Connection – simple mono audio input Vol. Bass Terrible connection with mono output

You can also use this setup, which is commonly applied in Pr. SRS single volume/bass/treble amplifiers. In this design, a single volume control (taken from either the right or left channel of the BT module) is integrated into the mono volume/bass/treble section. The processed mono output is then split into left and right channels (L+R) and fed to two 4440 ICs on the S734 board. As shown below.
