Signal level vs. recorded levels in ProTools way off
I've got what (to me at least) is a real stumper.
I've been working on a new record, and just overdubbed one last guitar part, but for some reason the recorded level is much lower than the level going into PT. In other words, I got a decent level going in, and then once I've recorded the sound, it's displayed as a tiny waveform with a tiny sound. Weird.
I'm running a Digi002 with PT LE 8.0.3 on an Imac 2.16 Intel with 2 gigs of RAM. I have a 7th Circle Audio Preamp box with two N72 pres that I use as a front end. So my signal is guitar, Countryman DI split into two signals, miced amp and a DI signal into PT. Looking at the meters and hearing over cans the signal seems fine, but once it's recorded the waveforms are tiny and the recorded sound is tiny as the waveforms.
After noticing this and trying to fix it, I completely tore down my rig, checked all the IO between the Digi and the 7th Circle and repatched everything, cause I figured maybe I had some weirdness going on in the signal flow. No dice. Then, I tried recording the same setup on another track with perfect results: the waveforms were normal for the input signal coming in and the recorded sound's level was in tune with the display.
I also copied the offending session and all audio and opened the copy and tried recording a guitar part with the same low signal results I described in my first paragraph. I used to work in computer graphics and sometimes the files would get corrupted. Could that be what's going on here?
I'm really stumped here. If anyone has any advice or has experienced something similar, I'd be glad to hear it. Thanks in advance, and I hope everyone is enjoying their summer.

Can't say about the sound, but the waveforms in ProTools can be made larger or smaller by clicking a button on the edit window. The height of the waveform has little to do with its signal level. For signal level you should look at the meters.

thanks
I know about the waveform tool, but what I'm saying is, the sound is hot on the meters and very low once it's in recorded form. I wish it was just a case of making the waveforms larger with the tool. It's a weird problem I know.

Hi,
You can use the PT meters when in Record input enabled, they will reflect the approximate levels going in.
You might be monitoring a little too loud, if it sounds good to you but the recording is too low. Try turning down your monitoring, and raising the input recording levels...
Cheers

Thanks. I am looking at the meters for both, and even when they're close to pegged in record, once the signal is recorded it's incredibly low compared to going in. It sounds loud going in and looks like a good healthy level going in, but once recorded the waveform is tiny and the recorded sound is an extremely soft representative of the healthy level that was being monitored and recorded into Pro Tools.Are you looking at the protools meters for both the recording level and the playback level?
Is there a trim control on the tracks?
These are just the first things that popped into my head. It's easy to overlook simple things when you are troubleshooting.
I am only monitoring loud enough to hear both the amp in my room and the signal on my cans. The amp is an AC30 clone going in through a THD Hotplate so I can run it at an extremely low volume while getting some bite, so I know it's not that.You can use the PT meters when in Record input enabled, they will reflect the approximate levels going in.

Thanks for the tips everyone! I think maybe it's a problem with this specific session in PT. It's a headscratcher for sure. I've moved on to another session file where the exact same set up was giving me no problems. Maybe I'll try the problem session again at a later time and just see if maybe I did something stupid. Either case, will report back, and if anyone has experience anything like this, please let me know. Thanks again to all!

A few things that came to mind:
-Are there any plug-ins on the track that might be messing with the playback level?
-What metering/monitoring selections do you have checked? Pre-fader metering? Input-only Monitoring?
-What version of PT are you using? If HD, have you checked the I/O or Hardware settings to see if there is anything weird going on with the trims there?
Hope that helps.

think i figured it out
So, I copied all the sound files into a new folder and built a completely new session with them. Then I re-recorded the same part on two new tracks just to make sure everything was working. I got perfect levels going in and the recorded signal was exactly what went it. I saved and closed the sesssion.
Then, I opened the problem session file and imported the new tracks into it. Guess what? Same low level as before, at least on the display. So, I clicked the waveform tool directly in the middle and suddenly all the waveforms were displaying similarly as tiny as the problem tracks. When I made them bigger, they all changed in size uniformly.
So, I guess my ears were playing tricks on me when I thought the tracks were sounding small. Everything seems fine now. Must have been some pref I accidentally changed just for new tracks if that's possible. A key combination I don't know about perhaps? Thanks to everyone for your assistance.
