Nº500H Series Power Ampliﬁer

If this case occurs, consider installing a dedicated AC circuit for the

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.

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 the N

500H series

power ampliﬁer is capable of using. Contact a local, licensed

electrician for further information.

The Nº500H series power ampliﬁer is designed for continuous

operation and has three operating states:

• Off – AC power is disconnected using the rear-panel Power

switch or by removing the power cord from the rear panel.

• Standby – this is an energy-saving mode. AC power is only

connected to the low-voltage power supply, so all nonaudio

functions, such as ML Net and triggers, are active.

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

The ampliﬁer 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 power ampliﬁer, make sure it is powered

off with the Power button. Then make sure the power cord is

disconnected from the rear panel connector and the electrical

outlet.

Caution!
