=== ToneMatch® Port ===


== Start Up / Cycle Time ==
For connecting the {{T1}} to the {{Model II}}.


The model II takes a few seconds to fully boot up and then turn the audio on. Make sure you are waiting the right amount of time.
The port sends electrical power to the T1 and accepts digital audio from the T1.


Secondly, if you do reset the system for some reason, be sure to wait a full two or three seconds between turning it off and turning it back on.

=== Fan Noise ===
Close up
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 PS2 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.
[[Image:ModelIIToneMatchPortCloseUp.png|ToneMatch® Port on the Model II close up]]


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>
The connecting cable has a male Ethercon connection at each end that looks like this.  


There is a Firmware Update that addresses the fan behaviour. See: [[L1™ Model II Power Stand Firmware Updates#Fan_Behavior]]
[[Image:EtherconMale.jpg]]


== Height ==
For details about the cable see: [[T1_ToneMatch%C2%AE Audio Engine#Cables|T1® Cables]]
The fully assembled height of the {{Model II}} is 84 inches. (213.36 cm)


Clearance required to assemble is approximately 87.5 inches. (222.25 cm)
<section begin=AnalogInput />
=== Analog Input  ===
The Analog input is a ¼ inch balanced input jack. Do not connect a stereo source to this input.

* [http://www.bose.com/controller?event=VIEW_STATIC_PAGE_EVENT&url=/musicians/products/l1_model2/product_l1_m2_1b1_t1.jsp#specifications interactive view of the input panel]


* Analog input, trim control and signal/clip LED
: Line-level analog input accepts 1/4" TRS phone cable. Can be used for instruments or other audio sources like DJ mixers, MP3 players, computers or DVD systems. Trim control lets you adjust the level of analog input signal. Signal/clip LED indicates status of analog input signal.
* Bass module out
: Delivers amplified bass output signal to one or two B1 bass modules. L1 system automatically adjusts equalization appropriately when bass modules are connected.
* ToneMatch™ port
: Digital audio and power connection for ToneMatch audio engine. Use with included ToneMatch cable.
* Bass line out
: Post-DSP bass signal output. Accepts 1/4" TRS phone cable. Use to connect PackLite® amplifier with up to two additional bass modules. Can also be used to connect powered subwoofer or additional amplification system.


== No Speakers Attached ==
==== 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.


If you want to record using USB without using the {{L1 CR}} or {{B1}} ...
[[Image:Model II Analog Input Trim.png]]


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&f=3976055944&m=2261013484&r=7911053484#7911053484 Using the L1™ Model II Power Stand without any speakers attached]</ref>

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


== Articulated Array&reg; ==
'''A ¼ inch Tip-Ring-Sleeve connector carrying a stereo signal should not be used with the analog input on the Model II.'''
[[Image:ModelIIArticulatedArray.png|L1&trade; Model II Articulated Array&reg;]]


== Identifying this Model ==
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.  
* Retractable legs
: Provide stability for streamlined L1 Model II power stand and loudspeaker. Four retractable legs fold out of power stand simultaneously for quick setup and compact transport. Small footprint also frees up room on tight stages.  


* Light weight (23.7 lbs (10.7 kg)
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.  


== Compatibility ==
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.
Compatible with
* L1 Model II Cylindrical Radiator® loudspeaker
* [[T1 ToneMatch™ Audio Engine|T1 ToneMatch™ audio engine]]
* {{B1}}
* {{A1}}

== 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>
