jaybee77 Posted July 19, 2017 Share Posted July 19, 2017 Hello. Im loving the Helix and wanting to link up my Boss RC-300 looper to the helix. Im going from the Helix 1/4" outs - into the L/R inputs on the RC300 - and then out to the stereo return on my Yamaha THR100HD What should i set the Helix 1/4" outputs to - Instrument or Line ? Info in the RC-300 manual is as follows.... INPUT Nominal Input Level INPUT INST: -10 dBu (variable) Input Impedance INPUT INST: 1 M ohm OUTPUT Nominal Output Level MAIN OUTPUT: -10 dBu Output Impedance 2 k ohms Recommended Load Impedance 10 k ohms or greater.... I could also use a Helix F/X loop to connect to the RC300... thanks for your help Quote Link to comment Share on other sites More sharing options...
Joepeggio Posted July 19, 2017 Share Posted July 19, 2017 With the 10m input impedance, any either one should work. You said variable, so I believe you can set unity gain that way. If it can handle it, line would provide better signal to noise ratio. I would contend that getting to line level sooner in a signal chain will have less noise issues if any Quote Link to comment Share on other sites More sharing options...

I have just got home and set it all up. With the 10m input impedance, any either one should work... - Did you mean 1 M ohm? It is a 1 M ohm input impedance ! Tried both Instrument and Line. Line seems to have more noise/hiss than instrument - But im guessing that's due to instrument signal being lower in level so the Line seems to amplify more noise? Yes i can set unity gain via the input 'Variable' level knob... Will try the send return method... but then have to add an F/X block to every patch that i have made and the factory presets where as using the main 1/4" outs is straight forward - no editing of patches required...
