Product description

• 2 x QSC KLA12 12" 2-Way Line Array Loudspeaker (Black)
  • KLA Introduction
  The KLA12 12" 2-Way Line Array Loudspeaker (Black) is a compact speaker designed to be used as part of a speaker array system. The speaker features a rugged ABS plastic enclosure that provides lasting durability in a lightweight package. The speaker has a 12" woofer and a 1.75" compression tweeter to provide crisp, detailed sound reproduction with a wide frequency response. An efficient 500W x 500W power amp module provides clear, strong audio. The efficient design allows up to 5 KLA models to be driven from a single 120VAC 15 amp electrical circuit.
  
  The speaker has QSC's DEEP DSP algorithm, which provides extended bass by actively managing low-frequency transients. GuardRail protection circuitry prevents the amplifier module from unnatural and destructive clipping. An auto-standby mode will auto-engage after 5 minutes of inactivity to save energy. XLR and PowerCon input and thru connectors provide connection versatility, while a Phoenix connector allows daisy-chaining.
  
  The speaker is expressly designed for use in fixed arcuate line arrays, and has a 12:1 design factor with a 90 x 18° coverage pattern, allowing up to 5 units to be configured for 90 x 90° coverage. Most other systems require 6 units for the same coverage pattern. The KLA12's SOLO (Single-Operator Logistics) Rigging System allows you to easily assemble and disassemble the line array in a short amount of time without special tools or external hardware.
  
  Ar-Q (Arcuate Equalization) processing enables you to quickly tune the array, making appropriate adjustments based on the number of boxes in your array. By simply using a dial, you can choose the total number of boxes for a balanced and accurate tonal curve. Proprietary Intrinsic Correction technology adjusts the time, frequency, and amplitude response for a flat bandpass target.
  
  Up to 2 loudspeakers can be mounted on a stand or over a sub for a ground stack, thanks to a threaded Tilt-Direct 35mm pole socket. The socket also allows you to aim the speaker 9° downward for the best audience coverage. M10 fittings in the top of the enclosure allow up to 5 units to be flown in a suspended rig. An optional array frame is also available separately for additional mounting options.

• QSC KW181 1000W 18" Active Subwoofer
  • KLA Introduction
  The KW181 from QSC is a professional-quality active 3-way PA loudspeaker. Ideal for low frequency reinforcement of KW-series loudspeakers, the lightweight and rugged birch cabinet houses an 18" woofer to deliver deep, thumping bass with frequencies as low as 35Hz. An efficient Class-D amplifier provides an output power of 1000W for strong audio with low distortion.
  
  The sub offers excellent connectivity, with XLR/TRS combo inputs that accept mic or line signals. Direct XLR line outputs are provided for each channel. Extensive internal DSP includes Intrinsic Correction, DEEP, and GuardRail technologies to provide terrific sonic clarity and component protection for reliable operation.
  
  Onboard control options allow you to adjust EQ to perfectly match your surroundings and applications. You can also use the rear-panel Phoenix connector to connect an external potentiometer (not included) for remote gain control. The sub has a standard 35mm pole socket and a threaded pole for securely mounting a loudspeaker on top of the subwoofer. It also has ergonomic cast-aluminum handles and low-noise casters for easy transport.

  • KLA Introduction
  The black Kopul Premium Performance 3000 Series XLR M to XLR F Microphone Cable (20') is designed to be an extremely quiet and flexible cable that is ideal for the most demanding live sound and performance applications. The cable is engineered to be durable and to provide protection against EMI, RFI, and static noise. While the cable's color-coding affords the ability to quickly differentiate between multiple connections on stage, it provides a pleasant aesthetic quality at the same time.
  
  Premium Performance 3000 Series cables are made from 24-AWG OFC copper wire that's wrapped with PE insulation and a conductive PVC inner shield. A cotton-yarn inner layer helps reduce electrostatic and microphonic noise. 95% dual-spiral shielding makes the cable resistant to EMI and RFI noise. The Neutrik XX silver connectors provide a high level of connectivity, and all the solder connections are shrink-wrapped for protection.
  • 95% dual-spiral shielding offers protection from EMI and RFI noise
  • Twin conductive PVC inner shielding provides 100% coverage of the core conductor. It helps keep the cable's signal from radiating and affecting nearby cables, and also helps prevent external EMI from penetrating to the cable's core
  • 24-AWG oxygen-free stranded copper inner core provides the best possible conductivity
  • Cotton yarn reduces electrostatic and microphonic noise
  • All solder points shrink-wrapped for protection
