ZAPCO OEM 2CH Speaker to RCA 9.5V output


ZAPCO ASP-OEB is a basic 2-channel line converter with a difference. A true active preamp with exactly the same circuitry that is in our other active adapters. it has the same 9.5-volt preamp that all our signal processors have. ASP-OEB also has adjustable preamp gain and automatic turn-On that can be defeated with the flip of a switch if desired. With the ASP-OEB you will get the same crystal clear mids and highs and rock-solid bass you expect from any Zapco signal processor.
