User manual RANE MM 8X

[. . . ] OPERATORS MANUAL MM 8x MIXER QUICK START Here are a few basic "plug and play" steps to get you performing. If you are a first time DJ mixer user, please do yourself a favor and at least read this section. Begin by making sure your amplifier is off before making connections. The MM 8x has all unbalanced connectors, except for the 1/4" balanced main outputs and XLR microphone inputs. [. . . ] Taking the least amount of gain at the output ensures that the system doesn't have to amplify the unavoidable noise generated by the input buffers and summing amplifiers. Unity gain for Line Inputs is achieved with the faders positioned at the "0 dB" marking. HEADPHONE SYSTEM Depending on the position of the Pan control, a mix of stereo Cue or stereo Master is heard through the headphones. Fully counterclockwise, the sum of selected Cue channels is heard. MICROPHONE OPERATION Connect the microphone to the appropriate connector. The Main Mic input on the front panel allows the use of a gooseneck mounted microphone. The connector is rotated such that a right angle connector may be used when connecting via mic cable. Use only one of the front or rear Main Mic inputs, both are not operable simultaneously. Leave the Master Level fader in roughly the same position as it was for music. Press in the Mic On switch, lighting the adjacent LED, and adjust the Main Mic (or Aux Mic) Level. The tonal balance of the Main and Aux Mic inputs may be adjusted via the Mic EQ controls. Modifying the sound of the mic in this way won't affect the EQ of the music thru the mixer. When the mic is not in use, release the Mic On switch to its out position to disconnect the mic signal and extinguish the LED. Should the mic preamp become overloaded, the Overload indicator will light. By reducing the appropriate Mic Level control and increasing the Master Level fader, the desired microphone level may be restored without overload distortion. The TAPE OUTPUT does not contain any signal from the microphone section. If you need to record the mics, use the Aux Out for your recording signal; this output is a composite of the Program, Microphone, and Aux input. AUXILIARY IN/OUT The auxiliary input is an insertion point in the mix for added signals. This input combines with the program mix and microphone signal to provide a final mixer output signal. Leave the Master Level fader in roughly the same position as it was for program music. Adjust the Aux In Level control for the desired sound output. The Aux Out provides a final mixer output signal, unaffected by the Master Level fader, for external devices such as tape recorders and video cameras, or for additional zone feeds. [. . . ] THE LAST BEST RIGHT WAY TO DO IT If transformer isolation is not an option, special cable assemblies are a last resort. The key here is to prevent the shield currents from flowing into a unit whose grounding scheme creates ground loops (hum) in the audio path (i. e. , most audio equipment). Do not be tempted to use 3-prong to 2-prong "cheater" adapters to lift grounds. This is a dangerous and illegal practice. [. . . ]
