spikey Posted November 6, 2016 Share Posted November 6, 2016 Are you going to run a guitar cable (from an electric guitar) into that input? Quote Link to comment Share on other sites More sharing options...
d0stenning Posted November 6, 2016 Author Share Posted November 6, 2016 someone on the Facebook group was asking something related to this -because he wants to bring round a friend and plug TWO guitars into his helix. I got curious too. I have guitarist friends round sometimes and wondered about this.The AUX input impedance is lower than normal gtr so only suited according to manual etc - to active pickups - i.e. PU's with low output impedance Quote Link to comment Share on other sites More sharing options...
Ka5par Posted November 7, 2016 Share Posted November 7, 2016 I play into the returns with the Stick. The impedance set to instrument level seems to be lower than what the guitar input is capable of. Don't know the numbers, but it's usable. Quote Link to comment Share on other sites More sharing options...
phil_m Posted November 7, 2016 Share Posted November 7, 2016 I can't find the thread where it's mentioned, but I'm nearly certain that they're 1Mohm. Quote Link to comment Share on other sites More sharing options...
PeterHamm Posted November 7, 2016 Share Posted November 7, 2016 I can't find the thread where it's mentioned, but I'm nearly certain that they're 1Mohm. I doubt that's it, since when you plug a guitar into them it sounds WAY different from the front input set to 1MOhm. I tested it. 1 Quote Link to comment Share on other sites More sharing options...
HonestOpinion Posted November 7, 2016 Share Posted November 7, 2016 These inputs are described in the manual as being intended for 'line level' instruments like keyboards and drum machines so my guess is they have a lower impedance than 1MOhm. Here is a blurb from Wikipedia - "A typical line out connection has an output impedance from 100 to 600 Ω, with lower values being more common in newer equipment. Line inputs present a much higher impedance, typically 10 kΩ (0.01MOhm) or more. Although line inputs have a high impedance compared to that of line outputs, they should not be confused with so-called "Hi-Z" inputs (Z being the symbol for impedance) which have an impedance of 470 kΩ to over 1 MΩ. These "Hi-Z" or "instrument" inputs generally have higher gain than a line input. They are designed to be used with, for example, electric guitar pickups and "direct injection" boxes. Some of these sources can provide only minimal voltage and current and the high impedance input is designed to not load them excessively." I suppose if Line6 is not going to answer the question someone could test their Helix (carefully and in warranty ;) ) with a multimeter.
