Input Connections
Generally speaking, there are two rules to follow when connecting equipment outputs
to the inputs of other equipment.
1.Properly match the impedances of the outputs and inputs.
2.Connect low impedance outputs to high impedance inputs.
It goes without saying that not only input and output impedance matching, but also level matching should be taken into consideration. Each input channel of the
circuitry, so the usable signal level range is wide. Input impedances and levels are shown in the following table.

*Sensitivity is the level required to produce a program out level of +4dB. *0dB is referenced to 0.775V RMS.
All XLR Type connectors are electronic balanced. Phone jack is unbalanced.
If the line going from one piece of equipment to another is long (more than 5m), we
recommend that balanced outputs be connected to balanced inputs.
As is described in the beginning of the Operating Instructions Manual, the connectors of the
Pin 3 is hot (high, plus).
