Front Panel Features

Overview

Your Theater Grand Ampliﬁer has seven channels of power ampliﬁca- tion combined in one chassis for the purpose of reproducing music or video soundtracks. It accepts line level signals from a controlling preampliﬁer and ampliﬁes them to a higher level, suitable for driving powerful stereo and Home Theater speakers.

Power Switch

Press the power switch to turn the ampliﬁer on. With this switch pressed in, the “Standby/On” LED will turn red when the ampliﬁer is in standby, or blue when the ampliﬁer is on. The rear panel switch controls how the ampliﬁer turns on (signal sensing, 12V trigger, etc.). Please refer to page 8 for more details.
