Theta Digital Intrepid - Manual (Page 12)

OPERATION
Before turning on the Intrepid, ensure that all precautions and warnings have been carefully reviewed and
adhered to. Damage to the Intrepid caused by improper operation, wiring and/or ventilation will not be
covered under warranty and Theta will not be liable for any consequential damage or loss.
Connecting the Intrepid
With the Intrepid’s rear panel main power switch turned off, connect the signal outputs of each
preamp/processor channel to either the single-ended or balanced input of the Intrepid. Connect each
channel output to the input of the speaker that is intended to be driven. Please refer to figure 4.
Please Note: Each channel is a balanced bridge amplifier, thus the negative speaker terminal is NOT a
ground, and cannot be connected to a ground or a loudspeaker system with a common ground. Consult
your speaker manufacturer to ensure that any speaker in your system that will be connected to the Intrepid
does NOT have internal circuitry with a common ground.
Connect a 12V pulse trigger source to the trigger input of the Intrepid, if it is desired to be taken in and out of
standby via another device.
If the Intrepid’s functionality is to be controlled from a remote controller via RS232, connect the RS232 cable
between the Intrepid and the controller.
When first turning on the rear panel power switch, the red STANDBY LED on the front panel will illuminate,
indicating that all channels are in standby mode. When in standby, the signal is muted and the output bias of
each channel is reduced to approximately 40 percent.
Remote Trigger
When the rear panel STANDBY TRIGGER jack receives a 5-12 VDC pulse, the Intrepid will change its state
from either standby to operate, or operate to standby, depending on what the current state is.
RS232
RS232 is an option in the Intrepid. It can be installed at any time either at the factory or by an authorized
Theta dealer. All functions of the Intrepid can be controlled and monitored via RS232, using either the RJ45
or DB9 connector. As long as the rear panel power switch in turned on, the RS232 circuitry is always active,
thus allowing the Intrepid to be taken out of STANDBY via RS232.
