QSC GXD 8 Overview

The GDX 8 from QSC is a professional power amplifier designed for professional PA systems utilizing speakers with 4 and 8 ohm loads and a maximum output of 4500W. The GDX 8 employs a class D output stage with a universal power supply for high performance and efficiency, while keeping the unit lightweight at 13.2 lbs. The integrated DSP section includes High and Low-Pass filters (24 dB LR), 4-band parametric equalizer, signal alignment delay, and RMS/Peak speaker protection limiting.

The parallel XLR and 1/4" TRS input connectors offer broad compatibility with convenient loop-through capabilities, while the professional binding posts and NL4 connector provide mono and bi-amped speaker connections. In addition to the limiting offers on the inputs and outputs, the GDX employs smart speaker protection by providing settings for the loudspeaker's continuous output and impedance (4 ohm or 8 ohm). The GDX 8 ships with a standard IEC power cord.

  • Power levels matched to popular loudspeakers and optimized for maximum headroom into 4-ohm and 8-ohm speaker systems
  • Class-D output stage with a universal power supply for high performance and efficiency
  • Extensive built-in loudspeaker processing, includes high & low-pass filters, 4-band PEQ, limiting, and delay
  • Large LCD display simplifies amplifier setup and indicates amp status
  • Inputs: Parallel XLR and 1/4” TRS connectors for compatibility with any source while providing convenient loop-thru capability
  • Precision rotary encoders for gain and DSP parameter control
  • Outputs: Professional binding post and NL4 connectors (compatible with NL2) provide for mono and bi-amp speaker connections
  • Digital Limiting automatically protects the amplifier from damage due to temperature rise or overdrive
  • Adjustable speaker protection to match your loudspeaker’s power and impedance
  • Front panel LEDs indicate signal presence, input overload, and amplifier clipping

question

How can I connect 6 speakers to a 2 channel amp?
Asked by: Anonymous
Depending on the specifications of your speakers it may not be possible to connect 6 speakers to a 2 channel amplifier. This particular amp is not designed to accept less than a 4 ohm load per channel. For information or suggestions on connecting speakers to this amplifier, please contact a Pro Audio Representative here by phone at 800-606-6969 or email [email protected]&lt;a href= http://bandh.com target= _blank &gt;bandh.com&lt;/a&gt;

question

CAN i connect 4 speakers 8Ohm 150w rms to each channel in parallel mode ?if not which is the best way to connect 4 speakers/channel, not to overload the machine or burn the speakers?
Asked by: iraklis i.
Connecting four 8 ohm speakers to a channel will present a 2 ohm load which the GXD 8 is not designed to handle. A minimum of 4 ohms per channel for proper operation is recommended by the manufacturer.
