The HPO module features two audio inputs for the left and right stereo channel. If you want to listen to mono material, just patch the left connector only. Thanks to normalization, the signal is automatically doubled to the right channel. The level of the actual headphone amplifier can be adjusted via a potentiometer. A stereo output emits the results.
