The gray Sanken COS-11D Omni Lavalier Microphone with Reduced Sensitivity and Non-Servo TA5F Connector for Lectrosonics Transmitters is 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. Accessories are available separately and are not included with this configuration of the microphone.

Q: 2. Can i use this as well as my rode mic on the hot shoe?

A: That would depend on which Rode microphone you have, and what you are truly asking in the question. If you were asking if you can plug a Rode microphone into the transmitter: Yes, If you have a Rode lavalier, or even a shotgun microphone that terminates 3.5mm it work with the transmitter. You're asking if you can use your Rode microphone and the Blink 500 system into your camera simultaneously: You will need some kind of mixer, such as the Saramonic SR-PAX1, or the SR-AX100. But keep in mind the SR-AX100 is only for battery powered microphones, it has no pre-amplification. If you want pre-amplification, the Saramonic SR-PAX1 is a much better bet. I hope that helps.
