Note:

It is important that a 2 Ohm (600.1) or a 1 Ohm (1200.1)

minimum total speaker impedance load is observed! If an impedance
load of less than the above minimums is used, you will eventually
damage your amplifier and void your warranty.

RCA INPUTS AND OUTPUTS

CROSSOVER

All Diamond Audio 

D5

amplifiers employ one of the most flexible internal

crossover sections currently available in mobile audio. The 

D5

600.1 and 1200.1

feature fourth-order 24dB/octave lowpass and second-order 12dB/octave
subsonic Butterworth filters. These filter networks sum to a flat response at
their -3dB break points. This results in a smooth and seamless transition from
one frequency band to the next. Butterworth filters provide maximally flat
frequency responses when compared to other filter structures.

All crossover controls are mounted on the signal side of the amplifier. The 

D5

600.1 and 1200.1 crossovers are continuously variable, lowpass from 50Hz to
250Hz, and a subsonic from 15Hz to 40Hz. This creates a flexible bandpass
filter for any subwoofer system. The D5 600.1 and 1200.1 also feature a phase
switch that when pushed in swaps the amplifier 180 degrees out of phase.
This enables you to use one class D5 as a positive amp and a matching one as
a negative amp, doubling your power as one channel.
