I used a usb hub with a usb plugin for the mic, I saw this on Youtube, the reason for the hub was the ipad didn't have enough power to power the mic http://youtu.be/bf1d5lnx2qA

What were you using for interface and RTA mic for that? I have the studio six stuff on my ipad too and was considering the Smaart upgrade for when I'm not on the SL.

As of now you'll have to buy your own mic pretty sure the Behringer measure would be sufficent or the DBX RTA mic woould work to.

Re: the RTA420 microphone. Any idea why they would make this microphone with pin 3 hot? Is there something about measurement microphones that makes them want to go the opposite of generally accepted pin 2 hot? Does this have any effect on measurements? Given that there is no polarity reversal switch for the talkback mic input, should I consider using a pin2/3 swap adaptor?

All input is appreciated.

Milton,

Back in the days of old, when the first batch of RTA-420s was ordered, the mic was ordered as Pin 2 hot and arrived Pin 3 hot. When we finally ran out and reordered, we decided to keep them Pin 3 hot since the new ones are identical to the originals. This will have no effect on your measurements in the StudioLive Smaart integration.

just curious, are we going to burn up mic's on the talk back? in the past i had two burn up due to the voltage. that unit got returned but i have not plugged anything in the talk back as i don't feel comfortable knowing insanity is repeating the same mistakes, expecting different results.
1.7 sounds very nice and i feel fortunate to have PreSonus product with great free updates.

I think yours was a fluke Mike. I can't seem to recall anyone else who has experienced this problem. And I've not experienced it on several different studiolives.

Phantom power can range anywhere from 9V to 52volts. Maybe Johnny A could clarify how that much of a voltage difference would affect the performance (if at all) of the mic in measurement mode.

A while back, the Prosound web addressed a number of measurement mic questions and it was said that most measurement mics (at least the "more affordable ones) are built in a few facilities, and branded/packaged per customer spec. The jist of the discussion was that the big difference between a top end mic was the LF and HF performance, and that the critical "midrange" where the most benefit can be derived in flattening the response are largely pretty good across most of the mics available.

One benefit of the better mics is a calibration certificate that shows the response of the mic across the full spectrum. That would be nice, but not necessary. for our typical applications.

1+ for the RTA420, it's what I usually recommend...

I think your right Mono, in my findings all phantom products state 48 volts so when i measure 52 on the outputs of the talk back, i get a little worried plugging in a $200 audix. I did make an inline voltage drop and plan to use a much less expensive mic on the SL. I am excited about more functions of Smaart in the 1.7 update.
I've taken courses from smaart and found the software to be my best tool. (ears are the best) So using the full blown product is nice, however setting it all up takes time. Presonus having this update will make things quicker and easier,
So here we sit, waiting on Christmas to come early... Is it Monday Yet ?
Thanks again Presonus for all the fun and greatness.

Sorry for the delay, didn't see the replies here.

Many condenser microphones (including most of the common measurement mics that we use) can operate using various phantom power voltages. The Audix TM-1, for example, can operate when powered with between 18 and 52 volts. Powering your microphone at something other than 48v should have no effect on the measurement if the microphone is designed to operate at that voltage. Here's an interesting write-up from Sound Devices about phantom power:

Yes! you can re-create the trace in Smaart by setting transfer function measurement settings to 1/3 octave smoothing, 3 second averaging, and 50% Coherence blanking.

Given that the talkback input already is phase reversed (I've filed a bug report about this since uc1.2 a long time ago, but haven't tested it with uc1.7) you are good to go
