Featuring remote location control and monitoring from anywhere is now possible, thanks to the A800D series' web-based interface. View and update volume levels or verify amplifier status from your office location. Thanks to downloadable log files, you can verify the need to dispatch a technician without a site survey or relying on end-users to supply the status information you need to troubleshoot. Saving time saves money and your peace of mind is worth even more.
Onboard DSP, a sleek new appearance, MOH (music on hold) output, two available 900 series module slots, plus TOA's legendary quality and reliability (including a 5-year warranty) make this an ideal choice for new and existing systems. Mic inputs 1-4 have phantom power available and 5-6 feature priority audio ducking with depth control plus a stereo RCA record out!
