The Electro-Voice R300-E is a cost-effective wireless omnidirectional headset microphone system well suited for tabletop use, or as part of an AV installation, in small- to medium-sized conference centers, educational facilities, and performance spaces.

The R300-E includes the R300 antenna-diversity receiver along with the BP-300 bodypack transmitter and an HM3 headworn condenser microphone. The mic's forgiving omnidirectional polar pattern picks up sound from all around the capsule, helping to ensure consistent levels even when the talent turns away from the capsule. The receiver has a 150' operating range and features 32 pre-programmed frequencies to scan for optimal transmission, along with removable antennas that allow the user to rackmount the unit (requires mounting kit and antenna cables—available separately).

The ClearScan feature on the R300 automatically searches for the ideal operating frequency, while the EZ Sync button locks the transmitter to the correct channel via infrared. The system's antenna-diversity technology helps to reduce noise and interference by comparing the incoming signals on the two antennas and using the stronger one. The receiver features both 1/4" phone and XLR outputs on the rear, and a power supply is included. The HT300 transmitter operates for up to 14 hours on a pair of AA alkaline batteries.

Q: 9. EV Technical Support was cluelesss and told me they don't sell this in C Band in the US and that there are no issues with 600mhz soon being obsolete. Their Frequency Finder webpage says there are no useable frequencies for this mic in the NYC area. Anybody using this wireless mic system with C Band in the NYC area?

A: The Electro-Voice R300-HD is available in the C-band (516MHz-532MHz), and currently can be operated in the NYC metropolitan area.

Q: 10. What will happen when starting 2020, most of the 600 mhz range will no longer be available to wireless mic users?

A: The Electro-Voice R300-HD handheld wireless microphone system in frequency band C operates below the 600 MHz range; 516-532MHz. You will have no immediate need to change your system. Here is some more information directly from the FCC.gov website: Wireless microphone users, whether licensed or unlicensed, may continue to operate on a secondary basis in the bands that continue to be available for and used on a primary basis by broadcast television (TV channels 2-36). Use of these TV band frequencies, which fall below 608 MHz, remain available for wireless microphone use after the incentive auction. FCC 15-100, FCC 15-99 Licensed wireless microphones may also operate on the specific frequencies in the 600 MHz duplex gap (652-657 MHz), and unlicensed wireless microphones may operate on a portion of the 600 MHz guard band (614-616 MHz) or a portion of the 600 MHz duplex gap (657-663 MHz). FCC 15-100, FCC 15-99, DA 17-314.
