Notes for Virtual Switches, Page Two
1. Because the Alpha-Link AX and MADI-AX units carry three ADAT ports, there are three ports to choose from when
selecting an ADAT clock source. To enable one of the three ports to be selected the first two option switches
operate together.
2. For Alpha-Link MADI-AX only. When EXT is selected as the clock source, this can optionally be MADI instead of a
separate Wordclock feed. If MADI is selected here the clock signal embedded in the incoming MADI stream can
be used as the clock source.
3. The Alpha-Link MADI-SX and LIVE units can optionally lock to one of the four AES/EBU inputs provided on AES/EBU
port ‘A’. To enable one of these four inputs to be selected the first two option switches operate together.
For the Alpha-Link unit to lock to one of these inputs requires that the sample rate converter on that input is
also bypassed – see point 5. below.
4. When EXT is selected as the clock source, this can optionally be MADI instead of a separate Wordclock feed. If
MADI is selected here the clock signal embedded in the incoming MADI stream can be used as the clock source.
Note that for Alpha-Link MADI-SX this option defaults to Wordclock whilst Alpha-Link LIVE defaults to MADI.
5. Sample rate conversion is provided on the four AES/EBU inputs on AES/EBU port ‘A’. These converters can be
switched out in pairs.
