Connecng Your Subwoofer
Please switch o all equipment in your HiFi system before you connect your subwoofer. Depending on
how you want to use your subwoofer, for example in a stereo or surround sound system, there are a
number of dierent possibilies when it comes to connecng your subwoofer to your system.
Operang Your Subwoofer in a Stereo Conguraon
You can integrate your subwoofer into your stereo music system in a variety of ways. If you have a com-
binaon consisng of a preamplier and a power amplier with a free „pre-out“ on the preamplier,
you can use this to connect your subwoofer. This also applies to integrated ampliers or receivers that
have an unused pre-out connector. Use an RCA cable of a suitable length to connect the “pre-out” jacks
to the LUNA’s “low level input”. “Record-out jacks” are not suitable for this purpose.
AUDIO PHYSIC recommends that you use the “high level input” to connect your subwoofer.
1) Connecng your subwoofer with an RCA cable:
2) Connecng your subwoofer with a loudspeaker cable:
You can also control your LUNA by using a second loudspeaker output on your amplier. To do so, you
need to connect the loudspeaker outputs, normally marked as “B”, of your integrated or power amplier
with the loudspeaker terminals on your subwoofer. Depending on the setup of your system, you can also
connect your subwoofer with cables from the loudspeakers in order to save cable. Loudspeakers mostly
accept cables with spades and banana plugs, meaning that this connecon method can be used without
any problems. Connect the cable from the le loudspeaker with the le “high level input“ of your LUNA
and connect the right channel with the right input accordingly.
If you hear a clear humming noise once you have acvated your subwoofer aer connecng it using this
method, it is very likely that this is due to a dierence in the ground potenals. You can nd out how to
simply recfy this problem on the following page.
