I have a question regarding my DJ sound system.  I've been using a DBX 266XS compressor with my system for many years, and am now wondering how necessary it is to use with my pair of F1 812's and a pair of subs.  I do crank it loud at bigger events (school dances, etc.), but is the compressor simply unnecessary overkill with the F1's ability to protect itself?  Or is a little bit of compression helpful to protect it?

Hi Tony,

Thank you for joining the Bose Portable PA Community.  Welcome.

This is an interesting question.

The F1 Model 812 is an integrated system. Every stage and component was engineered to optimize the signal chain. This is different from using separate components (signal processors, power amp, loudspeakers).

"Or is a little bit of compression helpful to protect it?"

If you were to use a compressor, you'd need to use a hard-limiter to offer real protection. See: These discussions: Using Compression as Limiter on FOH, How to use a compressor/limiter for PA speaker protection and Loudspeaker Protection

You don't need a third party device in the signal chain. You can trust the limiters in the F1 Model 812 and F1 Subwoofer to protect the themselves.


Thanks for the quick reply, ST.  So you're saying I'm essentially wasting rack space with the compressor?  I don't use the OverEasy function, instead I keep it on AUTO mode, which is a "hard-knee" setting.  My main concern is playing music with heavy bass (rap, hip-hop) that I've always feared could potentially damage my speakers at high levels.  Again, I've used it for years, dating back LONG before I bought my F1 speakers/subs back in January, and the compressor just stayed rack mounted in my system.  I'm just wondering how well it's actually protecting them?  If it's not needed, I would likely just un-rack it and not bother with it.

Does anyone else use a compressor with the F1?

Hi Tony,

The F1 Model 812 and F1 Subwoofer have built-in limiters to protect the circuitry and the drivers.  If you prefer to use a limiter to process the signal before it gets to the F1 Model 812 and F1 Subwoofer, that's fine. I can't comment on how effective your dbx 266xs might be for added protection.

Let's see if anyone else ideas about this.
