Nº53 Power Amplifier

If this case occurs, consider installing a dedicated AC circuit for the home theater system. Contact a licensed electrician for assistance. If more than one AC circuit is providing power to the system, contact a licensed electrician to ensure that all components are operating with the same solid, low-impedance ground reference.

Caution! Building regulations and electrical codes differ from location to location, making it impossible to anticipate the requirements of amplifier high-current AC circuits, such as those that the No53 is capable of using. Contact a local, licensed electrician for further information.

Operating States

Caution!

The Nº53 Reference power amplifier is designed for continuous operation and has four operating states:

•Off – AC power is disconnected using the rear panel Power switch or by removing the power cord from the rear panel.

•Power Save – AC power is connected to the low-voltage power supply, the communication circuits, and the control circuits. All nonaudio functions, such as ML Net, are active.

•Standby – AC power is fully connected to the amplifier but the outputs are muted.

7

•On – the Nº53 is fully powered and all outputs are active.

The Nº53 should be unplugged during lightning storms and extended periods of nonuse as a precaution against potentially damaging power surges through the line.

BEFORE moving the No53 Reference power amplifier, make sure it is powered off with the rear panel Power switch. Then make sure the power cord is disconnected from the rear panel connector and the electrical outlet.
