2. 12 VDC Trigger Input
Although the AUTO-ON signal
sensing turn-on is adequate for most
installations, the 12 VDC trigger inputs
are offered as an optional way to turn

The Sunfire Theater Grand II, III, IV
TGP-5,and TGP-401 Processors have
a compatible 12 VDC trigger output

1/8" mono mini jacks are provided
for ease of installation, along with a
terminal strip to allow more flexibility
for custom-wired installations. The
terminal strip and both mini jacks are
internally connected in parallel, allow-
ing 'daisy chaining' to turn on multiple

The supplied 1/8" mini-plug mono
cable can be used to connect the
trigger output of the Theater Grand
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
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
seven 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-
either one can be connected to the

The second RCA input can be used
as a daisy-chaining output, sending
the preamplifier output signal to an-
other channel or to another amplifier.
