64-channel audio metering and alarm system

The SierraView AM-xx2 is a networkable multi-channel audio metering device that can be fitted with analog, AES/EBU and Dolby Digital audio input cards. The AM-xx2 serves as an auxiliary audio interface for the SV-MV-xx by passing audio metering data via LAN to the SV-MV-xx. This is useful when other MV-xx configuration priorities leave insufficient space for direct audio interfacing.

→ Sierra Video AM-xx2 64-channel audio metering and alarm system
→ 1RU rack-mountable frame with removable front panel
→ Multi-channel color bargraph display
→ Six standard meter systems and ballistics with peak hold facility
→ Three bargraph color sections
→ Alarm detection for audio loss, over level, out-of-phase on adjacent pairs & carrier loss (as a pplicable)
→ Alarm status indicators
→ 4 audio input card slots, each supporting 16 channels (8 pairs)
→ Analog & AES/EBU audio formats supported
→ PAL/NTSC video input for frame synchronization
→ Streams audio level / alarm data & selected audio channels over a TCP/IP network
→ Data I/O on LAN, USB-2 & RS232 / RS422
→ System configuration menu
→ Audio input, LAN/processor and audio monitor cards accessible behind front panel
→ Optional audio monitor output card (4 pairs balanced analog & AES/EBU)
→ Optional Windows® software for configuration, remote monitoring and data logging
→ Analog with 24dB capability
→ AES/EBU (balanced /unbalanced selected by jumpers on PCB)
→ I/O @ 115Kbps (data out, alarms out/reset, parameter read/set) available as either RS-232 or RS-422
→ I/O on USB-2 (data out, alarms out/reset, parameter read/set)
→ Up to 4 pairs audio monitor outputs running on the USB-2 compressed
→ All 96kHz AES/EBU channels re-sampled at 48KHz for resynchronization with internal clock
→ The USB-2 works at 6.144MHz plus level & alarm data I/O on LAN port (data out, alarms out/reset, parameter read/set)
→ For all data outputs, audio meter scale/ballistic data will be in dB
