Sennheiser ew 500 G4-945 radio handheld microphone system

General Description

Sennheiser ew 500 G4-945 wireless system with handheld supercardioid microphone transmitter and diversity receiver.

Evolution wireless has been the industry standard for flexibility, ease of use and reliability for wireless microphone systems for years and the new and improved G4 system looks to continue this trend.

Great vocals begin with great capsules: All 500 series vocal sets are equipped with capsules from Sennheiser’s successful evolution 900 stage line. The evolution 900 series is stage proven and used by many acts on tour. Enjoy one-touch setup with the sync function. This system uses a dynamic supercardioid microphone capsule based on the evolution e 945 which allows the vocals to cut-through the mix while remaining warm and full sounding.

With a wide tuning range and easy to use interface, the half-unit size receiver has true diversity for stable RF and is supplied complete rack mounting brackets.

The wireless Sennheiser G4 ew 500 range is available in the following frequency ranges:

Range Aw+ = 470 - 558 MHz
Range Gw = 558 - 626 MHz 
Range GBw = 606 - 678 MHz
Range Bw = 626 - 698 MHz 
Range Cw = 718 - 790 MHz 
Range Dw = 790 - 865 MHz

Only Range GBw (channel 38) and Range Dw (channel 70) systems are available for purchase on the online shop. The other frequency ranges are available by special request for fixed site licence applications. Range GBw includes Channel 38 which is the most reliable solution for portable wireless microphone systems. (Please Note. Channel 38 use requires a licence. For more information please contact us or visit). Range Dw includes Channel 70 which is for legal licence-free use in the UK and Europe.

The Sennheiser G4 range of wireless microphone systems are capable of operating simultaneously, intermodulation free, on six frequencies in the licence exempt 863-865 MHz (channel 70) band. These frequencies are;

863.100 MHz
863.400 MHz
863.750 MHz
864.225 MHz
864.550 MHz
864.975 MHz
