SA-2

Power Amplifier

While many contemporary amplifiers waste 50% or more of the power they pull from the wall as heat, the SA-series amplifiers run at approximately 90% efficiency. As a result, more power is available for the loudspeaker, and less is wasted as heat in your room.

The high efficiency of the SA-series design also means that the amplifiers can be placed in close proximity to each other, as in an equipment rack, without undue overheating.
