Impedance Matching Speaker
Selector

Introduction
The Wired Home SS4, SS6 and SS8 are low-profile
speaker selectors that allow you to distribute a
stereo speaker-level (amplified) signal to multiple
listening zones. These speaker selectors feature a
manually activated impedance protection circuit.
The protection switch can be turned ON to prevent
the impedance to your amplifier from dropping
below 5 Ohms, regardless of the number and
impedance ratings of your speakers. The protection
switch can be turned OFF when used as part of a
system incorporating impedance matching volume
controls, allowing you to get the most out of your
amplifier.
The terminals on the rear of the speaker selector
will accommodate up to 14 gauge cable; sufficient
for cable runs exceeding 100 feet. For shorter
distances, 16 ~ 18 gauge cable will suffice. For in-
wall installations, we recommend using CL-2 or
CL-3 rated cable for compliance with local building
codes. If unsure, contact you local building
inspector. When connecting a speaker and
amplifier, it is important to maintain polarity;
positive (+/red) to positive and negative (-/black) to
negative. Be careful to maintain correct polarity
between the amplifier, the speaker selector, the
volume controls and the speakers.
