Connecting a single subwoofer

➊Connecting as LFE channel

XConnect subwoofer to LFE/Slave input.

➋Connecting as subwoofer for satellites

XConnect full bandwidth signal to SAT/SUB input. Sub reproduces sum of right and left signal.

XSet the Mode switch to LFE.

Note:

•You can also use both connection types. The signals will be combined in the BM9S and routed accordingly. This allows the BM9S to reproduce both the LFE channel information as well as the bass range of the connected satellite system.

•Use Slave mode if you want to use an external bass management system.

Multiple subwoofer connections

The BM9S 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.

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 as described before.

2.Set Mode switch of first subwoofer to LFE.

3.From the Slave OUT of the first subwoofer connect a XLR cable to the LFE/Slave IN of the following subwoofer. This one 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:

•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 source subwoofer output, use a Y-connector.
