ENGINE-400

We set out to make what we believe you, as a customer, will value. High audio quality, low losses, small size, robustness, flexibility and long life. With our Sierra loop-design we manage to keep the distortion at a very low level throughout the audio band, and at the same time maintaining a first-order characteristic with -3 dB at 100 kHz giving very low phase shift at 20 kHz. The output impedance of Engine-400 has been verified to just a few milliohms in the audio band, and the noise is less than 30 uVrms giving a dynamic range of 1.3 million times or 122 dB. Engine-400 uses the high-density multilayer PCB as heat sink thereby keeping the building height down. Low impedance connections to your PCB is provided through massive, gold plated, copper tellurium pins. As a customer, you select which electrolytics, filter capacitors, VA+/- and VDR regulators you prefer to use. You are also free to handle the alarms that is sent out from Engine-400 in the way you wish. This provides you with the maximum design freedom without having to deal with complex switch mode electronics design.
