beginner problems

i am having trouble when recording and listening on the
same mixer (a little Behringer MX802A). I am sending to my
Gina sound card from the aux sends 1&2 and receiving on
stereo line ins 5&6. I am hearing both what is going in
directly and hearing what is going through my computer and
back--and the result is this fairly nasty flangy sound. I
think the problem would be solved if there was a way to
disable the input monitoring somehow so i was only to hear
what is going through the computer. is there a way to do
this on the mixer or from within Vegas........???
thanks.....

another stupid problem...how can you record in mono and split the
signal left and right. i know how to use soundforge to do it with
something that is already recorded but how do i do it from within
vegas as i am actually recording.

After you arm a track, click on the inport button on the track and
then select left or right.

thanks for the response Peter.
i've done that...is there a way to split the signal so you get it in
both ears?
Also, any advice about the monitoring situation I am encountering.
What is the best way to set up using one small mixer? Thanks.

I don't follow you I guess. What do you mean split the signal?

As far as montoring....

Use either the Gina or mixer for monitoring, not both. This is what
is causing the flanging. Even though the Gina can monitor inputs to
its outputs, there is a delay (1- 3ms) associated with the A/D
converts that will cause this flanging.

If your source is going to the mixer, then monitor the input through
the mixer. If you want to monitor through the Gina, then you have to
kill the monitor mix through the Behringer.

I just looked at the block diagram of the MX802A. One aux is pre
fader the other is post. This makes it tough to route a stereo pair
to the Gina with out having some of the signal also go through the
MX's main bus. There is a mod discussed in the MX's manual on how to
convert the Aux 2 to pre fader on a per channel basis. Doing this mod
on one channel would allow you to have to input sources going into
the MX and then routed directly to the aux buses with out going
through the main buses. The nice part is that you will still get EQ
on the input channels.

It would be nice if there was a way to mute input channels, that way
you could A/B the input to the board and the Gina's input monitoring.
If you do the Aux mod, you can still do this, but you will have to
fade the channels to -inf inorder to A/B.

So, assuming you do the Aux Mod on Channel 2:

Aux Send 1 : Gina in l
Aux Send 2 : Gina in 2

Gina 5/6 : MX 5/6 (or what ever)

With Channel 1 and 2 main fader set to -inf, you can control the
input to the Gina using the Aux 1 and Aux 2 sends on these channels.
You would then set the Gina to Monitor inputs through 5/6 and adjust
the MX ch 5/6 for the monitor mix.

Alternatively, you could set Chan 5/6 of the MX to -inf. and set the
Chan 1 and 2 level on the MX for monitoring your source.

Do you have a patch bay? If not get one, it will make life easier for
you to deal with routing. This way you can easily re-route the MX
chan 1 and 2 inputs to what ever it is you want to record.
(Alternatively you could just make all channels treat Aux 2 as pre
fader.)

I truly appreciate your time...

i seem to be getting more confused. I thought I had atleast part of
my problem solved. Why should I not simply mute the monitors from
within the "echo console?" This gets rid of the flang/latency issue.
Are there drawbacks that I am just not thinking of?

I had gotten to a new and seemingly related problem. I have two
tracks and want to record a third while listening to the first two. I
cant seem to avoid recording the first two onto the third. Is there a
simple fix. The SF support made me overly optimistic by saying that
my sound card probably had a "record all you can hear" option that
needed to be turned off. What do you think?

thanks so much.

This is what I thought I said? Use one or the other, not both.

This sounds like a mixer routing problem - at least as to how you
described how you have your mixer set up using the Aux sends as
inputs to your Gina.

I _highly_ suggest you get a copy of Mackie Compact Mixers by Randy
Trubit. While it is not specific to your hardware, it is a good
general coverage of how to use mixers. There are aslo a number of
other general recording references out there.

THe other thing to do is to read and study the block diagram in your
manual for your mixer. Draw some pictures of how things are connected
and routed in your system. Understanding the signal flow and how the
mixer/software/Gina interact is crucial to getting all of this to
work as expected. It is worth the time and effort to under stand the
signal flow in your setup. There is a good signal flow diagram in the
Vegas help file as well.
