Re: Bass Management System Development


~ Channel coupling and series looping.
Probably not. All digital filtering can be accomplished in one pass at higher quality than two passes.

This probably isn't a big deal. I don't really understand the digital limitations of looping one channel to the next for double the filters, but with a dozen filters per channel, I think most everyone would be satisfied.

If I'm remembering correctly, coupling simply allows both sets of channel filters to be input simultaneously. With REW automatically loading the filters into either channel, I don't see this as a major loss.


~ Three-way IN/OUT bypass.
Probably no analog bypass because we don't have analog outputs from the controller. Digital filters can certainly be cut in and out.

~ Hard bypass relay.
No.

I think these go together. I can't remember what the issue was with needing a hard bypass relay.

How would we set the input levels without bypass... again, I'm sure I down understand the process completely, but for the average guy like me, I'm seeing this is something we need to do (set input levels).

So when the unit is OUT, does the signal still get passed on to the sub?



~ LED filter indicators for both channels.
Probably not.

~ Front panel display.
Very limited

These tie in together. I assume by some of your other remarks that there will be some sort of monitor output and/or computer connection for monitoring/viewing the settings. So having a computer nearby is now a necessity and the manual method of doing things is out the door.




~ Retain normal required buttons and jog dial.
Probably not, possible IR remote capability

~ Front panel volume/gain to control output level to sub.
Probably not, possibly available over IR control.

We will either have to have these on the front panel or on the remote. Somehow we have to be able to make the adjustments, input filters, etc. OR, are you suggesting this will all be done via computer program that you will furnish?

I'm confused about these.



~ Linkwitz transform circuit.
Can't this be done with a digital filter? Looks like a shelf filter.

Not a major loss IMO. This was suggested because it is supposedly a relatively inexpensive add-on, but I don't understand how it all works... others can chime in on it.




~ Separate RCA mic monitoring and test tone output to allow for computer program monitoring.
Don't quite understand, certainly computer program monitoring is a priority.


If we have a mic input and SPL meter built in to the unit... that information has to get to a source that can read and display the information it measures. I guess maybe it's a given that this would be included.
