=== Overview ===
{{Model 1S Input Output Panel}}

=== ToneMatch® Port ===
For connecting the {{T1}} to the {{Model 1S}}. 

The port sends electrical power to the T1 and accepts digital audio from the T1.

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

For details about the cable see: [[T1_ToneMatch%C2%AE Audio Engine#Cables|T1® Cables]]


=== Analog Input  ===

[[Image:Model 1S Analog Input Detail.png]] 

The Analog input is a ¼ inch balanced input jack. 

==== Analog input trim (volume, or gain) control  ====
There is a trim control for the analog input.

[[Image:Model II Analog Input Trim.png]]

# Set the '''Trim''' control on the power stand to the 0 (zero) position.
# Connect the audio source to the Analog Input
# Adjust the volume of the audio source to the maximum output without distortion.
# While playing the source, increase the '''Trim''' level so that the '''Signal/Clip''' indicator glows green or yellow.
# If the '''Signal/Clip''' indicator glows red, decrease the '''Trim''' level so that it glows only green or yellow.

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

'''A ¼ inch Tip-Ring-Sleeve connector carrying a stereo signal should not be used with the analog input on the Model 1S Model II or Compact Channel 2 &frac14; inch jack Tip-Ring-Sleeve 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. 

The analog input 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 1S, Model II or Compact Channel 2 &frac14; inch jack Tip-Ring-Sleeve 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.

== Start Up / Cycle Time  ==

The Model 1S takes a few seconds to fully boot up and then turn the audio on. Make sure you are waiting the right amount of time. 

If you do reset the system  be sure to wait a full two or three seconds between turning it off and turning it back on. 

== Height  ==

The fully assembled height of the {{Model 1S}} is 79.4 inches. (201.93 cm) 

Clearance required to assemble is approximately 84 inches. (213.36 cm)

*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 or one {{B2}}. 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.


== No Speakers Attached  ==

If you want to record using USB without using the {{L1 CR}} or {{B1}} or {{B2}}  ... 

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>
