The Sennheiser EW 300 G4-865-S is an easy-to-use rackmount wireless handheld microphone system with professional-level features for enhanced reliability and control. It offers variable RF power, an exceptionally wide tuning range, Ethernet networking for multichannel setups, and an intuitive interface with an OLED display and jog wheel. The system delivers high-quality, reliable audio to presenters, meeting participants, educators, and lecturers working in conference centers, schools, and universities.
The EW 300 G4-865-S includes a true-diversity, half-rack receiver housed in a rugged, full-metal chassis. The receiver's auto-scan function searches an 88 MHz UHF tuning range with 3520 selectable frequencies available, seeking out a clean, interference-free channel for your audio transmission. The high-contrast OLED display with automatic dimming, along with a convenient jog wheel allow you make quick adjustments, even in low-light situations.
This system includes an SKM 300 G4-S handheld transmitter equipped with an interchangeable MME 865 condenser supercardioid mic capsule optimized for speech and vocals. The handheld transmitter provides up to 8 hours of operation on two AA batteries, with a selectable 10/30/50mW RF power output for overcoming interference in difficult RF environments. The transmission range is up to 330'.
The Ethernet connection on the receiver supports both Sennhsier's Control Cockpit and Wireless Systems Manager (WSM) software for advanced frequency coordination in multichannel setups. Up to 32 wireless mics can operate simultaneously in the same space.
The EW 300 G4-865-S 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 EW 500 systems.
Lightweight Handheld Transmitter with MME 865 Supercardioid Capsule
The rugged, all-metal handheld transmitter features a backlit LCD that displays essential information and provides fast menu access. The adjustable input sensitivity on the transmitter accommodates mic levels ranging from booming voices to quiet speech, while controls can be locked out to prevent accidental changes during a performance. The transmitter syncs to the receiver via infrared with a quick press on the Sync button.
The SK 300 G4-S is powered via two AA batteries or a rechargeable BA 2015 Accupack battery (available separately). An LA 2 charging adapter (available separately) allows for recharging the Accupack without removing it from the transmitter—requires the L 2015 quick-charging unit (available separately).
The transmitter's interchangeable capsule design allows you to use a variety of optional dynamic and condenser mic capsules, with pickup patterns ranging from wide omnidirectional to narrow supercardioid—capsules include the MMD 835, MMD 845, MME 865, MMD 935, MMD 945, and MMD 42.
Easy-to-Operate Receiver with True-Diversity Reception
The system features 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32 user-programmable frequencies.
To prevent interference, the EM 300-500 receiver's true-diversity reception compares incoming signals on two independent receiver circuits to ensure optimal RF quality. To ensure crystal clear audio, Sennheiser's proprietary HDX compander technology maximizes the microphone's signal-to-noise ratio, while avoiding RF noise.
The built-in equalizer enables you to change the frequency response of the output signal; you can reduce the bass range and boost the treble range. The receiver also offers an adjustable output level range of 48 dB to match the audio input of your mixing board or PA system.
A headphone output with volume control is conveniently located on the front panel, allowing you to monitor your audio signal.
The back panel houses a balanced XLR output as well as an unbalanced 1/4" output. A kit is included for rackmount installation. The unit comes with a universal power supply and EU, US, UK, Korea, Australia, and China adapters.
For public address applications, the EM 300-500 G4 receiver can be integrated directly into the LSP 500 PRO wireless speaker system.
Time-Saving Options via WSM and Sennheiser Control Cockpit Software
Alternately, you can use the Sennheiser Control Cockpit software (free download available separately), designed to make the daily routines and workflows associated with the use of large wireless microphone setups in corporate and campus settings far easier. Wireless systems can be centrally controlled and monitored in real time, easily via a web browser on a smartphone, tablet, or laptop.
Enhance the Performance of Your System
Adding a pair of A 1031-U omnidirectional antennas or a pair of A 2003 UHF directional antennas increases the range of your system and offers increased protection against interference.
Add Functionality to Your System
- The discrete ME 2-II and MKE 2 lavalier mics provide exceptional clarity in spoken-word applications.
- The lightweight ME 3-II is a comfortable, durable headset microphone for active presentations.
