6 Zone Stereo Speaker Selector

CongratulationsonyourpurchaseofthePhoenixGold 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.

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
