Volume control on record.

I want to know how to control the recording volume in Ardour.How can I to monitor the overall output channels?
Thanks in advance.GVS.
PS I work in Mandriva Linux,Pentium i7 64 bit,Jack works fine.

If by recording volume you mean gain of the input, you do that via your audio hardware, Ardour has nothing to do with that.

If you mean monitoring volume, that depends on if Ardour is doing the monitoring, or your hardware. If Ardour is, you would do so like any other mix in Ardour, if your hardware is doing so you need to go through your audio hardware.

What exactly is the problem you are trying to solve?
