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.

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!
