QSC E115 Overview

The QSC E15 System combines two E115 15" two-way loudspeakers with a GDX 8 processing amplifier to create a turnkey sound reinforcement solution for clubs, bars, houses of worship, karaoke, and live bands.

QSC E115 15" Two-Way Passive Loudspeaker (Black)

The black QSC E115 is a trapezoidal, two-way loudspeaker, well suited for sound reinforcement applications including live performance, DJ and dance music, karaoke, and event production. The E115 requires an amplifier with a minimum of 500W continuous (2000W peak) to power the 15.0" woofer and 1.5" compression driver that combine to offer a frequency response of 55 Hz to 20 kHz (-6 dB) with a peak SPL 130 dB. QSC recommends the use of a speaker processor or a power amplifier with integrated DSP in order to set crossovers, limiting, and equalization to ensure the best performance. QSC's GXD or PLD amplifiers, as well as TouchMix digital mixers offer on-board DSP and factory-tuned presets, which provide settings for live sound reinforcement (with and without subwoofers), stage monitoring, dance music, and karaoke.

The 15mm, 11-ply enclosure provides a direct-match-transition (DMT) coverage angle of 75°, assuring that even distant listeners will be well covered. An all-metal, dual-angle, 35mm socket allows the loudspeaker to be mounted vertically on a pole or angled down by 10° to improve audience coverage, and reduce rear wall reflections. Multiple mounting options using E Series Yoke or M8 eyebolts (sold separately) are supported. Input connections include dual NL4 as well as screw terminal receptacles.

  • High-output, professional-quality sound with 500W continuous (2000W peak) power handling
  • E-Series Entertainment System: advanced digital signal processing tunings and options using QSC GXD, PLD amplifiers or TouchMix digital mixers
  • E-Series Entertainment System DSP tunings are now available for PLD and GXD processing amplifiers.
  • Rugged tour-grade textured paint
  • Foam-lined perforated steel grille
  • Dual-angle pole socket
  • Optional accessories include:
    • Transport covers
    • M10 eyebolt kit

QSC GXD 8 Professional 4500W Power Amplifier with DSP

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.

  • High peak output power with up to 4500W
  • 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
