64-channel audio metering and alarm system

The SierraView DATA-xx provides conversion of analog or AES digital audio (up to 64 channels) into data that represents audio level indication conforming to the most common international standards. The data may be sent to the SV-MV-xx for display, made available on a network as audio metering data for third party bargraph display monitoring, or used in any application where audio level indication and alarm functionality is required.

The DATA xx is housed in a 1RU rack-mountable frame.

→ Sierra Video DATA-xx 64-channel audio metering and alarm system
→ 64 audio channels input capability
→ 4 slots of 16 channels each
→ 1RU frame with split fixed and user removable front panel
→ All cards accessible in-rack from behind the removable front panel
→ 4 slots used for the input cards
→ 1 slot used for the processor board with data outputs
→ 1 slot for analog and AES/EBU monitor outputs
→ All cards interconnected using 96 pin DIN connectors and a backplane
→ Switch-mode PSU
→ Power switch on the fixed section (left side) of the front panel
→ 16 input channels
→ Input card types automatically recognized
→ On-board processor/logic
→ Outputs any 4 pairs of audio at 24bit resolution (to main processor board)
→ Level processing performed at 16 bit resolution
→ Input PCBs connects to interface board via 96 pin DIN connector
→ 8 x 25 pole, Sub-D for analog and AES/EBU
→ Other connector adapters to fit the 25 pole Sub-D
→ I/O on RS-232 @ 115Kbps (data out, alarms out/reset, parameter read/set)
→ I/O on RS-422 @ 115Kbps (data out, alarms out/reset, parameter read/set)
→ Above ports cannot be used together - they are simply the same port except for the voltage levels used.
→ Output on RS-422 for audio alarm units (third party). (Data out, alarms out/reset)
→ I/O on USB-2 (data out, alarms out/reset, parameter read/set)
→ I/O on LAN port (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 will be re-sampled at 48KHz so that everything runs at the same rate. The USB-2 will work at 6.144MHz plus level & alarm data).
→ Scale/ballistic data will be in dB
→ Up to 4 pairs, analogue or AES/EBU. 24 bit output
→ The AES/EBU inputs coming in at 96kHz will be re-sampled to 48kHz and sent out at 48kHz
→ Monitor outputs - balanced analog and AES/EBU. Analog outputs max 20dBu.
→ All firmware is stored in field programmable FLASH memory.
→ All cards are “hot-swapable”.
