The Sennheiser SK 300 G4-RC is a bodypack wireless transmitter compatible with the EM 300-500 G4 receiver. The rugged, all-metal design is comfortable for performers and presenters to wear for daily use on stage. The transmitter operates on an exceptionally wide 88 MHz UHF tuning range with 3520 selectable frequencies available. It provides up to 8 hours of operation on two AA batteries, with a transmission range up to 330 feet and a selectable 10/30/50mW RF power output for overcoming interference in difficult RF environments.

The SK 300 G4-RC features a locking 3.5mm connector with an adjustable mic/line input level to accommodate the compatible lavalier or headset microphone of your choice. It is also equipped with a 2.5mm jack to connect the RMS 1 remote mute switch (available separately). The switch adds easy-access push-to-talk and push-to-mute functions to your transmitter.

When the Sync function on the SK 300 G4-RC is engaged, the transmitter and receiver quickly link to the same frequency via infrared. The transmitter's backlit LCD displays essential information, while the convenient programmable mute function can be locked out to prevent accidental changes during a performance.

The unit can also be powered by a single rechargeable BA 2015 Accupack battery (available separately). Side contacts allow for recharging the Accupack without removing it from the transmitter—requires the L 2015 quick-charging unit (available separately).

The SK 300 G4-RC is backward-compatible with all previous evolution systems. You can mix and match G4/G3/G2/G1 receivers or bodypack, handheld, and plug-on transmitters. It is also compatible with EW 100 and EW500 systems.
