Specifications (detailed)
2) The amplifier has a 4 stage advanced protection circuit;
-Thermal protection, Voltage sensors, DC offset & short circuitry via speaker outputs.
The
Duo
utulizes a double sided SMD pcb & high current mosfet switching devices in both
the in- and output stage.
A
4) wired remote level control is included with the amplifier.
- This unit will enable remote gain adjustment.
5) The crossover of the
Duo
is a 18 dB/octave filter with an optional frequency multiplier of 10
for both high & low pass. The subsonic filter also has an 18 dB slope.
Specifications
Continious output power rating (RMS) - Measured @ 14.4 V
The
Duo
operates stable @ impedances of minimum 1 stereo & 2 mono.
- Running the
Duo
at these impedances sets requirements to ventilation & the battery system.
