Wiring guide
Choose the input connector and the appropriate cable for each source.
We recommend the use of pre-assembled or professionally assembled 22-to-24-gauge balanced cables.
Figure 2.1 shows the connec
ti
on diagrams for the di
ff
eren
t connectors. RCA input connectors can also be used as
unbalanced inputs.
[Figure 2.5 Input cables and connectors]
Connect microphones or balanced line-level sources to the balanced inputs of the mixer ampli
fi
er. Adjust the
Gain accordingly. Connect unbalanced line-level signals to RCA connectors.
Choose the output connector and the appropriate cable for each source.
For the ampli
fi
er output connectors, we recommend the use of pre-assembled or professionally assembled
speaker cables of high quality and of su
ffi
cient gauge. You can use pluggable terminal blocks for your output
connectors. To prevent the possibility of shor
�
ng, wrap or insulate exposed speaker connectors.
Using the guidelines below, select the speaker wire gauge based on the distance between the ampli
fi
er and the
speakers. Wire gauges apply to 4-ohm output.
