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. If you must locate the HDL-4 wiring

near electrical devices, route the speaker wires several feet

away from the electrical wiring.

Using the HDL-4 with Tube-Type Amplifiers

Virtually all tube amplifiers must have a load connected at all

times. If the amplifier to be connected to the HDL-4 is a tube

amplifier, be sure to always have at least one pair of speakers

switched on at all times. An alternative is to permanently

connect a 150 ohm, 5 watt resistor across the tube amplifier's

output in parallel with the HDL-4. See (Figure 1) on next

page for hookup diagram.
