Installation Considerations

The Nº433 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.

•DO review “Important Safety Instructions” on page 2 and “Power Requirements” on page 9 before installing the Nº433.

•DO place the Nº433 on a solid, flat, level surface such as a table, shelf, or floor OR bolt the Nº433 into a rack-mounting system. Use a purpose-built rack-mounting system to accommodate the weight of the power amplifier. Refer to “Rack-Mounting” on page 33 for additional information.

•DO position the Nº433 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 six-inch (15cm) clearance behind the Nº433

for the power cord and signal cables to bend.

•DO refer to “Dimensions” on page 32 for assistance with custom installations.

•DO NOT position the Nº433 near low-level components. This power amplifier is capable of producing massive output currents, which could generate significant magnetic fields and induce noise in some sensitive components.

•DO NOT place the Nº433 on a windowsill or in another location in which it will be exposed to direct sunlight.

Before moving the Nº433, 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 Nº433 without adequate assistance. Proper lifting requires at least two people.

•DO select a dry, well-ventilated location out of direct sunlight.

•DO allow at least a two to three-inch (5 to 8cm) clearance above the Nº433 for proper heat dissipation through air circulation. The Nº433 is designed for passive, convection cooling.

•DO NOT obstruct the ventilation holes on the top and bottom of the Nº433 or reduce airflow through the Nº433.
