Product description

• QSC KW181 1000W 18" Active Subwoofer 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.

  • XLR/TRS combo inputs accept mic and line level signals. Direct XLR line outputs are provided for each channel
  • Intrinsic Correction maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target, for excellent performance across the entire sound field
  • DEEP technology and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies
  • GuardRail protection technology protects both the amplifier module and your performance from unnatural and destructive clipping
  • Multiple EQ modes let you optimize the sub's output for specific applications with the flip of a switch
  • The onboard LED indicator can be set to illuminate when power is on, to only illuminate when the clip limiter circuit is engaged, or to always be off

• Kopul Premium Performance 3000 Series XLR M to XLR F Microphone Cable - 20' (6.1 m), Black 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
  • Neutrik XX silver connectors offer high conductivity
  • Caged type contact and improved ground contact
