The Sennheiser SKM 500 G4 is a handheld wireless microphone transmitter compatible with the EM 300-500 G4 wireless receiver. It features an interchangeable microphone capsule design and is offered without a capsule included, so you can choose the one that best fits your application. The transmitter operates on a wide 50 MHz UHF tuning range with 2000 selectable frequencies available. It provides up to 8 hours of operation on two AA batteries, with a transmission range up to 330 feet and a selectable 10/30/50mW RF power output for overcoming interference in difficult RF environments.
The rugged, all-metal SKM 500 G4 offers an adjustable gain which allows you to set the optimal level for your voice, and the controls can be locked out to prevent accidental changes. When the Sync function on the receiver is engaged, the transmitter and receiver quickly link to the same frequency via infrared. A backlit LCD displays essential information and provides fast menu access.
The unit can be powered via two AA batteries or a rechargeable BA 2015 Accupack battery (available separately). With the LA 2 charging adapter and the L 2015 quick-charging unit (both available separately), the Accupack can be recharged without removing it from the transmitter.
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.
In addition to the EW 300/500 receiver, the SKM 500 G4 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 systems.
