CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN ATTENTION: RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE The symbols shown above are internationally accepted symbols that warn of potential hazards with electrical products. The lightning flash with arrowpoint in an equilateral triangle means that there are dangerous voltages present within the unit.
C223 2-WAY, 3-WAY CROSSOVERS FRONT PANEL Stereo 2-way mode In 2-way stereo mode the controls are marked BELOW the horizontal red line. Channel one and channel two functions are identical in the stereo mode. LEDs are disabled for controls which are non-functional in this mode.
C223 2-WAY, 3-WAY CROSSOVERS Mono 3-Way Mode In 3-way mono operation the controls are marked ABOVE the horizontal Red line. Front panel controls not described in this section are not active in mono 3-way mode. LEDs are disabled for controls which are nonfunctional in this mode. [1] INPUT GAIN Controls the INPUT level with +/- 12dB of gain. [9] LOW CUT Switch for selecting the 40Hz high pass filter. An LED indicates the selection.

C223 2-WAY, 3-WAY CROSSOVERS The other feature accessed on the back panel is "low frequency summing". This is useful with systems that utilize mono subwoofers. Activating the LF sum switch "sums" the low frequencies of both the left and right inputs. The sum is sent to channel one's low output marked "LF SUM", while channel two's low output is not used, and channel two's phase invert LED is disabled, indicating it is not operational in "LF SUM" mode.
