D9 800.2

Bridging

The channels on the D9 800.2 are capable of being bridged to a 4ÊOhm mono output.
Creation of the mono channel is accomplished by using the channel 1 positive (+) output
connection of the amplifier for the speaker positive and the channel 2 negative (-) output
connection of the amplifier for the speaker negative.
Note: It is important that a 4 Ohm minimum total speaker impedance load is observed
when bridging the amp! If an impedance load of less than 4 Ohms is used, you will
eventually damage your amplifier and void your warranty.

The RCA cables from your source unit should be inserted here.

Gain

This control matches the output voltage of the source unit or processor to the amplifier
inputs. Rotating this control to the "MIN" mark (counterclockwise) configures the D9
800.2 amplifier to accept input voltages as high as 15V RMS with the +14 dB input
circuitry implemented (see +14 dB input selection).
Due to the D9's high signal input and low noise performance capabilities, the gain
structure should be professionally set to achieve maximum performance and lowest
distortion. This should be done with an oscilloscope, DMM, and test tone.
Diamond Audio recommends that an authorized Diamond retailer with the correct
equipment configures this setting. Or see Gain Setting Brief on page 16.
