Short circuit resistant, the rugged output
circuits can drive full signal levels into 600
ohm or greater loads.
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
process of getting maximum audio
performance. After checking with person-
nel 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 refer-
ence 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 match-
ing is accomplished 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!
