INSTALLATION AN OPERATIONS:
The Input Attenuator switches allow for a wide range of
signal levels and the Input Link jack allows for tapping
off of your signal chain. The Ground Lift switch lets you
totally separate the input and output signal grounds,
when appropriate, to isolate two systems, thereby
reducing hum and ground-loop noise.
What further sets the Xdirect apart from other “active DI”
boxes are its extended features and versatility.
We have added a switchable low pass Filter that cuts
out all very high frequency interference. This Bessel
filter on the input is placed out of the audio range and is
primarily intended to reduce radio frequency
interference before it gets into the main system. The
filter is also very effective in reducing any digital
computer noise artifacts when using the Xdirect as an
interface between a computer based audio workstation
and your monitors.
A Phase Invert switch, while not normally included with
your run of the mill D.I. box, has been added to allow
you to switch signal polarity right at the source. This
feature is especially handy when you are combining a
direct tap with a microphone feed in the mix.
The Xdirects active circuitry is powered by an internal
9volt battery, when external power is not available. In
this mode it draws 3.5 ma which should give you more
than 250 hours of operation off of a new battery. If
