Symphony S6 Full-Range Class D Amplifier

Engineered to be the do-it-all 6-channel, the Symphony S6 can run an entire daily system, a high-fidelity 3-way active front stage, or a loud pro-audio setup — all while giving you three independent pairs of customizable signal outputs for precise tuning. The latest Symphony platform packs more power density, a new thermally-optimized heatsink, and pro-grade controls in a compact footprint.
