HX Effects Ext Amp to Tech21 Trademark 60

[Imaginario77]

Hello!

Anyone out there using HX Effects with Tech21 Trademark 60?

I recently got the Hx fx. Wonderful gear. Full of great features.

Used some pods before. Recently Pod Hd500x. But the Helix family seems to take it a step further.

I got the HX Effects to try to make the most of it and its features.

I use the loops, loop 1 to insert some pedals (mainly distortions) and loop 2 to make the 4 Cable Method (4CM). 

I have an expression pedal on input 1 and was trying to control my amp functions with the Ext Amp 2.

 

So far I was able to change channel but I can't access any other functions on my amp. Can't control Boost/Reverb function neither Fx loop on/off. 

The only thing I can think about is that this happens  because my Trademark amp usually uses a standard (mono, Tip/sleeve) cable to connect to its original footswitch and I think the Hx Fx is supposed to use a TRS jack cable. I've tried both with the same result. I can only switch between amp channels.

 

While reading the manual trying to solve this I came across something that worried me because I really don't know what it means: 

"IMPORTANT!  Connect  EXT  AMP  1/2  only  to  amplifiers  that  utilize  "shortto-sleeve"  footswitch  inputs.  Connecting  to  any  other  sort  of  input  could cause  permanent  damage  to  both  your  amp  and  the  HX  Effects  device!  If you're  not  sure  if  your  amp  has  short-to-sleeve  inputs,  contact  the  manufacturer."

 

I don't know what "short-to-sleeve" means... and if this amp applies or not.

Could this be the problem?

Am I in risk of damaging my gear?

Anyone can think of something that might help me?

Thank you so much!

Keep rocking and rolling!
