Further information:       I'd forgotten how heavy this amplifier was until moving it out of rack recently.  You want quality watts...then this is the amp for you quite simply!

 

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.

Construction is Twin-mono, with separate high capacity mains transformers for each channel. The FET output stage is very fast and layouts follow best RF practice with direct signal paths and direct low impedance power supplies.

High quality connectors are used throughout including massive WBT terminals
