All HME DX Series wireless intercom systems now feature Spectrum Friendly™ technology for interference-free operation in the increasingly crowded 2.4GHz frequency band. This new technology enables broadcast and theatrical production crews to avoid emerging frequency conflicts by designating the 2.4GHz operating frequency range: low-, high-, or full-band. While generally not a problem when separated, multiple applications and multiple users of the same applications in close proximity can result in additional risk for trouble-free operation. The new technology further ensures that HME products do not add interference to the spectrum for other essential wireless services in the vicinity, such as DMX-controlled lighting.
