เครื่องขยายเสียง ยี่ห้อ TOA รุ่น SX-2000AO
- 8 line level audio outputs, 2 local audio inputs can be mixed to individual outputs
- 8 control inputs and 8 control outputs
- Two LAN ports for redundancy of the transmission path
- Analogue bypass in case of a CPU failure enables simultaneous all-zone calls
- Audio output levels (post-fader levels) indicated on the level meters separate for each output channel
- Volumes adjustable for each channel by front volume controls or by the SX-2000 software
- The volume controls can be locked by SX-2000 software
- Any output channel can be monitored using the internal speaker
- Two power inputs for dual-redundant power supply system
- The SX-2000 system requires Ethernet switches. For an EN54-16 compliant system, the certified IES-3000 series Ethernet switches are to be used
- For an EN54-16 compliant system, the SX-2000 system is to be powered by VX-3000DS, VX-2000DS or VX-3150DS
