You can connect up to four remote M132M microphones to the M130 matrix. The IP address fo
each M132M must be set properly.
To connect the M132M microphone, you have to use a CAT5. STP cable (we recommend
shielded twisted 8 pairs).
When you use a cable 8 pair unshielded twisted CAT5. UTP, don't connect the PIN6 (A-GND).
The M132M also works, but has less ability to suppress interferences.
The Pin correspondence of the M132M microphone's connector is:
