EWI ADB-404 Frequency Filter Active DI Box 19" Rack Mountable

EWI ADB-404 Rack-Mountable Four Channel Active Direct Box. This is ideal for the keyboard player or any other musician (or A.V. company) that needs four D.I.’s in one spot. This is an ACTIVE D.I., so you will see little if any degradation of the signal put-through. Also, this unit will need to be powered by a 48volt phantom power feed from the board or with an outboard 9V power supply (included).


This is a profession grade active D.I., suitable for studio use, or touring. The transformers used (which are the key to a nice, fat, clean D.I. signal) are very high quality and specifically made for widely varying dynamic musical program. The transformers are specifically manufactured for EWI to ensure high reliability and performance that is acceptable to all but the most discerning users.
