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
