What does the "FULL RANGE" option do on the back of the GKCX series cab?
Pretty sure that switch toggles the cabinet between bi-amp and full range operation. GK RB series amps can do the bi-amp thing as well as running in full range mode.
What's the difference between bi-amp and full range?
In biamp mode, your GK head controls the tweeter volume (the RB series that have the tweeter amp in them)
In full range mode, you control your tweeter volume on the cab - for when you want a tweeter but don't have the GK amp that has the tweeter amp incorporated.
I use it in biamp mode with non GK heads because that way I completely bypass the tweeter (I hate tweeters).
In addition, I think the tweeter amp bypasses the Boost circuit so the tweeter won't sound harsh. The woofers are much friendlier with the Boost growl.
Yup, that is true. One of the advantages of the GK biamp function is that the tweeter signal goes clean.
Still, I really really dislike the tweeter in my GK NEO 412. Didn't hate it so much in Ampeg 410HLF (didn't sound so harsh, but more mellow) but that's probably because without it, that cab is a muddy mess (and IMO, it's still a muddy awful mess).
It is simply an on/off switch for the tweeter. These cabs don't do bi-amping.
It's not an "option", the speakon and jack inputs are both labeled "Full Range" and in between the inputs there's an on/off switch for horn. So yeah, no bi-amping with CX's.
Yeah, I feel so stupid hahaha thanks for the kind answer, sir.
Not all GK heads support the biamp, or Horn Management System.
The RB ersies heads do, and, the big Fusion does. The MB series heads do not.
The 400RB IV also does not, none of the 400RB series do. They are the exception to the "RB" rule.
