Do not use XLR and TRS jacks on the same channel simultaneously

for mixing or other purposes.

Figure 6. Balanced line

To use an unbalanced source, connect pin 3 (ring on TRS jack) to the

shield of the connector. If you leave one pin disconnected, you will lose

6dB in gain.

Figure 7. Unbalanced line connection

A better method for using unbalanced sources is shown in Figure 8. This is

similar to the connection for balanced lines, but pin 3 is connected to the

shield at the source. The hum and noise rejection for the cable is

equivalent to that for a balanced line. To minimize hum in the audio, use

balanced inputs whenever possible.
