PATCHBAYS
Our Patchbays Now Feature the New
Professional Punchdown Terminal (PPT)
Our Patchbays Have Just
Rounded A New Corner
Actually, the corners we rounded
belong to our patchbays’ revolutionary,
new Professional Punchdown Terminal
(PPT), making it perfectly compatible
with the industry standard. We realized
that achieving a new industry standard
meant we couldn’t cut any corners to
get there.
split-barrel design and a more rugged,
thicker housing to minimize the
impact of repeated punchdowns.
The split-barrel design eliminates
the problems associated with the
old “V-shaped” terminal designs.
The PPT design distributes pressure
evenly across both sides of the
terminated wire, causing improved
wire retention plus more reliable
connections. The serrated teeth in
the plastic housing firmly grip the
wires, which also greatly improves
wire retention. With the PPT, multiple
wires can be terminated to a single
contact, and a wide range of wire
gauges can be used.
All Switchcraft audio patchbays incorporate heavy gauge materials and our high quality nickel-plated, steel framed
jacks. Gold-plated, crossbar contacts come standard!
