QSC E112 overview

  • 1Description

The QSC E12 / E18SW System combines two E112 12" two-way loudspeakers with two E118SW 18" subwoofers and a PLD4.3 processing amplifier to create a turnkey sound reinforcement solution for clubs, bars, houses of worship, touring bands, and mobile DJs.

  • 2 x QSC E112 12" Two-Way Passive Loudspeaker (Black)

    The black QSC E112 is a trapezoidal, two-way loudspeaker, well suited for sound reinforcement applications including live performance, DJ and dance music, karaoke, and event production. The E112 requires an amplifier with a minimum of 400W continuous (1600W peak) to power the 12" woofer and 1" compression driver that combine to offer a frequency response of 64 Hz to 20 kHz (-6 dB) with a peak SPL of 128 dB. QSC recommends the use of a DSP 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 85°, which is suitable for most medium and medium-to-long-throw applications. 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 400W continuous (1600W 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 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
    UPC: 684284076601
  • 2 x QSC E118SW E-Series 18" Passive Subwoofer (Black)

    The black QSC E118SW Passive Subwoofer is a high-performance direct radiation subwoofer, well suited for sound reinforcement applications including live performance, DJ and dance music, karaoke, and event production. The E118SW requires an amplifier with a minimum of 800W continuous (3200W peak) to power the 18" woofer, which offers a frequency response of 37 to 230 Hz (-6 dB) with a peak SPL 133 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, stage monitoring, dance music, and karaoke.

    The rugged plywood enclosure is coated in black textured paint and features a heavy-duty grille lined with foam for protection. A threaded, M20 pole socket and speaker pole are provided for sub/satellite use with any of the E-Series two-way full-range loudspeakers. For portable applications, the E118SW includes attachment points for four optional casters.

  • QSC PLD4.3 Processing Amplifier

    The QSC PLD4.3 Processing Amplifier from PLD Series is designed specifically for the needs of portable and production sound system users. It provides efficient, robust, and high-fidelity power to drive multiple channels and configurations of loudspeakers while simultaneously deploying sophisticated digital processing with minimal operator complexity. This powerful and lightweight 4-channel amplifier with onboard, advanced DSP has the capability to configure and combine channels in various ways to drive a wide range of loudspeaker systems.

    The PLD4.3 Processing Amplifier features Flexible Amplifier Summing Technology (FAST) that actively distributes the total amplifier power in various combinations across 1, 2, 3, or all 4 outputs. This flexibility allows PLD Series amplifiers to drive (for example) 4 full-range loudspeakers or subwoofers; a high-power subwoofer and a bi-amplified speaker; a single high-power full-range loudspeaker and subwoofer combo; or multiple power-hungry subwoofers from a single, very high output mono-block.

    This amplifier uses QSC fourth generation class-D power amp design in combination with a custom power stage utilizing a purpose-built output device. This MOSFET device provides high voltage operation without needing a full bridge output and offers good audio quality due to co-location of the semiconductors. Additionally, it benefits from the PowerLight power supply, further enhanced with PFC (Power Factor Correction) that aligns the current waveform with the AC mains voltage waveform. PFC enables this amplifier to draw current from the wall in an efficient and controlled manner resulting in power from a single standard AC breaker. Additionally, it offers multi-stage sleep modes, saving energy when possible without ever sacrificing performance. The result is a powerful and flexible platform that offers low weight and efficiency.

    The PLD4.3 Processing Amplifier also doubles as a loudspeaker processor. The close integration of processing and amplification allows the DSP to monitor and respond to amplifier behavior, making dynamics processing accurate and effective. This synergistic approach employs both RMS and Peak Limiters that allow the combination of amplifier and loudspeaker to produce more output without being pushed to distortion or destruction.

    In addition to the dynamics processing, the onboard DSP offers 4 channels of crossover filters, parametric EQ, and alignment delay - everything needed to optimize a loudspeaker system. The amplifier also offers Intrinsic Correction, a combination of IIR and FIR Filtering and loudspeaker processing methodology. Intrinsic Correction compensates for the non-linearities in loudspeaker array and horn design and results in good performance from your QSC loudspeakers (sold separately).

    The on-board processing is managed and stored as presets, with 20 factory presets for the most common loudspeaker applications. For great customization, the built-in Preset Wizard streamlines amplifier setup and provides loudspeaker selection of passive loudspeakers (sold separately).

    With 4 channels of amplification plus drive rack signal processing in just 2RU, this amplifier replaces equipment taking up as much as 3 times the rack space.

    With a dedicated front panel UI complete with LED meters and indicators, a 400 x 240 TFT color display, a rotary encoder and ergonomic navigation buttons, this amplifier provides an intuitive interface for the user to control the system. The complete system can be set up in mere minutes.

    FAST (Flexible Amplifier Summing Technology) drives most any loudspeaker system or configuration by distributing total amplifier power across 1, 2, 3, or all 4 channels
    4 channels of full function onboard loudspeaker DSP with crossover and parametric EQ filters, limiting and alignment delay eliminate the need for outboard loudspeaker processors
    Powerful Intrinsic Correction processing maximizes the sonic performance of QSC loudspeakers
    20 factory preset configurations that can be modified and stored in the 50 user presets
    PowerLight universal switch mode power supply with PFC for efficiency, good audio performance, and low weight
    4 input XLR connectors, and 6 NL-4 output connectors
    Integrated front panel with channel select and mute buttons, input and output LED metering, 400 x 240 LCD, intuitive navigation buttons, LED power button and indicator, and cast aluminum handles
    Preset Wizard simplifies amplifier configuration providing loudspeaker selection from a list of passive speakers
