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.

COMPACT MODERN DESIGN
Compact size (2U-Rack Height) with up to 1200W per channel@2ohms
these amps save valuable rack space without compromising power output.
HIGH CURRENT TOROIDAL TRANSFORMER
A high-current toroidal transformer saves rack space
and minimizes hum and noise.
EXCELLENT SOUND QUALITY
The low T.H.D.(0.05%) and high damping factor (400 or higher)
gives excellent sound quality.
2 STAGE POWER SUPPLY
The high-power units (L1800 and L2400) have a 2-Stage Class-H design
that maximizes their performance.
EQUIPPED WITH 30Hz or 50Hz HPF
All amplifiers are equipped with high-pass filters on each channel to
help maintain sound quality, yet help protect the loudspeakers.
EXTENSIVE PROTECTION CIRCUITS
Extensive protection circuits monitor over voltage/current conditions, overheating,
output shorts, and DC voltage to improve performance and reliability.
CLIP-LIMITER CIRCUITS
Clip-limiters on each channel are provided to help prevent
distortion due to excessive signal levels.

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!
