The ATC Loudspeaker SPA2-150 is a high quality power amplifier designed to partner ATC passive monitors and other loudspeaker systems.

It is capable of output power considerably in excess of specification and incorporate the same gain reduction and loudspeaker protection circuits as ATC's active monitors. This ensures that even when working at very high levels
the amplifier is held back from clipping so improving the subjective performance and protecting the loudspeakers from damage.
The amplifier incorporates switch selectable balanced and unbalanced signal inputs on XLR and RCA phono sockets respectively. Loudspeaker output connections are made through two pairs of WBT connectors.

The SPA2-150 can be switched into and out of Standby mode by either ATC remote handset and incorporate comprehensive performance monitoring and feedback through a front panel display.
