This makes it easy to properly adjust the gain for each input module while efficiently using the rest of the system in terms of performance and headroom. Figure 7. Block Diagram of 1707C/1715C Mixer/Power Amplifiers The mixer/power amplifier then sums the signal at the wiper of each input channel level control into a true virtual ground summing node or bus. The summing amplifier has eight input channels — input channels one through six on the front panel, tone generator output, and the link in

The 1590E provides 200 watts of power at less than 1% total harmonic distortion (THD) from 50 Hz to 12 kHz, and has a frequency response of -1 dB from 20 Hz to 20 kHz at one watt output. Output transformer taps provide connections for 70.7. 100. 140 and 200 volt line distribution systems. The 1590E features silicon solid-state circuitry, a switchable high-pass filter for use in speech systems, input connections for high impedance devices and for 150/600 ohm or 15,000 ohm balanced inputs, fail-s
