Description

The DAP SI- 4.900 is a compact and lightweight 4 channel power amplifier for fixed installations. In a 1 U rack space, it delivers 4 x 900 W on 4 ohm, is able to drive loads from 2 ohm and can be used in bridge mode for even greater power. It is designed for low impedance and high current, with excellent stability.

It has a clip limiter and DC output protection to prevent damage to the loudspeaker. The overload protection and short circuit output protects the amplifier from faults, as well as overtemperature protection and high temperature power attenuation.

The LED Signal, Clip, Fault and Power indicate the status of the amplifier. The output level can be adjusted for each channel using volume controls. The gain can be set on the back panel for an input of 0,775 V or a gain of 32 dB, and a mode switch selects stereo, mono and bridge modes.

Universal switching power supply uses active PFC technology and soft-switching, accepts input voltages from 100 to 250 V AC and is optimized for audio power amplifier.
