AmpPro GM61 and match/helix amplifiers
Looking for some help I setup the Ampro GM61 with 6 channel rca to a match8dsp amplifier. I’m getting audio but volume is relatively low and the ISA in the Helix PCTool is giving input low warning. I have the PAC GM61 at plus 10db and the input gain vrms on amplifier at 2.8(this is lowest it will go). Still get low input gain warning and volume at 80 to 100 percent is medium volume. Has anyone else experienced this what where your amp pro setting also I put switch 2 to on so it’s in 4v mode not 5v anymore.
