Amplifier Precautions
Before using the power amplifier M-5000R, be sure to
read the page above entitled Important Safety Instructions
and this page of Amplifier Precautions.
While using the M-5000R, the internal temperature will
fairly rise. Excessive temperature rise may affect the
amplifier performance. To prevent damage from occurring
due to high internal temperatures, it is vital to have proper
ventilation and passage of air to carry out the heat and
keep the internal temperature within acceptable ranges.
Caution
• Do not place the M-5000R inside cabinets or closets
where there is poor passage of air and ventilation.
• Do not place the M-5000R near external heat sources
such as heaters or hot air ducts.
• Do not place other components or object on top of or
under the M-5000R.
• The cover of the M-5000R contains ventilation holes to
allow the passage of air. Do not cover or block these
holes in any way.
If you are planning to place it within a cabinet, either open
holes in the rear panel of the cabinet to improve
ventilation or use a fan to force air circulation.
As a general rule, if during idling the cover is too hot to
touch, then ventilation needs to be improved.
Make sure that the floor or cabinet or rack where it will be
located is strong enough to support its weight.
You will also need to leave enough space behind the
M-5000R to allow room for the power cord and other
cables for connecting system components. A minimum of
10 cm (4") is required behind the M-5000R to allow room
for the cables and cords without excessively bending
them.
Do not place the M-5000R near TV or radio. This may
cause noise or instable video on radio or TV respectively.
Do not use a power cord other than the one supplied with
the M-5000R. The power cord supplied is designed for use
with the M-5000R and should not be used with any other
device.
Be sure to only use wall sockets that properly fit the plug
of the power cord. If the socket does not match the plug of
the power cord, you will need to prepare an adapter.
Always use an adapter that is properly certified for this
application.
Connected speakers should have an impedance of 4 ohms
or greater.
If speakers with an impedance of less than 4 ohms are
connected to RCA jacks, it may damage the M-5000R.
If a speaker with an impedance of less than 6 ohms are
connected to an XLR jack, it may damage the M-5000R.
Read the instructions supplied with your speakers.
Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive (+)
terminals, and negative (–) terminals only to negative (–)
terminals. If you get them the wrong way around, the
sound will be out of phase and will sound unnatural.
Unnecessarily long, or very thin speaker cables may affect
the sound quality and should be avoided.
Be careful not to short the positive and negative wires.
Doing so may damage the amplifier.
Make sure the metal core of the wire does not have contact
with the power amplifier’s rear panel. Doing so may
damage the power amplifier.
Don’t connect more than one cable to each speaker
terminal. Doing so may damage the power amplifier.
Don’t connect one speaker to several terminals.
(North American models)
If you are using banana plugs, tighten the speaker terminal
before inserting the banana plug.
Do not insert the speaker code directly into the center hole
of the speaker terminal.
