The Studiomaster QX4-8000 Digital Power Amplifier features advanced amplifier adjustment technology to give over 95% efficiency, and stable performance at high current, low impedance conditions.

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.

At 2ohm operation, the flagship QX4-8000 will supply up to 4 x 4760 watts, making these amplifiers supply extremely high performance, and provide cost-effective solutions for multiple install and rental applications, for example, line array systems.
