The AT8464 dual-ear microphone mount is included with the BP892 headset and allows you to convert your single ear-worn BP892 MicroSet® to a dual-ear-worn unit for maximum stability and comfort. The BP892 fits on either side of the dual-ear microphone mount, allowing the microphone to be worn to either the left or right of your mouth. The headband easily adjusts to fit both children and adults. The AT8464 is available in black (AT8464) and theatre beige (AT8464-TH) and is compatible with all BP892 and AT892 MicroSet models. |
Ultra-lightweight headset mic handles high SPL with excellent
fidelity. Low profile design is ideal for high quality
presentations, live or on air. Black. Includes APS911 phantom
power adapter. Requires 9-52 V phantom power.

The C 544 L is a head-worn miniature condenser microphone with a convenient behind-the-neck headband. The microphone has a cardioid polar pattern and therefore "prefers” sounds arriving from the front (from the userʼs mouth).
The microphone body containing the condenser transducer is shock mounted on the microphone arm in order to suppress cable and mechanical noise. The microphone arm will place the microphone in front of the corner of your mouth to minimize pop noise and protect the microphone from contamination. The supplied windscreen makes the microphone even less susceptible to wind and pop noise.
A special moisture shield on the microphone capsule makes it difficult for moisture and makeup to penetrate into the microphone. This barrier prevents the microphone sound entries from being clogged by sweat or makeup which would make the sound dull and reduce the sensitivity of the microphone. Therefore, never remove the moisture shield from the microphone.
The C 544 L is a condenser microphone and therefore needs a power supply.
