QSC K Series Heritage
Portable Professional Performance
The KC12 BLK builds upon the legacy of QSC's World of K® series, offering a column aesthetic with acoustic performance superior to conventional designs. Simple and rapid deployment for professional applications.
High-Fidelity 3-Way System
12" Driver for Low Frequencies
The 12" woofer cone provides deep low frequencies down to 40Hz. The 12" size is ideal for portable systems that require powerful bass.
2x 4" Drivers for Mid-range Frequencies
The 2x high-excursion 4" cone drivers provide clear and powerful mid-range frequency reproduction. Dual drivers ensure uniform coverage.
1" Compression Driver for High Frequencies
The 1" compression driver provides clear and detailed high frequencies. The compression driver is ideal for long-distance coverage.
Proprietary QSC LEAF™ Waveguide
Length-Equalized Acoustic Flare
The QSC LEAF™ waveguide provides defined and uniform 145° horizontal x 35° vertical coverage. The LEAF waveguide ensures consistent frequency response.
Excellent Projection
The LEAF waveguide provides excellent sound projection. Projection is important for long-distance coverage.
3000W Peak Class D Amplifier
Efficient Power
The 3000W peak Class D amplifier (2000W subwoofer + 1000W mid/highs) provides efficient power with low energy consumption. The Class D amplifier is modern technology.
Power Factor Correction
Power factor correction reduces AC energy consumption. Power factor correction is important for portable applications.
Flat Frequency Response
45Hz - 18.5kHz at -6dB
The frequency response of 45-18.5kHz at -6dB provides flat reproduction in the audio band. Flat response is essential for accurate reproduction.
Extension to 40-20kHz at -10dB
The extension to 40-20kHz at -10dB provides bass and high-frequency extension. Extension is important for full-range reproduction.
132dB Maximum SPL
Powerful Sound Pressure
The 132dB maximum SPL measured on-axis at 1m provides very powerful sound pressure. 132dB SPL is sufficient for most professional applications.
Advanced Bluetooth Connectivity
True Wireless Stereo (TWS)
Bluetooth TWS ensures low-latency pairing between the music source and both left/right speakers simultaneously. TWS is ideal for wireless stereo.
QSC Loudspeaker Control App
The app allows control of the KC12, CB10, and all Bluetooth-equipped QSC speakers from a phone. The app provides access to essential controls and advanced capabilities.
Advanced Digital Controls
Multifunction LCD Screen
The 45 x 25.4mm LCD screen allows control and selection of speaker functions including global parametric EQ, subwoofer level, presets and scenes, Bluetooth configuration, delay (200ms), and reverb.
Assignable Presets
Independent assignable factory presets for each input are perfect for small events where two microphones are needed for different uses.
Professional Inputs
2x XLR Combo Inputs
The 2x XLR combo inputs include Mic/Line/Hi-Z and Mic/Line/+48V. Combo inputs allow for flexible connection of microphones and line sources.
3.5mm Stereo Input
The 3.5mm stereo input allows for connection of portable devices. The 3.5mm input is ideal for phones and tablets.
XLR Outputs
XLR outputs include loop-thru and post-DSP mix output. The outputs allow for connection to additional systems.
Portable Modular Design
Modular Components
The system includes KC12T (145° dual 4" column unit), KC-SP32 (32" column pole), KC12S (12" 3kW column subwoofer). Modular components allow for flexible configuration.
Flexible Deployment
Configured with or without the column pole, the system is ideal for direct deployment on the floor, stage, or riser. The flexibility allows for adaptation to any space.
Adjustable Height
Tall deployment: 2270mm (89.4") with KC-SP32. Short deployment: 1463mm (57.6") without KC-SP32. Adjustable height allows for coverage optimization.
Rugged Construction
Impact-Resistant ABS Enclosure
The ABS enclosure provides impact resistance and durability. ABS is resistant to environmental conditions.
Birch Plywood
The 12mm birch plywood provides a rigid structure. Plywood is durable and lightweight.
Powder-Coated Aluminum
The powder-coated aluminum provides a professional finish and corrosion resistance. Powder coating is durable.
