Subject: Volume gain question

Another issue I need clarification on . . . in reviewing the captioning
notes from the last conference call it appeared there was discussion about
508 aligning with the current FCC requirements and testing for "volume
control" (as they put it) which I assume is 68.317. If that is correct, the
requirement is for a minimum of 12 dB of gain and no more than 18 dB of
gain. It looked like from the captioning, folks were using the 18 dB number
as what the FCC requires, when that is actually the max. I know there was
also discussion about moving to a maximum output level rather than a gain
level and that might eliminate the whole issue of 12 vs. 18 vs. 20. But
just wanted to clarify that I've got the right info about what the FCC
actually requires.

You are reading the FCC rules correctly - that is the maximum of gain
allowed. And you are correct that our discussion focused on reducing the
variability of how companies interpret the volume control requirment by
having a standard metric by which to assess all products, and requiring a
certain amount of amplification above that specified level.

The other area that this issue shed light on is that if there is a
range, the minimum is what will be accomplished by most companies.
It is unlikely that most companies will seek the high end of the
range. On the phone call where this issue was discussed, I believe
there was only one company that exceeded the 12 db range. :)

Best,
