4. Poor audio quality at the receiving end
Only use powered speakers with the receiver. It is also good practice
to set the audio level (volume) output of the PC about 1/2 to 2/3 from
the maximum and use the volume knob of the speakers to adjust the
volume to the desired level. A low volume signal output from the PC
reduces the signal-to-noise (S/N) ratio, whereas too high output
amplitude can cause saturation and clipping to occur.
4.2 Calling Hall Research
If you determine that your sender is malfunctioning, do not attempt to
repair the unit. The unit contains no user serviceable parts. Opening
the unit without written authorization from Hall Research will void the
warranty.
Contact the Hall Research technical support department at 714-641-
6607. Before you do, make a record of the history of the problem. We
will be able to provide more efficient and accurate assistance if you
have a complete description, including:
• Nature and duration of the problem.
• Components involved in the problem – that is, what type of
cable, makes and models of computers and monitors, etc.
• Results of any testing you’ve already done.
4.3 Shipping and Packaging
If you need to transport or ship your wallplate, package it carefully (we
recommend that you use the original container), and before you ship
the unit back to Hall Research for repair or return, contact us to get a
Return Material Authorization (RMA) number.
