Rio Rancho, NM (June 27, 2018)—The FCC recently expanded the 941-960 MHz frequency band; aiming to make the most of that space, Lectrosonics has unveiled a number of Digital Hybrid Wireless microphone products, focused on ENG and field/production sound, that will operate in the new band.
The 944-952 MHz band was previously reserved for use by licensed broadcasters for Studio Transmission Links (“STL”s) along with some wireless microphones and IFB (Interruptible Fold-Back) systems. This band has now been expanded by the FCC to include specific ranges between 941 and 960 MHz. Eligibility for this band has also changed, and is now open to all Part 74 Licensed wireless microphone operators. This band is the same throughout the US.
Lectrosonics’ new products include the SRc-941 dual-channel modular portable receiver ($3,170); the SMV-941 ($1,866) and SMQV-941 ($1,975) miniature belt pack transmitters, the HMa-941 plug-on transmitter ($1,625), and the HHa-941 handheld transmitter ($1,800, not including capsule head).
All transmitter models in this band offer 50 and 100 mW RF power settings, but otherwise are functionally identical to the same units in the traditional UHF frequency blocks and bands. Likewise, all 941 units are compatible with the accessories for the same models in different frequency ranges, including external powering, audio connectors, microphones, belt clips and mounting options. The transmitters have a circular isolator in the output stage for additional intermodulation prevention, allowing closer spacing of RF carriers.
The specific tuning ranges for these products are 941.525 – 951.975 MHz, 952.875 – 955.225 Mhz, and 956.475 – 959.825 MHz. Parts of these bands are shared with MAS (Multiple Access Systems) and some fixed microwave devices.
Operators using the 941-960 band should always coordinate their frequencies with the local office of the SBE (Society of Broadcast Engineers), whenever possible, and take care to select frequencies that are least likely to result in interference with other licensees in the same area. These products all meet the new spectral mask regulations imposed by the FCC and in effect for all new wireless microphones after October, 2018.
