Installation Considerations HDL-6 Power Handling The HDL-6 is designed for use with a receiver or amplifier having a maximum power output of 250 watts per channel at 8 ohms. Damage caused by the use of a higher-power receiv- er or amplifier will void the warranty. Consult your Niles deal- er, or receiver/amplifier manufacturer, if you are uncertain ...

The actual impedance load the HDL-6 presents to your receiver or amplifier will vary, depending on how many speaker pairs are playing, and the impedance rating of each speaker. If you have six pairs of 8-ohm speakers playing, the HDL-6 will present a 4.3 ohm impedance load to your receiver/amplifier. With six pairs of 4-ohm speakers playing, the lo ...

Avoiding Interference Speaker wires can act as an "antenna" for electrical noise. Locating speaker wires too close to a light dimmer or switch may cause a "buzzing" or "popping" sound to be heard through the speakers. If you must locate the HDL-6 wiring near electrical devices, route the speaker wires several feet away ...

Operation There are two ways to use the HDL-6. You may play one pair of speakers at a time, or play multiple pairs simultaneously. If you intend to play more than one pair of speakers at the same time, you will need to become familiar with the opera- tion of the HDL-6's PROTECTION button. Playing One Pair of Speakers At a Time 1. Make sure the ...

Playing Two or More Speaker Pairs Simultaneously 1. Make sure the amplifier or receiver power is OFF and set the volume to minimum. 2. On the right side of the HDL-6's front panel is a button labeled PROTECTION. This button activates the HDL-6's impedance correction circuitry. The circuitry assures that your receiver or amplifier will see ...
