- Page 2 • If this device or the AC power adaptor should be dropped or damaged, immediately turn off the power switch, disconnect the electric plug from the outlet, and have the device inspected by qualified Yamaha service personnel. Connections • Before connecting the device to other devices, turn off the power for all devices.
- Page 3 Even when the power switch is in the “STANDBY” position, electricity is still flowing to the device at the minimum level. When you are not using the device for a long time, make sure you unplug the power cord from the wall AC outlet. The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualifi ed Yamaha service personnel about replacing defective components.

Introduction Introduction Thank you for your purchase of the YAMAHA MG12/4FX mixing console. The MG12/4FX features input channels suitable for a wide range of usage environments, and includes high-quality built-in digital effects that can provide some very serious sound. The mixer combines ease of operation with support for multiple usage environments. -
Page 5: Before Turning On The Mixer
Before Turning on the Mixer Be sure that the mixer’s power switch is in the STANDBY position. Use only the PA-20 adaptor included with this mixer. Use of a different adaptor may result in equipment damage, overheating, or fire. Connect the power adaptor to the AC ADAPTOR IN connector ( 1 ) on the rear of the mixer, and then turn the fastening ring clockwise ( 2 ) to secure the connec- tion. -

Making the Most Of Your Mixer Making the Most Of Your Mixer ■ An Introduction You’ve got yourself a mixer and now you’re ready to use it. Just plug everything in, twiddle the controls, and away you go … right? Well, if you’ve done this before you won’t have any problems, but if this is the first time you’ve ever used a mixer you might want to read through this lit- tle tutorial and pick up a few basics that will help you get better performance... -
Page 7: How Do Balanced Lines Reject Noise
■ The Sturdy XLR This type of connector is generally referred to as “XLR-type,” and almost always carries a balanced signal. If the corresponding circuitry is designed properly, however, XLR-type connectors will also handle unbalanced signals with no problem. Microphone cables usually have this type of connector, as do the inputs and outputs of most Male professional audio gear. -

+4 dB. Be sure to set these switches to match the level of the connected equipment. ● Inputs that feature a “Gain” control—such as the mono-channel inputs on your Yamaha mixer—will accept a very wide range of input levels because the control can be used to match the input’s sensitivity to the signal. More on this later. -
Page 9: Where Your Signal Goes Once It's Inside The Box
2. Where Your Signal Goes Once It’s Inside the Box At first glance the block diagram of even a modest mixer can look like a space-station schematic. In reality, block diagrams are a great aid in understanding how the signal flows in any mixer. Here’s a greatly simplified block diagram of a generic mixer to help you become familiar with the way these things work. -

Making the Most Of Your Mixer 3. The First Steps in Achieving Great Sound Before you even consider EQ and effects, or even the overall mix, it is important to make sure that levels are properly set for each individual source. This can’t be stressed enough—initial level setup is vitally important for achieving optimum perfor- mance from your mixer! Here’s why …... - Page 11 3-2. Level Setup Procedure For Optimum Performance Now that we know what we have to do, how do we do it? If you take another quick look at the mixer block diagram you’ll notice that there’s a peak indicator located right after the head amplifier and EQ stages, and therein lays our answer! Although the exact procedure you use will depend on the type of mixer you use and the application, as well as your personal preferences, here’s a general outline: Start by setting all level controls to their minimum: master faders, group faders (if provided), channel faders, and input...

Making the Most Of Your Mixer 4. External Effects, Monitor Mixes, and Groups 4-1. AUX Buses For Monitor Sends and Overall Effects There are a number of reasons why you might want to “tap” the signal flowing through your mixer at some point before the main outputs: the two most common being 1) to create a monitor mix that is separate from the main mix, and 2) to process the signal via an external effect unit and then bring it... -
Page 13: Using Groups
4-2. Using Groups Group buses and faders can greatly simplify the mixing process—particularly in live situations in which changes have to be made as quickly as possible. If you have a group of channels that need to be adjusted all together while maintaining their relative levels, grouping is the way to go. -
Page 14: Channel Inserts For Channel-Specific Processing
Making the Most Of Your Mixer 4-3. Channel Inserts for Channel-specific Processing Another way to get the mixer’s signal outside the box is to use the channel inserts. The channel inserts are almost always located before the channel fader and, when used, actually “break” the mixer’s internal signal path. Unlike the AUX sends and returns, the channel insert only applies to the corresponding channel. -

5. Making Better Mixes 5-1. Approaching the Mix—Where Do You Start? Mixing is easy, right? Just move the faders around until it sounds right? Well, you can do it that way, but a more sys- tematic approach that is suited to the material you’re mixing will produce much better results, and faster. - Page 16 Making the Most Of Your Mixer ■ Spread them Out! Position your instruments so they have room to “breathe,” and connect in the most musical way with other instruments. Sometimes, however, you’ll want to deliberately pan sounds close together, or even right on top of one another, to empha- size their relationship.

Channels 9/10 and 11/12 To get the best balance between the S/N ratio and the (Stereo) dynamic range, adjust the level so that the PEAK indica- tor (2) comes on only at about maximum input level. - Page 18 Front & Rear Panels PRE Switch Selects whether the pre-fader or the post-fader signal is fed to the AUX bus. If you set the switch on ( mixer sends the pre-fader signal (the signal prior to pas- sage through channel fader B) to the AUX bus, so that AUX output is not affected by the fader.
