Over the years, I have used a number of brands of DI boxes for all kinds of audio hookups. One of my favourite brands is Radial Engineering. They are made in Canada out west and used my hundreds of audio professionals across the country.
Direct boxes come in two types: passive and active. Each type has its advantages and uses. (Note: the article has comments from seasoned audio professionals on the types of DI boxes they use.)
Here are some of the Direct Boxes that I have used over the years on stages:
BSS AR-133 Active Direct Box
Countryman Type 85 Active Direct Box
Radial JDI Passive Direct Box
Whirlwind IMP 2 Passive Direct Box
Yorkville Sound YDI-1P Passive Direct Box
This is just handful of all direct boxes available on the market. Many of them are built tough to withstand the use and abuse on the concert stages of the world. Check out the manufacturer web sites for the complete lines of direct boxes available.
