AC/DC Output
AC and DC is accessed by the use of the optional CBL042 or
by using a stereo miniphone plug as shown in figure 4-5. The
DC output provides a voltage from the RMS detector that is
proportional to the sound level. The scale is 20.3 mV/dB. The
output voltage is 0-3 volts with an output impedance of 600¾.
The AC output gives an AC signal proportional to input signal
and can be Flat or A and C weighted. It is used to record input
signal to the Model 820 (note Appendix A for more details).
