PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
Power supply/Power cord
· Only use the voltage specified as correct for the device. · Use only the specified AC power adaptor (PA-20 or an equivalent recommended by Yamaha). · Do not place the power cord near heat sources such as heaters or radiators, and do not excessively bend or otherwise damage the cord, place heavy objects on it, or place it in a position where anyone could walk on, trip over, or roll anything over it.
Water warning
· Do not expose the device to rain, use it near water or in damp or wet conditions, or place containers on it containing liquids which might spill into any openings. [. . . ] The send signal is fed to the monitor power amplifier and speaker system. The channel fader does not affect the send level so the monitor mix remains independent of the main mix. No return signal is used in this case.
Channel Fader AUX Send Level

AUX Send Level
AUX Return Level
Post-fader send for external effects processing. The send signal is fed to the external effect unit--a reverb unit, for example--and the output from the effect unit is returned to the AUX Return jack and mixed back into the main program. The send level is affected by the channel fader so the effect level always remains in proportion to the channel signal.

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. Simply assign the group to a group bus, and make sure that group is also assigned to the main program bus. Then you can adjust the overall level of the group using a single group fader, rather than having to attempt to control multiple channels faders simultaneously. Group buses usually also have their own outputs, so you can send the group signal to a different external destination from the main mix.
Channel faders Assigned to Group (Controlled As a Group)
A group of channels whose levels need to maintain the same relationship--a drum mix, for example--can be assigned to a group bus. Usually the group bus signal can be output independently via "Group" outputs, or it can be assigned to the main program (stereo) bus to be mixed in with the main stereo program.
Group Fader
Once the mix between the channels assigned to the group is established via the channel faders, the overall level of the entire group can be conveniently adjusted via a single group fader.

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. Channel inserts are most commonly used for applying a dynamics processor such as a compressor or limiter to a specific channel--although they can be used with just about any type of in/out processor.
Channel Fader
When a plug is inserted into the channel insert jack, the internal signal path is interrupted and sent outside the mixer for external processing.
Channel insert jacks must be used with a special insert cable that has a TRS phone jack on one end and mono phone jacks on the split "Y" end. One of the mono phone jacks carries the "send" signal to be fed to the input of the external processor, and the other carries the "return" signal from the output of the processor.

5. Well, you can do it that way, but a more systematic approach that is suited to the material you're mixing will produce much better results, and faster. There are no rules, and you'll probably end up developing a system that works best for you. Here are a few ideas to get you started:
Music First--Then Mix
In any case, the music comes first. Think about the music and let it guide the mix, rather than trying to do things the other way around. What is the music saying and what instrument or technique is being used to drive the message?You're using a high-tech tool to do the mixing, but the mix itself is as much art as the music.
