DESCRIPTION
The Altec Lansing 1707C/1715C Mixer/Power
Amplifier is a six channel user-configurable main­
frame amplifier. By selecting from the large array of
system component options, the 1707C/1715C can
become a six-in/one-out microphone mixer/amp-
lifier or a one-in/six-out distribution preamplifier.
The basic mainframe combines a fully protect­
ed 75-watt (for the 1707C) or 150-watt (for the
1715C) power amplifier with six ports which can
be input or output. Multiple 1707C/1715C main­
frames can be linked together for situations where
more then six input/output ports are required.
Built-in features include a trap-door on the top
panel for easy access into the unit, compressor/-
limiter, low and high frequency shelving equalizers,
muting, remote volume control capability, and a
tone generator which produces four different
sounds.
Input Modules: The Altec Lansing 1780A/-
1780AT Input module and the 1781A/1781AT
Programmable Input module accept either mic or
line level signals through a wide variety of connec­
tor interfaces.
Output Modules: The Altec Lansing 1783 Line
Output module allows the user to interface with
other professional equipment.
The Altec Lansing model 1707C/1715C mix-
er/power amplifier systems respond to most design
tasks with the ease and versatility of systems
costing much more. As a result, it is
the choice for
use in professional Installations requiring high
quality, flexibility in design, and low cost.
