It is an adapter which converts between Meridian’s Speakerlink connections and non-Speakerlink connection-types.
A single Speakerlink socket is “broken out” to the following:
• Digital audio on an RCA phono socket
• RS232 on a 9-pin D-Sub socket
• Meridian “Master Comms” on a 240° 5-pin DIN socket and a BNC socket (in parallel)
• Meridian “Slave Comms” on 180° 5-pin DIN socket and a BNC socket (in parallel)
No. There are use-cases which involve only current Meridian products.
No. It is a passive component and does not need external power.
No. Although counter-intuitive, there are use-cases where a Slave loudspeaker is connected to the Master Comms socket. If DIN connections are used, this will mean that a “5M” lead may be connected to a Slave loudspeaker. The data-sheet features an example of a system where this is done.
Yes. The two pairs of sockets for each of the Comms types, “Master” and “Slave, are wired in parallel. However, there are no internal connections between the two pairs of sockets; i.e. Slave and Master connections do not meet each other inside the case.
