binding posts to control additional entertainment electronics. The External Turn-on
feature was specifically intended to control Pass Laboratories power amplifiers, but
may in fact control items from other makers with similar features.
The binding post red terminal conveys a 12-volt positive voltage and the binding post
black terminal is a ground reference voltage. Please check the owners manuals of
your ancillary equipment for particulars of compatibility. If you have a question,
please contact the Pass Laboratories factory.
Specific to Pass Laboratories power amplifiers is the requirement that the power
amplifier be placed in standby from it’s front panel control before using the remote
turn on function. The power amplifier’s onboard stand-by switch over rides the pre
amplifier control with respect to the “on” command. This is intentional so that the
power amplifiers may also be controlled manually.
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.
