Probably stupid question about the Audient ID22 inputs

[al_diablo]

I need to record something today from a portable turntable (built in preamp) and don't have much in the way of cables about. The outputs are RCA and I have RCA to XLR unbalanced cables available.

Just to make sure: if I run the -10dBV line outputs from the turntable into the XLR connections on the Neutrik jacks of my interface will it cause any problems? I think the manual suggests it will be fine but wanted to check

From the manual
"Neutrik XLR/TRS Jack combi-connectors provide microphone and line inputs. The line inputs are padded through the microphone preamplfiiers and have access to the pad, polarity reverse & HPF functions, therefore accommodating a huge range of input levels with freedom from overload"

The line input is via the TRS part of the combi-socket, while the XLR socket expects mic levels.

If you're going in via the XLR socket you'll need to select the pad and start with minimum gain. Ensure phantom is turned off before you plug the turntable preamp in. The mic impedance is a bit low for a Line input, but it will probably be okay.

If you find you're getting distortion you'll need to connect via the TRS sockets instead.

Thanks for the quick reply.

I was a bit confused by the statement that the line inputs are padded and run through the mic preamps - I hadn't considered the impedance, but did have a feeling I might cause myself problems or break something!

I've found something else to do today instead so I don't have to risk it. I'll just wait until tomorrow and use the proper inputs.

This is quite a common arrangement amongst interfaces and budget mixers etc. I avoids the need for a dedicated line buffer amp, and the noise penalty is negligible with modern mic amps. The line pad also provides the correct impedance while simultaneously reducing the line signal to a more appropriate level for the mic preamp.
