Power Amp


 TA 2D front(1)

High Power Subwoofers



The versatile amplifier with perfect features: from a basic stereo power stage to a digitally controlled 2-way active loudspeaker system with network control and monitoring, any operating mode is possible.


However, the TA 2D finds its best application as high-performance amplifier for all KS woofers. For this purpose, the basic program is ideally matched with configurable parameters to the respective loudspeaker type. The actual set-ups are located on a chip card, which allows easy download of updates “in field”.

Two independent amplifier channels featuring a highly efficient 3-stage Class-H circuit provide the basic configuration of the TA 2D. Each power output stage comprises 24 fast FET transistors that guarantee superb audio performance with a frequency range of up to 50kHz.

The performance of the 2HE/19” amplifier with its 2x2000W is at the upper limit of the energy level that common 16A protected 230V circuits can supply. Already at 8 ohms there are 1,000W available, which is sufficient power to operate almost any loudspeaker.

The power stages are supported by a digital audio processor with high-quality 27 bit A/D converters using gain stacking technology. This allows the implementation of 2 single channels, a stereo or a 2-way system.

The signal processing programs for all KS full-range loudspeaker systems are equipped with the FIR filter technology FIRTEC. This means individually measured, phase-pure sound reinforcement systems with an unsurpassed sound resolution.

There is an unlimited number of possible programs available: heavy-duty chip cards serve as easy-to-handle program storages. They can also be used as a “key”, if a system must be protected against unauthorized access or operation.

Modern wide-range switching power supply featuring power factor correction.

Technical equipment:

48 FET power transistors with NF-conducted triple operating voltage

Regulated switch-mode power adapter with PFC and inrush-current limiting, plus separate standby power supply, loudspeaker outputs with relay power-up delay, protective circuit against low-impedance and electrical overload.

Two particularly silent running, temperature-controlled fans
