Wiring plans – Continued
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 shorting, 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.
CAUTION: Never use shielded cable for speaker output.
Maintain correct polarity on output connectors.
For each output channel, connect the output terminal block connector to the speakers.
Use terminals marked COM and 4Ω / 8Ω for low impedance speakers, or use terminals marked 25V or 70V, and COM for
high impedance speakers.
Connect the COM terminal to the negative (-) terminal of the speaker; connect one of the other terminals to the positive
(+) terminal of the speaker.
Output impedance and voltage are as shown in Table 2.1

NOTE: The impedances listed in Table 2.1 represent the total impedance of all speakers connected.
