5. Operation

• Do not connect the loudspeaker to a DC power

source.

Any base that is likely to experience even slight

vibration is not suitable for mounting a loudspeaker.

• Be sure to mount your speaker on a solid, stable

and level base.

• Do not use this apparatus near water.

• Make sure that no objects or liquids get through

the openings into the loudspeaker.

• Do not block any ventilation openings.

• Connect the low-frequency loudspeaker to the

sine wave generator.

• Set all the output controls of the sine wave

generator to zero (full left position).

• Connect the sine wave generator via the

transformer to the mains supply.

• Adjust the sine wave generator to obtain the

desired output (frequency and amplitude).

If you let your loudspeaker run at or near its power

limit, the integrated protective circuitry may

temporarily disconnect the tweeter. In this case,

there is no danger of causing permanent damage.

• Lower the amplitude to allow the tweeter to

automatically come online again.

damaged in any way, liquid has been spilled or

objects have fallen into the apparatus, if the unit has
