Unpacking & Installation Lift out the subwoofer unit from the packaging, care must be taken not to depress the drive unit cones as this could result in permanent damage. Fix the four feet to the underside with the screws provided. The subwoofer unit should be positioned in the most suitable position, preferably not in the corner of a room as this may cause a pronounced boom. It is important to position the subwoofer initially to have easy access to the control panel.
Monitor Subwoofers Safety Instructions 1 Read Instruction All the safety and operating instructions in this Manual should be read before the appliance is operated. 2 Retain Instructions Retain this Owners Manual for future reference. 3 Note Warnings All warnings on the appliance should be adhered to.
10 Power Cord Protection Power supply cords should be routed so that they are not likely to be stepped on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles and the point where the cable exits the appliance. 11 Non Use Periods The power cord of the appliance should be unplugged from the mains outlet when left unused for a long period of time.
Mains Connection Important Check the voltage setting. Do not connect the appliance to an incorrect power supply, as serious damage may occur. Do not connect the power supply until all other connections have been made. Position/Location Your Monitor Audio Subwoofer should perform well in just about any room location. In fact unless your ear is within a couple of feet of the subwoofer, the bass should seem to radiate from your main speakers.

Subwoofer connections There are a number of ways to connect your subwoofer into your system. One uses loudspeaker cables, the other uses interconnect cables with RCA phono plugs. Looking at the rear panel of your subwoofer you will see two sets of speaker terminals, one labelled ‘high level input’, the other ‘high level output’, and RCA phono socket labelled ‘input’ (left and right). The configuration of your system will determine how you will connect your subwoofer. 1.
6. RCA Phono Output (FB210 only): This facility can be used to link out to an additional power amplifier. The RCA phono output can also be used to daisy chain a number of sub woofer units together. 7. RCA Phono Input Connection: This method of connection is recommended for optimum performance. Input should be provided at line or signal level from a pre-amplifier or A.V. receiver.
Standard amplifier - speaker cable connection This method will involve connecting your subwoofer to the amplifier using loudspeaker cables. To do this you make the same kind of connections that you would use for your main / satellite speakers, except both your left and right channels go to the subwoofer. 1 Connect the amplifiers left channel Red (+) to the subwoofer left channel Red (+) ‘high level input’ terminals.
Satellite speaker wiring option 1 With this option, you connect the wiring for the main/satellite speakers directly to the subwoofer. There is no performance advantage in wiring your system this way, it may just be a factor of convenience, remembering to keep the speaker cables approximately the same length to avoid different loading to the amplifier. 1 Connect the subwoofer Red (+) ‘high level output’ terminal to the Red (+) terminal on the back of the left main / satellite speaker.
Speaker-level high pass filter Monitor Audio’s subwoofers have a high pass filter. When your main/satellite speakers are connected to the ‘speaker output’ terminals on the subwoofer, the low bass frequencies below 100Hz are filtered from your main / satellite speakers. This filter significantly reduces the bass demands placed on your main / satellite speakers and can make a considerable improvement in their sound quality, especially in the mid-bass and lower midrange.
Main/Satellite speaker wiring option 2 This option has the main/satellite speakers directly connected to the amplifier. This requires 2 sets of speaker cables, one set running to the main / satellite speakers and the other running to the subwoofer. If your amplifier has only one set of speaker terminals you can connect the main / satellite speakers to your amplifier using the same high level output terminals as the subwoofer. Do not connect the main / satellite speakers to the subwoofer. Fig.
Wiring with a pre amplifier and separate power amplifier The ‘pre-amplifier’ RCA input phono sockets on the subwoofer, allows you to directly connect the subwoofer to line level components such as pre-amplifier, integrated amplifier and surround sound processors with pre-amplifier outputs. If you only have one set of pre-amplifier outputs you will need to have a Y connector (split lead) to feed both the amplifier and subwoofer. The high level output filters do not work when RCA phono inputs are used.
Plugging in the Subwoofer Once all the speaker cables are in place you are ready to plug in the subwoofer. Set the bass level to minimum then plug in your mains cable. At switch on your subwoofer will be in stand-by mode. The subwoofer will remain in stand-by mode until a signal is sensed at the input. If the subwoofer is not active for a period of around fifteen minutes, the unit will switch back into stand-by mode.
Troubleshooting No sound from the subwoofer • • • • Check that the power connection is made correctly Check to see if the power light is on Check the input connections to the subwoofer are correct If the high level input is in use, check the connections are phased Excessive bass from subwoofer • • Check the position of subwoofer - ensure that it is not too close to a corner of the room Re-check the setting up procedure Inadequate bass from subwoofer • Re-check full setting up procedure Vibrating noise
