DESCRIPTION

The Altec Lansing 1707C/1715C Mixer/Power Amplifier is a six channel user-configurable mainframe amplifier. By selecting from the large array of system component options, the 1707C/1715C can become a six-in/one-out microphone mixer/amplifier or a one-in/six-out distribution preamplifier.
The basic mainframe combines a fully protected 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 mainframes 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 connector 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 mixer/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.
