The DMM104 from ATI Audio is a distribution amplifier for digital audio signals. The unit accepts AES/EBU and S/PDIF digital signals on four connectors - XLR, BNC, RCA coaxial and TOSLink.
It then outputs a clean copy of the original data stream to four RCA coaxial S/PDIF outputs and a single TOSLink optical S/PDIF output, without modifying the signal in any way (such as adding copy protection, for example.)
Note:
Requires an optional 24VDC power supply
Accepts AES/EBU and S/PDIF digital audio signals from an XLR female 110Ω line, a BNC or RCA 75Ω line or a TOSLink optical fiber
Outputs the an unaltered and clean copy to four RCA coaxial S/PDIF connectors and a single TOSLink optical S/PDIF output
Provides a signal bandwidth of 12MHz to handle digital audio sampling rates of 27kHz to 96kHz
Propagation delay through the DMM104 is less than 100nS and jitter is under5nSp-p
All electrical inputs and outputs are transformer isolated, floating and DC blocked to eliminate ground loop hum and jitter, and to prevent transformer saturation due to accidental superimposed DC line voltages
All inputs and outputs are properly terminated for minimum signal reflection
