Highlights & Key Technologies
 
Powerful Custom Installation
The DALI PHANTOM CI AMP-4750 DSP is a powerful custom installation amplifier with advanced digital signal processing and speaker presets that get the very best from any DALI PHANTOM custom installation setup. Powered by 4 x 750 watts of ultra-low distortion, Class-D amplification, this rack-mountable powerhouse includes low-noise fan cooling, integrated protection circuits and a range of connectivity options, including Wi-Fi, LAN and GPIO. Using any Wi-Fi-enabled computer, tablet or smartphone, the web-based PHANTOM AMP CONFIGURATOR also provides intuitive configuration and control of up to four DALI PHANTOM speakers or eight subwoofers in any home cinema.

Class D Amplification
With 4x 750 watts of Danish-developed Class-D amplification, the AMP-4750 DSP delivers effortless power, extremely high efficiency and ultra-low distortion. Designed for high-end CI audio and home theatre installations, this low-noise fan-cooled, rack-mountable powerhouse is the perfect match for speakers like our PHANTOM M and S-series speakers. And with so much headroom, it can power up to eight PHANTOM IW SUB S-100 in-wall subwoofers for epic movie experiences and can even be bridged into a 1,500 watt stereo amp to satisfy even the most demanding high-end enthusiast.

Fully Featured DSP
The intuitive web-based DALI PHANTOM AMP CONFIGURATOR helps you get the most out of even the most complex CI installation. With DSP tools like parametric equalizers, audio limiters and compressors, routing matrix, input/output settings, speaker delay and model-specific presets, the AMP CONFIGURATOR has the tools you need to get the very best sound from any installation.

Wide Range of Applications
Aimed primarily at high-performance home cinema installations based on PHANTOM M and S-series CI speakers and in-wall subwoofers, the multi-purpose AMP-4750 DSP amplifier can also power in-wall and in-ceiling speakers in a multi-room installation. And with 4 analogue, 2 digital inputs and 4 speaker outputs, this versatile amp is also a great power source for use in bars, restaurants, cafés, fitness centres and other retail environments.
