2-channel installation amplifier (2x 1800 W)
The DAP SI-2.1800 is a compact and lightweight 2-channel power amplifier for fixed installations. In a 1U rack space, it delivers 2x 1800 W into 4 ohms, is capable of driving 2-ohm loads and can be bridged for even more power. It is designed for low impedance and high current, with excellent stability.
It has a clip limiter and DC output protection to prevent speaker damage. Overload and output short protection protect the amplifier from faults, as do over-temperature protection and high-temperature power attenuation.
Signal, Clip, Fault and Power LEDs indicate the amplifier's status. Output level can be set for each channel using the volume controls. Gain can be set on the back panel for a 0.775 V input or 32 dB gain, and a mode switch selects stereo, mono, and bridge modes.
The universal switching power supply uses active PFC and soft-switching technology, accepts input voltages from 100 to 250 V AC and is optimised for the audio power amplifier.
