INSTALLATION PRECAUTIONS

TRANSPORTATION

WARNING - To reduce the risk of fire or electrical shock, do not expose the amplifier to rain or moisture.

CAUTION - For units factory-set at 115 volts AC match the wide blade of the power plug to the wide slot of the power outlet, to prevent electrical shock. Be sure the plug is completely inserted into the receptacle.

Turn off all the components in the system whenever connecting or disconnecting any audio signal wiring. Once all signal connections have been completed, turn down all the system’s main volume control before turning the system components on. Then increase the volume control setting carefully to avoid damage to the system components.

NOTES ON INSTALLATION LOCATION

Read and follow all the safety instructions on the first page of this manual. To prevent a fire or shock hazard, do not place the amplifier where it will be exposed to any water or moisture. If liquid accidentally gets into the amplifier, immediately unplug the AC power cord. Do not operate the amplifier again until it has been examined by a service technician.

The amplifier generates a moderate amount of heat, requiring ventilation. Do not obstruct the air outlet grilles on the top or bottom covers. There should be at least 3 inches (7.5 cm) of clearance above the amplifier and 1 inch (2.5 cm) to the sides. Do not place the amplifier in an enclosed area, such as in a bookcase or in a cabinet, unless it is very well ventilated. Be sure there is adequate room behind the amplifier for signal input and speaker output connections. If you want to locate the amplifier on a carpeted floor, place a board under it in order to prevent it from sinking into the carpet, blocking the air inlets on the bottom. Do not place the amplifier where it will be exposed to direct sun light for prolonged periods of time.

This unit may be installed on any sturdy, level surface.

]NOTES: The amplifier’s weight must always rest on its bottom feet. Never put the amp down on its rear panel, with its front panel facing up. Doing so risks damage to the input/output connectors.

The power transformer in the M25 generates a magnetic hum field of moderate strength. Turntables (especially those with a moving- coil pickup cartridge) should not be located near the amplifier. Magnetic media, such as audio or video tapes and computer diskettes, should not be stored near the amplifier.

Transport - Transport the amplifier in both inner and outer shipping containers. Do not transport the apparatus using one shipping container; to do so may result in damage to either the apparatus or personnel.

SAVE ALL THE PACKAGING

Please save both boxes and all of the packaging in which your M25 arrived. Should you move or otherwise need to transport your amplifier, this is by far the safest set of containers in which to do so. We’ve seen too many otherwise perfect components damaged in transit for lack of proper shipping cartons, so please: Save both inner and outer boxes!

REAR PANEL CONNECTIONS/CONTROLS

1. IEC POWER SOCKET

Connect to the supplied IEC-standard removable AC power cord before connecting the AC power cord to the wall socket.

NOTE: Before connecting the AC-power cord to a live wall socket insure that all inputs/outputs are connected first. Always disconnect the AC power cord plug from the live wall socket first, before disconnecting any cable from the M25 amplifier. If you must use an extension cord, select a heavy-duty cord of the type used for large electrical appliances, such as an air conditioner AC-extension cord (16 AWG). We strongly recommend that you not connect the amplifier’s mains cable to the accessory AC outlets on a preamplifier. Such convenience outlets are not designed to supply the high-power levels that the NAD M-series amplifier requires.

2. INPUTS

Each of the seven independent power amplifiers within the M25 has its own signal input connector. Before making any connections to the amplifier, make sure the POWER is switched OFF. [See figure 1]

Connect the signal cables from the preamplifier, surround sound decoder, or other signal source to these inputs. For optimum heat dissipation in an AV surround system, we recommend you allocate the audio channels to the inputs as follows:

Channel 1 = Front Left speaker

Channel 2 = Surround Left speaker

Channel 3 = Surround Back Left speaker

Channel 4 = Center speaker

Channel 5 = Surround Back Right speaker

Channel 6 = Surround Right speaker

Channel 7 = Front Right speaker
