Connecting a single subwoofer

➊Connecting the SAT/SUB input

XFrom the preamplifier output of your processor/receiver (often marked as Pre Out or Front Out) connect a stereo RCA cable to the subwoofer SAT/SUB Input.

This signal should not be already processed by the processor/receiver. Please pay attention to the settings of your processor/receiver.

➋Connecting the LFE channel

XFrom 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 cable to the subwoofer input SUB I/O - LFE/Slave In.

This signal should not be already processed by the processor/receiver. Please pay attention to the settings of your processor/receiver.

XSet the MODE switch to LFE.

Note:

•You also can use both connection types. Both signals will be combined in the

SUB 250 and routed accordingly. This allows the SUB 250 to reproduce both the LFE channel information as well as the bass range of the connected satellite speakers.

Multiple subwoofer connections

The Dynaudio SUB 250 can be used stand-alone or together with multiple subwoofer units. Using multiple units may be helpful if the listening room is quite large or has difficult acoustic conditions (e.g. room-modes, see also “Positioning the subwoofer” on page 12 for further information).

When using two or more subwoofers, the first one (designated “Master”) controls the following subs (designated “Slave“) via a subwoofer cable.

Connecting multiple subwoofers

1.Connect the first subwoofer with the processors/receiver as described before.

2.Set MODE switch of first subwoofer to LFE.

3.From the SUB I/O - LFE/To Slave output of the first subwoofer connect a mono RCA-to-RCA cable to the SUB I/O - LFE/Slave In input of the following subwoofer. This now becomes the slave.

4.Set the MODE switch of the second subwoofer to Slave.

XFurther subwoofers can be connected in the same way. Set the MODE switch of all following subwoofers to Slave respectively.

Note:

•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.
