The TX-A2 and TX-A2D are audio output transformer modules in the convenient line
of Max-TX products. Max-TX modules are the large format members of the RDL TX family, featuring the superior engineering and components
common to RDL products. The durable adhesives provided with these modules permit permanent or removable mounting. They may be rack or
surface mounted with optional TX series accessories.

TX-A2 APPLICATION: 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.

TX-A2D APPLICATION: The TX-A2D is the ideal choice in installations requiring passive isolation and level
attenuation between a professional balanced line-level stereo source and consumer equipment unbalanced inputs.

The TX-A2D is a complete unbalanced stereo line-level audio output module. The front panel provides a detachable
terminal block for connecting each channel of a balanced +4 dBu audio source. The input signals are coupled to two
front-panel gold plated phono jacks through studio-quality isolation transformers. Each output is coupled through an
attenuation network that produces a nominal -10 dBV level. Shielding is provided by the TX-A2D’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.
