Overview

The Point Source Audio CO-3-KIT-SH-BE is an earworn condenser microphone engineered for speech reinforcement in theater, broadcast, and live event production — contexts where visibility is a liability and reliability is non-negotiable. Its omnidirectional capsule captures voice with natural tonal balance, free from the bass buildup and sensitivity variation that cardioid polar patterns introduce at close working distances. For spoken dialogue and vocal performance, this translates to a clean, consistent signal that sits well in a mix without heavy corrective EQ.

The mic ships pre-terminated for Shure wireless bodypack transmitters, maintaining native impedance and signal level through the wireless chain without the signal degradation or connector fatigue that adapters can introduce over a run. The detachable dual earset clip is purpose-built for quick deployment across multiple performers — a real workflow advantage in touring theater and broadcast environments where turnaround between shows is tight. Six windscreens are included out of the box, addressing one of the most common field failure points for earworn microphones before it becomes a problem mid-show.

Frequently Asked Questions

The CO-3-KIT-SH-BE is specifically terminated and wired for Shure wireless bodypack transmitters. It uses the correct connector pinout and impedance matching for Shure's TA4F (TQG) input. It is not cross-compatible with Sennheiser, Sony, or other wireless systems without an adapter.
The CO-3 uses an omnidirectional polar pattern, which is standard for earworn microphones. Omni capsules have no proximity effect, so the frequency response stays consistent regardless of distance from the mouth — critical for performers who move their head or speak at varying angles. In live environments, omni capsules are also less susceptible to handling and wind noise than cardioids at this placement distance.
No. As a lavalier-style earworn mic operating through a wireless bodypack transmitter, the CO-3 is powered by the transmitter's internal bias voltage — typically 1–5V. Standard 48V phantom power is not applied through wireless systems and is not relevant to this mic's power requirements.
Placement at the ear rather than near the mouth increases the working distance from the sound source, which means your front-of-house engineer will need to apply more gain from the transmitter and console to achieve the same SPL as a chin or cheek placement. In feedback-sensitive environments, work with your RF coordinator to optimize transmitter gain structure before the show.
The kit includes the CO-3 mic element with detachable dual earset clip, a body clip, and six windscreens. The dual earset clip design allows it to be worn on either ear and adjusted for different head sizes, making it practical for repertory theater or multi-cast productions where mic sharing is common.
