QR Code Link to This Post
The SCM25A Pro Mk2 is a compact 3-way high-performance active studio monitor loudspeaker, based around a 6.5''/164mm bass driver loaded in a 25-litre 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.
The 3-way monitor features proprietary drive units designed and manufactured by ATC. Low frequencies below 380Hz are handled by a 6.5''/164mm bass driver, mid-range frequencies between 380Hz &, 3.5kHz by the ATC 3"/75mm soft dome mid-driver. High frequencies above 3.5kHz are handled by ATC's SH25-76S Dual-Suspension 1''/25mm soft dome tweeter. This HF driver update is the primary improvement from the Mk1-to-Mk2 model. The enclosure is a ported/vented type, tuned to 32Hz and featuring a 3''/75mm diameter port with flared entry &, exit to minimise port air noise.
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 optimise 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-colour LED.
