L1 Model II

Let's talk about the L1® Portable Line Array Systems

Using proprietary Bose® technology, L1 systems combine  PA and monitors into a single, highly portable unit. The  loudspeaker can be positioned behind or to the side —and you hear what the audience hears.

Highly portable PA and monitor combined for solo performers, DJs and general-purpose use. Fixed vertical control with 180° horizontal coverage Reduced vulnerability to feedback.

Three systems to choose from (Compact, Model 1S, Model II)
Two passive bass module options (B1 or B2)
Consistent coverage and tonal balance, portability and easy setup.

Out of nowhere last week the bass bin of my L1 has begun to buzz loudly, can you inform me of any possible fixes... can't afford another! 

Pete posted:

to clarify, the buzz/hum is there when the unit is plugged into an isolated source, on it's own or with a multi socket adaptor with other units.

Does the buzz happen when there is nothing connected to the L1?

If not, then connect components one at a time until the buzz returns. Then see: Ground Loop


Does the buzz happen in different locations? (Different buildings?)

If not, then you may have an issue with line noise in the location where this is happening. Please see: Line Noise

Please tell us more about the buzz. Can you describe or record it?
