Convert high-level speaker wire signals into clean, line-level audio outputs with the Russound ADP-1.2 speaker-to-line-level adapter. Purpose-built for custom AV integrators, multi-room audio installations, and commercial retrofits, this passive impedance-matching adapter allows amplifiers or receiver speaker outputs to feed powered subwoofers, secondary power amplifiers, or line-level matrix inputs without distortion or overload.
The ADP-1.2 features precision resistive attenuation networks that step down high-voltage speaker signals to standard RCA stereo line-level signals while maintaining signal purity and full frequency bandwidth. Its passive, transformerless design requires no external power source, ensuring clean integration into structured wiring cabinets, media centers, or equipment racks. Heavy-duty screw-terminal inputs accommodate up to 14 AWG speaker wire, making terminations fast and secure on the jobsite.
Key Features & Highlights
High-to-Low Signal Conversion: Converts amplified speaker outputs (up to 250W per channel) to line-level RCA pre-amp signals.
Passive Operation: Operates cleanly without requiring external DC power or AC wall adapters.
Precision Signal Attenuation: Steps down high-voltage signals linearly to prevent clipping, hum, or pre-amp saturation.
Full-Range Frequency Response: Preserves total acoustic bandwidth (20 Hz – 20 kHz) for accurate audio reproduction.
Removable Screw Terminals: Snap-in connector blocks accept up to 14 AWG speaker wire for effortless installation.
Compact Inline Footprint: Lightweight enclosure hides easily behind AV receivers, inside cabinets, or within equipment racks.
