The TX-AT1S is the ideal choice in many applications requiring studio quality transformer coupling between balanced audio equipment and a balanced line in environments where harmful impulses and unwanted rf pickup are likely. The TX-AT1S is a single-channel (mono) module featuring barrier block connections for the input and output. A studio-quality audio transformer couples the audio input to the audio output. A common ground terminal is connected to the TX-AT1S metal support structure. The TX-AT1S incorporates the latest in surface mount, all solid-state (no gas tube), transient suppression technology coupled with ferrite high frequency suppression. A 1:1 audio transformer provides galvanic isolation. The audio transformer has 600 Ohm primary and secondary bifilar windings, though is optimized to be driven from a low-impedance source into a bridging load. The primary and/or secondary may be wired unbalanced, providing conversion between balanced and unbalanced audio lines. The TX-AT1S 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-AT1S’s compact size permits mounting in a variety of spaces and in various locations in equipment racks. The TX-AT1S 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-AT1S individually, or combine it with other RDL products as part of a complete audio/video system.
