30 Full active operating modeWith the use of control 30 the amplifier is operating infull active mode. Set the switch on position 2. In thiscase the frequencies of input A and B (only this can beused in full active mode) are set for channel A and B.The lowpass of the signal's adjusted frequency with control22 for channel A and B will be transmitted to channelC and D, regardless of switch 18 position (HP/ Lin/TP), no matter if channel A and B are used as highpass,full range or lowpass, the signal is always transmittedas lowpass to channel C and D. Adjust the desired frequencyof the transmitted signal with control 22. Due tothe transmission of lowpass to channel C and D it is possibleto build a bandpass with a bandwidth of 15 Hz upto 7 kHz.
