Each of the five Equalizer Frequency Controls will raise or lower by approximately 12dB, the amplitude of the band of frequencies centered at the frequency marked above the controls. Both Left and Right Channels are affected. At the center detent or flat position of the controls, all equalizer circuit components are removed from the signal path.

Power Output Meters The MA7000 Power Output Meters indicate the power delivered to the Loudspeakers. The meters respond to all the musical information being pro- duced by the Amplifier. They indicate to an accuracy of at least 95% of the power output 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 MA7000 over heats, due to improper ventilation and/or high ambient temperature, the internal protection circuits will 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.
