Royer R-122MKII-MP Matched Pair of R-122 MKII Ribbon MicrophonesThe R 122 MKll takes the R 122 to a whole new level, delivering unprecedented flexibility for ribbons via the addition of a switchable 15 dB pad and a switchable bass cut filter. The switches are completely out of the circuit when disengaged so when both are off, the microphone is for all purposes an original R 122. The switches are located on the back of the microphone and recessed to prevent accidental activation. Features: Phantom powered circuitry
