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.
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.
● Removable connectors accommodate up to 14 gauge wire or "pins", making the HDL-6 compatible with most "high- definition" speaker cables. ● 100% tested, electronically and acoustically, for frequency response, distortion and power handling.
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.
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.
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.

Installation 1. Select a convenient mounting location for the HDL-6. 2. Run all the necessary wiring to the HDL-6. Label the wires for future reference.

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 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.

Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maximum) listening level. Be careful not to overdrive or "clip" your amplifier.
