowing to the unit,
unless you unplug the unit from the AC outlet.
• If a lightning storm is approaching, turn off the power
to the unit immediately, and disconnect the power plug
from the AC outlet.
Otherwise, fire or malfunction might be caused.
• If you plan not to use the unit for an extended period
of time, be sure to unplug the power cord from the AC
outlet.
Otherwise, fire or malfunction might be caused.

Remedy
See
page
The protection circuitry has
been activated because of a
short circuit, etc.
Make sure that the speaker wires are
not touching each other or shorting out
against the rear panel of the unit, and
then turn on the power to the unit.
16
The speakers are not connected
properly.
Make sure that the speakers are
connected properly. If the problem
persists, the cables might be defective.
16
There is a lack of bass
and no ambience.
The + and − wires are connected
in reverse at the amplifier or the
speakers.
Connect the speaker wires to the correct
+ and − polarity.
15
A “humming” noise is
heard.
Both balanced and unbalanced
cables are being used
simultaneously between two
components.
Do not use both balanced and
unbalanced cables simultaneously
between two components. Doing so
would create a ground loop that could
generate static and noise.
12
Problem
The sound is suddenly
muted.
