Atlanta, GA (May 11, 2015)—Kaltman Creations LLC. has unveiled RF-ResQ (Receiver Enhancement System, an antenna signal processor intended to rescue and salvage unusable RF spectrum, substantially reduce interference and more.

“We secured the rights and ownership to advanced filtering technology that was previously used in military, nuclear plant and critical data communications,” explained president Mark L. Kaltman, “and adapted it for the UHF bands used in pro audio wireless.”

Housed in a single-rack space unit, the RF-ResQ is a standalone wireless microphone filtering system that makes use of multiple military-spec, high-Q bandpass filters. By cleaning up received RF spectrum, the unit is said to allow for closer adjacent channel spacing, potentially doubling available channel counts without sacrificing power while removing the issue of intermodulation effects and improving the reception of weaker transmissions.

RF-ResQ's onboard 8-channel antenna distribution amplifier with RF router allows its filters to adapt to various receiver and distribution configurations, providing one filter/frequency per receiver channel, which means that the user's receiver only sees its assigned transmitter frequency and nothing else. Alternatively, users can select "combined signal routing" to feed integrated receiver/distribution systems, as found in some newer digital mic systems.

RF-ResQ assigns a single, frequency-cleaned-up, bandpass filtered feed for each transmitter's frequency, and its eight amplifiers can maximize the individual RF signals up to 10 dB.

DiverseQ, the RF-ResQ's antenna diversity technology, pre-filters the antenna A/B signals in the IF stage. Installed between the antennas and receivers, the RF-ResQ works with industry-standard antennas, in analog and digital wireless mic systems in the 470 MHz to 928 MHz range. Frequency, gain and routing assignments are performed via a LAN or USB/laptop connection to the rack unit. With its router capability, the RF-ResQ can be used either as a direct replacement or in conjunction with existing antenna distribution system.
