Firebox gain update
Just got a really informative response back from Chad at Presonus support about my -6db clipping/low gain issue with the Presonus Firebox:
Yes, the FB pre's are a bit on the low gain side, although they shouldn't clip too easily. Ã‚Â Unfortunately, if they don't provide enough gain with the digital boost engaged (and you may try disengaging it to help with clipping), you may want to couple them with the Blue Tube or use the Blue Tube with line in. Ã‚Â The BT has about 20db more analog gain than the FB. Sorry. Ã‚Â As I understand it, they had to make the FB in a way which was bus-powerable even under the most extreme conditions (daisy-chained w/ other FW devices, on laptops, etc.) which probably compromised the voltage that the preamps could run off of. Ã‚Â The BT gain circuit runs off of about 16v rather than the 6v or so that the FB runs from
That's some good information for your ass right there. Awesome support from Presonus.
Unfortunately the goal was to replace my Bluetube and Delta66 with a portable firewire thang. The Presonus Firebox would handily replace the Delta66, but replacing the Bluetube with a quieter preamp that doesn't go above -6db kinda blows. If I'm going to keep using the Bluetube, then I'm not sure why I'd pay a bunch of extra money for a device with preamps I never use on it. So much to think about.
