You Need The TX-AFC1F!

The TX-AFC1F is part of the group of versatile Max-TX series products from Radio Design Labs. 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 the TX-AFC1F permit
permanent or removable mounting. The TX-AFC1F may be rack or surface mounted with optional TX
series accessories.

APPLICATION: The TX-AFC1F is the ideal choice in many applications requiring studio quality
transformer coupling between a balanced audio source and unbalanced equipment.

The TX-AFC1F is a single-channel (mono) module featuring a female XLR input and phono jack output. A
studio quality audio transformer converts the audio input to unbalanced. An integral pad is set to produce
an output level of –10 dBV for an input level of +4 dBu balanced. The XLR shield (Pin 1) is connected to
the output phono jack ground. The TX-AFC1F bridges the input signal and is optimized to feed a 10 k
Ohm load.

A studio quality audio transformer provides format conversion and galvanic isolation. The TX-AFC1F
delivers the wideband audio, ultra-low distortion, audio clarity and headroom common to studio equipment
in a module suited to both studio and general-purpose audio installations.

The TX-AFC1F’s compact size permits mounting in a variety of spaces and in various locations in
equipment racks. The location of the input/output jacks permits high density mounting against flat
surfaces while maintaining accessibility to the connectors. The TX-AFC1F may be mounted where
needed, to rack sides or in an equipment rack (either the front or rear rack rails) using a variety of
available RDL mounting options. Use the TX-AFC1F individually, or combine it with other RDL products
as part of a complete audio/video system.
