Parasound A 51 - Manual (Page 8)

MANUAL AND AUTOMATIC TURN ON-OFF OPTIONS
You can manually turn the A 51 on and off with its front panel On-Off button. It can also be triggered
to turn on and off automatically when your preamplifier, surround controller, or system controller is
turned on and off.
Manual On-Off from the Front Panel
If you want to manually turn on and off the A 51 at any time, you need to first select the Manual On-
Off option by placing the Auto Turn On switch (on the rear panel) to its middle Man (Manual) position.
Connecting an Active Audio Source for Automatic On-Off
If you want to automatically turn on the A 51 whenever music is playing (an audio signal is present),
choose the audio triggering option by moving the Auto Turn On switch to its upper Audio position.
What You’ll Need:
• An audio source that’s playing
Before Connecting
❑ Remove power to all the components in your audio system.
❑ Make sure the Auto Turn On switch on the A 51 is in its Audio (up) position.
❑ Set the Audio triggering Sensitivity adjustment knob on the rear panel to the desired level.
Start with the 12 o’clock position.

YOU SHOULD KNOW
Turn Off Delay in the Audio Mode
When the music stops, the A 51 will remain on for about five minutes. This delay prevents
unwanted turn-off during silent passages in music or during the pauses between tracks.
