with only a single cycle of a
2,000Hz tone burst.
Power Guard
During normal operation,
the Front Panel Power Guard
Indicators will momentarily
illuminate during peaks in the
audio signals. In the event the

activate. The Front Panel Power
Guard Indicators will continu-
ously illuminate and the audio will be muted. When the
MA7000 has returned to a safe operating temperature,
normal operation will resume.
