1. AUTO/ON/OFF Switch
Your Theater Grand Amplifier is designed with an automatic on/off circuit.
•In the
if it receives a 12 VDC input voltage at the trigger inputs. The amplifier will go to standby after a few seconds if the trig- ger voltage is removed, or after approximately 30 minutes in the absence of an audio signal.
•In the ON position, the ampli- fier is always on, regardless of input signals or 12 VDC trigger.
•In the OFF position, the ampli- fier is in standby, regardless of input signals or 12 VDC trigger.
•See page 7 for details of the front panel LED status.

Although the
The Sunfire Theater Grand II, III, IV and
1/8" mono mini jacks are provided for ease of installation, along with a terminal strip to allow more flexibility for
Any 1/8" miniplug mono or stereo interconnect cable will suffice to con- nect the trigger output of the Theater Grand Processor to the amplifier.
Do not exceed 18 VDC on this input. (CAUTION: Do not connect AC line voltage to this input!)

The voltage range for the trigger input is from 5 to 18 VDC. The input impedance is approximately 600 Ω (20 mA @ 12V).
3. RCA Inputs
Your Theater Grand Amplifier has
three sets of inputs for each of the five channels. Two are unbalanced RCA inputs and one is a balanced XLR type.
The two RCA inputs for each chan- nel are joined together internally, and either one can be connected to the corresponding output of your pream- plifier.
The second RCA input can be used as a
