Question regarding Shark & Audio Buddy

I have been slowly buying equipment to record radio broadcasts with and I would like to know something.

I had purchased an audio buddy which helped to boost my voice recordings.  I had that hooked up with a TCM 1050 Vacuum Tube Condenser Mic Power Supply.  I recently purchased a SHARK DSP110 to help compression with voice range etc.... I want to know if I need to use both the audio buddy and the SHARK DPS 110 or can I just use the SHARK?  It seems that I'm overmodulating more when both are hooked up?  Do these both have pre-amps in them?  I'm thinking I can send the audio buddy back and keep the SHARK.  Please advise.

Regarding the SHARK DPS 110 - I'm trying to figure out what compression amount to put on it from 0 to 100.  Any suggestions?

I'm just learning how to get stuff hooked up - so

I think you only need one, and yes, they both have pre-amps. The Shark appears to have more "bells and whistles," but I've used neither, so I'm not much help as far as compression settings, etc. Hopefully someone with experience with these will chime in. Good luck-

Thanks Tim....I'll see if anyone else responds.
