ATC SCS120 Pro 15in Active Subwoofer - Free Standing

About: ATC SCS120 Pro 15in Active Subwoofer - Free Standing

The ATC SCS120 Pro is a 15” (375mm) active subwoofer, designed to deliver the exceptional levels of performance required by audio and music professionals and support ATCs range of active monitors. The subwoofers high dynamic range makes it ideally suited to critical monitoring in larger rooms and when paired with larger mid-field and main-monitors and across a very wide range of applications and audio formats including stereo and multi-channel surround plus immersive audio formats such as Dolby Atmos.

• High performance sealed box design using 15” (375mm) ATC proprietary sub driver.
• Ideal partner to the SCM45A/SCM50A/SCM100A/SCM110A/SCM150A/SCM200A/SCM300A Pro monitors.
• Suitable for use in stereo, surround and immersive audio applications.
• On-board 300W convention cooled discrete MOSFET class A/B amp.
• 2x balanced XLR inputs
• 2x balanced XLR outputs (un-filtered/processed).
• User adjustable gain, low pass frequency, polarity and phase settings.
• Remote sub muting via latching footswitch*
  • * Footswitch supplied separately, latching type, ¼”/6.35mm jack connection.
• In-Wall variant with remote amplifier also available – the SCS120iW Pro.
