This PKI 2225 Professional Pocket Receiver has been developed for the reception of our various PKI transmitters. With its pocket-size dimension and high input sensitivity PKI 2225 leaves nothing to be desired. It is powered by a common 9V block battery which allows 8 hours operating time. The extraordinary high input sensitivity of 0,25μV at 12dB provides longest possible operating range between transmitter and receiver. The PKI 2225 Professional Pocket Receiver is available with digital recorder (PKI 2105), with and without loudspeaker in UHF range and 3 channels each.
