Automatic PurePath Autoformer
protection constantly processes how
many speakers are selected and
provides the purest possible path
from the amplifier to the speaker.
Ultimate fidelity for critical listening
can occur in any room at any time Âsimply select only the room you are
in and the PT selector automatically
provides an absolute pure direct
path to the speakers selected. As you
engage more pairs of speakers, the
PT selector simply inserts
Autoformer protection. Autoformer
protection splits the amplifier's
power among the speakers selected,
without wasting any power as heat!
As a result, compared to any other
speaker selector, systems with the
PT Series provide far higher
volumes when all speakers are
playing.
In fact, PT selectors deliver five
times as much power of resistive
selectors when all the rooms are on.

TECHNICAL DETAILS
No Service Call Buttons
Unlike other manufacturers, the PT
Series does not have "protection"
buttons that children or inexperienced
users could accidentally press.
Accidental deactivation of amplifier
protection can devastate your
equipment, requiring expensive service
calls and repairs. Audioplex PT Series
provides automatic protection. No one
can damage the audio system
The PT series of speaker selectors includes the PT-4 and the PT-6
accommodating four and six pairs of speakers respectively. The controls of the
PT series allow you to play any combination of speakers simultaneously.
Designed For Performance
The PT Series selectors are designed
and engineered to have ruler flatÂfrequency response and ultra-low
distortion. Audioplex delivers 20 to
20,000 Hz plus or minus 0.5 dB.
No Ventilation Neccessary
Since the PT Series incorporates
autoformer protection, no heat is
generated by the protection circuits. As a
result, the PT Series can be placed in
cabinets without ventilation or fans.

PurePath Volume Controls
