Set your source volume at a position between 6 o'clock and 9 o'clock, and leave it at this setting. Always use the AVA1210 volume control as a master main volume control. It has better electronics, higher signal to noise ratio and is more linear than any source unit volume control available. If engine noise is audible, check the ground connection on all units and in the audio system.
