DESCRIPTION

The Altec Lansing I700C Mixer/Preamplifier is.

asix channel use r-configurable mainframe preamp-
lifier. By selecting from the large array of system
component options, the 1700C can become a six-
in/one-out microphone mixer or a one-in/six-out
distribution preamplifier.

The basic mainframe has six ports which can
be input or output. When configuring with Altec
Lansingss 1780A/AT or l781A/AT Programmable
Input modules, the mainframe becomes a powerful
six channel mixer. Multiple 1700C mainframes can
be linked together for situations where more then
six input/output ports are required.

Built-in features include a top panel trap-door
for easy access into the unit, compressor/limiter,
low and high frequencyshelving equalizers, muting,
remote volume control capability, and a tone gen-
erator which produces four different sounds.

Input Modules: The Altec Lansing 1780AI-
1780AT lnput module and the 1781A/1781AT
Programmable lnput module accept either mic or
line level signals through a wide variety of connec-
tor interfaces. Further detail on these modules is
given later in this document.

Output Modules: The Altec Lansing 1783 Line
Output module allows the user to interface with
otherprofessional equipment. Further detail on this
module is given later in this document.

The Altec Lansing model 1700C mix-
er/preamplifer 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.
