QSC Attero Tech Axon DTH1620 16-Channel Dante/AES67 Network Amplifier

The Axon DTH1620 answers a problem specific to themed entertainment and immersive installations: many small speakers, each needing its own discrete channel, spread across a space where running speaker cable back to a central rack is impractical. It provides sixteen channels at 20 watts apiece, taking audio directly off Dante with AES67 interoperability so the only long run is a network cable.

Because it is optimized for Q-SYS, the amplifier reports into the same monitoring and management layer as the rest of the system rather than sitting as a silent black box. Low per-channel power is deliberate here, matched to the small drivers these installations actually use.
