Installation and Connection Procedures
The
1.Route the speaker cables from each speaker zone and the amplifier to the ISM speaker selector.
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 appropriate speaker terminal and insert the stripped end of the cable into the speaker terminal. Be sure to observe proper
4.Release the spring loaded lever to clamp the cable in place. Gently pull on the cable to ensure it’s secure and properly 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. Please check each zone appropriately including 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
Installation Precautions
•Under no circumstances disable the power protection circuit unless your amplifier can handle the combined impedance of all zones activated. For example, a ISM6 with six pairs of 8 ohm speakers will present the amplifier with a 1.33 ohm load per channel with the power protection circuit switch in the “OFF” position. This may damage your amplifier or cause it to shut down prematurely. With the power protection circuit switch “ON”, the amplifier will see 6.33 ohms per channel which will not present a problem for most amplifiers. Please consult your authorized dealer and/or the owners manual for your amplifier for complete details.
•Power handling without the protection circuit switch engaged is 140 watts per channel for ISM4/ISM6 and 200 watts for ISM8.
•Power handling with the protection circuit switch engaged is 70 watts per channel for ISM4/ISM6 and 100 watts for ISM8.
•Never place the ISM’s where they will be exposed to excessive moisture or heat. Allow for a 1 inch of clearance above the top of the unit.
1 inch • 25mm Minimum Clearance Recommended
