The white Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and Hardwired Servo-Bias 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 little 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 servo-bias Lectrosonics transmitters. Accessories are available separately and are not included with this configuration of the microphone.

Related Questions and Answers

Q: 1. In the first version, it was easy to clip audio at the transmitter level. Is this the case here, or has this been adjusted?

A: On the bottom of the receiver it has a 3 stage gain control, adjust it as need it. If you would like more control over the gain please use Rode's app that allows you to adjust the level in 3 dB increments from 0 to -30 dB.

Q: 2. is it possible to use these to amplify a speaker like in a lecture hall? our hosts get hoarse if they have to speak loudly enough for the entire class to hear

A: If you have a mixer in the lecture hall that is connected to an amplifier that is powering the speakers, then you can use an 1/8'' mini to XLR adapter like B&H # KOAXMMF to connect the Rode Wireless Go II to that PA system. The Rode Wireless Go II will not amplify a passive speaker.

Q: 3. If wired 3.5mm will this unit work with 3rd party lav mics, specifically the: • DPA Slim 4160 • Sanken COS 11

A: This system will work with any 3.5mm microphone that does not have a locking pin. In order to use it with DPA slim 4160 you need a microdot that's both 3.5mm but also has no locking pin that is designated to a specific company.

Q: 4. Looking to use this both on a set and in the field. I would prefer a way to hide the mics when on set, what is the range of quality audio pickup (say if it was placed on the table out of sight) or would it still pick up that quality audio under a jacket or shirt?

A: Any microphone will give you it's best sound when placed closest to the subject you are trying to record avoid having it far from the subject you recording, the best recommendation I can give while using this system is to add a 3.5mm lavalier microphone, lavalier microphones are meant to be used on the subject you recording giving you the best sound and are small making it easy to hide so it's not being seen in the video. https://www.bhphotovideo.com/c/product/1558252-REG/rode_lavgow_lavalier_go_professional_grade_wearable.html

Q: 5. One of my transmitters won't pair anyone else had this problem

A: It is possible for one of the transmitters to unpair from the receiver. If this happens, follow these steps as provide by Rode to attempt a re-sync: "If you need to reconnect a transmitter to the receiver, press and hold the pair button (‘∞‘) on the receiver for three seconds to enable pairing mode, then single-click the power button on the transmitter and wait a few seconds." If the problem persists, please reach out to Rode at (562) 364-7400.
