==== 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.


NOTE: these will be moved to a new page when there are more of them.

==== Can a stereo signal be used with the analog input?  ====
<section begin="Stereo Source to Power Stand Analog Input" />


=== Gain Staging  ===
'''A ¼ inch Tip-Ring-Sleeve connector carrying a stereo signal should not be used with the analog input on the Model II.'''


Q: What is the proper method for setting the gain on a Model II power stand when connected to an analog source?
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.


A: While playing your instrument or audio source as loudly as you would in performance, adjust the trim level on the power stand until you see the LED go from yellow to red. Then back the trim level off until the signal LED is predominantly yellow with brief peaks into 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.  


=== Stereo Source to Power Stand 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.


Q: Can I run a stereo signal with a ¼ inch Tip-Ring-Sleeve connection to the {{Model II}} Analog Input?
[[Image:TRSfromStereoRCAModelII.png|600px]]


A: This is not recommended, and may result in very little sound.

[[Image:18stereoTo14stereoModelII.png|600px]]


:A bit more clarification - if you plug a true stereo TRS into a model II analog input you'll actually get VERY little sound.


:Since the analog input is balanced, it actually will subtract the Left from the Right (this is how balanced inputs have less noise...I could explain more if anyone is interested). For many recordings, this ends up being very little sound.

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?
 
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.
 
: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.
