Specifications (detailed)

2)  The amplifier has a 4 stage advanced protection circuit;

-Thermal protection, Voltage sensors, DC offset & short circuitry via speaker outputs.

The 

Quattro

 utilizes a double sided SMD pcb & high current mosfet switching devices in both 

the in- and output stage.

A

 4)    wired remote level control is optionally available the amplifier.

      - This unit will enable remote gain adjustment on channel 3 & 4.

 5) The crossovers are variable 18dB/Octave for both HP/LP & subsonic. 

      Band Pass is enabled by the use of the variable subsonic.

 6)  Operational voltage is 10V ~ 16V 

Specifications

Continious output power (RMS) Measured @ 14.4V THD < 0.05%

The 

Quattro 

operates stable @ impedances of minimum 2   stereo & 4   bridged.

Operation below minium impedance or improper use will void the warranty.
