T1 power supply hums with other amplifiers

Timbass ·
Irrespective of location (to eliminate mains hum from other sources) tests give the following: Bass with ordinary mag pickup - plugged directly into any mixer or amplifier = no hum. Bass plugged into T1 fed input/output from L1 Model II via its ethernet cable = no hum on any outputs. Bass plugged into T1 fed from T1 external power supply = hum, on all outputs including USB, irrespective of what amplifier it is feeding or none. Even with no outputs connected, the hum level can be seen on T1...

Hi Timbass, It sounds like you've done everything possible to isolate the issue. I agree. It's probably a fault in the T1 Power Supply. If the T1 Power Supply is less than 2 years old, it may still be under warranty. You'll have to contact Bose in your location to see if you are covered. If that isn't applicable, then I'd go to an authorized Bose dealer and test the T1® with a new T1 Power Supply. If that works, buy it. I'm sorry that I don't have better news.

Hi WirelessDJ, There were no detailed specifications at the link you provided. I didn't see that there's a variable low-pass filter. I did some digging and found more specifications here: http://www.daytonaudio.com/ind...oofer-amplifier.html . Does the powered speaker have a line level output? ST

B1 and B2 Amplifier

WirelessDJ ·
Has anyone ever used a B1 or B2 with an external sub amp i.e. like this one https://www.amazon.com/Dayton-Audio-SPA250-Subwoofer-Amplifier/dp/B0070Z81MW/ref=pd_sbs_23_3?_encoding=UTF8&psc=1&refRID=J9ZMG7BS3BHTX8F3DFKE Would like to be able to use my subs with other speakers

Yes, the active speakrs have standard XLR output, mono, full range, line level. This cheap amp does have a 40-180 hz filter. Theoretically it should work

I considered the packlite but the packlite does not have a low pass filter or any adjustments. I need something that can take the signal from a powered speaker then send to the B1 or B2

By the way, I am not recommending that this is a good product. Just used as an example.

Hi WirelessDJ, Bose makes the PackLite® Power Amplifier Model A1 specifically to be used with B1 and B2 bass modules. This is equipped with a proper Speakon connector to match the B1 and B2 bass modules. It also has a balanced input and comes with the appropriate cable for use with the L1® Model II Bass Line Out. I strongly recommend reading Kyle's introduction to the PackLite® to fully understand what it does. If you want to use a different amplifier then it should have specifications...

Re: Problem with Base/Amplifier

Hi Anthony, Thank you for joining the Community. I'm sorry that you are having trouble with your L1® Model II. Known Issue? IF... You connect a mixer to the L1® Model II Power Stand using the Analog input AND you are you using a 1/4" Tip-Ring-Sleeve cable AND you are sending a stereo signal to the Analog input You can get very strange results, often like what you've described. because that input is a BALANCED MONO input. The Left and Right sides of the signal will tend to cancel each other...

Problem with Base/Amplifier

Anthony Cooley ·
Does anyone know of any known issue with the L1 Model II base/amplifier that causes loud distorted sounds and little or no output from the source? Have tried different cables/sources and swapped in another base which worked fine. How much would repair cost and where would it need to be sent to? Anthony Cooley

Electrical sparks out of the base/ amplifier unit

stepoch ·
Hi I just received my L1 Model 2 units [2no.]. I am having a problem with one of them. when i plug it into power, electrical sparks fly out of the vent of the amp unit with pops and some smoke! i quickly turn off the unit hoping it would be sorted with a reset. This has kept happening now for 3 times. I do not know what the problem is or if its a factory error. I live in Uganda and had the system shipped to me. It would be costly shipping it back. I don't know what to do now. I am just...

Re: Electrical sparks out of the base/ amplifier unit

perhaps a short circuit. if you purchased a US system with 110 volts there will appear problems with voltage & plugs. as i know, Uganda will use 240 voltage with special plugs like Great Britain https://www.welt-steckdosen.de/uganda/

Hi True our voltage is 240. I did use a step down voltage adapter for this. I actually purchased 2 Bose l1 model 2 systems. The first one works well without an error on the same voltage adapter
