dynamic out of
control - no more
The
extremely short signal flow within the Vari Tube
Compressor is completely built with tube technology. In
addition to input and output transformer the signal only
runs through two tube amplifier stages. These elements
provide signals with a very sophisticated and special sound
which already polished a lot of recordings. The particular
Vari Tube circuit enables you to break completely new
ground in compression. The signal gets compressed without
any undesirable side effects and receives more depth and
power. The smooth transition from linear amplification to
compression ensures a well-balanced sound.
Setting for
the desired programme is made by separate Attack- and
Release-controllers. The compression itself is executed by
the Input-controller. The more input the more compression -
it‘s as simple as that. The big, illuminated VU-Meters can
be switched from output level to gain reduction.
You want to
use the Vari Tube Compressor for single signals, too?
No sweat! With the Link-switch you can either separate the
channels both or link them for stereo processing. For this
reason, during recording you can work on two separated
signals and then change to stereo mode for mixing. For
instance at the output of the Tube Summing Amp - a perfect
combination.
What does Vari
Tube actually mean?
The operating
point of a tube is set by negative DC voltage (the so called
Bias). Usually this point is fixed. However, there are
special tubes where the internal amplification can be
controlled via the Bias. Such tubes are the central element
of the Vari Tube Compressor.
From the input
signal a special control signal (Sidechain) gets extracted
which controls the Bias and thus the amplification of this
circuit. Within it also the time parameters “Attack” and
“Release” are integrated. This signal then gets routed to
the Bias of opposite phase amplifier stages. Crucial here is
the exact clocking of the units both. To comply with these
demanding requirements the tubes have to be manually
selected. Only about one from fifty tested tubes fulfils
these high standards. This Vari-Tube-technics was already
used for the legendary Fairchild 670 and is still state of
the art for musical signal compression.
With the Vari
Tube Compressor you compress your sound signals without any
disturbing side effects! |
