D3 400.2
Bridging
The channels on the D3 400.2 amp are capable of being bridged to a 4 Ohm mono output.
Creation of the mono channel is accomplished by using the left channel positive (+)
output connection of the amplifier for the speaker positive and the right channel 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.
RCA
INPUT
The RCA cables from your source unit should be inserted here.
OUTPUT
These RCA outputs are used to provide unfiltered signal to an processor or another
amplifier.
Crossovers
The Diamond D3 400.2 amplifier features a second-order 12dB/octave electronic
crossover that is selectable for highpass or lowpass modes. These filters are then
adjustable between 55 and 550 Hz.
