The TX-A2 is the ideal choice in installations requiring passive isolation and level attenuation between a professional balanced line-level mono source and consumer equipment unbalanced inputs.

The TX-A2 is a complete unbalanced line-level audio output module. The front panel provides a detachable terminal block for connection of a balanced +4 dBu audio source. The input signal is coupled to two front-panel gold plated RCA jacks through a studio-quality isolation transformer. Each output is coupled through an attenuation network that produces a nominal -10 dBV level. Both output jacks may be used to feed two mono equipment inputs or one stereo input. A single output jack may be used for mono. Shielding is provided by the TX-A2's heavy duty aluminum enclosure.

Wherever professional format audio signals need to be converted to an unbalanced line level, the TX-A2 and TX-A2D are an ideal choice. Use them individually or in conjunction with other RDL products as part of a complete audio/video system.

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.
