The AU-A220 is a compact Class-D stereo amplifier with 20 W per channel at 8 ohm, designed for multi-room installations and zoned AV systems.
It can handle both analog and digital audio signals, integrating sources within the rack or receiving audio from a compatible matrix switcher for distribution to multiple zones. Its compact size allows for installation in rack cabinets or directly behind a display in the local zone, offering great design flexibility.
The unit is compatible with the RAX-300 series and can be powered, up to four units, by a single RAX-PSU-24V power supply. Input selection and volume control are available via front-panel buttons or RS-232, with a digital volume meter for precise adjustment.
