Matching Speaker Impedance

 - The Rogue 88 provides options 

for either  4 ohm or 8 ohm speakers. The  impedance selected will 
depend on the speakers used. Consult either the owner’s manual 
for your speaker or your local dealer for the correct choice. To 
switch impedance setting, refer to figures 5 and 6.  Note - the 
amplifier is factory set for 8-ohm speakers. 

 

Using a 5/16” wrench, remove the outermost nut from the 
red binding post.  

 

Remove the wire and lug marked 8 ohm from the binding 
post. Leave the wire and lug marked feedback in place. 

Warning-Never remove the lugs marked feedback or ground from the 

binding posts.  Doing so could cause permanent damage to the unit 

 

Remove the polyurethane tubing from the unused 4-ohm 
wire and lug. 

 

Place 4-ohm wire and lug onto red binding post.  

 

Place polyurethane tubing on the 8-ohm wire and lug.  

 

Replace nut onto binding post and tighten with wrench.

9)

 

Connections to other components

 -. The input connections from 

the preamplifier are made via RCA jacks on the rear of the 
amplifier. Be sure to use high quality interconnect cables - they 
do make a difference.
