What's New in PBX DSP8

2.1.0

July 18, 2026

update: fixed bugs

User reviews

Great, except…

The app and hardware are great and do what they’re made to do, but two issues: 1) when changing from one page to another on the eq, one frequency gets missed between the pages somehow on of these got put at like +10 and now I can’t bring it back down. 2) there is no hand-holding in this app, and it is clear they want it that way. I think every page of the hardware manual says to stop and contact a pro if you don’t know what you’re doing, and the app feels the same way. No warnings, no tutorials. And if you click the help button? It takes you to the pdf of the hardware manual.

If you can manage all that, it’s pretty great.

Can’t find BT on my iPhone with the last software update

Can’t find BT on my iPhone with the last software update, iOS 18

Response from developer

Please update the app again to version 2.0.8 of the iOS software. This should resolve your issues as iOS18 created a bluetooth connection issue. This has now been resolved.

Saving setting is a mess

Saving settings is easy however making the PBX to run them as intended is another story. After powering down and powering back up a few times the unit actually goes back to old settings. I’ve seen that happen a few occasions. When I load recently saved Settings for some reason, it does not make my front speakers run. I have to re-select the benchmark speakers a few times and the sound comes back. If you like to play around with Settings, this is not a good unit for that.
