Signal Input and Output Level Controls
The Orion 7005 amplifier has separate front, rear, and sub level gain adjustments. The input
sensitivity of these adjustments range from 200mV up to 5V. This allows easy integration
from any source unit. Refer to the Testing the System and the Adjusting the Sound of the
System sections for detailed instructions on setting up the level controls.
Four-Channel Amplifier Input Configuration
The 4CH / 2CH switch routes input from the front inputs to the rear section of the amplifi-
er. This allows the Orion 7005 channel amplifier to utilize a single set of RCA's to feed sig-
nal to the front and rear channels of the amplifier.
When the switch is to the right (2CH position), signal from the front inputs is routed to the
rear channels.When the switch is to the left (4CH position), front and rear inputs are inde-
pendent. This allows a source unit with an internal fader to fade between the front and rear
outputs.
IN / EXT Switch
The IN / EXT switch routes input to the subwoofer section of the amplifier. This allows the
Orion 7005 channel amplifier to utilize a single set of RCA's to feed signal to the subwoofer
channel of the amplifier.
When the switch is to the right (EXT position), the subwoofer channel is independent from
the other inputs. Signal from the subwoofer RCA inputs is routed to the subwoofer input.
This allows a source unit with a subwoofer out to control the subwoofer independently of
the other channels.
When the switch is to the left (IN position), the inputs from the front and rear channels are
summed together and routed to the subwoofer channel.
Internal Crossover Configuration
The crossover section of the Orion 7005 amplifier is continuously variable and extremely
flexible. The front, rear, and subwoofer channels are independently controlled. There are
different crossover configurations possible allowing high-pass, low-pass and band-pass con-
figurations. This circuit is designed to optimize the performance of all of the components
used in a high quality system.
