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.

Ventilation

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.

Installation location and space

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.

Power cord

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.

Speakers

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.
