ZBIT
stands for Zen Balanced Input
Transformer. It's purpose in
life is to take the XLR balanced
output from a source component or
preamplifier and convert it to an
unbalanced RCA jack that can feed your
unbalanced audio component.
The output from the RCA jacks is fully
adjustable from 0 to anywhere between
3 & 10 volts ~ basically the full
output voltage of your balanced
component. It is designed to be
adjusted relative to the volume
control on your preamp or amplifier if
you're not using a preamp.
Running the ZBIT adjusted high and the
volume control on your preamp or amp
low sounds completely different than
running the ZBIT adjusted low and the
amp or preamp adjusted high. This
large difference in sound lives in an
infinitely adjustable window between
the two extremes giving you great
control over the magic spot where it
will sound best.
The ZBIT is ideal for low powered amps
of all types, or high-powered amps
that either have a gain control (input
level) or use a preamp.
The ZBIT is also ideal for taking
advantage of balanced cables over
longer distances. While cable quality
is a factor, it is far less of a
factor with XLR cables than with RCA
cables, so when we need to run over 6
feet, we use balanced cables that feed
a ZBIT located 1 meter away from the
amp or preamp. From the ZBIT we use,
the best 1 meter interconnects we have
to feed the amp or preamp.
The transformer in the ZBIT is made in
the USA by Jensen and has a bandwidth
from 10Hz ~ 95kHz. It is
unmolested by Zobel or RC networks
leaving it to do what great
transformers do.... impart shimmering
liquid highs with a massive
improvement to dimensionality.
