HIGH DEFINITION SPEA KER SELECTION SYSTEM
HDL-6
Introduction
The HDL-6 allows you to connect up to six pairs of speakers
to your stereo receiver or amplifier and play any one pair, any
combination of pairs, or all pairs at once. You don't have to
worry about overloading your amplifier. The HDL-6 has a
protection circuit that keeps your amplifier running safely,
even if you have all six pairs of speakers playing at the same
time.

Features and Benefits
The HDL-6 offers a number of improvements over other
speaker selectors:
● High power handling capability of 250 watt/channel
continuous music power.
● Pre-printed Room Labels are included for easy identification
of speaker ON/OFF buttons.
● Rear-panel switch for constant or selectable impedance
protection.
● Self-cleaning, silver-plated switch contacts assure many
years of trouble-free use.
● Isolated left and right channel ground returns make the
HDL-6 compatible with all types of amplifiers.
● Massive copper traces on printed circuit board handle
large amounts of amplifier current, ensuring high dynamic
range and clarity.
● Two-piece removable connectors greatly simplify installa-
tion and hookup. All wiring can be attached directly to the
connectors before installing them in the HDL-6.

● Removable connectors accommodate up to 14 gauge wire
or "pins", making the HDL-6 compatible with most "highdefinition" speaker cables.
● 100% tested, electronically and acoustically, for frequency
response, distortion and power handling.
● Standard 17" width allows the HDL-6 to stack neatly with
other standard size components.
● May be used with 4, 6, or 8-ohm speaker systems.
● Ideal for both home and commercial sound installations.
● Only an 1/8" standard screwdriver and wire stripper are
required for installation.
● Frequency response:Flat (
+
0dB,-0dB) from 20Hz to20kHz.
● Ten year parts and labor warranty.
● Proudly made in the USA.

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 receiver or amplifier will void the warranty. Consult your Niles dealer, 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 connecting more than two pairs of speakers without using some
form of impedance correction.
The HDL-6 includes impedance correction circuitry which
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.
