Engine-400 ICEbricks Super Compact 400 W Amplifier Module
- Clip detect output signals high distortion
- Short circuit and over-current monitoring
- Click-free disable input
- Convection cooling, no heat sink is needed
- EMC pre-screened
- Simple mounting through wave soldering
- Over temp warning flag
- Very low building height
As the name suggests, the Engine-400 is the driving force in the ICEbricks-series from ICEpower. ICEbricks are a revolutionary way for building amplifiers using super compact, stripped-down, high-end building blocks. The approach and quality are not only unique not only unique among our amplifier modules category but also unparalleled by any other amplifier product. The Engine-400 offers high audio quality, low losses, small size, robustness, flexibility and long life.
Believe it or not; this small-sized PCB is an amplification module, capable of delivering 400 watts (RMS) into 4Ω or up to 300 watts (RMS) into 8Ω with excellent audio characteristics. The Sierra loop design keeps distortion at a very low level throughout the audio band. At the same time maintaining the first-order characteristic with -3 dB at 100 kHz gives a very low phase shift at 20 kHz. The output impedance of Engine-400 has is just a few milliohms in the audio band and the noise is less than 30 uVrms giving a dynamic range of 122 dB; that compares to a factor of 1.3 million! The high-density multilayer PCB acts as a heat sink, providing sufficient heat dissipation for playing music in 45 ⁰C ambient temperatures.
Building with the bricks
The ICEbricks, by themselves, do not offer the plug-and-play functionality most of our amplifier modules offer. However, in exchange, they provide you with maximum design freedom, without having to deal with complex switch mode electronics design. You can select your own input stage but also the electrolytic capacitors, filter capacitors, VA+/- and VDR regulators you prefer to use. You also can choose how to handle the protection alarm signals in your own preferred way. Looking at the five rail supply requirements might be daunting. This is where another brick comes to play. The ICEbricks AUX-plant is the solution; this DC/DC converter is specifically designed to supply the VA+/- and VDR voltages from your main supply to the Engine-400.
The ICEbrick motherboard is the plug-and-play solution. Combining two Engine-400's, one AUX-plant, storage capacitors, supervision, balanced input buffers and connectors to connect it to a +/- DC-source. It is the fastest and most convenient way of testing the performance of a system built on ICEbricks products.
