Whether you're equipping a university auditorium, conference center, or corporate training room, this system offers the reliability, sound quality, and flexibility that professionals demand.

Built for Clear, Consistent Audio in Any Environment

At the heart of the system is a rugged true-diversity receiver housed in a durable metal chassis. With 88 MHz of tuning bandwidth and 3520 selectable UHF frequencies, it automatically scans for the cleanest channel to avoid interference. The high-contrast OLED display and intuitive jog wheel make it easy to set up and operate, even in low-light environments.

Reliable Wireless Bodypack for Hands-Free Performance

The SK 300 G4-RC bodypack transmitter is remote-ready and perfect for presenters, instructors, and public speakers who need to move freely. It supports a wide range of Sennheiser-compatible lavalier and headset microphones, connecting via a secure 3.5mm locking jack.

With up to 8 hours of battery life on two AA batteries and selectable RF power settings of 10, 30, or 50 mW, the transmitter performs reliably even in RF-heavy environments. Its 330-foot transmission range offers ample freedom for large venues.

Network Control for Multi-Channel Systems

For large-scale or multi-room installations, the system supports network-based audio control via Ethernet. It works seamlessly with Sennheiser Wireless Systems Manager (WSM) and Control Cockpit software, allowing AV teams to monitor, coordinate frequencies, and manage multiple wireless microphones from a laptop, smartphone, or tablet.

You can run up to 32 wireless microphones simultaneously in the same space, making this system ideal for campus-wide or multi-room professional audio installations.

Backward Compatibility with Evolution Series

The EW 300 G4 system is fully compatible with previous generations of Sennheiser evolution wireless systems, including G1, G2, G3, and G4 components. You can mix and match receivers, bodypacks, handhelds, or plug-on transmitters with ease. It's also compatible with EW 100 and EW 500 series systems.

High-Performance Receiver with Easy Setup

The included EM 300-500 G4 receiver features true-diversity reception, ensuring stable signal quality by comparing two independent RF signals. Its built-in equalizer lets you tailor audio output by boosting treble or reducing bass to suit your voice or venue acoustics.

You’ll find both XLR and 1/4-inch outputs, a headphone jack with volume control, and all the tools you need for rackmount installation. A universal power supply with international plug adapters is included.

Optional Accessories to Expand Your System

Looking to scale up? You can connect up to four receivers using the ASA 214 active antenna splitter and add remote antennas like the A 1031-U omnidirectional or A 2003 directional antenna for extended range and reduced interference.

You can also add a handheld transmitter like the SKM 300 G4, with various mic capsule options, or use Sennheiser’s ME 2-II lavalier mic or SL Headmic 1 headset mic for crystal-clear speech in demanding applications.
