Electronic or Transformer Balanced Inputs and Outputs.
All Inputs and Outputs Individually Adjustable.
The Models 5117, 5117T, 5217, 5217T audio
distribution amplifiers are designed for use
in professional audio systems.
The application of the ADA's is found in public
address systems, communication systems, back-
ground music systems, recording systems. and
broadcast systems.
Each of the four models offers one (1) input and
seven (7) output configurations. The 5217 and
5217T offer two identical 1 x 7 sections.
The Models 5117 and 5217 have state-of-the-art
electronically balanced input(s) and outputs. The
5117T and 5217T have transformer isolated
input(s) and outputs.
The input gain stage(s) on all four models is
adjustable from 0 to 20dB of gain. Each of the
outputs has independently adjustable gain, from
infinity to 20dB of gain. Adjusting the level of any
output section does not effect the settings of any
other output. Adjusting the input stage level will
effect all of the output level settings in that
section. The 20dB of gain available at the
input stage should be used before the gain of
the output section is utilized.
Using the output gain before the input gain has
been exhausted, may result in lower headroom (less
level increase before clipping). All units are shipped
from the factory with gains adusted to unity, into a
600 ohm load.
The power supply section of all four models has
been designed to achieve the lowest possible
noise and hum specifications. The AC transformer
is a UL recognized wall mount unit. Designing
the transformer in this manner eliminates the AC
field inside the chassis, and results in greatly
improved noise and hum figures.
The power supply section also includes a rear
mounted fuseholder, a front mounted power on
indicator (green LED), and a ground lift switch.
The switch is used to disconnect the audio
amplifier ground from earth ground, if
necessary. In almost all systems, the units will
achieve best results with the ground lift switch
in the ON position.
Each of the four models requires only a single
unit of vertical rack space. The choice of single
or dual units provides extreme circuit density in
a minimum of rack space.
