User Techniques and Applications

The Equitek 

E-350

 can be used in a broad number of applications, ranging from live reinforcement to the most critical studio situations.  The 

E-350

 is ideal for

vocals and voice overs, yet it also excels at some of the most demanding instrumental projects.  The 

E-350

 is great for virtually all acoustic, wind, and amplified

instruments.  It will even handle the explosive dynamics of drum kits with ease.  The 

E-350

 has been proven to be outstanding in all of these applications and more.  Its

uncolored sonic characteristics allow you to decide how a instrument or vocal will sound in the mix.
