4x 700W Installation Amplifier
The DAP SI-4.700 is a compact and lightweight 4-channel power amplifier for fixed installations. In a 1U rack space, it delivers 4x 700 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 features a clip limiter and DC output protection to prevent speaker damage. Overload and output short-circuit protection safeguards the amplifier from failure, as does over-temperature protection and high-temperature power attenuation. Signal, Clip, Fault and Power LEDs indicate the amplifier's status. The output level can be adjusted for each channel using the volume controls. Gain can be set on the rear panel for either a 0.775 V input or 32 dB gain, and a mode switch selects stereo, mono and bridge modes. The universal switched-mode power supply uses active PFC and soft-switching technology, accepts input voltages from 100 to 250 V AC and is optimized for the audio power amplifier.SPECIFICATIONS
