CM-64 reboots

[reines]

Hi,

I wanted to ask if its normal for CM-line devices to reboot on imperfect headphone/line-out contacts. For a CM-64 exhibiting this problem, I solved it by resoldering the jacks, but still I wanted to know if the reboot on imperfect connections behavior is normal for the CM line.

Thanks

While I've never had a reboot, I find the CM line's RCA jacks quite error-prone. On my CM-500, the volume of the right channel seems to vary depending on how much pull there is on the cable, which is not the case for the left channel or both of the CM-64's jacks.

Modifying for XLR connectors and impedance-balanced outputs might be a fun project though.

Intermittent contacts generate noise spikes which in turn crash/reset the CPU? wouldn't surprise me.

Haven't seen problems with solder joints on Roland gear, but plenty of other equipment from the 80's suffers from it
