Here's some stupid suggestions 'cause you've probably already thought of
these, but anyway...
What happens when you try a different Mackie channel?
What happens when you patch the DL-4 into/out-of aux or effect send/returns
instead of using the insert?
What happens when you substitute another unit (non DL-4) for the DL-4? (You
could even use a plain wire.)
I suspect a fault in the mixer since you've changed everything else.

Subject: DL4 problem
Maybe someone has an idea about this...I've had the DL4 running problem-free
for going on two years now. Always connected the same way - Hosa insert
patch cable (1) connected from the L input/L output to the channel 1 (same
channel as my clip-on mic) insert on my Mackie 1202. Recently, I was
getting a tone (registering as a high D# on my tuner) generated thru the
system, which I was able to trace to the DL4. I put in an different Hosa
cable and the sound got slightly louder. I have a performance this Friday,
so I went and bought another DL4, adapter and a Monster patch cable - same
thing, except that now - regardless of which unit or cable - tone generation
seems to be intermittent (?...), but putting an insert in the Mackie jack
'deadens' the mixer - no levels on my effects with it plugged in exactly
where it has always been. Anyone have any idea?
