The DX340ES is a slightly modified version of the DX300ES and includes better RF filtering, lost packet concealment and enhanced 7kHz wideband audio.
Triple diversity design transmits the audio signal twice, at different times and frequencies, and selects the strongest signal from two different antennas.
Multiple MB340 Base Stations can be connection together over the MB340ES-RJ45 connector cable. MB340ES-RJ45 provides up to 7-foot of connectivity between base stations.
Auxiliary Input and Output ten-pin terminal strip connector makes it easy to configure to operate with almost any base radio or 4-wire intercom. External interface required to connect into 2-wire systems.
