SETTING UP & TUNING IN
Master and Slave mode
The subwoofer can operate in two different modes: Master
or Slave mode. If your system consists of multiple
subwoofers, it is desirable that all subwoofers operate with
identical settings (Volume, Low-Pass filter (Hz), Phase and
LF Extension).
Using the Master/Slave feature of Dynaudio subwoofers
this is easily achieved: The Master subwoofer (connected
directly to the subwoofer Output of the amplifier or receiver)
will control all Slave subwoofers (connected to the Master
subwoofer). Thus, using a single remote control, all
subwoofers in the system will follow all settings from the
Master subwoofer. Note that in Slave mode, only the
On/Off and Auto/Manual selections are available.
Single subwoofer connection
From the processor or receiver's low-level (not a speaker
Output) subwoofer Output (often marked as "subwoofer
out", "Sub out" or "LFE"), connect a mono RCA-to-RCA
(No. 4 in fig. 2; refer also to fig. 3) or XLR-to-XLR patch
cord to the subwoofers Input. Refer also to the section
"Using the XLR connectors" below in this chapter.
Set the subwoofers Input switch (No. 7 in fig. 2) to the
"Master" position if you wish to use and change the
settings with the remote control.
After all connections are made, connect the supplied
mains lead to the subwoofers IEC power socket (No. 1 in
fig. 2) and a mains outlet.
Multiple Subwoofer connection
From the processor or receiver's subwoofer Output (often
marked as "subwoofer out", "Sub out" or "LFE"), connect
a mono RCA-to-RCA or XLR-to-XLR patch cord to the
Input (No. 4 in fig. 2) of the first subwoofer in the daisy-
chain. This is now the Master subwoofer.
Set the master subwoofers Input switch (No. 7 in fig. 2)
to the "Master" position.
From the Master subwoofers "processed Out" Output
(No. 6 in fig. 2), connect a mono RCA-to-RCA or XLR-to-
XLR patch cord to the next subwoofers (Slave) Input.
Refer also to fig. 4.
Any subsequent Slave subwoofers can be connected in
a daisy-chain style, going from the "processed Out"
Output (No. 6 in fig. 2 to the next Slave subwoofers
Input.
Set the Slave subwoofers Input switch (No. 7 in fig. 2) to
the "Slave" position.
After all connections are made, connect the supplied
mains leads to the subwoofers IEC power sockets (No. 1
in fig. 2) and a mains outlet.

In order to avoid interference and noise, we
recommend you use quality, well shielded cables.
When using multiple subwoofers in a Master-
Slave setup, it is recommended that the
subwoofers are all the same model.
If you wish to use multiple subwoofers with full
individual control, set the Input switch for all to the
"Master" position. From the Amplifier, processor or
receiver's subwoofer Output, use a Y-connector.
