TX-8A

RDL TX-8A - 4 Ohm / 8 Ohm Input Interface

The RDL TX-8A is a mono audio interface designed to convert speaker-level signals from 4Ω or 8Ω amplifier outputs into line-level signals, with selectable balanced or unbalanced output. It provides galvanic isolation and high-quality signal transmission, enabling safe and accurate integration with mixers, line-level amplifiers, or audio processors.

Supporting input power levels from 0.5W to 400W, the TX-8A features a front-panel LEVEL control for output adjustment between -10 dBV and +4 dBu. A bifilar-wound, studio-grade audio transformer ensures wideband response, low distortion, and excellent clarity. Its superior low-frequency performance makes it ideal for feeding subwoofer amplifier inputs.

The module includes barrier block connections for input and output, and its compact design allows flexible mounting options - on rack sides, front or rear rails, using RDL mounting accessories.

Functionality:

• converts 4Ω / 8Ω speaker-level signal to line-level output
• adjustable output level: -10 dBV / +4 dBu
• supports input power from 0.5W to 400W
• selectable balanced or unbalanced output
• galvanic isolation - studio-quality audio transformer

Features:

• bifilar-wound transformer - clean, wideband signal
• excellent low-frequency response - ideal for subwoofers
• barrier block terminals - easy signal and ground connection
• compact housing - versatile mounting options
• output ground connected to metal chassis - stability and safety

RDL TX-8A is a reliable solution for professional AV installations requiring precise speaker-to-line signal conversion with high audio quality and galvanic isolation.
