3-3 Connection of Audio Cables
Cable connection plays an important role in the long distance audio transmission.
Improper connection will result in interference. For example:
(1)Connection for Unbalanced to Balanced transmission cable:
Practical example: after the audios from signal source of mono RCA output, they go
through to the IT-12M balanced input “LINE IN” (φ6.3mm jack) via unbalanced
output.

(2)Connection for Balanced to Balanced transmission cable:
Practical example: After the audios from wired and/or wireless microphones are
mixed via the mixer, they go through to the IT-12M balanced input “LINE IN”
(φ6.3mm jack) via balanced output.
The cable can be as long as 200M
