CPD 1 Powered | C 1 Unpowered Top Boxes

The CPD 1 complements the KS Audio CPD Series of FIR CONTROL DSP active self-powered systems, with the unique directivity of HDSP technology. This results in the highest possible sound pressure level with extreme accuracy (even in the lower frequency ranges), while simultaneously having the lightest weight possible. The DSP controller works with KS Audio FIR filter technology for true impulse-correct reproduction of audio. There are two integrated amplifiers -- 400W for the 10” driver and 40W for the 1” tweeter -- with a peak performance of 800W.

The sound dispersion from the HDSP mid / high frequency horn and its electronic blending with the bass / midrange driver is truly very unique. The HDSP design results in multiple integrated dispersion angles that widen downwards towards the near field of the speaker while maintaining tight pattern control and long throw capability. The vertical bending of the HF wave front continues through the cut-off frequency as well as the crossover frequency, without any variance in the frequency response. This means that with a standard two speaker setup, the audience in close proximity to the speakers will enjoy the same audio quality and definition as those further away.

The electronics are comprised of a switch mode power supply with Power-Factor-Correction, a “cold” PWM amplifier for bass / midrange performance, and an analog FET amplifier with the best audio characteristics for the mid-high compression driver. Both the 10” long throw woofer and the 1” compression driver have strong--but light--neodymium magnets. The 1” compression driver works with a 3” ring membrane made of Mylar that has a distinctly reduced distortion factor when compared to a titanium membrane.

With the CPD 1, KS Audio has responded to the demanding needs of the professional live sound engineer with a universal self-powered loudspeaker that produces the highest audio quality in a compact size. There are many applications in which the CPD 1 can be used: theater, live stage music, in large rooms or tents, as a delay system for far away areas, or as a compact middle-high frequency system in combination with one of the many KS Audio subwoofers (we recommend the CPD B or the CPD W1 subwoofer).

The speaker cabinet construction, like all KS Audio systems, is built from birch plywood with an extremely robust charcoal colored polyurethane coating. At your request the finish available can be changed to any desired color from the RAL color charts. Further features of this high-quality product include a pole mount in the bottom of the cabinet, and a protective steel grill on the front, with or without acoustic foam.

The rear mounted 2-way DSP controller / amplifier operates very efficiently without the need of a cooling fan. The FIR crossover and filter are specially matched to the drivers, with corresponding compressors and limiters to ensure safe operation. The electronically balanced input is in the form of XLR connectors. In addition to the power switch, the control panel also has a selectable digital volume / delay control to individually adjust for each venue and offers a digital delay reaching up to 40 m (120ft) for decentralized PA systems.

The CPD 1 operates on AC 117V-230V electrical supply. The starting current is electronically limited. A PowerCON connector is fitted.

C 1: Same as CPD 1 but unpowered.
