Operation
Screw grounding connection when using a turntable.
If a CD player with a very high output is used and the input recording level can exceed 1Vrms there may be a
slight digital noise and distortion.
If the input signal level is too high the indicator LED will change from Green to Red, to set the correct level rotate
the VR anticlockwise until the indicator LED reverts back to Green.
The level is now suitable for recording.
If the output of the AC-1 is connected to a mains earthed mixer, an earth loop may be generated.
