Common Audio Source and Mixer Connection
For the connection between DVD, CD and other audio source devices and the mixer, if there is a Canon balanced output interface, use a balanced interface as much as possible to connect, you can make or buy Canon to 6.35mm (also known as: 1/4?) The three-core 2-core shielded cable is connected to the mixer line interface (mark: LINE) (2+ corresponds to the tip T, 3- corresponds to the ring R, 1SH corresponds to the sleeve S).
Usually unbalanced RCA lotus socket output is more common, so you can make or buy a lotus to 6.35mm big two-core 2-core shielded cable and the mixer line interface (label: LINE) to connect (2+ corresponding tip T, 3- and 1SH correspond to sets of S). Or use a lotus-to-lotus 2-core shielded cable to connect to the mixer's stereo lotus connector (label: STEREO L/R). The cable should be as short as possible. It is recommended that the length should not exceed 3 meters, and the high-quality pure copper signal cable with large number of shielding layers and high density should be used as much as possible.
If it is unavoidable to lay a long unbalanced signal line (such as more than 3--5 meters), for example, output the signal from the unbalanced output port of the mixer to a recording device 3--5 meters away, or from 3-- 5 meters away from the computer output audio signal to the mixer, because the unbalanced signal interface has no anti-interference circuit design, it is recommended to add a passive DI box (abbreviation for Direct Injection, isolation transformer) to convert the unbalanced signal into a balanced signal Signal transmission, which greatly reduces the noise (mainly due to: electromagnetic field interference) introduced by long-distance unbalanced signal cables.
