[slinkelist] How can I...

I'm getting really confused now.  I've read so many instances where the
master will allow the slave to come through when the master is in pause
mode.  And yet I've read responses where the master does not.  Mine will not
allow the slave to come through when it's in pause mode.  I'm wondering if
the different Megacontrol units behaves differently?

Some interesting discussion -- but I disagree with a couple of the comments
listed.....

Master/Slave WILL work with CDJ -- MegaControl will not.  To get CDJ to work
with Master/Slave, connect the Slinke to the Master, connect the slave to
the master using a S-link cable (make sure you set the slave to 3 rather
than 2), connect the audio out of the slave to the audio in on the master,
connect the audio out on the master to your receiver.

In this scenario, cross fade from CDJ will not work properly.  BUT, audio
from the slave will pass through the master when the master is in
pause.......do not connect the Slinke to both changers, as CDJ will pick
this up as four players rather than two.

To achieve cross fade with CDJ, you must make a passive mixer (as alluded to
in prev posting).  I was using the configuration mentioned above when I
first set up my Slinke/CDJ controls.  I later made a trip to the Shack
(Radio Shack, that is) and made a passive mixer -- quite simple and only
about six bucks.......
