Power Amplifier - 2 x 1900 Watt with DSP

The QX4500 captures all the key elements of Quest Engineering’s advanced amplifier designs and marries it perfectly with onboard 64-bit digital processing to produce an advanced power amplifier/DSP management system suitable for all professional applications.

With an amplifier section boasting 1900 Watts of pure sonic power per channel at 4 Ohms, low standby mains consumption, the QX4500’s rugged construction and stylish design allow it to be a brut of workhorse when it comes to power output, yet the sophistication of its on-board DSP give a depth of control that meets the highest of engineering standards.

The integrated DSP also features 10 parametric equalizers (PEQs) on each input and each output. Up to 100 presets can be stored in the DSP for instant recall.
