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 I707C/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. 1707С/1715С Specifications (cont'd) Continuous Average Power: 1707C: 1715C: Maximum Midband Output Power: 1707C: 1715C: Power Bandwidth: Direct Output: Intermodulation Distortion: Direct Output: Damping Factor: Direct Output: Rated Output Level: Direct Output: 1707C: 1715C: Preamp Output: Transformer Output: 1707C: 1715C: Equalization: Bass: Treble: Compressor/Limiter: Threshold: Compression Ratio: Release Time: Tone Generator: Tones: Control: Level Adjustment: Protection System: Amplifier: Load: Front Panel Controls: Input: Compressor/Limiter: 75 watts 150 watts (Ref. 1 kHz at 1% THD) 100 watts 175 watts (Ref. 1 kHz at rated output) >20 Hz - 20 kHz (SMPTE 4:1) <0.1% at rated power >40, 20 Hz - 1 kHz (Ref. 1 kHz) (unbalanced) 24.5 Vrms/8 ft load 24.5 Vrms/4 ft load (unbalanced) 0 dBm, 600 ft min. load (balanced) 17.4 Vrms/4 ft load 25.0 Vrms/8 ft load 70.7 Vrms/66.6 ft load 25.0 Vrms/4.2 ft load 34.6 Vrms/8 ft load 70.7 Vrms/33.3 ft load (Shelving type) ±12 dB at 100 Hz ±12 dB at 10 kHz Feedforward Topology -20 dB to +20 dB Continuously variable (Ref. 100 mVrms on Link input) 1:1 to »:1 Continuously variable 50 msec to 5 sec.
