Dante-enabled Product Catalog

The CA 4D is a 4 channel MOSFET amplifier with controller card system configuration technology, using digital controller cards D MOD or F MOD. Both exclusively supporting the KS AUDIO FIRTEC™ finite impulse response technology. When changing controller cards or when loading a new program from the internal memory both the inputs and the outputs are appropriately configured to reflect the correct set up.

Whether or not the system is configured as 4 single channels – 2 channel / 2 way – 2 channel with mono Sub woofer – 2 channel mono bridged high power sub woofer – 1 channel 3 way - L and R SAT configuration, nearly every combination of KS AUDIO speaker systems is possible. This allows for a wide field of application, from small and medium size concert sound reinforcement to speech reproducing at the highest quality.

The CA 4D is equipped with 4 independent analog FET power amp modules. Two of them deliver a continuous sinewave power of 700 watts into 4 ohms each. While the other two modules deliver half that power. The controller card and an applicable program determines the distribution of power to always deliver the maximum available. The high performance of the CA 4D amplifier is achieved by three balanced supply voltages. The power losses are substantially less than with any other conventional analog power-amplifier designs. A total of 40 quality selected power MOSFET transistors, deliver a maximum headroom. Soft clipping circuits working in conjunction with

the operating voltage, limit the NF signals and therefore enable the power amps to always work with a high damping factor as well as remaining fully regulated.

The power supply is a state-of-the-art, heavy duty wide-range switch mode design, with Power-Factor-Correction (PFC) built in. The start-up current is limited to assure maximum protection. A second power supply is used to independently supply the controller card electronics along with the low voltage cooling fans and to operate the stand-by switch. Excess temperature is dissipated by 2 fans. The air is taken in from the front panel inlet thru an easy to clean filter. It is passed through to the back panel outlet, while passing over the heat fins and the power transformer to cool these units down to nominal operating temperatures.

On the front panel there are 4 mute switches corresponding to the 4 channels of the amplifier. Each of these switches has a red LED below it to indicate the mute status. On the rear panel there are 4 Neutrik speakON output connectors. Their status is indicated by 4 green LEDs. The mains cable is connected via a PowerCon.

The housing is constructed of 1.5mm thick steel while the 19′′ front plate is constructed of 4mm thick anodized aluminum and has 2 handles for ease of use.

The 4-channel loudspeaker controller module with digital signal processing for amplifiers of the KS AUDIO series

CA 4D and TA 4D. A unique convincing solution for perfect sound and easiest handling. The KS D MOD controller module complements the F MOD modules for applications where no quick change of the loudspeaker systems is required - i.e. especially in the installation area.

The one-time configuration of the loudspeaker system is done on the module by a USB stick transmitting the data while the system is switched on. During that process, both the signal inputs and the power outputs automatically receive the correct function:

from four individual channels

via two channels in Bi-Amp

or high-power bridge mode

to a single-channel 3-way active loudspeaker system with woofer-bridge mode output, and optionally “BI-Amp” control.

a SAT mode is also available in which the L+R signal is summed up to mono sub-low.

In addition to digital signal processing with FIR filter tech- nology, the special feature of the D MOD is its complete operability and controllability via standard networks. An integrated gigabit switch allows daisy-chaining to the next device. The KS REMOTE PC software enables easy ma- nagement and graphically, easy to understand, operation of an unlimited number of controller amplifiers arranged in groups.

All inputs can be controlled either digitally or analogously. Simultaneous digital and analog operation is also possible. A network-audio transmission using DANTETM protocol is available as an option.

Despite the many new possibilities and state-of-the-art technology, the D MOD can replace an existing analog or digital controller by simple front-panel installation. This puts your public address system back on the cutting edge of technology.

The four-channel speaker controller plug-in module with digital signal processing for the amplifiers of KS series CA4D und TA4D. A unique and convincing solution for perfect sound and simple handling with DANTE option. The four-channel speaker controller plug-in module with digital signal processing for the amplifiers of KS series CA4D und TA4D. A unique and convincing solution for perfect sound and simple handling with DANTE option. Besides the digital signal processing with FIR filter technique, the specialty of this module is the complete implementation of all KS speaker systems. The configuration of your speaker systems is done menu-driven directly at the module,the signal inputs and the power output getting the correct function automatically: any mode of operation is possible - from four single channels via two channels in Bi-Amp or high-performance bridged-operation to one-channel 3-way active speaker system with bass bridged power amplifier and alternatively BI-Amp control. The control and display unit allows fast and comfortable operation: direction and input keys for the display as well as a rotary knob for the parameters.

4-channel power amplifier for F MOD with optional DANTE interface card. A unique solution for all applications in the field of professional sound reinforcement. From a linear 4-channel power amplifier to a “digital controlled multiway PA system”, any conceivable configuration is available simply by channel-wise program change or exchange of a controller module on the front. KS Audio TA 4D - 4-channel power amplifier for F MOD with optional DANTE interface card. With the newest Controller F MOD, all KS AUDIO systems can be operated with the most modern linear-phase FIRTEC equalization, simply by downloading new programs from the internal memory. 8 balanced XLR connectors and 4 Speakon power outputs are automatically adjusted in their function: the power outputs switch over to “bi-amp” or “bridge” mode when necessary, the XLR’s can be alternately used as input or output, both for analog and AES/EBU signals. One slot is intended for the optional DANTE card. Thus 8 further audio inputs are available. An Ethernet switch allows simple daisy-chaining.
