As wireless audio squeezes into reduced space due to the recent sale of bandwidth to Google, Verizon and others, RF audio equipment manufacturers are battling each other to push the limits of performance and features while keeping costs manageable. Sennheiser's new ew 500 G3 Series of transmitters and receivers promises to deliver trouble-free RF operation and high-quality audio.

The system is available with two transmitters — a handheld mic (SKM 500 G3), which may be fitted with a variety of capsules, and a bodypack (SK 500 G3) that accommodates several different clip-on or head-worn mics — and the ci1 instrument cable. For this review, I received the ew 572 G3 B system with receiver, transmitter and instrument cable.

ew 500 G3 systems operate in one of six UHF frequency ranges between 516 and 865 MHz. Each range offers 26 banks with 32 channels per bank (maximum) and 1,680 possible transmission frequencies. Banks 1 through 20 feature factory presets configured to cooperate without intermodulation. The remaining six banks (U1 through U6) let you select and store any frequency, but it is up to you to choose these frequencies carefully to avoid interference with other wireless devices. When used in the U.S., the ew 500 G3 is not intended for operation in the 698 to 806MHz range in deference to recent FCC developments.

Rack It and Pack It

The EM 500 G3 receiver has rear panel jacks for two antennae (in true-diversity mode), XLR and ¼-inch audio output, and DC input for the included wall wart. Front panel controls include a headphone jack with volume knob, Sync button, jog dial, on/off/standby switch, backlit LCD and infrared interface. Via the jog dial, the unit's LCD toggles between four main screens: Transmitter Parameters, Receiver Parameters, Soundcheck and Tuner. All four screens always display the receiver's operating frequency, audio level, RF level at antenna I/II, battery strength and transmitter name (which you can enter). The Transmitter Parameters screen indicates transmitter model number, sensitivity setting, mic or line input, RF power level and cable emulation status. Receiver Parameters shows receiver output level, bank/channel, EQ curve and transmitter model. Change the screen to Soundcheck and the system enters a test mode in which you can walk the performance area while the EM 500 G3 monitors maximum and minimum RF levels. This proved helpful in previewing onstage reception for dropouts.

When you switch the receiver to Tuner, it activates a chromatic tuner that is very easy to read. You can set the tuner to automatically mute the output when in use.

The SK 500 G3 transmitter offers a small but serviceable LCD and runs on two AA batteries for approximately eight hours. External provisions include a threaded ⅛-inch jack for audio input, recessed mute switch, settings button and captive antenna. On/off and Set buttons are located under the battery cover to prevent accidents during a show. I liked having the on/off switch here but some of the musicians using the system did not. Transmitter adjustments include frequency, audio sensitivity, auto-lock-on/off, Mute mode, RF power output, cable emulation, pilot tone and LCD contrast. One LED on the pack indicates power on/off/low battery, while the other LED shows peak audio level. Frequency response of the system is spec'd as 25 to 18k Hz using the line input.
