Tender Specification: AAX-2.300 High Quality DSP Amplifier for Digital Audio Network System 2-channel system amplifier with DSP technology, 2 x 300 Watt. Developed for dedicated use in a digital audio network system that includes active loudspeakers with integrated digital amplifiers and DSP technology, master modules and other system components. Control software can be used to access all networked DSP audio devices via this amplifier. The device has a compact housing; an additional fan for active cooling is not required. Connections: The amplifier has two Speakon loudspeaker outputs as well as an input (RJ-45 in) for power supply, control signals and digital AES/EBU audio signals with 2-channel input routing. An additional output (RJ-45 link out) enables serial connection (Daisy Chain) to other system components.
