Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] If a mono signal is plugged into the LEFT input only, it is automatically routed to both LEFT and RIGHT inputs.

Use the +4 dB setting for professional equipment operating at the +4 dBu standard, and use the ­10 dB setting for consumer equipment operating at the ­10 dBV standard. 2-TRACK A Trim Control This control adjusts the input sensitivity of the incoming 2-TRACK A signal by ±10 dB (unity at center detent). This allows for precise level matching between the various incoming 2-track sources, which often do not have output level controls of their own. 2-TRACK B Inputs These stereo 1/4-inch balanced/unbalanced inputs are fed by the outputs of the second external 2-track recorder. If a mono signal is plugged into the LEFT input only, it is automatically routed to both LEFT and RIGHT inputs. 2-TRACK B Level Switch This two-position switch sets the input level of the 2-TRACK B inputs to either +4 dB (balanced input) or ­10 dB (unbalanced input). Use the +4 dB setting for professional equipment operating at the +4 dBu standard, and use the ­10 dB setting for consumer equipment operating at the ­10 dBV standard. 2-TRACK B Trim Control This control adjusts the input sensitivity of the incoming 2-TRACK B signal by ±10 dB (unity at center detent). This allows for precise level matching between the various incoming 2-track sources, which often do not have output level controls of their own. DAW MIX These stereo 1/4-inch balanced/unbalanced inputs are fed by the master mix output of the DAW, usually the DAW outputs 1-2. If a mono signal is plugged into the LEFT input only, it is automatically routed to both LEFT and RIGHT inputs. DAW MIX Level Switch This two-position switch sets the input level of the DAW MIX inputs to either +4 dB (balanced input) or ­10 dB (unbalanced input). Use the +4 dB setting for professional equipment operating at the +4 dBu standard, and use the ­10 dB setting for consumer equipment operating at the ­10 dBV standard. DAW MIX Trim Control This control adjusts the input sensitivity of the incoming DAW MIX signal by ±10 dB (unity at center detent). This allows you to precisely fine tune the incoming level of the DAW MIX input so it matches the signal level of other incoming 2-track sources. PHONO These stereo RCA unbalanced inputs are fed by the outputs of a turntable with a moving-magnet cartridge (MM). These inputs have a built-in precision RIAA preamplifier that provides the equalization and gain required for a phono-level signal to return it to a proper line-level signal. This allows you to playback vinyl records and dub them to a 2-track recorder, as well as send the phono signal to the input of the DAW for archiving/ restoration/CD burning. Note: Two RCA shorting plugs are provided, which should be plugged into the PHONO inputs when they are not being used. This terminates the inputs and reduces the noise floor should you accidentally push in the PHONO INPUT SOURCE SELECT button. [. . . ] If you bring your Mackie product to an Authorized Service Center and they can't find anything wrong with it, you may be charged a service fee. 4. If the Authorized Mackie Service Center is located in another city, pack the loudspeaker in its original shipping carton. More information on packing can be found in the Service section of this manual. Contact the Authorized Mackie Service Center to arrange service or bring the Mackie product to them. [. . . ]
