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 robust, metal EM 300-500 G4 receiver offers a high-contrast, black-&-white OLED display. The display uses a streamlined menu system with a jog wheel and dedicated Escape button for quick menu navigation. The display also shows battery status of the associated transmitter.

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.

The receiver features an Ethernet (RJ45) port for network-based remote monitoring and control using the Sennheiser Wireless System Manager (WSM) software (free download available separately). Using your Mac/Windows computer, the software allows you to quickly coordinate frequencies in multichannel setups, display audio levels at the transmitter, battery status, and more.

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.

The detachable antennas with BNC sockets allow you to create a larger system using up to four EM 300-500 receivers connected to a single pair of remote antennas. This setup requires the ASA 214 active antenna splitter (available separately).

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.

Sennheiser offers a bodypack transmitter with variety of lavalier and headset microphone options to adapt your EW system as your needs evolve.

• 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.
