The Electro-Voice R300-HD is a cost-effective, all-metal handheld wireless 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-HD includes the R300 antenna-diversity receiver and the HT300 handheld microphone transmitter with a PL22 cardioid, dynamic capsule. The system has a 150' operating range and features 32 pre-progammed frequencies to scan for optimal transmission, along with removable antennas that allow the user to rackmount the receiver (with separately available rackmount kit and antenna cables).

The ClearScan feature on the R300 receiver 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.

A: Yes, the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System is compatible for use with the Panasonic AG-UX90 UHD 4K Professional Camcorder.

Q: 3. Is there some sort of adapter I can use to plug this into a laptop using USB?

The Sennheiser kit comes with a CL-100 cable that will connect via XLR to the Focusrite device, which includes a USB cable to connect to the laptop.

Q: 6. It this model's frequency a good fit for recording in NYC?

A: Yes, frequency band A1 can be used in New York City. However, channels 14, 15, and 16 will be blocked for public safety deployment.

Q: 7. The manual says to set AF Out on the receiver to +18 dB. Is this true? Why not 0db?

A: In general, Camera preamps are not the best quality. +18db ensures that you will need the least amount of preamp gain possible, which will maximize the quality you capture with the camera.

Q: 8. Does the G4 system work with the Sanken COS-11D?

A: Yes it does. The Sanken mic is far better than the one that comes with the kit and it is perfectly compatible.

Q: 9. Is the power supply 110~220v automatic?

Q: 10. Does this work with a Panasonic G85 or G95 camera?

A: Yes, the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System would work with the Panasonic Lumix G85 Mirrorless Camera, as the camera has the necessary 3.5mm microphone input connection. The EW 112P G4 includes an adapter to mount the receiver onto the camera shoe, as well as the appropriate cable to connect the receiver's output to the camera's input. It does not appear that the Panasonic Lumix G95 Mirrorless Camera has the necessary 3.5mm microphone input connection, however.
