I had been using GB with my G5 with Digital speakers for audio output and an old analog mixer to control my mic for vocals. So I have my microphone connected to my mixer line in, then the L/R main mix from the mixer goes to a mini jack in the line in in the back of the G5 and a pait of Creative digital speakers are connected to the digital out at the back of the G5. For my guitars I use the Monster mini jack cable to the the line in on the rear of the G5, and headphones to monitor the vocals as I record.

Here is my problem.
I have purchased Tannoy near field active speakers to use instead of the Creative speakers for better sound which I have connected to my mixer L/R out by 3.4" jack, so that the sound from GB goes from the G5's line out audio into the mixer then out thru to the Tannoy speakers, but I want to record my vocal and monitor them on my Tannoys, what am I doing wrong? I can seem to find a way to get my vocals directly into GB and I dont want ot use an iMic. Do I need another kind of mixer or preamp USB unit for my vocals? I have been giving by a friend an Edirol UA-700 audio capture USB unit for guitar and vocal would that be better?

Many thanks if you can help
