MRC88 / MRAUDIO8X8 QUICK START GUIDE 8

SPEAKER WIRE LENGTH

The maximum wire length for Zone Speaker connections is 150’ (39m) over 14AWG stranded wire.

•Speaker wire should be pulled in home-runs from the speaker locations to the MRC88 Controller, two pair for each zone.

•Always use quality stranded speaker wire for zone speaker connections.

•Label each end of the speaker wire with the Zone Number and Room Name to assure proper connection and assist in troubleshooting.

•MRC88 Speaker Terminals are 4-Ohm safe. Be sure the combined impedance presented to the speaker terminals by the speakers (or any combination of speakers) is greater than 4-Ohms.

Use the following Table to determine speaker wire gauge based upon the length of the speaker wire run:

Length of Speaker Wire Run		Gauge of Wire
30’	(9m)	18AWG
70’ (21m)		16AWG
150’	(39m)	14AWG
