Kappa 102a F E A T U R E S The Kappa 102a is a 2-channel power amplifier that offers stereo, bridged-mono, or tri-mode operation, and is rated at 100 watts (rms) per channel into a 4-ohm load. In a bridged-mono configuration, it can deliver up to 300 watts (rms) for the same load.
NOTE: For simplicity, Figures 1 through 3 do not show power, Figures 1 through 3 show how to configure the Kappa 102a remote, and input connections. for stereo, bridged-mono, and tri-mode operation.
