effect loop level

[kreator1972]

on my Blackstar Ht-5R amp I have the option to switch the effect loop to -10dbmv or +4dbmv

 

wich level should I use for the 4 cable method ?

 

anyone got experience with this amp model with the Helix ?

Use -10dBv for any amp.

 

it is a lower level and closer to the instrument level that you need to send from Helix's SEND socket to the HT5 amp front input.

 

+4dB might cause clipping, because you need to set the Helix's Send/Return to instrument level (in Global settings) or otherwise if you choose LINE you'll be putting way too much signal into the front to the HT5 - which is expecting to see a guitar signal powered by the swipe of a plectrum.

 

If you choose +4dbU on the HT5 then the signal coming back into the Helix's RETURN socket from the HT5 amp's SEND will be a LOT louder than what you are sending into the front of the amp.   I already find I need to turn down the RETURN level on the Send/Return block to about -15dB when I use -10dBv to maintain a similar level to when the Send/Return block is bypassed.  If you used +4dbU you'd probably need to turn it down 25 or 30dB.
