LD Systems DJ300 Power Amplifier
The DJ300 is a value-priced, full-featured Class AB power amplifier with an output of 150W per channel @ 4 ohms and 250W in 8-ohm bridge mode. Its sturdy construction paired with low weight makes it perfect for DJs in mobile use and smaller permanent installations.
It has extensive protection circuitry, a low-noise cooling fan, and a power-on delay. It uses XLR and stereo TRS sockets as inputs and Speakon-compatible sockets and heavy-duty screw terminals as outputs. A ground lift switch helps eliminate ground loop hum. LEDs on the front panel next to the volume controls indicate functional status, overloading, and triggering of the protection circuit.
The DJ300 functions in the entire frequency range of 20Hz - 20kHz with high dependability, dynamics, and impulse fidelity.

8,5 kg | The LD Systems DP600 Power Amplifier offers an amplifiying level of 2 x 300 W 2 Ohm
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.

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 model L 500 is a 2 x 250 Watts Power Amplifier. Linear Precision Series power amps combine excellent audio performance, modern and innovative circuit design, meticulous and exceptionally rigid construction, and the highest levels of operational integrity and reliability with an appropriate and more than realistic price. The robust steel chassis provides outstanding torsional strength through L-shaped side panels reaching under the thick aluminium front panel. Thermal breakers prevent the power supply units from being damaged by thermal overload. Electronically controlled fans provide sufficient front-to-rear airflow and a special cool air diverter takes care of thermal stability. The fans? noise-level is extremely low which provides the possibility for studio use. If necessary, a supplied air-filter can be mounted behind the front panel ventilation louvres.
