The ATC SPA2 150 power amplifier uses a grounded source output stage to deliver over 150W, driven by a buffer based on the discrete gain block which enables the SCA2 pre-amplifier to deliver such astonishing performance figures. Used in this way to drive the FET output stage, distortion components are more than 95db down under any conditions, ensuring totally clean and transparent sound with the effortless dynamics for which ATC is justly famous.
Input to the amplifier utilises a similar discrete gain block and offers both balanced and unbalanced capability for universal system matching. This input buffer, which completely eliminates integrated circuits, achieves the same levels of transparency as the famous ATC SCA2 pre amplifier.
The output stage of the ATC SPA2-150 power amplifier is continuously monitored by microcomputer and a carefully programmed limiter prevents amplifier clip and protects loudspeaker drive units. Front panel indication of limiter operation is provided separately for each channel. Additionally the amplifier is monitored for over-temperature and DC offset.
When compare to ATC P1: While the P1 and SPA2-150 are rated at the same power of 150w/ch however the quality of the SPA2-150′s 150 watts are significantly better than the P1′s. Therefore the SPA2-150 performs better and drive speakers more effectively than the already superb P1. The fit, finish and build on the SPA2-150 is also better than on the P1.
