Hi all,
I recently got a Micro Lynx unit and built cables per the attached document (using screened twisted pair cable) for linking up my two Otari MX70 decks.
Everything is working well except for a faint but very annoying 9.6kHz tone bleed into my monitor amp (an old McIntosh MC 2120) whenever the capstan is set to 'resolved' (it immediately disappears when the capstan is set to 'wild'). I experimented with putting a 1:1 edcor transformer in the patch bay between the amp and my console and it reduces the tone pretty considerably (-10db or so) but it's still there. The level of the tone is not affected by the monitor volume on my console.
Just wondering if anyone else has encountered this? I bought another system unit for spare parts and I noticed the owner insulated one of the boards from the chassis with duct tape. Maybe grounding issues are common with these?
Thanks in advance for any clues.
