Using the Full-Range Low-Level Input for Driving the Built-
In Powered Subwoofer
Your C/L/R 2500(s) has a separate RCA input jack labeled “Full Range
Low Level In” which may be used to drive the built-in powered subwoofer
directly from your preamp or preamp section of your receiver (if you have
center channel low-level full-range output).
This input should be connect-
ed to a full-range center channel output from your pre-amp or decoder
and not from “Subwoofer or LFE Out.”
Many experts feel that this
method of hook-up results in the clearest, tightest and deepest bass.
If you do not have two sets of center channel low-level full-range out-
puts, use a
Y connector coming out of the center channel pre-out of your
receiver or amp with one half of the Y going to the main center in of your
receiver or amp and the other half going to the low-level input on your
C/L/R 2500. Please note that not all receivers have a low-level full-range
center channel output, so you may not be able to use this hook-up method
with your particular piece of electronics.
