How to Enhance Presentations with Dialogue
A CD player or other audio source can be plugged into the
unused INPUT. Mixing of the computer audio output with
another audio source can be accomplished by using the
volume control or ON/OFF switch on the second audio source.
A typical example may be as follows:
A lecturer may want to interject dialogue into a multimedia
presentation. If the lecturer has a wireless FM microphone
system, the output of the microphone receiver can be
connected to the unused input on the ACS45.1. When the
lecturer wishes to make a comment, he either turns on the
microphone switch to speak or he can raise or lower the
microphone volume control to mix his voice with the
computer audio program. Any other audio device can operate
in the same manner.

Troubleshooting
When first installing a new system some simple instructions
may be overlooked which can cause the unit to be inoperative.
Please make the following checks:
•Make sure all connecting plugs between the satellite
speakers, subwoofer (if applicable) and computer are fully
seated.
•Make sure the wall power outlet or power strip has power.
The outlet can be checked with a lamp or some other
appliance. If the power strip has a switch make sure it is
turned on.
•Make sure the power switches on the satellites and
subwoofer (if applicable) are turned on.
•It is possible to test the unit by pulling out the audio cable
that is connected to the computer and connecting it to an
alternate audio source such as a portable CD player.
•When the unit is operative, vibrations from the
speaker sound can cause other loose objects to
vibrate. These extraneous vibrations may lead to the
erroneous conclusion that the speakers are defective.
In most instances, removing the vibrating object cures
the problem.
