=== Analog Input  ===
The Analog input is a ¼ inch balanced input jack. Do not connect a stereo source to this input.

==== Analog input trim (volume, or gain) control ====
There is a trim control for the analog input. Turn this off (fully counter-clockwise) unless you have something connected to the Analog Input.

==== Properly setting the analog input trim (volume, or gain) control  ====
'''A ¼ inch Tip-Ring-Sleeve connector carrying a stereo signal should not be used with the analog input on the Model II.'''


There is a trim control for the analog input.
Even though a ¼ inch Tip-Ring-Sleeve connector can carry a stereo signal this is not how this physical connection is used on the {{PAGENAME}} Power Stand.  


With the audio on the input signal at or near its most intense, adjust the trim level on the Model II analog input until the LED begins to turn from yellow to red. Then reduce the trim level until the signal LED is predominantly yellow with only brief changes to red.  
The analog input on the Model II is balanced, and will therefore subtract the Left and Right signals on a stereo cable and you will hear an L-R (Left minus Right) signal in the Model II.  


==== Can a stereo signal be used with the analog input?  ====
You cannot 'get through the gig' this way if you are a DJ or if you need to run prerecorded music or have stereo inputs.


<section begin="Stereo Source to Power Stand Analog Input" />
[[Image:TRSfromStereoRCAModelII.png|600px]]


In audio, a ¼ inch Tip-Ring-Sleeve connector can carry a stereo signal.

Q: The fan in the Power Stand comes on when I strike a chord on my Guitar. Is this normal? A: Your unit is functioning properly - no problem.  


The fan in the Model II Power Stand comes on when the input signal level goes over a certain limit, regardless of what the internal temperature of the unit is. That way, the unit never gets too hot to where a fan needs to be on constantly.

== Noise During Shutdown ==
Q: When I turn off the Model II there is sound like flatulence. Is this normal?


Whatever you do, please don't cover up the fan port.<ref>MikeZ-at-Bose [http://bose.infopop.cc/eve/forums?a=tpc&f=7521050644&m=8071027174&r=7091047174#7091047174 Model II Fan Noise]</ref>
A:
:Over a year ago we implemented an improvement which allowed the system to better withstand extreme low voltage conditions caused by brown outs etc. Units produced prior to this change were quieter during the power down sequence.  


There is a Firmware Update that addresses the fan behaviour. See: [[L1® Model II Power Stand Firmware Updates#Fan_Behavior]]
:Note: This noise is only present when the system is being turned off following use. For instances where this subtle noise is objectionable you may remove the Cylindrical Radiator loudspeaker and disconnect the Speakon cable of the B1 before powering down the system.
 
:For anyone that is experiencing noise during power down we want to assure you that your system is working properly. Also, there is no reason for customers with older power stands to be concerned with upgrading as any potential issues would have surfaced by now. <ref>Neil-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/76010377/m/948107242?r=207101852#207101852 Modell II Shutdown Noises August 3, 2009]</ref>

You can certainly run the L1 with all, some, or none of the speakers connected. With no speakers connected it will happily serve as a big power supply for the T1. You are in no way risking damage to the unit by doing this.<ref>MikeZ-at-Bose talks about [http://bose.infopop.cc/eve/forums?a=tpc&amp;amp;amp;amp;amp;f=3976055944&amp;amp;amp;amp;amp;m=2261013484&amp;amp;amp;amp;amp;r=7911053484#7911053484 Using the L1™ Model II Power Stand without any speakers attached]</ref>
