It used to be that you would have to use a lot of outboard effects equipment, racks of processors, and audio patch panels to get the sound and flexible routing you wanted.
Today, even the most modest digital console can perform some pretty remarkable feats.
Simply having access to reverb or compression on every channel is great. And being able to use a full parametric EQ anytime you need it is a life saver.
The precision available to sound techs with today's mixing console technology is amazing. And surprisingly, the cost of a decent console isn't too bad, considering the utility provided.
That being said, digital may not be for everyone. And that's OK. I'm still a fan of using a good old analog console. If it sounds good and gets the job done, use it!
But if you're thinking about upgrading from analog to digital, it's important to consider a few variables before selecting your console.
