The Bose Community Forum was launched at a time when robust online support was not available for Bose customers. Over the past several years we have added new online service channels that provide a more interactive and complete digital experience. Additionally, we have enhanced the My Bose Account capabilities to deliver a more personalized and self-service experience. As a result, Bose has made the decision to close Community Forum for Consumer electronics products on September 30th. The Bose Pro portion of the Community will still operate as usual.

Please visit our support homepage to experience one of our many other digital service channels or simply use your Community log-in credentials to sign in to your My Bose Account to view your orders and view support options.

Thank you to all who have contributed and benefited from interacting in our Community. We look forward to continuing to serve you online.

LI Pro32/Sub2 Volume Level and Noise

It seems that I cannot turn up the input volume on the L1 Pro base past 9:00, or three lighted bars. 

If I go beyond that I get considerable white noise that increases as the volume increases. This occurs whether I have anything connected or not. It is slightly less noisy if the Music EQ setting is used. Our normal use case is connecting a mixer for a band.  Is three bars the maximum input volume?


Re: LI Pro32/Sub2 Volume Level and Noise

Hi LarryR!

Professional PA systems inherently have a higher noise floor than other speakers and home electronics. As the largest portable PA system, the Pro32 will have the highest noise floor. This may be most apparent when standing closer to the system, but will likely be much less noticeable once the system is set up for use at a live venue.

Make sure the output from your mixer is at a loud, healthy volume without clipping when going into the L1 system, to ensure your signal to noise ratio is the best it can be. This article may also prove useful for more information on gain staging.

Hope this helps!
