OverviewThe SCM25A Pro Mk2 is a compact 3-way high-performance active studio monitor loudspeaker, based around a 6.5/164mm bass driver. The monitors combination of exceptional mid-range clarity, high output, extended bass response and modest size makes it ideal for nearfield monitoring in a wide range of critical applications.The latest Mk2 version is updated with ATCs latest SH25-76S Dual Suspension tweeter, extending the high-frequency response along with a reduction in distortion. These improvements ensure faster decision making and outstanding translation outside the studio.Key Features 3-way design featuring ATC SM75-150 Soft Dome mid-range driver. Wide dispersion vs frequency for excellent stereo imaging over a large listening area. ATC discrete MOSFET class A/B amp-pack delivers high dynamic range in combination with very low distortion and an extended HF bandwidth. 4th order active crossovers with all-pass phase compensation ensure outstanding driver integration. Input sensitivity and bass lift user controls. Hand-built in England and covered by a 6-year warranty.Acoustic SpecificationsDrive Units Bass: 1 x SB50-164SC 8OMid: 1 x SM75-150 16OHF: 1 x SH25-76S 6O CompactLow Frequency Cut-off: 47Hz (-6dB, anechoic).High Frequency Cut-off: 25kHz (-6dB).Max SPL: 109dB continuous / 115dB peak (Per pair, IEC Weighted Pink Noise, 1m, anechoic).Sensitivity: +4dBu ref 92dBC (Bass Boot 0dB, Input Sensitivity 1V, Pink noise).Electronic SpecificationsBalanced Input: 1 x Rear Panel Mounted Female XLR, pin 2 hot.Input Impedance: 20kO (differential).Input CMRR: >82dB (10kHz).Input Sensitivity: 2.2dBu / 1Vrms for full powerInput Sensitivity Control: Continuously Variable from 2.2dBu 8.2dBu / 1Vrms - 2Vrms (-6dB)Bass Boost Control: Continuously variable from 0dB to +3dB.Crossover Filters: 4th Order Linkwitz-Riley at 380Hz and 3.5kHz.Frequency Response: <2Hz to >200kHz (-3dB).Amplifier type: Grounded Source MOSFET based Class A/B, convection cooled.Output Power: Bass 150W (8O), Mid 60W (8O), HF 32W (6O)THD+N: <0.003%/-92dB (1kHz, 1dB below rated power, 90kHz BW)Limiter: ATC Active FET Momentary Gain Reduction, limiter active indicated via front panel LED.Mains Input: 220-230V or 115V Factory set.
