CONTROL APPLICATION 4.2 Application on Single Instrument If you wish to use your LTO Q as an "in line" processor and use it for single instrument equalization, you must connect the output of the instrument to the input of your LTO Q and the output of the LTO Q to the input of an amplifier.

However, we advise you to read carefully the following section to be the real master of your own mix. Not paying attention enough to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow this procedure for every single channel: 5.
