The Model 80’s architecture precludes the
need for individual output-level trim poten-
tiometers. With the input signal calibrated
using the ExactCal section, the eight
stereo outputs use 1%-tolerance compo-
nents to provide precise –10 or +4dBu
outputs.
Audio Performance
The Model 80 is the result of exacting
circuit design combined with the latest
state-of-the-art components. Like all
Studio Technologies products, the Model
80 has survived tough listening evalua-
tions by industry professionals. These
veterans had the “ears” to guide us in
achieving the right performance. The
outcome is a product that achieves
sonic excellence.
Design Philosophy
Most audio distribution amplifiers contain
a level trim adjustment on each output.
After careful study Studio Technologies’
concluded that these adjustments con-
fused, and often interfered with the pro-
cess of getting maximum audio perform-
ance. After checking with personnel in the
field, it became clear that what is desired
in virtually every distribution-amplifier
applications are multiple audio outputs all
operating at a standard reference level.
By implementing the ExactCal system, the
Model 80’s internal operating level can be
easily calibrated to match the input signal.
Once this input level matching is accom-
plished the eight stereo outputs can be
individually configured for a –10 or +4dBu
nominal operating level. In conclusion,
output trim pots are not included on the
Model 80 for the simple reason that better
audio performance can be achieved
without them!
