Frequently Asked Questions
What gain staging approach works best with the CO-3 on a Shure wireless transmitter?
The practical starting point is to set your transmitter gain so that peaks from normal speech land around -12 to -6 dBFS at the transmitter input — the CO-3's omnidirectional capsule is voiced for speech and doesn't need heavy padding. Because it's omni, you don't get the proximity bass boost you'd expect from a cardioid, so you can trim slightly more gain from the transmitter without losing warmth in the low-mids. Trust your ears: clear consonants with no sibilance distortion is the target.
Does the omnidirectional polar pattern cause problems in live environments with stage monitors or room noise?
Omnidirectional patterns pick up sound from all directions, so stage monitor bleed and room ambience will be present in the signal. That's the trade-off you accept for the mounting freedom and consistent off-axis response an omni provides. In controlled environments — houses of worship, lectern presentations, broadcast studios — this is rarely an issue. For high-SPL live stages with close monitors, a cardioid earworn would be a better fit.
How does the CO-3 attach and stay in position during active movement?
The CO-3 uses an earworn design that hooks over the ear to hold the capsule in a consistent position near the mouth. The lightweight construction — typical of discreet presentation microphones in this class — means it stays comfortable across extended wear without fatiguing the talent. Position it with the capsule approximately at the cheekbone for the most natural pickup of forward speech.
What wireless transmitters is it compatible with beyond Shure?
The CO-3-SH-BL is specifically wired with a Shure-compatible connector. It is designed for Shure wireless transmitter bodies and is not interchangeable with TA4F (mini-XLR) connectors used by other brands without an adapter. Confirm your transmitter model is a Shure-compatible body before purchasing.
Is phantom power or any external power required for this microphone?
No separate phantom power is required — the CO-3 draws its operating power from the Shure wireless transmitter body it's connected to, as is standard for this class of earworn microphone. Battery management is handled entirely at the transmitter level.
