Author Topic: CP-500 Subwoofer Output Adjustment Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 06-12-2018 04:25 PM                     Can anyone share the steps taken to avoid all of the 500's request for mike readings allowing me to pull up the subwoofer output screen? The screen shows an error based on "Input Too Low". I've always heard there's a back door that will allow a subwoofer adjustment the same way the screen channels are adjusted. I've followed instructions from the Installers Manual sections 5-12 to 5-14 but the "input Too Low" continues to show up.  |  IP: Logged Allan Lyman Film Handler Posts: 35 From: COPENHAGEN, S /copenhagen,denmark Registered: Apr 2016 posted 06-14-2018 03:31 AM                     Hi Don when the CP500 wants you to input the calib rated SPL,you turn it all the way down.I think it stops at 45dB,if I remember correct,then it will work,and not come out with the input too low statement Alan  |  IP: Logged Magnus Eriksson Expert Film Handler Posts: 121 From: Stockholm, Hägersten, Sweden Registered: Jan 2011 posted 06-14-2018 09:22 AM                     First time I got stuck there I hooked up a standard microphone (I think it came from an old telephone answering machine in the booth) to the CP500 and made a lot of noise with my mouth. Then I was allowed to continue :-)  |  IP: Logged Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 06-14-2018 09:47 AM                     Allan you win the daily double.

Now we all know how to beat the system.  |  IP: Logged Allan Lyman Film Handler Posts: 35 From: COPENHAGEN, S /copenhagen,denmark Registered: Apr 2016 posted 06-15-2018 03:11 AM                     Hi Don glad I could help Alan  |  IP: Logged
