The LD Systems DJ 300 is a fully equipped and very affordable Class AB amplifier, with a power output of 150 W per channel into 4 ohms and 100 W into 8 ohms. It is a robust and lightweight piece of equipment, ideal for DJs, mobile applications, and small fixed installations.

It features all protection circuits, a quiet fan, and delayed power-on. It has XLR and stereo jack connectors for the inputs, and Speakon-compatible connectors and binding posts for the outputs. A Ground-Lift switch prevents possible ground loops, and the front LEDs located next to the volume controls indicate the operating status of the limiter and the protection circuit.

The DJ300 has a frequency response of 20 Hz to 20 kHz, with great reliability, a wide dynamic range, and a faithful impulse response.
