XP-30 Owner’s Manual
The monaural function is selected only from the front panel, it is not
available from the hand remote. When mono is selected, rather than
creating a true mono signal it creates a frequency dependent blend
of signal from two chassis. The blend has been chosen such that it
minimizes noise while maximizing information transfer.
The two blended gain chassis are joined to one another by a special
XLR cable The blend function was intended to address the special
needs of professional audio archivists who frequently work with
recordings of historical importance and dubious quality.
These professional archivists require circuits that transfer the last
iota of intelligible detail combined with the smallest percentage of
unwanted artifact (spurious noise). The blend circuit specifically
addresses this professional need.
As a casual listener you may find the “mono” function of value
when listening to any recordings that presumed a single point source
reproduction rather than two-channel. The high frequency blend of
the mono control frequently reveals performance nuances in these
recordings that would otherwise go unnoticed on a two-channel
system.
