PostSubject: Why does a passive EQ need power?   Fri Feb 27, 2009 1:53 pm

The term 'passive' has to do with the circuit design, in that there are no active (amplifier, resistive) elements in the filter circuit. Whenever one of the filters is engaged, there is insertion loss, which is the gain loss from going through this part of the circuit. You need power to make up for this loss, in the form of op amps or vacuum tubes.
