These amplifiers offer high, stable power output and a high efficiency factor on the high performance level and are therefore the ideal choice for driving a multitude of mobile and club systems. SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters.
The integrated, switchable Low-Pass Notch filter (a typical DYNACORD special feature) corrects the frequency response and optimizes the transient behaviour of loudspeakers.

BASIC Series - Intelligent Power
BASIC - that's meeting the tightest budgets and professional requirements in reliability, flexibility and sound. Alone or in combination with the other products of the Bittner portfolio. The consequent realisation of the Bittner quality standards indicates once more our understanding of the contracting business. It underlines our philosophy that cost consciousness has nothing to do with giving up standards. Compromise is a word unknown to Bittner Audio! The incorporation of detent potentiometers, clip limiter, protection circuits for any imaginable situation, as well as a first-class production process using only highest-quality components made the BASIC series the choice of most contractors.
Certainly more than basic!

The new DEEP2 amp series features four class-H power amplifiers with toroidal core offering amplifying levels from 2 x 400 W till 2 x 810 W at 4 Ohm. During the development of this series we attached a great importance to the reliability and the durability of the amps in continuous operation, this is why we used exclusively high end and selected components for the construction of these products.
The DEEP2 series features a Clip Limiter as well as every common protection circuits. These amps are 2 Ohm and 4 Ohm (bridge) stable in continuous operation. On the rear panel you will find all the common In- and Outputs.
The DEEP2 series will convince every user thanks to a dynamic and very clear sound which is perfectly adapted for Subbass applications as well as for multifunctional speakers. All models are lightweight and feature a robust steel plate housing and a very user friendly and compact design.
The DEEP2 series will prove to be a profitable and reliable choice for bands, renting companies and professional users thanks to its excellent price/performance ratio.
