The TX-TPSA1A module provides one Format-A input on the front panel. The input RJ45 connector accepts a twisted pair cable coming from one or multiple Format-A senders. This input receives and sums the signals received on the three pairs A, B and C. The summed output is fed to one of the OUTPUT pairs A, B or C selected during installation using the front-panel selector. The two remaining pairs are available for signals to pass through from other Format-A senders connected to the LOOP IN jack. Because this module drives only one pair of the output cable, the RJ45 LOOP IN jack can accept two signals and power from other Mic or Line input Format-A modules. Two single-pair senders can be connected to the LOOP IN jack, or one sender that uses two pairs.

The TX-TPSA1A may be powered from any of the RJ45 jacks, which provides power to the two remaining RJ45 jacks. The module may also be powered from an external 24 Vdc power supply connected to the DC input jack, which provides power to all three RJ45 jacks. Output voltage is protected by an automatically resetting fuse. A blue front-panel LED indicates the presence of valid power.

TX SERIES

TX Series modules are application-specific modules for the A/V and related industries. Many TX modules offer galvanic transformer isolation. Module functions include signal detection, switching, amplification, format conversion, line driving, mixing, distribution, twisted-pair sending/receiving and more. Each TX is a compact module engineered to provide higher performance and longer life than other industry products. TX modules are solid encapsulated hybrid circuits in durable industrial black plastic/steel or aluminum enclosures with clear bold white lettering for the jacks, terminal block connections, trimming controls and switches.

TX modules are constructed in two widths and heights. All TXs are the same length, have the same mounting hole configuration, and are compatible with all TX series mounting options. A complete range of mounting options is available for systems utilizing multiple TX modules. A single TX module may be mounted right where its function is needed, and are widely used in system designs with OEM or other RDL products. TX SERIES modules are designed and manufactured in the U.S.A.
