The May PALM show QSC pushed active speaker
Date:2018-1-9
Last year the Frankfurt professional lighting and sound show the successful launch of K series active speaker, QSC continued to upgrade R & D, KW launched a series of wooden active speaker. The speaker continued series of portable K series active speaker of the core components of the acclaimed KW series, also by QSC engineers given force performance in a more perfect, with birch cabinet design upgrade. The speaker of new design compared with the wood box is more compact, lightweight.
KW series speakers as a new generation of wooden box loudspeaker, inheriting all the groundbreaking technology attribute K speaker series. As the second generation of products, the Baltic birch enclosure version of the KW series continues the distinctive technical features of K series, using 1000 Watt class D amplifier with the same (2 x 500 Watt), 1.75 inch compression unit (full frequency series) and DSP processing system, and QSC is used to optimize the whole system of patent technology.
KW series includes four models -- KW122 (12 inch 2 divider multipurpose box), KW152 (15 inch 2 frequency trapezoidal box), KW153 (15 inch 3 frequency trapezoidal box), KW181 (18 inch woofer unit).
This series adopts the new built-in DSP, compared with similar products, the series of speakers can provide higher levels of speech intelligibility and output sound pressure capacity. At the same time provides more DEEPTM and Intrinsic CorrectionTM advanced technology, bring about an order of magnitude performance improvement for audio. DMTTM (point to ensure that the unit conversion matching) speakers get consistent directivity in the coverage area. Intrinsic CorrectionTM (intrinsic correction) line array product technology was first applied in the high-end, the use 65-75 a laboratory measurement of mean value, and the use of IIR and FIR filtering, take the initiative to adjust the time, frequency and amplitude response, ensure the response straight in at high frequency, so each loudspeaker has a frequency and amplitude characteristics curve is flat in the entire sound field. In addition, KW series speakers also used Guard RailTM protection technology, the technology was first introduced in the GX series of power amplifier, power amplifier module output safety protection, and not by the sound characteristics of non natural signal or eliminate the impact wave distortion.
In a connection mode, the KW series provides rich terminal, meet the needs of different applications, including XLR, 1/4 inch TRS integrated input interface and RCA interface (KW181 speaker without this interface), at most three channel audio can be in after mixing with a loudspeaker inside road balanced output, and to "daisy chain cascade" will signal transmission to multiple speakers. Each channel is equipped with an auxiliary independent output channels, improve the flexibility of the loudspeaker signal distribution.
The KW series also provides several ways to control. A level Four microphone / line gain control knob, can gain convenient adjustment system. Connected to the speaker jack on the backplane of the Phoenix via an external potentiometer, the speaker also can realize remote gain control.
The box back control area offers a variety of EQ preset switch, for better performance in various frequency bands timbre. The three state LED lamp front panel can display the speaker: the power switch and the wave dissipation. If the speaker system in 5 minutes without any signal input, the system will automatically switch to energy-saving standby mode.
In the installation, KW series is unique. KW122 and KW152 speakers and unique with vertical angle of the supporting hole of the adjustable (Tilt-DirectTM) component, this component can be a downward adjustment of 7.5 degrees vertical angle, so that the sound energy projection listening area in the audience, away from the reflector, which is especially useful for placing the speaker position high. M10 hanging points can be matched with other accessories to achieve the speakers hanging installation. The top of the box with a screw hole for installing the pillar, can be directly inserted into the box supporting rod (included), with the installation of satellite speakers. The KW122 speakers can also be used as a stage monitor speakers.
KW series has ulterior motives in the body design and appearance, the box body adopts advanced birch wood, the surface is coated with wear-resistant coating, by strengthening the structure design, high intensity of the box body net cover, accord with aluminium handle of ergonomics, the bass sound box (KW181) with low noise casters, convenient transportation and handling protection, ensure to meet the harsh application and all kinds of special use.
In recent years, QSC companies continue to increase R & D efforts, frequently launch new products. K series launched last year made great market success, sales of similar products in the top ranked the United states. With the same "descent" KW series believe can continue to expand QSC in the active speaker Market influence.
