Connecting Your Subwoofer - Audio Physic Luna Owner's Manual

Connecting Your Subwoofer

Please switch off 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 different possibilities when it comes to connecting your subwoofer to your system.
Operating Your Subwoofer in a Stereo Configuration
You can integrate your subwoofer into your stereo music system in a variety of ways. If you have a com-
bination consisting of a preamplifier and a power amplifier with a free „pre-out" on the preamplifier,
you can use this to connect your subwoofer. This also applies to integrated amplifiers 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) Connecting your subwoofer with an RCA cable:
LUNA connection terminal
2) Connecting your subwoofer with a loudspeaker cable:
You can also control your LUNA by using a second loudspeaker output on your amplifier. To do so, you
need to connect the loudspeaker outputs, normally marked as "B", of your integrated or power amplifier
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 connection method can be used without
any problems. Connect the cable from the left loudspeaker with the left "high level input" of your LUNA
and connect the right channel with the right input accordingly.
Connection with a
loudspeaker cable:
Use the high level
input to connect your
subwoofer to the right
and left loudspeaker
outputs of your
amplifier or
loudspeakers.
If you hear a clear humming noise once you have activated your subwoofer after connecting it using this
method, it is very likely that this is due to a difference in the ground potentials. You can find out how to
simply rectify this problem on the following page.
