Related Questions and Answers

Q: 1. What are the advantages/disadvantages of using the 216mhz vs 72

A: The 216 MHz system would be great for large coverage areas. With the right antenna they can reach up to about 3,000 ft line-of-sight. You would only be able to have about 3 transmitters in the same area using 216 MHz, though. 72 MHz has a smaller range of about 1,000 ft line-of-sight, but you would be able to have about 7-8 transmitters in the same area. This tends to be the more popular frequency, as well.

Q: 2. What is the best frequency band for the US West coast?

A: There is no one specific frequency band that is best for the US West Coast. The Sony UTX-P40 Wireless Plug-On Transmitters for the UC14 and UC25 bands each have 2,772 auto-scan frequencies within the band. This means that there are 2,772 individual frequencies that the wireless microphone system scans to automatically select the clearest one to use for transmitting audio. The UC90 band has 654 auto-scan frequencies within the band. The UTX-P40 Transmitter will need to be used with a compatible Sony wireless microphone receiver that operates on the same frequency band.

Q: 9. Will this work with a Canon eos 4000d and a voking III FLASH?

A: Due to the lack of a center pin in the hot shoe of certain Canon cameras (e.g. 4000D, T100, SL3, and T7, among others), the Pluto RF Transmitter & Receiver for Canon Cameras (B&H# PLRFTRCAN) will not receive the sync signal from the camera to trigger a flash on (in the hot shoe of the transmitter) or off (in the hot shoe of the receiver) of the camera. If an economy-priced option is desired then we recommend the Godox X2 2.4 GHz TTL Wireless Flash Trigger for Canon (B&H# GOX2TC) for mounting in the hot shoe of any of the aforementioned cameras or any other Canon camera with a pre-2022 hot shoe, or even in those of the most modern version of the Canon hot shoe on a camera such as the Canon EOS R50 with the Canon AD-E1 Multi-Function Shoe Adapter (B&H# CAOCSAADE1). The Godox X1R-C TTL Wireless Flash Receiver for Canon (B&H# GOX1RC) would be added to receive the signal off camera.
