FAQs

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

Analog Input

The Analog input is a ¼ inch balanced input jack. There is a trim control.

Stereo Input to to Analog Input?

Q: Can I run a stereo signal with a ¼ inch Tip-Ring-Sleeve connection to the L1 Model II Analog Input?

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

MikeZ-at-Bose [1]

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.
Just wanted to clarify - you cannot 'get through the gig' this way if you're a DJ or needing to run prerecorded music.

Analog Input for Second T1 ToneMatch Audio Engine

The L1 Model II will support two T1 ToneMatch Audio Engines. See T1 ToneMatch™ Audio Engine / Connections to Model II for details.

Start Up / Cycle Time

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.

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

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.

Whatever you do, please don't cover up the fan port.[3]

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

Height

The fully assembled height of the L1 Model II is 84 inches. (213.36 cm)

Clearance required to assemble is approximately 87.5 inches. (222.25 cm)

Input Panel

L1™ Model II 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

If you want to record using USB without using the L1 Cylindrical Radiator® loudspeaker or B1 Bass Module ...

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.[4]
