Specifications
Continious output power (RMS) Measured @ 14.4 V THD < 0.5%

4 Ohm bridge: 300 W x 2
Description of Specifications
Stable impedance load of the Quattro is 2 Ohm stereo & 4 Ohm bridged.
Operation below minimum impedance will stress the amplifier & void the warranty.
Excessive heat will also appear at a faster rate and the and the amplifier will go into thermal protection.
Protection can also be caused by the following
* Speaker overload
* Short circuit
* Input Voltage - RCA & Power Supply
The PCB is a Class H design, optimizing efficiency, limiting dimensions & improving performance superior to
Class A/B with the same scale. (Don’t mistake it for a Class D which has less audible qualities compared to Class H).
The optional wired remote only affects CH 3 & 4.
Operational voltage: 10 V ~ 15.5 V.
Operational voltage will also be affected by the load of the amplifier.
