More Info

The SR 300 IEM G3 from Sennheiser is a rugged rackmount wireless audio transmitter. Ideal for monitoring applications, the transmitter has 1680 tunable UHF frequencies for interference-free operation. It also has a pilot tone squelch feature for eliminating interference when the transmitter is turned off.

The transmitter can be wirelessly synced with a receiver for quick setup, and also offers simple menu operation with an illuminated graphic display for more control options. An Ethernet port allows you to connect to a network in order to control the transmitter with the Wireless Systems Manager software from a computer.

An auto-lock prevents accidental settings changes, while an HDX compander provides high-quality audio. An integrated 5-band graphic EQ lets you shape sound to favor audio frequencies that you prefer. A mute function silences the audio.

Note! Receiver sold separately.
