WIRING THE SURROUND-550
The Positive ( + ) lead from your amplifier or receiver should be connected to the RED ( + ) "INPUT" terminal,
and the Negative ( — ) lead from your amplifier or receiver should be connected to the BLACK ( — ) "INPUT" terminal.
See Figure 1 above.
SPEAKER WIRE
The sound quality that you get from your Surround-550s can be affected by the type of speaker wire that you
use to connect them. While it is possible to use speaker wire as thin as 22 gauge to hook your Surround-550s up,
wire of less than 16 gauge will compromise their sound quality. For wire runs of up to 10 feet, 16 gauge wire is
acceptable. For runs up to 20 feet, you should use a minimum of 14 gauge. For up to 30 feet, use a minimum of 12
gauge, and over 30 feet should use 10 gauge. See the THX Installation and Operation Manual for more information.
There are a wide variety of premium speaker cables available from a number of specialist manufacturers. We
do not endorse any specific brand of premium cable, but we do recommend the highest quality cable that fits your
budget. Beware, though -- with cables, expensive is not always better. If you have any questions, contact your M&K
Home THX dealer for advice.
