ATC SCM25A Pro mkII (Pair)

ATC SCM25A Pro MkII

The ATC SCM25A Pro MkII is a compact 3-way active ported studio reference monitor with a 6.5"/164mm bass driver loaded in a 25-litre vented cabinet and an integrated 235W amplifier, well suited for smaller to medium studios.

The 3-way design features the ATC SM75-150 Soft Dome mid-range driver  (3"/75mm) which handles mid frequencies between 380Hz and 3.5kHz.

The ATC SCM25A Pro MkII has all ATC-designed and produced proprietary drive units. A 6.5"/164mm bass speaker handles low frequencies below 380Hz.

Updated Tweeter Design

In addition, the new ATC SCM25A Pro MKII has ATC's SH25-76S Dual-Suspension 1"/25mm soft dome tweeter which handles high frequencies exceeding 3.5kHz. This HF driver upgrade is the crucial difference between the Mk1 and Mk2 models. The update with ATC’s latest SH25-76S ‘Dual Suspension’ tweeter, extends the high-frequency response also providing a reduction in distortion.

The enclosure is a ported/vented design tuned to 32Hz and has a 3"/75mm diameter port with flared entrance and exit to reduce port air noise.

Class A/B Amp

A 3-way class A/B amp pack installed in the back of the cabinet actively drives the SCM25A Pro Mk2. Each driving unit is equipped with its power amplifier. The audio input is a 3-pin female XLR on the back panel, and the power is an IEC mains power inlet. The user may adjust input sensitivity and bass' boost'. Crossovers are 4th order Linkwitz-Riley with all-pass filters to improve tone accuracy, imaging, and on and off-axis frequency response. To reduce amplifier' hard-clipping,' FET peak limiters are added. A front-panel-mounted bi-colour LED indicates that the power and limiter are functioning.
