[. . . ] IEC RECEPTACLE - Check voltage selector switch before connecting power. Connect to 115 Volt AC / 60Hz power source, rated for 200 WATTS or 230 Volt / 50Hz rated for 200 WATTS. Only use the supplied power cord or an IEC approved power cord with a safety ground pin. AMPLIFIER HEATSINK- The heatsink provides essential cooling to the amplifier inside the SUB 8 Universal MK III. Please ensure that proper air circulation is available for proper cooling. VARIABLE CUTOFF FREQUENCY CONTROL KNOBS - These controls are for adjusting the dual 24dB per octave low and highpass filters. The cutoff frequency can be adjusted from 50Hz to 160Hz. It is recommended that the SUB 8 Universal MK III filters be set one octave above the natural roll off of the nearfield monitors that are being used with the SUB 8 Universal MK III. To activate these variable filters, the VARIABLE / SAT 5 FILTER SWITCH - must be in the up position (VARIABLE). For more information see item 10 on page 4 [Quick Setup / with Universal MK III filter instructions]. SUB GAIN - This knob controls the input sensitivity of the subwoofer amplifier only. When set to the reference position a 100mV signal at the input equals 90dB output at a meter. SUB Out - This balanced XLR output can feed additional subwoofers for increased bass performance and should be connected to the SUB IN of an additional Blue Sky SUB 8 / SUB 8 Universal MK III. The output contains the summed low passed subwoofer output and the SUB IN audio. SUB IN - This XLR input can be connected to either the subwoofer output of an external bass-management controller, or the "daisychain" output of a SUB 8 / SUB 8 Universal MK III. This input is fullbandwidth (up to approximately 200Hz) and does not use a low pass filter. Page 7 7. Expanded Calibration Guide move the output faders.
