ATC Loudspeakers SCM25A PRO Mk2 Compact Active 3-Way Monitor - Pair #9900/9901 (Used)

The ATC SCM25A PRO Mk2 has been upgraded with ATC’s hand made proprietary SH25-76S Dual Suspension Tweeter, extending the high-frequency response with a reduction in distortion. Like the original SCM25A, the upgraded Mk2 is a compact 3-way high-performance active studio monitor loudspeaker, based around the hand made proprietary ATC 3"/75mm soft mid-dome driver and 6.5"/164mm bass driver loaded in a 25-liter vented cabinet. The monitor’s combination of exceptional mid-range clarity, high-output, extended bass response and modest size make it ideal for nearfield monitoring across a wide range of critical applications.

These 3-way monitor features drive units designed and manufactured by ATC, and are only available in ATC Loudspeakers.

The SCM25A Pro Mk2 is actively driven by a 3-way class A/B amp pack mounted in the rear of the cabinet. Each drive unit has its own dedicated power amplifier. Audio input is via a rear panel mounted 3-pin female XLR and power via an IEC mains power inlet. There are user controls for input sensitivity and bass ‘boost’. Crossovers are 4th order Linkwitz-Riley and all-pass filters are included to optimize the phase response through the crossover regions, improving the tonal accuracy, imaging, on and off-axis frequency response. FET peak limiters are included to reduce amplifier ‘hard-clipping’. Power ‘on’ and limiter ‘active’ is indicated by a front panel mounted bi-color LED.

FEATURES:

• High frequencies above 3.5 kHz are handled by ATC’s SH25-76S Dual-Suspension 1”/25mm soft dome tweeter - the primary improvement from the original SCM25A model
• Mid-range frequencies between 380 Hz and 3.5 kHz by the ATC 3"/75mm soft dome mid-driver
• Low frequencies below 380 Hz are handled by a 6.5"/164mm bass driver
• The enclosure is a ported/vented type, tuned to 32 Hz and featuring a 3"/75mm diameter port with flared entry & exit to minimize port air noise
