DII1100.4 - 1100 Watts Class-D 4-channel Amplifier

The DII1100.4 packs 570 watts bridged per channel pair into a 7.2" x 5.4" footprint, making it a practical choice for builds where rack space is limited but output demands aren't. Class-D efficiency keeps idle current draw to 1100mA while maintaining a frequency response of 10Hz–26kHz. Controls sit on the top panel under a protective cover, keeping the sides clean for tight installations.

• 4-channel Class-D output: 270W x 4 at 2 ohms or 178W x 4 at 4 ohms (14.4V); bridges to 570W x 2 at 4 ohms.
• Top-mounted control panel: All adjustments accessible from above, protected by a removable cover.
• Flexible turn-on modes: Selectable REM, VOX, or DC trigger for integration with virtually any head unit setup.
• Full crossover section: Independent HPF and LPF, each adjustable from 30Hz to 300Hz.
• 2/4 channel input switch: Accepts stereo or four-channel sources; includes RCA pass-through outputs for daisy-chaining.
• Clip detection LEDs: Visual indication at 0.06% THD+N to help set gain accurately.
• 4-way protection circuit: Thermal, voltage, speaker DC, and short-circuit protection built in.
