AUDIO AUTHORITY AUDIO SOURCE CARD FOR HLX MODULAR MATRIX SYSTEMS
Audio Only Sources
The 2174 adds four 2-channel analog audio sources to an HLX matrix configuration for a maximum of 16 sources per system. The 2174 is the only source card that can be installed in slot 4, so even a configuration with 12 video sources can accommodate four more audio sources. The IR output jack provides a control pathway to send IR signals to sources from remote zone receivers via the Cat 5 zone cables.
