I have had my Mod Duo for around two weeks. Having tested it, i found few problems when connected directly to an amp. In the last few days, I have updated some elements (new audio interface and monitor speakers) in order to move form using a physical amp to using Amp simulation. I have added
Focusrite 4i4 Gen 3
Pair of M-Audio BX8 monitors.
If I connect directly to the monitors, all is well. However if i connect via the 4i4, i get substantial interference/noise.
I have ensured my supply is as clean as possible and tried to avoid earth loops. I have tried a laptop as well as my desktop and tried my old audio interface (Line 6 UX2). I am unable to get rid of the noise.
I am also having difficulty setting acceptable gain levels, especially on output. Even at what I consider to be low(ish) settings, I am getting red flashing LEDs on the output stage. At the moment, lowering the input and output gains to get the Mod Duo to ‘behave’ means turning up the input gain on the 4i4 to the point where the interference is intrusive.
I have spent 3 days checking and changing my room layout to try to minimise the impact of this, but it’s still there!
Also, does the Mod Duo go into ‘bypass’ mode when switched off? I touched the end of my guitar cable with the Mod Duo powered off, and still got a buzz throught the 4i4.
Apologies for the long post!
