PXB is the AV audio professional’s trouble-shooting
toolkit. Being completely passive (no batteries or
external power required) and bi-directional, PXB can
match unbalanced and balanced audio sources, line to
mic levels, stereo and mono signals, and troubleshoot
hum problems – all in one versatile and rugged unit.
Having both phono and 3-pin XLR connections, the PXB
is the simplest way to interface unbalanced computer or
consumer audio signals to balanced AV sound systems.
The inputs and outputs are completely isolated in either
direction and by using the ‘Ground Lift’ feature where
required, hum problems can be easily cured.
