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 connection diagrams for the different connectors. RCA input connectors can also be used as
unbalanced inputs.
Connect microphones or balanced line-level sources to the balanced inputs of the mixer amplifier. 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 amplifier output connectors, we recommend the use of pre-assembled or professionally assembled
speaker cables of high quality and of sufficient 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 amplifier and the
speakers. Wire gauges apply to 4-ohm output.
NOTE: Custom wiring should be performed by qualified personnel only. Class 2 wiring is required.
