Mono class D power amplifier 1000W 100V - RONDSON DA-1000DP RON-02486

The RONDSON DA-1000DP is a mono Class-D main power amplifier rated at 1000 W RMS. Its Class-D circuit design provides high power while keeping dimensions and weight contained. It features a variable-speed cooling fan with thermal sensor and a 100 V output at 10 ohm. The amplifier can be powered by 220 V AC or by a 24 V DC battery. The optional fault monitoring module allows switchover to a standby amplifier or loudspeaker line if the amplifier or loudspeaker line fails, provided that the FS-3381 switching system is connected between them. A level-reset relay contact on the output terminal block permits emergency broadcasting of calls on 3-wire or 4-wire lines requiring a 24 V DC power supply. Protection includes an overload protection circuit, short-circuit limiter and over-voltage protection circuit, together with a power-on noise reduction circuit. The input terminal block provides Audio Priority and Remote Control connections. A 200 Hz high-pass filter improves sound quality, and the signal input uses a Euroblock screw terminal block. Power consumption is 1250 W. At 230 V, the listed consumption is: 1/8 of power, 5.6 A / 2.8 A; 1/3 of power, 8 A / 4 A; power rating, 13 A / 6.6 A. Frequency response is 40 - 18,000 Hz at -3 dB, S/N ratio is above 100 dB and harmonic distortion is below 0.5%. The high-pass filter is 200 Hz / -3 dB. Input sensitivity / impedance for PGM and PRIORITY is 0 dBu (0.775 V) / 60 kohm symmetrical. The power supply is 230 V AC 50 Hz / 24 V DC. Dimensions are 483 x 375 x 88 mm, corresponding to 2U, and weight is 21.5 kg.
