I'd like to hold a short meeting today to discuss strategy for
addressing the 'PDif compression' problem. Recent tests indicate the
majority of the problem -- but possibly not all of it -- arises from
overdriving the T302 and/or input amp of the T304 module.
Keith and I would like to quickly recap the tests which showed
this. We'd like to then discuss:
* Are more tests needed?
* Do we fully understand the compression mechanism?
* Are we confident of the proper power levels?
* How best to 'reset' the modules to proper levels.
3PM in Rm 157 (first floor meeting room).
