Is a 140 suitable for ATC SCM 7 v1? I powered the SCM 7 v3 with a 140 in the past no problem. I’ve never heard the v1 before, and I seem to remember that older ATCs needed more grunt. Not sure if that applies to the v1.
Hi, yes the earlier ATCs (rectangular box) do require a stiffer amp/ more grunt… I suspect down to a more varying impedance curve combined with relatively low sensitivity.
