DL4 problem

[Tom Heasley <heasley@hypnos.com>]

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?
