the area behind it for proper air flow. Otherwise, you could over heat and damage the sub
amplifier.
One more NOTE; because of the acoustics of the sub installed into an enclosed area, we also
suggest using some kind of sound dampening material in the space. This will prevent a hollow
“boomy” sound coming from the area behind the subwoofer.
We all know that one location or setting will NOT work for all installations. Above are only
suggestions. Each installation of these products can be different and you must figure out what
works best for that specific room and system. Make sure to talk with your client and find out
their preference when it comes to bass output and loudness of the subwoofer.
Input Connections of the Subwoofers:
These subwoofers offer several different “input” connections so it should be compatible with
almost all A/V equipment. The “Line Level” input connection is usually the best choice when
connecting the subwoofer to a system that uses a Preamp/Processor and a separate Amplifier or
a Receiver that features main channel preamp output or subwoofer outputs. The “Speaker
Level” inputs are typically used when connecting the subwoofer to a receiver that offers no
subwoofer outputs or preamp outputs.
“Line-in” Line Level input Connections:
To utilize this connect the switch on the back of the subwoofer must be set to “internal x-over”,
this in a non LFE input. Connect a mono subwoofer output on your receiver/pre-amp to the
input connection on the rear panel of your subwoofer. If for some reason you still need more
subwoofer volume, first make sure the volume knob is turn all the way up. Then, if you still
need more volume, attach a “Y” adapter cord to the subwoofer cable and then to both input
jacks. This will give about another 3 to 6dB of subwoofer output.
This connection should be made using a good quality RCA interconnect. Try to keep this cable
as short as possible and also try to avoid running it close to other electrical equipment that
could cause unwanted noise or hum. If the cable is being installed inside the wall cavity, make
sure the subwoofer cable is kept away from electrical wire.
“Speaker in” speaker cable input connections:
To connect your subwoofer parallel with your two main speakers (main R & L) you will use
these connection on the back the subwoofer amp panel. Locate the “Main Speakers”
connections on the back of the receiver. Connect a good quality speaker cable from these
connectors to the “Speaker In” on the back of the subwoofer (the black and red binding posts).
Then also connect a good quality speaker cable from the same connectors on the back of the
receiver to the main Right and Left speakers. Or if the receiver has a “main speaker B”, you can
connect your main speaker to these connectors.
“LFE in” input connection:
If you have and are using a LFE input to this subwoofer, you need to make sure that the switch
on the back of the subwoofer is set to “DIRECT”. This will bypass the crossover and use the LFE
setting from your processor. This input should be connected to a low pass filtered LFE
subwoofer output jack on your receiver/preamp. It is usually featured on the newer 5.1
surround sound receivers, preamps or processors. NOTE: Signals coming into this jack will not
be affected when adjusting the “Low-Pass” level knob on the subwoofer amp panel.
Adjusting subwoofer settings in your receiver/preamp: Read the instruction manual for your
receiver/preamp to understand all settings available for subwoofer, low level, and internal
crossover adjustments. Go to the “Setup Menu” in the receiver or preamp. Find the section for
Subwoofer adjustments and make sure all the proper settings for subwoofer outputs are on and
set to the correct level for that application. Different receivers and preamps will offer different
types of features and setting for subwoofer output.
Digital 5.1 home theater equipment; dedicates one channel to reproduce the special low-
frequency information contained in digitally encoded soundtracks. Go to your receiver’s menu
and select subwoofer “yes”. Having it set this way will relive the amplifier of having to
reproduce the difficult low bass signals that can drive the receiver into audio distortion
.
