Recording/Monitoring Problems

Question

Hi Fellow Mac'rs!:
I am trying to use Logic Studio to do 2 things
1. Record an electric guitar through an interface into Logic, adjust levels and monitor that performance as I record it via headphones;
2. Record a vocal through the same interface, adjust levels and monitor that performance via headphones.
When I monitor/try to set levels/record guitar or vocals I am using headphones (plugged into MacPro headphone jack) to monitor, but hear nothing
When I playback, I hear recorded performance in headphones fine
Problems I am having
1. I do not hear my guitar or vocal imput and cannot monitor levels, nor adjust levels (vocal levels hardly register and on playback they are a whisper)
2. Guitar: there is response levels showing before recording, but no ability to raise/lower volume/set levels = no response
3. Vocals: there is response (barely) and levels showing before recording, but no ability to raise/lower volume/set levels = no response
Running Logic 9.1.4
Headphones: Sennheiser
Mic: AKG C1000S
Audio Interface: ESI UGM96
This set-up has worked before, now I am having issues described.
Could this be a hardware issue??
I hope I'm explaining myself properly.
Thanks!

Answer 1

Firstly
Software monitoring must be enabled in preferences / audio
You then need to record arm and press the little i button to input monitor
and while you are in there, just make sure that the ESI is still set to be the input inferface, logic can forget, or it can change.
secondly, make sure all of you analouge gain staging is correct
IE things are averaging around 0dbvu on the way in, if you have the metering of course.
the fader makes no diffrence to the file being recorded, all it does is affect the level sent to the output.
and finally also in audio preferences make sure that independent monitor level isn't checked.
i hope that helps,
