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, which assures that your receiv- er or amplifier will see a safe operating load when playing mul- tiple speaker pairs simultaneously. Since most receivers and amplifiers are not rated for use below a 4-ohm load, you must 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 pairs 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 that corre- spond to the speaker pairs you wish to play. Set them to the ON position.
