sub wiring question

Connect the R preamp output to the RCA level input on the R Velodyne.

Connect the L preamp output to the RCA level input on the L Velodyne.

Then use the setup/balance procedures in the Velodynes to integrate them with the main speakers. What this constitutes depends on which version of the SPL subs you have.

Also, this will not roll off the bass in your main speakers. To do this, you might make use of the Tape Monitor loop and the RCA outputs of the Velodynes.

If you have an extra $450 available, I'd grab a Velodyne SMS-1 and run pre
out R and L into the SMS line in R and L with RCAs and then the same scheme
from the SMS line outs into the subs. This will roll off your mains and your
subs. If you have 2 sets of RCA out from your pre, you may wish to run one
set per Kal's set-up and one per mine. This will run your mains full-range.

Either way, IME, you'll be happier.

PS search "SMS" in these forums and you'll see my (never ending -
sorry!) commentary on this excellent product.

Another excellent option is the nht x2 crossover which is much more flexible than the SMS, although it lacks the EQ.

So, which SPL sub do you have? With or without the auto EQ?
