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.

Solid DYNACORD amplifier technology at highly competitive prices.
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.

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.
