The Sennheiser EM 300-500 G4 Wireless Receiver 470-558 MHzis a true-diversity, half-rack wireless receiver housed in a rugged, full-metal chassis and compatible with the SK 500 G4 bodypack transmitter and the SKM 500 G4 handheld transmitter. It offers professional-level features for enhanced reliability and control, including variable RF power, a wide 88 MHz bandwidth, Ethernet networking for multi-channel setups, and an intuitive interface with an OLED display and jog wheel. The receiver delivers high-quality, reliable audio to presenters, clergy, lecturers, and performers working in business and educational settings, houses-of-worship, theaters, or on musical stages.

The EM 300-500 G4 is backward-compatible with all previous evolution systems. You can mix and match G4/G3/G2/G1 bodypack or handheld, and plug-on transmitters. It is also compatible with EW 100 systems.

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

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 multi-channel setups, display audio levels at the transmitter, battery status, and more.

The detachable antennas with BNC sockets allow you to create a larger system using up to four EM 300-500 G4 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.

Related Questions and Answers

Q: 1. WHAT RECEIVER DO I NEED FOR THIS?

A: Ideally you will get the EK500 receiver (for portable/camera work) or the EM500 for rack mount). It is also compatible with the 100 and 300 EW Evolution receivers, but in that case, not all frequencies of the transmitter will be available on the receiver. If you want it for camera work, this transmitter is also sold as a kit with a receiver, or as a kit with a receiver, body pack transmitter, MKE2 lav. Item# SEEW500BG4G1 and Item# SEEW500FILM1

Q: 2. How many mics can this receiver connect to, does it work with AVX Bodypack Transmitter?

A: This single receiver pairs with one UHF transmitter from the Sennheiser ew 500 series only. An AVX transmitter would not work, because it operates in a digital frequency range. An example of a full system is the Sennheiser ew 500 Wireless G4 Handheld Microphone System with e945 Capsule AW+ (470 to 558 MHz), BH #SEEW500G494W or for a clip-on mic, the Sennheiser ew 500 G4-MKE 2 Wireless Lavalier Microphone System AW+ (470 to 558 MHz,) BH# SEEW500G4MKW.

Q: 3. Can I use this plug on for a Rode NTG3 mic and a Sennheiser EK 100 G3 Wireless Receiver (G: 566-608)? Thank you.

A: You sure can.

Q: 4. How much difference does 30mw vs 50 mw have on reliability, reception and range?

A: Every milliwat may count when tolerances are very close. It sometimes can be a game of inches.

Q: 5. I have the Sennheiser EW 112P G3-B Omni-directional EW system. Will this work with the G3 receiver?

A: Hi Brian - while Evolution Wireless G4 is backward compatible with EW G3, the products need to operate within the same frequency range. Your current product is the EW 112P G3 in the B-Range, which is 626-668MHz and the AW+ range of this SKP 500 is 470 - 558MHz, so they wouldn't be compatible. The larger issue is that the FCC has effectively banned wireless devices in the 600MHz range, effective July 13, 2020 - to help offset the costs of transitioning to new, legal devices, Sennheiser is offering a rebate on the trade-in of 600MHz products and the EW 112P G4 sets are also on sale through the end of April 2020 at B&H.

Q: 6. Will this microphone work with the Sennheiser L 2015 Charger?

A: Yes, the Sennheiser L2015G2 Charging Station, BH #SEL2015G2 is the appropriate charger for this transmitter, with the Sennheiser BA 2015G2 Rechargeable Battery Pack, BH #SEBA2015G2 installed.

Q: 7. Will this work with the EW 100 G3 receiver?

A: The G4 series is backwards compatible with the G3 series, so you can program this transmitter to work with your EW 100 G3 receiver. The 500 G4 series divides the available UHF range for wireless microphones into two large 88 MHz blocks. Just be sure to get the appropriate range that includes the frequencies for your G3 receiver.

Q: 8. Will this work with the Senheiser AVX Wireless system? I want to plug this into an MKH416 and record boom audio wirelessly into camera.

A: No, the Sennheiser SKP 500 G4 Pro Wireless Plug-On Transmitter is not compatible for use with the AVX system. The G4 series is a UHF system (this particular transmitter operates on the 470 to 558 MHz band) while the AVX series is a digital system that operates at 1.9 GHz. Sennheiser does not offer a plug-on transmitter for AVX. The G4 series system is a better option if you need to use a plug-on transmitter that can supply phantom power for your MKH416. The SKP 500 transmitter is available separately or as a complete system with the EK 500 transmitter -- Sennheiser EW 500 BOOM G4 Camera-Mount Wireless Plug-On Microphone System with No Mic - AW+: 470 to 558 MHz (B&H # SEEW500BG4AW).

Q: 9. Is the G4 (470-558MHz) compatible with an Ek100 G3 receiver (516-558MHz)?

A: Hi Brite - the two series are absolutely compatible as long as they are in the same range. As the AW+ range (470-448 MHz) transmitter extends beyond the lower frequencies of the A range EK 100 G3, you won't get the full benefit the transmitter is capable of for tuning, but you'll be able to scan with your EK 100 G3 and sync to the new SK 300 G4. Please note that the frequency presets will be different, though this isn't an issue when it comes to scan/sync capabilities.

Q: 10. Can I use with MKH 70?

A: Hello Mikhail - the SKP 500 is capable of providing the 48V Phantom Power required by the MKH 70; please note that the SKP 500 is a transmitter only and you'll need to pair it with a receiver (i.e. EK 500 G4) or purchase a system (i.e. EW 500 BOOM G4) to ensure you have all the appropriate products for a successful shoot.
