Are speaker selectors dangerous?

    I have a brand new H/K 525 that I do not want to harm in any way, shape, or form. I need to send audio (stereo) information to another room that is wired to the same location as my H/K 525. Someone recommended that I use the Niles HDL-4 speaker selector to drive "room b" stereo speakers, but I am concerned that the load would be harmful to the receiver.

    I have the system configured as a 7.1, so I cannot utilize the "multi-room" feature H/K offers. The "room b" speakers are small Outdoor polks Atrium45's (see specs below).

    Will a speaker selector be harmful to use?

    If not, which speaker terminals should I split? The fronts?

    Which speaker selector would you all recommend?

    Thanks for your help.

    Brian,

    Speaker selectors like the Niles are designed to maintain a proper load to the receiver’s amplifier section. The harm would be in not using one.

    Since you’re intending to power stereo speakers at the remote location, use the front L/R mains.

    Thanks for the feedback Wayne. So this wont pose too much load for the Front left and right channels?

    Thanks again!

    No. These things will maintain an 8-ohm load to the amplifier.

    Radio Shack also sells some – might be a little cheaper and more readily available than the Niles.

    No - they are passive devices that maintain the proper load with (I think) resistor networks.
