For the past couple of years I’ve been using the CEntrance R4 audio interface in the booth and on the road. I’d been using the original CEntrance MicPortPro for many years, then the R4 replaced it – Clean pres with plenty of dynamic range, very clean phantom power and absolutely well built. When recently the R4S (Studio model without battery) was on sale – I decided to purchase a second unit. (One for the booth, one for mobile.) I also decided to splash out on a new set of headphones for Vo work – CEntrance Cerene db. It’s nice to have such a good set of headphones in the booth – controlled natural, transparent sound.
