Saramonic UwMic9 (TX9 +TX9 +RX9)

Saramonic UwMic9 (RX9 + TX9 + TX9) – Dual-Channel UHF Wireless Lav Kit with Camera-Mountable Receiver

The Saramonic UwMic9 RX9+TX9+TX9 is a portable, dual-channel UHF wireless system designed for filmmakers and content creators who need reliable, camera-mounted audio for two people. It pairs two TX9 belt-pack transmitters with a single RX9 dual-channel receiver that mounts on your camera. The kit supports clip-on lavalier microphones on two separate talent while keeping your camera setup compact and easy to manage.

What this system delivers

The system delivers broadcast-quality wireless audio in a compact package. Every component uses sturdy metal construction. The receiver mounts directly to cameras and offers a headphone output for real-time monitoring. The transmitters provide 12-step input level control, muting, and power-lock features to prevent accidental changes. Together, these elements make the UwMic9 suitable for interviews, film dialog, field recording, vlogging, news gathering, and similar professional applications.

New features and improvements

This generation of the UwMic9 adds several updates over earlier versions. The TX9 transmitters now include 12-step input level control so you can fine-tune gain on each transmitter. The system runs an updated operating system and features a refreshed black trim around the LED displays for a more professional appearance. Importantly for professional cameras, the package now includes a 3.5mm to dual XLR output cable so you can connect directly to cameras with XLR inputs.

Simple setup with professional tools

The UwMic9 is plug-and-play. Simply attach the lavalier microphones, power on the units and start recording. The system operates in the UHF band from 514–596 MHz, avoiding the 600 MHz spectrum affected by recent FCC changes. It offers two banks of 96 selectable channels (groups A and B), an auto-scan feature to locate the best available channel, and infrared synchronization to make pairing transmitter and receiver quick and reliable. Backlit LCD displays on the transmitters and receiver provide readable feedback in bright or low light.

Power, range and flexible operation

The UwMic9 gives you features often found in higher-priced systems. It supports an operating range of up to 100 m, allowing freedom of movement for most field and studio shoots. The TX9 transmitters include High/Medium/Low RF transmission power settings so you can conserve batteries in controlled environments. The TX9 input wiring follows the standard 3.5mm TRS pin-out, making the transmitters compatible with a wide range of lavalier, headset, instrument and gooseneck microphones.

Transmitters include a muting function for privacy, and a flashing red LED reminds the user to unmute afterward. Both the TX9 transmitters and RX9 receiver feature power-locking to avoid accidental power-offs during use.

Compatibility and expandability

The UwMic9 is versatile for many recording setups. Locking 3.5mm mini-plug and dual XLR output cables are included so you can connect to DSLRs, mirrorless cameras, cinema cameras, camcorders, professional video cameras, action cameras, audio recorders and mixers. With the right adapter cables, the system can also be adapted for use with smartphones, tablets and computers.

The system is expandable and backwards compatible with older UwMic9 components. You can add optional transmitters and output cables sold separately, such as a HU9 handheld transmitter or the TX-XLR9 plug-on XLR transmitter, to broaden your setup. This backwards compatibility allows you to add new UwMic9 components to existing UwMic9 systems without replacing earlier gear.
