VS-2480, VS-2400: Using an external loop effect on the VS-2400 / 2480
There are 2 ways in which an effect is applied to a signal. Depending on what you want to accomplish with the effect, you will either INSERT the effect or LOOP it.
Inserting an effect means that you want the signal to be completely changed by the effect, all you want to hear is effected signal. Typically the Effects you would use in such a way would be EQ, Compressors, Hum Cancelers, Noise Supressors, Pitch Correction, Mic and Amp Simulation, etc.
Looping an effect is best suited for effects that accentuate existing signal. A looped effect will produce a sound that contains a balance between "dry" and "effected" signal, which can be adjusted to suit your needs. Effects in this category are, Reverb, Delay, Chorus, Phase, etc.
To use an external effect unit, we will take advantage of the VS-2400 / 2480 Aux Bus.
Step 1.) Press EZ-ROUTING.
Step 2.) Push F4 to get to the OUTPUT ASSIGN section.
Step 3.) Use your mouse or the Cursor Keys to select AUX A from along the top, and turn the TIME/VALUE Wheel to assign this output to an available aux (usually 7/8 is a good choice).
Step 4.) Push the CH EDIT (Channel Edit) button for the channel you wish to be affected.
Step 5.) Cursor down to Aux 7/8, turn ON the AUX SW, and raise the level up to 0db.
(Repeat this process for any other channels you want to be affected in this way by the external processor.)
Step 6.) Connect the AUX A outputs (1/4" outputs 3&4) to the Left and Right inputs on your processor.
Step 7.) Connect the Left & Right outputs of the Processor to a pair of inputs on the VS-2400 / 2480. (These inputs need to be routed to empty channels. If they are not already, you will need to route them so.) These are now your FX returns, and you will hear the effected signal here.
