Congratulations on your purchase of the Phoenix Gold
Innovative Home ISM Speaker Selector. This product
is designed to distribute stereo music to several
independent listening zones via connection with
your existing audio system.
Please read this Installation Manual to ensure the
proper installation and performance of your ISM
Speaker Selector.
ISM6
6 Zone Stereo Speaker Selector
Function of the ISM
The ISM is a low-profile speaker-level audio distribution
system with individual On/Off selectors controlling signal
distribution to separate zones. Pass-through amplifier
input terminals allow easy connection of additional ISM
selectors. User-selectable Protection circuitry ensures that
the combined speaker load impedance presented to the
amplifier never falls below 3 ohms per channel.
Installation and Connection Procedures
Polarity (+/-) for the input and output speaker terminals
is clearly marked on the ISM rear panel. Speaker
wire is coded to identify each conductor as either
positive (+) or negative (-). This may be by color coding,
or one conductor may have a printed marking or a rib
along one edge that you will not find on the other. Identify
which type of polarity coding that your wire is using and
which conductor is positive (+) or negative (-).
1. Route the speaker cables from each speaker zone
and the amplifier to the terminals on the ISM. These
terminals will accept up to 10 gauge speaker cable. Use of
speaker cable smaller than 16 gauge is not recommended.
Note: UL rated CL3 speaker wire is recommended when
running wire inside your walls. In many areas it may be
required by code. When installing your speaker wire, avoid
running the speaker wire parallel to any 120V power lines to
avoid picking up hum and interference from the power service.
If the speaker wire needs to cross a 120V power line at a
right angle this is acceptable and will not create a problem.
If you are uncomfortable with running the speaker wire yourself
in existing construction, it is recommended that you retain a
qualified custom home installation specialist or electrician.
2. Strip 3/8” insulation from the end of the cable and
twist the exposed end to avoid fraying.
3. Press the spring-loaded lever on the speaker terminal
and insert the speaker cable, carefully observing the
polarity.
4. Release the spring loaded lever to clamp the cable
in place. Gently pull on the cable to ensure it’s securely
connected.
5. The system is now ready for testing. Turn on the
sound system and set the amplifier’s volume control
to a moderate level.
6. Sound should be heard from each zone when its
button is depressed. Check each zone for proper left
and right connections by activating each zone with the
balance adjusted to full left and then to full right.
7. Attach the custom die-cut labels provided to the
buttons of the ISM, referencing each button to its zone
zone within the installation.
Recommended Speaker Wire Gauges
The resistance of the speaker wire in your installation
can cause your speakers to perform at less than their
optimum quality level. Excess resistance caused by
using an undersized speaker wire can result in loss of
detail and definition in the bass region of your audio
program, as well as loss of dynamic range. Over extremely
long wire runs you may even experience a loss of high
frequency content in the audio signal.
To prevent sonic degradation in your speaker installation,
total speaker wire resistance should be kept below
0.5 ohms. The following table lists recommended speaker
wire gauge versus wire run length.
50’ or less - 16 Gauge 2-Cond. CL3 Rated
50’ - 150’ - 12 Gauge 2-Cond. CL3 Rated
150’ - 200’ - 10 Gauge 2-Cond. CL3 Rated
