Matrix 1.4 amplifier design in BTL configuration, meaning bridge-tied load where two amplifier halves drive the speaker in opposite phase, as a 1.76 MB PDF. Bridging roughly quadruples available output power into a given load, so speaker impedance limits matter. The file helps with component placement, tracing both channel halves and checking the phase-inverting stage. Open it in a PDF viewer, print at true scale if building, and confirm the minimum load rating before connecting low impedance speakers.
