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 a safe operating load when play- ing multiple speaker pairs simultaneously. Since most receivers and amplifiers are not rated for use below a 4 ohm load, you will need to activate the PROTECTION button whenever the overall system impedance might fall below 4 ohms. Use the following chart as a guide for setting the PROTECTION button.
"TECH TIP"
You will need to activate the HDL-6's PROTECTION button whenever the overall system impedance might fall below
4 ohms.
When playing the following speakers: | The Protection button should be: |
1 or 2 pair of 8-ohm speakers | OFF |
3 or more pairs of 8-ohm speakers | ON |
| |
1 pair of 4-ohm speakers | OFF |
| |
2 or more pairs of 4-ohm speakers | ON |
| |
Any combination of 4 and 8 ohm speakers | ON |
Set the PROTECTION button to the correct position using the chart shown above.
3.Locate the ON/OFF buttons on the HDL-6 which corre- spond to the speaker pairs you wish to play. Set them to the ON position.
