KS-Audio, CPD-1 - 10"/1.75" Compact PA loudspeaker - HDSP™ integrated amplifiers and 2ch. DSP
The CPD 1 is the smallest member of the HDSP™ family, but it makes full use of this amazing technology. As can be expected from KS AUDIO, the components; speakers, filter components and later also the presets for the optimization of the impulse response, have been assembled with great developmental zeal.
The 10′′ long-excursion speaker comprises a powerful lightweight neodymium magnet. The ring diaphragm of the 1.75” driver consists of a special film that generates significantly lower distortion than comparable titanium diaphragms.
The 2-way DSP controller amplifier built into the rear operates with very high efficiency and requires no cooling fan. The FIR crossover and EQ filter shapes are precisely matched to the loudspeakers, and limiters ensure safe operation.
The power electronics include a Class D output stage for the low-midrange chassis and a Mosfet output stage with best audio properties for the HDSP™ driver.
The electronically balanced input is designed as XLR F+M sockets.
In addition to the mains connection, further operating elements are available: A digital level control for individual adjustment to the location and a delay of up to 40m for use as a delay loudspeaker in relation to a main loudspeaker system.
The power supply unit of the CPD 1 operates with internal changeover at AC voltage mains of 117 or 230 V. The inrush current is electronically limited. The connection is made via a PowerCon F connector.
With the CPD 1, KS AUDIO offers the demanding user a universally applicable 2-way sound reinforcement speaker of the highest audio quality and in a highly compact format. There is practically no field of application where the CPD 1 cannot be applied successfully: sound reinforcement for theaters, live-music stages, area-wide decentralized sound reinforcement of large halls and tents, delay system for remote areas.
Particularly fine is the combination with one or more CB 18 powered subwoofers.
As in all KS systems, the cabinet construction is made of birch multiplex and provided with an extremely robust anthracite PU coating. On request, the surface can be lacquered in any RAL colors. A protective steel grill with or without acoustic foam is another feature of this high-quality product.
