OPERATION

Before turning on the Enterprise, ensure that all precautions and warnings have been carefully reviewed and adhered
to. Damage to the Enterprise 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 Enterprise

With the Enterprises' rear panel main power switch turned off, connect the signal outputs of the preamp/processor to
either the single-ended or balanced input of the Enterprise. Connect the output to the input of the speaker that is
intended to be driven. Please refer to figure 5.
If the Enterprise has a second binding post output connector, this is to be connected to the second speaker input
terminal.
Please Note: The Enterprise 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 Enterprise does NOT have
internal circuitry with a common ground.
Connect a 12V pulse trigger source to the STANDBY trigger input of the Enterprise, if it is desired to be taken in and
out of standby via another device.
If the Enterprise's functionality is to be controlled from a remote controller via RS232, connect the RS232 cable
between the Enterprise and the controller, using either the DB9 or RJ45 RS232 connector on the Enterprise.

Setup and Operation

Turn the output volume of the preamp/processor, or other source device, down all of the way.
Turn on the MAIN POWER switch, located on the rear panel.
When first turning on the rear panel power switch, the red STANDBY LED on the front panel will illuminate, indicating
that the Enterprise is in standby mode. When in standby, the signal is muted and the output bias of the Enterprise is
reduced to approximately 10 percent.
Press the round standby button on the front panel to take the Enterprise out of standby. The STANDBY LED will turn
from red to green.
Slowly bring the output volume of the preamp/processor up to an audible level.

Remote Triggers

When the rear panel STANDBY trigger jack receives a 5-12 VDC pulse, the Enterprise will change its state from either
standby to operate, or operate to standby, depending on what the current state is.

RS232

RS232 is another option in the Enterprise. It can be installed at any time either at the factory or by an authorized
Theta dealer. All functions of the Enterprise can be controlled and monitored via RS232, using either the RJ45 or DB9
connector. As long as the rear panel MAIN POWER switch is turned on, the RS232 circuitry is always active, thus
allowing the Enterprise to be taken out of STANDBY via RS232.
