QSC KW122: 12" 2-Way Active Loudspeaker

Features:

• K-series performance in a lightweight, birch design
• 1000 W class-D power modules in all models (2 x 500 W continuous)
• Extensive DSP featuring deep and intrinsic correction enhances system performance
• DMT (directivity matched transition) ensures uniform coverage across the entire sound field
• Rugged, texture-painted birch enclosures
• 4 position mic / line gain (full-range models)
• Tour grade 16 gauge steel grilles
• Comfortable ergonomic handles
• 35 mm pole sockets through tilt-direct on KW122 and KW152, standard (non-tilt) pole socket on KW153
• M10 rigging points for suspended installation (full-range models)
• KW122 also functions as stage monitor

High output: 

Like K-series, each of the four KW-series models features a QSC designed, 1000 W (2 x 500) class-D power module.  And continuing in the K-series tradition, every model is fitted through the identical high output 1.8" HF device (full-range models) and woofers of the same high quality design, regardless of speaker size.

Defined coverage area: 

Directivity matched transition (DMT) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.

DSP: 

Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a product in this category.  Intrinsic correction, first featured in our high end line array products 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.  The result is a speaker that behaves equally well across the entire sound field.  Deep and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.  Guard rail protection, first introduced on our GX-series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.

Connectivity: 

KW-series features a 4 position mic / line gain switch that allows for connection of a wide variety of devices.  Combo XLR and 1 / 4" TRS inputs accept both mic and line level input while a set of RCA phono inputs (except KW181) allow additional connectivity to portable MP3 players, CD players and line-level mixers.  Up to three audio sources can be mixed internally and summed to a balanced output for "daisy-chaining" of multiple units.  Separate direct outputs are also provided on each channel for additional output flexibility.

Control: 

On-board switches provide preset EQ settings.  The HF setting (full-range models) can be set to vocal boost for additional presence in the critical mid-frequency area or flat for accurate reproduction of the incoming signal.  The LF switch can be set to "normal", "deep" for additional bass extension, or "exit sub" (full-range models) for use through an external subwoofer.  The rear panel LED switch can be set to "power", illuminating the front-mounted LED when the unit is powered on, "off" for applications where it is not desirable to illuminate the front LED, or "limit" which indicates to the system operator that the clip limiter circuit has been engaged during operation.

Tilt-direct: 

The KW122 and KW152 feature a unique tilt-direct pole cup mounting system.  A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired.

Remote gain: 

Remote gain control capability is offered via a potentiometer (not included) connected to the on-board phoenix-style connector.  In an installed application, multiple KW-series speakers can be "daisy-chained" for total gain control from a single remote pot.  Auto-standby mode is engaged after 5 minutes of inactivity.

Premium-grade materials: 

KW-series is designed to withstand the rigors of professional use.  Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, low-noise casters (KW181) and a highly protective steel grille provide for ease of transport and long term durability.  Integrated M10 suspension points allow for flown applications through a KW M10 KIT (sold separately) and a threaded pole receptacle (KW181) provides for a positive, wobble free connection to a threaded speaker pole (included).
