2x E115 15" Passive Loudspeakers, and a GXD8 Professional Power Amplifier
15" Two-Way Passive Loudspeaker (Black)
The E115 is a trapezoidal, two-way loudspeaker using a 15-inch, 500W, die cast aluminum frame woofer with a 3.5-inch voice coil. It is intended for use when high-power and authoritative low-end are needed from a full-range loudspeaker. A 2.8" compression driver attached to the 75° DMTTM waveguide assures that even distant listeners will be well covered.
E Series loudspeakers will perform very well with any quality, professional power amplifier - but by taking advantage of the complete E Series Entertainment System, more performance and options are available. Today's powered loudspeakers rely on finely tuned digital signal processing (DSP) to achieve a higher level of performance. When used with QSC GXD or PLD amplifiers or with a QSC TouchMix digital mixer, E Series loudspeakers can also take advantage of advanced DSP. QSC has developed E Series DSP settings for all three platforms. These settings support a variety of applications including live sound reinforcement (with and without subwoofers), stage monitoring, dance music and karaoke.
Professional 4500 Watt Peak 2-Channel Power Amplifier with DSP
The GXD8 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 GXD8 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 GXD8 ships with a standard IEC power cord.
