Installation Considerations

The Nº432/431 requires special care during installation to ensure

optimal performance. Pay particular attention to the precautions

included in this section and to other precautions included

throughout this owner’s manual.

Placement • DO review “Important Safety Instructions” and “Power

Requirements” before installing the Nº432/431.

• DO place the Nº432/431 on a solid, flat, level surface such as

a table, shelf, or floor OR bolt the Nº432/431 into a rack-

mounting system. Use a purpose-built rack-mounting system

to accommodate the weight of the power amplifier. Refer to

“Rack-Mounting” for additional information.

• DO position the Nº432/431 close to associated loudspeakers

to keep loudspeaker wires as short as possible. Use longer

interconnecting cables between the preamplifier and the

power amplifier. This is preferable because interconnecting

cables pass low-voltage signals, which transmit over distances

with greater accuracy than the high-voltage signals required

by loudspeakers.

• DO allow at least a 6-inch (15cm) clearance behind the

Nº432/431 for the power cord and signal cables to bend

without crimping or straining.

• DO refer to “Dimensions” for assistance with custom

installations.

• DO NOT position the Nº432/431 near low-level compo-

nents. These power amplifiers are capable of producing mas-

sive output currents, which could generate significant magnet-

ic fields that induce noise in some sensitive components.

• DO NOT place the Nº432/431 on a windowsill or in another

location in which it will be exposed to direct sunlight.

Caution! Before moving the Nº432/431, make sure it is powered off with

the front panel power button. Then, make sure the power cord

is disconnected from the ~ac mains connector and the electrical

outlet. Do not attempt to move the Nº432/431 without adequate

assistance. Proper lifting requires at least two people.
