Lives for gear


I would like to start using some of my "External Pre Amps" pluging them into my RME UFX interface. SHOULD I use the analog inputs that are on the FRONT of the UFX - OR - use the analog inputs that are on the BACK of the UFX ??? Which ones would be the BEST ones to use for the best audio quality??

Thanks in advance!

The front inputs are always going through the built-in pre signal path, even if you're not using the RME to boost the signal. So I'd say your best bet is to use the rear connectors, which are direct, unaltered line inputs (although you do have the option of specifying the reference level at -10 or +4). The rear inputs are all 1/4" TRS, so depending on your preamp you might need an XLR-to-TRS cable or adapter.

One other thing that's different between the front and rear inputs is that the 1/4" connections on the front combo jacks are unbalanced (even though it's technically a TRS connection), while the XLR connection is balanced. I guess they're expecting you'd be plugging instruments to the front jacks, which usually have unbalanced connections.

But you get better AD running through the front.

Advanced Parallel Conversion . The four UFX preamps are feeding not only four, but eight AD converters.
Try both - use your ears
