optofonik Posted November 24, 2018 Share Posted November 24, 2018 If someone gains some experience over time and learns in several months (say, 25 months after purchasing) how to recognize the "other unsavory audio artifacts", specific details of which are unfortunately absent in the announcement, what then? It seems that embedding an audio file of the "other unsavory audio artifacts" in the notification posting would have been proper. Quote Link to comment Share on other sites More sharing options...
soundog Posted November 24, 2018 Share Posted November 24, 2018 If you're worried about your HX Effects being a bad boy after you get it, perform this test: 1) Start with a fresh empty patch 2) In block #1 (left upper switch), add a loop block. Keep the default settings. Nothing should be plugged into the loop send/return. 3) In block #2 (middle upper switch), add a Teemah distortion block. Keep it's default settings. Turning the loop block on (and off) should not change the noise level appreciably. If turning the loop on generates a lot of white noise (unusable levels) you most likely have a faulty unit and should open a support ticket with Line 6. 2 Quote Link to comment Share on other sites More sharing options...
codamedia Posted November 24, 2018 Share Posted November 24, 2018 Just to add to Soundog's test.... A faulty unit will have about 12db of added white noise... which is substantial. It sounds like somebody turned a water tap on. A slight increase (1db - 3db) of hiss is normal and expected. 1 Quote Link to comment Share on other sites More sharing options...

Soundog, Codamedia, thank you both for an explanation that can help folks determine if their unit is one of the 1 in 200. I still wonder about the mysterious and vaguely described, "unsavory audio artifacts". I'm a technician so vagaries are anathemas. Quote Link to comment Share on other sites More sharing options...

To put your mind at ease (even just a little)... I don't know of any other "audio artifacts" with the HX Effects other than the white noise with the returns/loops. FYI: I am not commenting on this subject by hearsay, I had one of those units and Line 6 took extremely good care of me. 1 Quote Link to comment Share on other sites More sharing options...

Joe_H Posted November 29, 2018 Share Posted November 29, 2018 I have a question about this test. when setup with loop block in 1 and Teemah in 2 when I engage the loop block it mutes the entire signal. I don't understand the comments about added noise. I assume it's muted because there is nothing plugged into the loop. What am I doing wrong here. Thanks 1 Quote Link to comment Share on other sites More sharing options...

Thanks Nothing needs to be plugged into the INPUT for this test... you don't have to hear your guitar. Simply engaging the loop will add substantial white noise if the unit is faulty. You can also add a RETURN and it will do the same (if faulty). 1 Quote Link to comment Share on other sites More sharing options...
