The Electro-Voice BK-1632 was designed to deliver exceptional performance at an affordable price. The BK-1632 provides the flexibility and sonic quality required by today's working musician. The five mixing busses and channel patch points enable the use of multiple effects and processors. The prefade listen or solo system is invaluable for fine-tuning the mix. Vocalist will find the reverb to monitor send useful in providing a "wet mix” for stage monitors. With the addition of on-board phantom power, any dynamic or condenser microphone can be used without separate power supplies. The BK-1632 is a welcome addition to the growing family of Electro-Voice electronic products. The engineers at Electro-Voice have put 30 years of audio know-how and pride into the BK-1632.
