CPD 12 complements the KS AUDIO CPD-Series of DSP controlled active self-powered systems with the unique directivity of HDSP technology, resulting in the highest sound pressure level even in the lower frequency range 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 – 800W RMS for the 12”- low-mid speakerand 200W RMS for the 1.4” driver - with a peak performance of 2 KW!
The sound dispersion design of the HDSP HF horn and its electronic blending with the low-mid speaker is 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 LF performance, and an analog FET-amplifier with the best audio characteristics for the HF compression driver. Both the 12”- long excursion low-mid speaker and the 1.4” compression driver have strong but light Neodymium-Magnets. The 3” membrane of the compression driver consists of a special material that has a clearly reduced distortion factor in comparison to a titanium membrane. With CPD 12, KS AUDIO has responded to the demanding needs of the professional user with a modular self-powered loudspeaker producing the highest audio quality in a compact size. There are many applications in which CPD 12 can be used: Theatre, Live-stage Music, in large rooms or tents, as a delay system for long-throw, or as a compact top in combination with the CPD W1, CPD W2 or CPD WL Sub-woofers.
The speaker cabinet construction is, like any KS AUDIO system, built from birch plywood with an extremely durable PU-coating. All RAL colors available. Another special feature is the two multipurpose fittings on the back of the speaker. Allowing the installation of different fly-ware and connectors, which are safely interlocked by quick release pins. There is a pole mount in the bottom of the cabinet and a protective steel grill on the front, with or without acoustic foam, are further features of this premium product. 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 inputs are XLR F+M connectors. The control panel also has a digital volume control to individually adjust for each venue and a digital delay reaching up to 48 m for decentralized PA systems. There is a Lo Cut switch for speech reproduction or for adding a subwoofer to the system. Operation and set-up with a PC using KS AUDIO REMOTE3 Software is also possible via an Ethernet connection.
The power supply on the CPD 12 operates on AC 110-240V with soft-start using PowerCon in/out.
