SIGMA MODULE M410 MIC/LINE INPUT--OPERATING SYSTEM

mono input with access to all console outputs plus its own direct post fader buffered output. The module occupies one
standard frame position and may be used with all the fader options.
Audio connections are via industry standard panel hardware and are an integral part of the module construction. These
