Connections
All connections for the subwoofer are located on the rear of the unit. Whether you choose the LFE (Low
Frequency Effects) coaxial, Left & Right coaxial or XLR-input, the subwoofer is auto selecting the one input
where there is signal.
Multiple subwoofers
When connecting multiple subwoofers, it is recommended to use the XLR pass through to the next subwoofer.
The pass through is a signal split the XLR input. It is also possible to use the RCA signal connections,however
you will need to use “Y” cables (signal splitters) to route your amplifier/receiver/processor output to each
woofer if it does not have multiple “SUBWOOFER” output jacks or L & R variable signal output.
Connections
(Noise issues)
To ensure a safe management of the amplifier and speakers, always only connect and disconnect
signal cables and speaker cables when the amplifier is shut off with the main switch on the back side.
Always use signal and speaker cables as short as possible and of good quality. Long
signal cables of poor quality works as antennas, and might in some cases create noise.
Always connect using the correct phase, from the plus (+) pole on the amplifier to the plus (+) pole on the
loudspeaker and respectively for the minus (-) pole.
Earth ground is often used to reduce noise from electrical interference from outside the casing, however in
some cases several electrical devices which are connected to the same grounding grid can create loops that
pick up interference i.e. ground loops. There are a couple of ways to fix this problem:
• Use the same power strip / power outlet for the interfering equipment.
• Use short as possible signal cables of high quality to minimize resistance and impedance.

In this case, the bass management is performed by the AV Receiver or another external device. We recommend
the following subwoofer settings (please use any of the Line In inputs or the XLR Balanced input.)

Choose a crossover frequency depending on the lower limit frequency of your
speakers.
If you use small speakers, 100-150 Hz is reasonable.
If your speakers are large, use 60-100 Hz.
Set the phase in a way that offers the loudest bass in combination with your other
speakers at your listening position.
Choose a volume level that fits to the other speakers of your system.
