The Saramonic UwMic9 RX9+TX9 is a portable, dual-channel, camera-mountable UHF wireless system that provides broadcast-quality sound. While the RX9+TX9 is a single subject system, the dual channel receiver allows a second transmitter (sold separately) to be added for use on multiple subjects simultaneously. This system is perfect for DSLRs, video cameras or portable audio recorders for capturing interviews, film dialog, field recording, broadcast TV, news gathering, vlogging, YouTube videos and more. Every component features sturdy metal construction and delivers excellent sound quality in a low-cost package. The entire kit is ultra-compact, lightweight, and easy to bring with you on every shoot.The UwMic9 is remarkably easy to use. It works right out of the box. You just plug in the mic, turn on the power and go. It utilizes the UHF (Ultra High Frequency) spectrum, which helps you avoid interference, and its 514-596 MHz range is not impacted by the FCC’s ban of the 600 MHz frequencies. An automatic-scan feature locates the best available channel for you and the infrared synchronization makes the process a snap. There are 96 channels available, which enables you to run multiple sets of UwMic9 systems at the same time without issues. Easy-to-read backlit LCD displays on both of the transmitters and the receiver let you make quick adjustments to the intuitive menus in the brightest or darkest environments. The RX9 receiver also includes a headphone output, enabling real-time audio monitoring if your camera lacks a headphone output.FeaturesComplete one-person UHF wireless lavalier microphone kit with a single, dual-channel camera-mountable receiver that provides reliable broadcast-quality soundEasy-to-use and works right out of the box with plug-and-play operationBuilt-in headphone output so you can always hear your sound — even when your camera lacks a headphone jackDurable all-metal construction with easy-to-read backlit LCD displaysOffers up to 330-foot (100m) operating distance with auto-scan feature finds the best channels for you and infrared makes it easy to sync channelsSpecificationsRX9 ReceiverChannels: 96 selectable channels in 2 groups (A and B)Wireless Frequency Range: 514 MHz – 596 MHzOscillator Type: PLL synthesizerOutput: Locking 1/8” (3.5mm) TRS mini-jackAntenna: 1/4 ?wire antennaAudio Output Level: -60 dBVHeadphone Output Level: 30mW (16 ohm)Sensitivity: -95 dBmSignal to Noise Ratio: 70 dB or moreVoice Delay: 12 msReference Deviation: +/- 5 kHz (-60 dBV, 1 kHz input)Frequency Response: 40 Hz to 18 kHz (+/- 3dB)Distortion: 0.5% or lessSpur Suppression: -60 dBBatteries: 2 LR6/AA size batteriesDimensions: 6.73 x 2.5 x 1.18” (170.9 x 63.5 x 30.0mm)Weight: 7.72 oz (218.7g) (without batteries)TX9 TransmitterChannels: 96 selectable channels in 2 groups (A and B)Wireless Frequency Range: 514 MHz – 596 MHzOscillator Type: PLL synthesizerInput: Locking 1/8” (3.5mm) TRS mini-jackReference audio input level: –60 dBV (MIC input, 0 dB attenuation)Antenna: 1/4 ?wire antennaSignal to Noise Ratio: 70 dB or moreVoice Delay: 12 msReference Deviation: +/- 5 kHz (-60 dBV, 1 kHz input)Frequency Response: 40 Hz to 18 kHz (+/- 3dB)Distortion: 0.5% or lessSpur Suppression: -60 dBBatteries: 2 LR6/AA size batteriesDimensions: 6.73 x 2.5 x 1.18” (170.9 x 63.5 x 30.0mm)Weight: 7.46 oz (211.4g) (without batteries) Saramonic UWMIC9TX9RX9 Wireless Lavalier Microphone System With 2-Channel Receiver.
