That would be the clearly documented options --resample and --downmix
(the latter mixes stereo down to mono streams, the former does sample rate
conversions).

If you want to enforce a bitrate, yes - you'll have to use the managed bitrate
modes. If you merely want to encode at a lower bitrate (but one which may
vary) you can still use the quality modes.
