Audio Input of the Sound Generator End-stage is a stereo 3.5 mm jack. This input receives stereo signal from the sound output of the PC. The control program can use the advantage of the stereo sound capability of the PC. On the left and on the right channel two independent sound samples can be generated. After receiving the stereo signal from the PC, they are mixed together in the Sound Generator End-stage and amplified together as a mono signal.
The volume control of the Sound Generator End-stage is not usual. The reason, why it was designed such an expensive way was the repeatability. You can calibrate the sound pressure level of the whole acoustic system (source of sound, amplifier and loudspeaker) once and you can reproduce the calibrated situation with the extremely precise scale of the volume control potentiometer any time.
A suitable wideband loudspeaker is provided as an accessory.
