DOUK AUDIO SP102 Audio Speaker / Amplifier Selector Switch

The Douk Audio SP102 is a passive 2-channel audio selector designed to switch or compare two amplifiers or two pairs of speakers within a single system, in either 2-input / 1-output or 1-input / 2-output configuration. It handles up to 200W per channel, relying on a fully mechanical architecture requiring no power supply to preserve signal integrity and avoid any alteration introduced by active circuitry, ensuring lossless and interference-free transmission.

Intended for Hi-Fi setups requiring direct comparisons or rapid switching, it combines complete channel isolation with a dedicated A/B selector, allowing instant switching between different electronics — Class A, B, D or tube amplifiers — or between multiple speaker pairs, while minimising connector wear and maintaining stable, consistent reproduction.
