Connection example 1
Connection example 2
* TIA/EIA-568A standard Category 5 Shielded Twisted-Pair cable (straight type)
Abbreviated to "Cat. 5 STP cable."
The total length of LINK-to-LINK connection cables must be under 800 m (when connected using Category 5
STP cable).
a + b + c + d + e 800 m
7.4. Power Supply from the VM Amplifier to Remote Microphone
The VM amplifier can only supply power to one Remote Microphone. Therefore, each of the remaining
Remote Microphone(s) needs to have a 24 V DC power supply (AC adapter) of its own.
