Manual

The ATC SCS70 Pro is a high-performance 12”/ 30 0 mm 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 75 - 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.
The in-wall SCS70iW Pro features a remote mounted amplifier. This is housed within a 7U/19” rack mount chassis. Audio connection between
the remote mounted amp and subwoofer is via speaker cable terminated with Neutrik NL4 connectors. Connection to power & mute indication
LEDs is via 4-core control cable terminated with 5-pin male XLR connectors. Other features of the remote mounted amp are identical to the amp
mounted ‘on-board’.
