Designed for live sound and dance music, the Stereo Loudspeaker & Subwoofer System from QSC offers a complete solution ideal for venues of small to medium sizes. The system includes two E12 12" Passive Loudspeakers, two E18SW 18" 800W Passive Subwoofers, and one PLD4.3 Processing Amplifier.
The black E12 Loudspeaker is a trapezoidal, two-way unit that uses a 12”, diecast aluminum woofer with a 3” voice-coil. The 15mm, 11-ply enclosure provides enough volume to deliver solid low-frequency extension down to 50 Hz, making it ideal for applications in which space precludes the use of a subwoofer.
The black E18SW Passive Subwoofer is a high-performance direct radiation subwoofer with a single 18” aluminum frame 800W woofer. It is designed to produce low-end for live performances with kick-drum and bass in the PA or for high-level, high-energy dance music.
The PLD4.3 Processing Amplifier 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.
The black E12 12” Two-Way Passive Loudspeaker from QSC is a trapezoidal, two-way loudspeaker that uses a 12”, die cast aluminum woofer with a 3” voice-coil. The 15mm, 11-ply enclosure provides enough volume to deliver solid low-frequency extension down to 50 Hz, making it ideal for applications in which space precludes the use of a subwoofer. The DMT coverage angle of 85° 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.
The black E-Series 18” 800W Passive Subwoofer from QSC is a high-performance direct radiation subwoofer with a single, 18” aluminum frame 800W woofer. It is designed to produce low-end for live performances with kick-drum and bass in the PA or for high-level, high-energy dance music. A threaded, M20 pole socket is provided for sub/satellite use with any of the E-Series two-way loudspeakers (sold separately). For portable applications, it includes attachment points for four optional casters. The subwoofer’s 4-ohm impedance means that a single woofer can be optimally powered by a low-profile amplifier.
The E-Series Loudspeaker supports advanced DSP when used with the QSC GXD or PLD Amplifiers or with a QSC TouchMix Digital Mixer. E-Series Subwooder’s DSP settings allow it to be used for a variety of applications including live sound reinforcement, stage monitoring, dance music, and karaoke.
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.
