4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
About this manual This manual is divided into three main chapters. ▪ Before you start: Learn how to unpack and connect the subwoofer. The controls and connections on the back panel are also described here. ▪ Operation: In this chapter you will learn how to operate the subwoofer and how to position it properly for optimum performance.
Before you start Unpacking the subwoofer ▪ Unpack the subwoofer on a clean, flat and soft surface; floor carpeting is suitable. ▪ The packaging should be opened from the top (1). Remove all accessories packed with the subwoofer (such as the AC power cord).

Gain Phase Slave SAT/SUB The 9S provides two different signal inputs: LFE/Slave This input allows the LFE (Low Frequency Effect) channel to be connected. The signal is: ▪ reproduced by the subwoofer ▪ routed to the Slave output for a second subwoofer to be connected.
▪ Connect the full bandwidth signal to the SAT/SUB input. The subwoofer reproduces the sum of right and left signals. ▪ Set the Mode switch to LFE. Notes ▪ Both connection types can be used simultaneously. The signals will be combined in the 9S and routed accordingly. This Before you start...

If either subwoofer or main speaker are slightly out of phase in relation to the other, it can result in decreased bass output in the frequency response area where they overlap each other.

Freq. ▪ Red: Combined frequency response ▪ Grey: Subwoofer ▪ Black: Main speakers The phase relationship between subwoofer and satellite speakers is dependent on their relative distance to the listening position and on the working principles of the satellite speakers. The figure above shows a case in which the phase of the subwoofer and satellite speakers is incorrect in the critical overlap area, thus reducing acoustic output in the listening room in that region.

It is useful therefore to limit the bass range of the connected speakers (called “satellites” in this case) through a high-pass filter. The 9S provides two high-pass filter settings to achieve this: ▪...
Troubleshooting There may be various reasons why a subwoofer doesn’t function properly in a system without it being faulty. The checklist below will help solve any problems you may encounter. Before consulting your Dynaudio Professional dealer, check this list first.
Page 21
Cause ▪ No signal is present on either of the subwoofer inputs. ▪ The subwoofer output in the source bass-management has been disabled. ▪ Source subwoofer volume level is at zero. ▪ Subwoofer volume level is at zero. Solution Make sure to switch off the system before making any changes! ▪...
DANGER Dangerous voltage inside! Cleaning the 9S or other system components when switched on can lead to damages or electric shock. Switch off the subwoofer and all other components of your system when cleaning. To clean the subwoofer: The cabinet and other plain parts should be cleaned with a soft dry or slightly damp cloth.
