Maestro77 Posted December 22, 2018 Share Posted December 22, 2018 hey, can i use the guitar input with a dynamic mic on helix lt? there are cables that would open up this opportunity. will this result in worse quality compared with the xlr input on normal helix (non LT) ? or are these inputs basically identical aside from the xlr/line jack? or are there some kind of impedancy differences or does the normal helix have some integrated mic preamp that boosts the signal? would really be interesting to know more about this subject. thank you very much!

zolko60 Posted December 22, 2018 Share Posted December 22, 2018 You can try, nothing dangerous should not happen. Mikes have very low voltage on low impedance, using unbalanced input you lose 6dB. The signal after AD conversion will be very low. This is why mic preamps were invented. Set guitar input to the lowest possible impedance, use one or two boosters - maybe you can push it to usable level. BTW - You can also try passive transformer Di box reversed.

tfysh Posted December 25, 2018 Share Posted December 25, 2018 I use an impedance matching transformer (see link) to run my vocal mic into an HXFX return (set to "Instrument"). Works great! https://we-supply.com/impedance-transformer-xlr-3-pin-female-to-1-4-ts-mit-176 1 Quote Link to comment Share on other sites More sharing options...
Maestro77 Posted December 25, 2018 Author Share Posted December 25, 2018 thank you guys! the impedance matching transformer sounds like a nice solution. :) Quote Link to comment Share on other sites More sharing options...
