• Description

As with all ATC products, acoustic performance has been the primary goal and the design uses drive units and amplifier technology from the larger SCM series loudspeakers.

The drive units all use large diameter, under-hung voice coils for excellent dynamic range and linearity. The mid-range dome is the company’s world renowned soft dome, and the bass driver is a hand built, in house, using a carbon-paper cone with high excursion capability.

On-board amplification is constructed around the company’s class A/B Mosfet output stage delivering 150W to the bass driver, 60W to the mid and 25W to the high frequency driver, with all three stages fed by 4th order critically damped crossover filters with phase compensation.

An added feature of the compact design is that it can be rack mounted using an optional rack mounting kit, making it ideally suited to broadcast and outside broadcast applications.

The SCM25A Pro comes with a 6 year product warranty.
