The Digi 400 A and 800 A are Class D amplifiers in 1 RU. By offering an unparalleled combination of dedicated amplifiers, channel density, SMPS and operating efficiency on a single board, for each channel, these amplifiers present convincing performance and cost saving solutions. The SMPS is designed for large headroom like a conventional linear unregulated power supply.
These amplifiers incorporate extensive protection features to safeguard internal circuits and connected loads. With fault indicated, the amplifiers mute and the output conditions are rechecked after every 1 second, and latched after 10 seconds if the short circuit at output remains.
A modular design aids in quick and effective servicing. The Digis are not only great solutions for indoor installs but also can be used to power small PA setups and stage fills / monitors.
