The AES DA 16, six XLR output, one-input AES/EBU distribution amplifier is ideal for distributing AES/EBU signals or wordclock. It features dual (2x) power input jacks to allow for redundant power with an optional second power supply. The systems transformer isolated input uses a standard XLR audio jack for balanced AES/EBU signals. The AES input is distributed to 6 transformer isolated output XLR jacks. An internal AES/EBU activity detector provides local and remote signal monitoring via front panel LED indicators and a SPDT alarm relay. The alarm relay contacts are available on a rear panel plug-in euro-block connector. Signal bypass is built-in with the XLR AES input passively routing to AES output 1 in the event of power loss.Main Features: 16 AES/EBU distribution. Jumper selectable AES input termination: 110-ohm, 75-ohm, open. Dual (2x) power input jacks allow for redundant power with an optional second power supply. Input signal monitoring with LED indicators and SPDT alarm relay output. XLR inputs and outputs with standard pinout. Signal bypass on loss of power, Input 1 to Output 1. Fully RFI proofed. Surge protected internal power supply, an 9 VDC desktop universal switching power supply with domestic connector supplied. Up to two units may be mounted on the optional RA-1 rack shelf. Desktop and wall mounting are also possible. A second power supply is optional, allowing for redundant power.
