Off option by placing the Auto Turn On switch (on the rear panel) to its middle Man (Manual) position.

YOU SHOULD KNOW
Turn Off Delay in the Audio Mode
When the music stops, the A 52 will remain on for about five minutes. This delay prevents
unwanted turn-off during silent passages in music or during the pauses between tracks.
