QSC Unveils New Processing Amplifiers

qsc-processing-amp-1114QSC has announced the addition of GXD Series Processing Amplifiers to their line of amplifiers for entertainment and production applications. Featuring what QSC is calling “contemporary styling,” multiple routing options and advanced protection circuitry, GXD Series Amplifiers are housed in a 2U rack-mount configuration, feature class-D power output in a so-called lightweight chassis design. The GXD models offer a DSP that includes High and Low-Pass filters (24dB LR), 4-band parametric equalizer, signal alignment delay, and RMS/Peak speaker protection limiting. To allow users to get up and running quickly, 20 preset “starting points” for selected typical systems are provided. The GXD Amplifier’s digital limiter prevents destructive clipping which can damage loudspeaker components while still delivering the maximum usable output. Smart loudspeaker protection is set by selecting the loudspeaker’s continuous power and impedance (4Ω and 8Ω), and either a Mild, Medium or Aggressive protection mode as desired.

The GXD Series front panels include a power switch, four status indicators, and a large LCD screen that provides metering and status monitoring.  When combined with the two rotary encoders and three menu buttons the user is offered complete amplifier control allowing parameter selection and adjustment of amplifier gain and DSP parameters.  The rear panels include XLR and ¼” TRS inputs, NL4 and binding post outputs and the AC power inlet. With a solid 400-watts-per-channel at 8 ohms (600 watts-per-channel at 4 ohms), the GXD 4 provides a Max Total Peak Power of 1600 watts while the GXD 8 provides a robust 800 watts-per-channel at 8 ohms (1200 watts-per-channel at 4 ohms) with a Max Total Peak Power of 4500 watts.

The GXD 8 has a list price of $999.99 and the GXD 4 is $599.99 and both models will be available in January 2015 and complete specs are here.
