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
about the power rating of your receiver or amplifier.
Amplifier Impedance Load
As more pairs of speakers are parallel-connected to a receiver
or amplifier, the overall system impedance becomes lower.
For example, if two pairs of 8-ohm speakers are connected
in parallel, the impedance will be 4 ohms; two pairs of
4-ohm speakers in parallel become 2 ohms, and so on.
Most receivers or amplifiers are not rated for use below a 4
ohm load. Most manufacturers do not recommend connect-
ing more than two pairs of speakers without using some
form of impedance correction.
The HDL-6 includes impedance-correction circuitry that
protects your receiver or amplifier from low-impedance
loads. The circuitry assures that your receiver or amplifier will
see a safe operating load, even when all six speaker pairs are
playing at the same time.
