Title: USBpre or laptop mic input?
Post by: scervin on December 27, 2006, 02:18:29 PM: Was in the game for a long time, but DAT only. I'm not looking to record shows, I just want to have a way to get the signal into TrueRTA.

Looking into getting freq. response in rooms to help with calibration and room treatment. Do you think going USB in with the M-Audio USBpre give a significant difference over say a 48V phantom power supply using the mic input on the front of the laptop?

thanks

so a usbpre will sound better than the laptop.

USBPre for sure.

No question, whatsoever.

The USBPre is ideal for your use...I'd say most folks that use one, use it for the purpose of RTA. They are tanks...oh, and are built by Sound Devices, not M-Audio.

If M-Audio built them, they would be made from plastic.
:P

And they'd cost half as much and be half as good.

Unmodded ua5s should be available for a lot less than a usbpre

very true...probably could be found for about half the price.
I'm not a huge UA-5 fan, but it would work just fine for this...

Post by: dnsacks on January 09, 2007, 02:58:01 PM: the ua5 does resample its digital inputs, but I don't think that's pertinent for the initial requestor's intended use (getting an analog mic input into a laptop to monitor room acoustics.
