The ATC SC S70 Pro is a high-performance 12 ”/ 3 0 0mm active subwoofer, designed from the ground up to deliver the exceptional levels of performance required to partner ATC’s active monitors. Its performance and features make it ideally suited to use within stereo, multi-channel surround and immersive audio systems.The sub features a sealed-box (infinite baffle) design, chosen for its balance of sub-bass extension and driver control. The cabinet is heavy and inert to minimise cabinet colouration. For situations requiring flush mounted/in-wall subwoofers, an in-wall variant, the SCS70iW Pro is available which features a shallower cabinet and a 7 U /19 ” rack mounted remote amplifier. The subwoofer cabinet features a panel mounted in its front face with two LEDs to indicate ‘on’/’limit’ and ‘mute’.
The S S 7 5 - 314 S C driver employed in the SCS70 Pro has been meticulously optimised to reproduce the lowest 3 octaves of the audio band within the design of the SCS70 subwoofer system. It employs a short-coil operating in an exceptionally long magnetic gap to deliver high sound pressure levels with very low levels of distortion.
The SCS70s convection cooled amplifier is mounted in the rear of the SCS70 Pro cabinet. Two balanced inputs enable connection to mono or stereo sources. A pair of buffered, un-filtered balanced outputs are provided for connection to partnering active monitor loudspeakers or to ‘daisy-chain’ multiple subs. 21d B range of gain control, three low pass frequency settings, polarity switch and a 18 0 degree continuously variable phase setting allow the user to optimise the subwoofer for use with a very wide range of partnering loudspeakers. The low pass filter can also be set to ‘Off’ (320Hz) should the user wish to use the SCS70 Pro with external processing. The amplifier features fault monitoring of amp panel temperature and power amplifier D.C offset either fault condition is indicated via illumination of a single red LED mounted on the amp panel.
When in use, the subwoofer output can be muted using a single latching footswitch connected via a ¼”/6.35mm jack. The mute function does not affect the outputs to the primary monitor loudspeakers, only the output from the sub itself. Additional subs cab be muted using the same single footswitch via connection to the mute ‘Thru’ jack.
