Sonance SBA-1 Stereo Bridging Adapter (Bridge Two Amplifiers Together) Audio

New, unused, uninstalled item. Comes complete with the device, instruction sheet and box. Useful and fun to experiment with. For example, two stereo 100W per channel amplifiers (if compatible) become a single mono channel aprox. 350W amplifier. BASIC CONCEPT SBA-1 Stereo Bridging Adaptor: The SBA-1 essentially transforms two, 2-channel amplifiers into two mono bridged amplifiers, each with approximately 3-1/2 times the power of a single stereo channel! This active device accepts left and right stereo line-level signals from any variable line-level source (e.g., receiver, preamplifier). It then creates output signals that are available as left channel non-inverting (+) and inverting (-) output(s), and right channel non-inverting (+) and inverting (-) output(s) through dual gold RCA jacks.
