Earthworks SR3314 Wireless Vocal Microphone Capsule
The SR3314 replaces the stock dynamic capsule on a 3-ring wireless handheld with an Earthworks condenser element, so a Shure, Audio-Technica, Lectrosonics, or Line 6 wireless system gains a wide 20 Hz to 30 kHz response and minimal proximity effect without buying a new transmitter. Off-axis rejection stays tight, which keeps monitor and stage wash out of the vocal.
It threads onto the wireless handheld body in place of the stock capsule and draws its power from the transmitter itself, so setup is a capsule swap, not a system replacement. Offered in natural stainless steel, black with a stainless mesh, or black with a black mesh - select the finish above.
