The make up of the Vintech Audio X73 isn't too hard to follow as everything is pretty clearly labeled and organized well. If you have ever used a Neve board, you'll probably be somewhat familiar with this configuration because it is modeled after a Neve pre. As far as parameters go, it has a line level (gain) knob, and then has four bands of EQ - one of which is a high pass filter. It also has a knob for overall output level and has switches for phantom power, EQ in/out, and phase. This isn't too hard of a channel strip to use as these are features that are pretty ubiquitous. I haven't seen a manual for the Vintech Audio X73, so I can't say if it would be helpful or not.
The sound quality of the Vintech Audio X73 is outstanding. It is a direct copy of the Neve 1273 pre, just put out by a different company. It would be very hard for someone to tell the difference between this and the real thing, as this is made really well. I would recommend using this pre with anything and everything as it is just an overall great sounding pre and will work in just about any situation. I love the way that it sounds on vocals and overall you are getting a thick sound with this pre...
I first used the Vintech Audio X73 about two years ago and have since always been impressed with this pre whenever I am able to use it. I believe that Neve makes the best microphone preamplifers that money can buy, and this does a great job of copying that formula. While definitely expensive for those on a budget or with smaller home studios, it is still a great deal because when compared to one of these manufactured by Neve, this will cost you a lot less. If you are looking for a top flght mic pre, regardless of if you are a professional or an amateur, the Vintech Audio X73 is a great place to start.
