The beige Sanken COS-11D Lavalier Mic for Lectrosonics Transmittersis a subminiature lav microphone designed to deliver clear, full-bodied sound and reliable performance, making it a popular choice among industry professionals in broadcast, TV, theater, film, videography, and more. 

Engineered to meet the standards of modern digital wireless microphone systems, the COS-11D is RF shielded to eliminate interference issues and ensure a pristine audio signal. The microphone capsule features a rectangular design that sits vertically, increasing the surface area and allowing this tiny mic to offer a rich, full sound that outperforms many larger models.

The mic's 50 Hz to 20 kHz frequency response rolls-off extreme low end and provides accurate, transparent audio reproduction with a small presence boost in the 6 kHz area for crisp, intelligible speech. With a forgiving omnidirectional polar pattern that picks up sound in a 360° pattern, levels stay consistent, even when the subject turns away from the mic.

A water-resistant mesh screen protects against humidity, perspiration, makeup, bad weather, and other potential on-location issues, while the durable cable is also moisture-resistant and built to stay soft and pliable, even after extended use. This version of the COS-11D terminates in a TA5F connector and is wired for use with non-servo-bias Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Related Questions and Answers

Q: 1. Do I need to purchase anything else beside the antena?

A: This should work with any receiver but this antenna needs DC power. Many receivers can supply DC at the antenna port, but if yours does not you'd need to consider how you are going to supply power to it. You can use a DC power supply if you are close enough to an AC outlet. If not, you'd need to supply power via a DC inserter between the receiver antenna jack and the cable to the antenna. Lectrosonics makes this. Part number is BIAST and also needs a CH12 power supply.

Q: 2. Does this antenna work with SRa receivers?

A: Yes it will: The Lectrosonics AMJ Color Coded Whip Antenna is a replacement antenna for the SM, UM200, UM400, UM190, UM195, UM400a and SRa beltpack transmitters. The antenna features a standard stainless steel connector SMA connector and nearly indestructible steel wire.

Q: 3. Can I simply attach this to a shoe mount on the FX3 and use it?

A: Yes. The CS-M1 will work with the FX3

Q: 4. is this price for a pair or single

A: This antenna is a single unit.

Q: 5. Can the Lectrosonics PCA900 Printed Circuit LPDA Antenna be used on a wireless microphone system?

A: as long as the frequencies match and you have an antenna input that will accpet a 50ohm BNC.

Q: 6. this unit come with one 3.7V battery or two?thanks.

A: One.

Q: 7. Is there an adapter for lectrosonics compatible (TA5F) lavs, or would I need to get new lavs for this?

A: Although we have seen custom adapters to convert TA5F to 3-Pin Lemo, we recommend using lavaliers with dedicated wiring for the Lectrosonics SSM Digital Hybrid Wireless Miniature Transmitter. B&H does not offer adapters of this nature at this time.

Q: 8. Is it okay to keep it in the rain or should the antenna be covered with a plastic bag?

A: The Lectrosonics ALP620 Perforated LPDA Shark Fin Style Antenna is not IP-rated; therefore, it cannot be left out in the rain. Using a plastic bag or rain cover to protect it will actually affect the wireless range of the antenna, making it prone to RF interference.

Q: 9. is this protective case black as in the photo or blue Porta Brace?

A: It is black.

Q: 10. Does this transmitter work with the Lectrosonics IFBR1B Bodypack IFB Receiver (VHF: 174 to 216 MHz) ? I noticed the frequency range was slightly different so i want to be sure.

A: Yes, The Lectrosonics IFBR1B is compatible with IFBT4 transmitters, as long as there is frequency band overlap between the components
