High output level:
As in the range K, each of the four models in the range KW has a class D power module 1,000 watts (2 x 500) designed by QSC, and in the tradition of the range K, is equipped with HF motors high efficiency 44 mm (range models) and woofers of such a high-quality design, regardless of their size.

Defined coverage area:
The DMTTM (Directivity Matched Transition) provides LF and HF cover attached on the entire listening area, eliminating frequency regions artificially "dead" or too herein.

DSP:
From one end to the other, extensive signal processing provides levels of sonic clarity and total output that exceeds all expectations for a product in this category:
• the Intrinsic CorrectionTM, appeared for the first time in our product line array of upscale, 65-75 applies to spatially averaged measurements IIR and FIR filters that actively adjust the time response, frequency and amplitude in order to obtain a bandpass optimal regularity. The result is a speaker that performs well across the entire sound field.

• DEEPTM and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.

• The GuardRailTM protection, introduced for the first time in our GX Series amplifiers protects both the amplifier module and your performance from all unnatural and destructive clipping.

Connectivity:
KW has a range selector gain mic / line four positions for connecting a wide variety of sources. Mixed XLR and 6.35mm 3 points (TRS) accept a mic or line level input while the RCA / phono inputs (except KW181) allow the additional connection of portable MP3 players, CD players and level mixers Online. Three audio sources can be mixed internally and summed to a balanced output for chaining "cascade" multiple units. Separate direct outputs are also provided on each channel for even more output flexibility.

Control:
Integrated switches allow correction presets (EQ). The HF setting (range models) can be set to VOCAL BOOST for additional presence in the critical midrange area or FLAT for accurate reproduction of the incoming signal. The LF switch can be set to NORM, DEEPTM for further extension in the bass or EXT SUB (full range models) for use with an external subwoofer. The LED on the rear panel switch can be set to POWER, making light of the LED front panel when the unit is powered on, OFF for applications where it is not desirable to see an LED on the front panel or LIMIT so that it informs the system operator any entry into service of the clip limiter circuit.

Tilt-DirectTM:
The KW122 and KW152 feature a mounting system mast base Tilt-DirectTM. A simple rotation of the wheel causes a tilt of 7.5 ° the enclosure, to maintain the acoustic energy on the audience and away from reflective surfaces in applications where you want maximum coverage from a high pregnant.

Remote Gain:
The ability to remotely gain control is offered via a potentiometer (not supplied) connected to the integrated Phoenix style connector. In a fixed installation, several speakers in the KW range can be chained "cascade" for total gain control from a single remote potentiometer. The automatic sleep mode is activated after 5 minutes of inactivity.

High quality materials:
KW range is designed to withstand the rigors of professional use. Sophisticated manufacturing process, the speakers in Baltic birch grade, molded ergonomic handles aluminum wheels with low noise (KW181) and a highly protective steel grille facilitate transport and ensure the long-term sustainability. Integrated M10 suspension points allow the suspended applications with a KWM10 kit (sold separately) and a threaded pole receptacle (KW181) provides stable mounting to a threaded speaker pole (included).
