How to connect effect devices and signal processors
Alesis and other companies make many different types of signal processors which may be connected to the Multimix 12R mixer. There are two ways to connect these units: using the AUX system or via the INSERT jacks.
Effects via Aux Send and Aux Return
If you want to add an effect such as reverb, chorus, or delay to several different inputs at once, you will use the AUX system.
1.Connect the AUX 2 (POST) AUX SEND output of the 12R to the input of the effect device. If the effect has a stereo input, check the manual of the effect to see which jack is the mono jack. (In most cases, you won't need to connect anything to the other input jack of the device, but you will still get a stereo effect output).
2.Connect the left and right outputs of the effect device to the [STEREO AUX RETURN] jacks of the Multimix 12R.
•Alternatively, you may connect the output of the effect device to either of the STEREO LINE channels
About stereo effect devices
✪If your effect unit has two inputs, in most cases you need to connect from only ONE Aux Send to the left (mono) input of the effect unit, but you will still connect both the left and right outputs of the effect to the STEREO AUX RETURN.
