ATC LOUDSPEAKERS SCM45A Pro | 3-way Active Studio Monitor | Black

SCM45A Pro

Mid-Size High Performance Active 3-Way Studio Monitor

The SCM45 is a three way active loudspeaker. Active units have a built in three way Amplifier with frequency, gain and phase correction which has been individually optimised at the ATC manufacturing facility. Adjustment of input sensitivity and bass boost are available to the user via controls on the rear panel of the unit.

• Ideally suited to:
  • critical near-field listening applications in all control rooms 
  • LCR surround monitoring in medium control rooms
  • surround channels in medium-to-large contol rooms.
• ATC hand built 6.5˝/164mm carbon-paper cone bass driver.
• ATC 25mm/1” Dual-Suspension ‘S-Spec’ Tweeter
• Discrete MOSFET class A/B tri-amp pack with 150W/60W/25W continuous power output
