atc spa2-150 power amplifier for sale in the usa at atcspeakers.com
 ATC SPA2-150
  • The SPA2-150 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 utilizes 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 preamplifier.

The output stage of the SPA2-150 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. Remote control of the SPA2-150 is possible using the SCA R remote controller, or any other standard RC5 device. High quality connectors are used throughout including massive WBT terminals.

Styling is complementary to the SCA2 with high quality peened stainless steel covers atop naked aluminum machined corners. A dark grey textured finish is also available to special order.
