Speaker selectors are useful for isolating areas of distributed sound.  This can permit private listening and prevent disruption to offices or guest and children’s rooms.  They can be used as a distribution point when multiple speakers are connected to an amplifier.  This can offer a cleaner and more reliable installation while also helping to reduce wiring clutter. Speaker selectors help to protect the amplifier from damage by reducing or balancing the load. An 18 gauge wire is the minimum recommended size. For runs in excess of 100 feet it is best to use 16 gauge or larger.

WIRING NOTE:
A) Wiring to and from switch should be "CL-2 or CL-3" rated. Use 16 gauge or larger for runs in excess of 100 feet.
B) Strip ¼" off each wire. Ensure all strands are twisted together and inserted into respective terminals.
C) For 12 gauge and larger wire, trim some of the strands off to enable them to fit into the terminals.
D) Perform initial testing of selector at low volume level to prevent damage to equipment.

This is a "Common Ground" switch. It is not intended to be used with equipment which is incapable of operating with "common ground" connections. Consult the owner’s manual of the equipment to be connected. Severe circuit damage can occur to equipment not designed for "common ground" type connections.

CAUTION:
If no Volume Control is used with the IW-202 tie off pigtails as follows:
