QX4-4000 4x1700 Watt Power Amplifier

The QX series of digital power amplifiers feature advanced amplifier adjustment technology to give over 95% efficiency, and stable performance at high current, low impedance conditions.

8ohms Stereo: 4x1000watts
4ohms Stereo: 4x1700watts
2ohms Stereo: 4x2890watts
16ohm Bridged: 2x2000watts
8ohm Bridged: 2x3400watts
4ohm Bridged: 2x5780watts

Additional features include active power factor correction (PFC) and ultra-reliable soft power switching power supply which will operate universally between 90-250VAC.

The QX series are all 1U height, lightweight designs, weighing less than 12kg. Both 2 and 4-channel versions are available, giving power ratings from 2550 watts per channel up to 5100 watts per channel at 4ohms.
