QSC K12 2-Way Powered Speaker

The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. For starters, each of the four models features an all new, Pat Quilter designed 1000 watt QSC Class D power module. Next, breaking from the traditional loudspeaker paradigm, every model is fitted with the identical 1.75" HF device (fullrange models) and woofers of the same high quality for unparalleled performance, regardless of speaker size.

Extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system's size and weight.

Premium-grade materials, advanced construction processes and multiple mounting and suspension options allow for a wide range of live and installed applications.

Combo XLR and 1/4" TRS inputs accept both Mic and Line Level input while a set of RCA phono inputs (except KSub) 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.

On-board switches provide preset EQ settings. The HF setting (fullrange 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 NORM, DEEP™ for additional bass extension, or EXT SUB (fullrange models) for use with 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.

Fullrange models are housed in rugged ABS enclosures with a professional appearance that is at home in any application. ABS is a far more robust material than conventional speaker plastics and offers an additional measure of sonic clarity due to its internal rigidity. Ergonomic aluminum handles and a highly protective steel grille complete the package for ease of transport and long term durability.

The K Series fullrange models 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. Integrated M10 suspension points allow for suspended applications with a K SERIES M10 KIT (sold separately) or Yoke bracket (sold separately).

The KSub is a dual-12" bandpass design, constructed of premium birch and includes high-quality, low-noise casters. The subwoofer features a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included).

Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K 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.

Loudspeaker Specifications

Type
This is the type of professional loudspeaker. Active loudspeakers have a built-in amplifier to power the speakers. Passive loudspeakers require an external amplifier to be properly powered.
Active
High Frequency Driver Size
This is the size of the high frequency driver. Common sizes include 1", 1-1/2" and 2".
1"
Low Frequency Driver Size
This is the size of the low frequency driver. Common sizes include 10", 12", and 15".
12" Driver
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
52 - 18,000 Hz
Maximum Sound Pressure Level SPL
This is the maximum Sound Pressure Level (SPL) of the professional loudspeaker. The higher the SPL rating, the louder the monitors are able to go.
131 dB
Dispersion
This is the horizontal and vertical audio dispersion of the professional loudspeaker. The dispersion is measured in degrees.
75° H x 75° V
