User manual M-AUDIO MICROMIXER18

[. . . ] You can then use the knobs to slide the mixer in and out of the rack when you need to change settings. USING A LONGER SCREW WILL CRACK THE CIRCUIT BOARD AND VOID YOUR WARRANTY!If you are rack mounting the unit and need to lock the MicroMixer securely in place (preventing it from sliding forward) you can use the 4/40 machine screws provided to screw through the back of the rack pan and into the MicroMixer itself. Overview While reading the following description of how the MicroMixer works, it may be helpful to refer to the Front & Rear Panels - Figure 1 on the preceding page, or the Block Diagram - Figure 3 located in the back of this manual. Inputs The MicroMixer has 12 inputs with gain control, pan control, two sends per channel and an LED clipping indicator. These inputs provide up to 20dB of gain. [. . . ] Gain controls for the other channels can then be adjusted to achieve the desired mix. Don't be afraid of the yellow Master Level LEDs (+8 dB). For the best results, the yellow LEDs should be lit most of the time. Using the Sends and Returns for the Addition of Effects Inputs 1 through 12 of the MicroMixer each have two effects sends. These sends can be used for several things, the most common of which is to add effects such as reverb or delay to an instrument that has no built-in effects. The MicroMixer also has two effects returns; Mono and Aux. The auxiliary return enables you to incorporate stereo effects in your mix. The mono return is generally used to add an effect to a single source, e. g. If you need more than one stereo return, use two of the regular channel inputs. This technique also enables you to adjust the placement of the effect in the stereo field by adjusting the pan pots on the channels to which you have routed the effects unit. For the best S/N ratio, set the send level on the MicroMixer 6 so that the effects unit is getting the "hottest" possible signal without overloading. Set the effects unit to output wet (processed) signal only and use the MicroMixer's return level to control the mix of processed and non-processed signal. When performing live, you can use one of the sends for an on-stage monitor mix. Processing Microphone Signals Since the MicroMixer has no balanced inputs and is designed to accommodate line level signals, you will need an impedance matching transformer and some sort of mica pre-amp if you want to plug a Low Z microphone into one of the MicroMixer's inputs. If you want to record or process guitars we also suggest that you use a pre-amp rather than run direct. 7 Setting Up Plugging in Line Level Instruments When first setting up, you should decide which instruments you want to be panable and which should run into the unity gain inputs. We recommend that you refer to the "Typical Set-Up - Fig. For the instruments that are connected to inputs 1 through 12, make sure that they are set to their maximum volume, and control the mix level from the channel gain pots. If you see an individual channel's Clipping LED turn on, turn that instrument down slightly. Levels of instruments connected to the unity gain stereo pairs (13 through 18) will have to be controlled from the individual instruments. If you have MIDI volume controllable instruments, much of this level adjustment can be done with your sequencer or MIDI mixing controller. You will also need to decide how to assign effects and sends. If you are using MicroMixer for live performance, you will probably want to use one of the sends as a monitor mix.
