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 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.

Bridged Power @ 4 Power @ 2 (1 stereo & 2 bridged operation requires optimal ventilation)
