The AES Digital DA 2x4 Distribution System from Henry Engineering is a 2 x 4 distribution system for digital audio signals. It can accept either an AES or S/PDIF digital audio stream, and create four identical AES outputs. The AES DA is 100% bit-accurate and transparent to the source, adding absolutely no delay or latency to the signal. The AES input and all four AES outputs are individually transformer-balanced and isolated from ground. The S/PDIF input signal is converted to an AES standard level and source impedance. The AES I/O is via XLR connectors; Pin 1 is connected to the AC "safety" ground. The S/PDIF input is via an RCA connector; the shield is isolated from the AC ground. No user adjustments or calibration is necessary. A blue "Signal" LED confirms the presence of an input signal.
The AES Digital DA 2x4 is powered with a built-in AC power supply, which can be set by the user to operate on either 115 or 230 volts AC. The AES Digital DA 2X4 is 1/3 rack wide, and can be mounted using the optional Rack Shelf. It can also be mounted with Henry Engineering's Desk Mount Kit or the wall/ cabinet mounting brackets.
