12THE OUTLAW’S GUIDE TO THE SMS-1
What if you have a receiver that lacks a subwoofer output and you don’t
have an outboard amp, mains-in jumpers, an external processor loop, or
even pre-amp outputs? Well, the SMS-1 does have left/right speaker level
inputs. To use these, connect an extra pair of speaker cables to the left
and right channel binding posts. Connect the other end of these cables
to the SMS-1’s speaker level inputs. The SMS-1 will use these signals and
the low-pass crossover (see page 18) to generate a subwoofer signal.
Once again, the mains will still be getting a full range signal.
Between the line inputs (unbalanced and balanced) and the speaker
inputs, you should now have some sort of signal hooked into the SMS-1.
Now we’ll move onto some outputs.
OUTPUT
The most obvious output need we have is a subwoofer connection. Near
the middle of the rear panel is a group of three black output jacks labeled
“LFE Outputs.” You can connect up to three subwoofers to these outputs.
Since all three carry an identical signal, it doesn’t matter which you use.
If your subwoofer has a balanced input, you might want to use the bal-
anced LFE output located at the far left end of the rear panel. As we men
-
tioned earlier, the balanced and unbalanced signal paths are shared so
that balanced inputs are available at unbalanced outputs and vice versa.
In general, however, we recommend sticking with the same connection
type through the entire signal path.
There is one other output that you simply must have hooked up to use
the SMS-1: the EQ output. This output carries the SMS-1’s test tones to
your receiver or processor. We recommend picking a spare video input
on your receiver and leaving the SMS-1 connected, but if you are running
short on open inputs you can use a front input and only connect it when
you need to make adjustments (which should be very rare once you
get the unit dialed in). The “EQ Output” is an analog stereo output that
will connect to whatever input you select on your receiver. The “Video
Output” (either composite or s-video) needs to be connected to the same
input on your receiver to give you access to the on-screen menus. We
want this input on your receiver to be set to stereo (no surround process-
ing required), and we do not want to use analog bypass (which would
defeat the receiver’s bass management).
The LFE output and EQ output are the essentials, but there are still some
outputs that we haven’t talked about yet. A short while ago we talked
about connecting the left and right pre-amp outputs of your receiver to
the “Input” jacks on the SMS-1, but we didn’t tell you what to do to get
those pre-amp signals on to your amps (or back to your receiver if you are
using an external processor loop). That’s where the “Output” jacks come
in. This stereo analog output contains an 80Hz high-pass crossover, so
that the left and right speakers don’t have to handle the low frequency
material that the subwoofer will be taking care of. If you connected your
receiver or processor’s pre-amp outputs to the “Input” of the SMS-1, you
will want to connect the SMS-1’s “Output” to your amp.
There’s one set of connections with the somewhat curious label “Thru”
that we haven’t mentioned yet. The “Thru” output is a direct copy of the
“Input” signal, without any processing or bass management applied. If
