To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance or may even cause damages. No objects filled with liquids, such as vases, shall be placed on this appliance. [. . . ] When installed in a booth or flight case, please make sure to have good ventilation to improve heat evacuation of the unit. To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance. CLEANING THE APPLIANCE: Clean by wiping with a polished cloth slightly dipped with water. Do not use volatile liquids such as benzene or thinner which will damage the unit. CAUTION: To reduce the risk of electric shock, do not remove the top cover. The lightning flash with arrowhead symbol within the equilateral triangle is intended to alert the use or the presence of un-insulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock. The exclamation point within the equilateral triangle is intended to alert the user to the presence of important operation and maintenance (servicing) instructions in the literature accompanying this appliance. For more information on connections, please refer to the next chapter. Be sure to turn off the mixer before you make changes to the different connections. PFL SWITCH This switch and indicator allows pre-fade listen of input signals through the headphone and Led meters (useful while setting gains or trouble shooting). LINE INPUT LEFT OR MONO ­ 1/4" Mono Jack Socket If the input is connected to a mono source use this connection only as the signal will automatically be routed to the right input also. 5mV (-30dBm) PAD SWITCH Operation of this switch reduces the input sensitivity by 10Db allowing it to be used with high output devices such as CD players as well as musical instruments. GAIN CONTROL The panel marking at 0dB is a true reference to 0dBm when the ­10dB Pad is engaged. Range: +10dB CLIP LED This warning light will illuminate 4dB before clipping and will remain on for a short period. For optimal input channel running level, adjust Gain Control until Clip indicator illuminates while signal peaks are present. Note: If EQ controls are altered this Gain/Clip setting will need adjustment. EQ CONTROL `LOW' This control allows 6dB of cut or boost to the low frequencies. AUX SEND 1 This auxiliary send control is `Post-fade' and can be used to control the mix of inputs being processed by effects, etc. AUX SEND 2 This auxiliary send control is `Pre-fade' and can be used to control the mix of inputs to an independent output such as monitoring. Note: The Post-fade option can only be selected by your service engineer. BALANCE CONTROL This control is used to set the stereo balance of the input signal and can pan it fully to the left or right. [. . . ] The calibration shows a suggested nominal running level, referenced `0' (10dB boost is available if required). PHANTOM SWITCH This switch is recessed to prevent accidental operation and has a corresponding red LED indicator; it should NOT be operated while the mixer is live. NOTE: It should be pre-selected during setting up with the main output faders and MIC input gain controls down. Some microphones that do NOT require phantom supply may not operate or are damaged ­ check instructions. [. . . ]
