More info

QSC GXD4 is a professional power amplifier that is designed to maximise QSC E Series loudspeakers with a high peak output power with up to 1600 Watts.

Its prominent feature is DSP or the Digital Signal Processing section that includes High and Low-Pass filters (24dB LR), 4-band parametric equaliser, signal alignment delay, and RMS/Peak speaker protection limiting. There are twenty presets for selected typical systems that provide generic “starting points”.

Also, GXD amplifiers come pre-loaded with QSC E Series loudspeaker tunings, enabling a simple connect and play system that maximizes
the performance of the system.

Also features an extensive and powerful loudspeaker processing built in that includes High & Low-Pass filters, 4-band PEQ, Limiting, and Delay.

Aside from the Digital Limiter that automatically protects the amplifier from damage due to temperature rise or overdrive. It also has a Class-D output stage with a universal power supply for high performance and efficiency.

Front panel LEDs indicate signal presence, input overload, and amplifier clipping. And, it also has adjustable speaker protection to match your loudspeaker’s power and impedance.

Its output features include a professional binding post and NL4 connectors (compatible with NL2) provide for mono and bi-amp speaker connections.

Meanwhile, its input features include parallel XLR and 1/4” TRS connectors for compatibility with any source while providing convenient loop-thru capability.

Furthermore, it also has a flexibility feature to create, store and recall up to 20-user presets for any application.
