Dave, I use a RASCAL with my ArgoV and it works great and have no "Level" issues. I'm wondering if the unit you got was specific for your rig. That is, there have been a few different models of RASCAL over the years and I thought there might be more than an cable change between rigs. Also, I believe there is a trimmer that is set. I think RASCALS started out as a Kit, so it was up to the builder to set that trimmer. Without knowing the history of yours - I can only suggest looking at that.
I'm using an el cheapo Creative Labs sound card I added to one of the computer slots because I figured the quality would be better than the built in one. Also, most software is designed around Creative Labs. I take the Line In/Out/PTT off the five pin DIN on the back of the Argo so I don't have to mess with or change front panel rig controls. I set the level with the sound card sliders. Just a thought, maybe you have a check box checked to MUTE and by pushing the audio up all the way to the top you are squeeking just enought through. I don't know if Mute acts as an on/off switch or a big attenuator. Also, you have two sliders to set - you have the line in slider and the Master Volume slider. I set mine so they are mostly mid point on their scales. I bet more on one of those two sliders needing adjustment rather that a Mute Check Box. Good luck and 73, Paul
