Rondson - DA-500DP

2 channels, class D, 2 x 500 W main power amplifier. The class D circuit typology offers great power with small dimensions and weight. Equipped with a variable speed cooling fan with termal sensor, it has a 100 V (20 ohm) output. One of the most interesting aspects is given by the possibility of being powered at 220 V_AC or with a 24 V_DC battery. The optional fault monitoring module enables the switchover to a standby amplifier or loudspeaker line in the event of an amplifier or loudspeaker line failure if the FS-3381 switching system is connected in between. A level reset relay contact on the output terminal block allows, in case of emergency, the broadcasting of calls on 3 or 4-wire lines that need a 24 V_DC power supply.
For maximum reliability, an Overload protection circuit and short-circuit limiter plus over-voltage protection circuit have been provided. Audio Priority and Remote Control input terminal. A 200 Hz high pass filter has also been implemented to improve sound quality.
Signal inputs on Euroblock screw terminal block.Technical characteristics
