Limiter
On the Bose® Pro Portable PA Community you will read about "compression" when the L1™ is operating at high volume.
Hilmar-at-Bose tells us:
- There is no actual compressor. The only dynamic processing is a protective limiter. That should only kick in, when you are hitting it real hard.
- This limiter is not per-se frequency dependent, but there are independent ones for the L1 and B1 and they are tuned a little different.

- Model II limiter
- The limiters threshold is from -50.0dB to 0dB. A limiter is a type of compressor to limit the level of a signal to a certain threshold. A limiter will almost completely prevent any additional gain above the threshold. Limiters are used against signal peaking (clipping). They prevent occasional signal peaks which would be too loud or distorted.
