DL4 et la boucle d'effet ?

Citation : Q: Can I run my Line 6 Modeling pedal in a parallel or series effect loop?
A: Line 6 does not support the use of any Line 6 Four Button modeling pedal in an effect loop, as the Line 6 Modeling pedals are designed for instrument level (guitar/bass output) to be inserted between the instrument and the amplifier. The signal strength of a line level signal (i.e. an effect loop) can cause the input buffers to fail.

Citation : Q: What if I have a level control on my effect loop?
A: It is up to the player to determine how to set the effect loop level according to personal taste, but Line 6 does not recommend placing any Line 6 Four Button modeling pedal in an effect loop. The send would need to be reduced to approximate a guitar level signal (i.e., -22db, 1.5v pp max, etc). The problem with this is that you rely on the modeling pedal for make up gain, which if you tailored the input would result in higher noise floor. If a loop is the only desirable way to connect a Line 6 Modeling pedal, you will need a -22db pad on the front end and a +20db buffer on the output to make up the gain.

Citation : If you are using the Guitar > Chromatic Tuner > DL4 > Amp head configuration, the DL4 will only affect the dry signal of the guitar and send that to the front of the head. So, if you are using the distortion on the ENGL, the delay repeats from the DL4 will also be distorted.

It would be best to use the DL4 within the effects loop of your amp, but you would just have to make sure that the 'Effects Send' signal going into the DL4's input is at instrument level and that you have a +20db buffer after the output of the DL4 so that you can have enough volume going back into the 'Effects Return' on your amp as the knowledge base document says.
