The development goal during the conception of the CD 24/ CD 44 was to set new standards for sound quality and operating safety. In doing so, a high-resolution DA/AD converter (96 kHz / 24 bit) and a sophisticated limiter concept were used. Two fully automated independent limiters monitor and limit the cone excursions and the thermal load of the speakers using a sense connector at the amplifier output. Despite this complex circuit technology, the latency time is only 0.7ms. Every output channel can be used with individually parameter sets (macros) and saved as new pre-sets. The controllers operate with a mains voltage of 90 to 240 volts.
The 2 in 4-way speaker controller CD 24 has a 20ms delay per set of outputs. A RS-232 interface enables the remote control and monitoring of the device.
The CD 44 is a 4 in 4-way speaker controller, which processes analogue as well as digital signals in AES/EBU format. Filters to process signals are available in all inputs and outputs. A delay of up to 220ms per output can be selected. Eight different routings are available in the device. With the ethernet connector, the TCP/IP protocol can be used to monitor and operate the CD 44 remotely.
A further innovation with Kling & Freitag is the option 'AS' (axial symmetry). Starting immediately, this option is available for all systems of the CA series with monitor angles and facilitates the set-up of monitor pairs (horn to horn). A higher directivity in the mid-high range with minimized phasing can be achieved.
From April on the models CA1001 and SW115E are also available as Outdoor Installation versions. They withstand temperature fluctuations in moderate climate zones and do not accumulate condensation water. Therefore stainless steel connecting terminals with single PG cable fitting are used. Any handles, plastic sliders, stacking cavities and locking profiles, that exist, are being removed, and all visible screws are made out of stainless steel. In order to guarantee the longevity and safety of the speakers, they must still be protected from direct effects of the weather.
