chosen group or machine track. A stereo mixdown of all
the channels is possible with this method by selecting
them to an arbitrary pair of tracks across which the
mastering machine is hung. This is, in fact, the
mixdown technique used in many console systems
whether in-line or discrete monitoring. Although
entirely feasible, it is not the manner in which this
particular system is intended to be used, and is
becoming rarer in the commercial world.

Stereo mixdown is achieved in the same buses as the

multitrack monitor mix, the solo monitor function

making its home here, too.

A master group module contains the mix-amps,

fader, and line amps pertaining to the stereo bus

together with sundry other related things, like mono

summing (required for a monitor feed) and clean auxil-

iary bus access for extending the monitor mix (for effect

returns or temporary extra channels).
