Antenna signal processor opens unusable portions of the RF spectrum while reducing interference

Saelig Company has introduced the Kaltman Invisible Waves RF-ResQ (Receiver Enhancement System) - an eight-channel antenna signal processor that can open up portions of unusable RF spectra, while substantially reducing channel interference. Working with industry standard antennas and with both analogue and digital wireless microphones in the 470MHz to 928MHz range, this solution solves many of the RF congestion issues that plague the professional audio industry. The device is housed in a rugged 1U rackmount unit, it is a standalone wireless microphone filtering system employing multiple defence-spec, high-Q band-pass digital filters. The device cleans up the received RF spectrum, allowing for closer adjacent channel spacing, potentially doubling available channel counts. It removes intermodulation effects, and improves the reception of weaker transmissions. Each receiver only sees its assigned transmitter frequency, with no out-of-band RF interference to weigh down and de-sensitise the receiver's input. The device can be remotely controlled via a network or USB, but once the desired parameters are set up, it can be locked and left alone, making it ideal in many fixed installation applications. It can also function as an eight-channel antenna distribution amplifier, with an RF router that adapts its filters to a variety of receiver and distribution configurations.
