DSW DSP Subwoofer
Here you will find all of the information that you require to get the most out of your DSW DSP Subwoofer.

The DSW does not have a mains power switch, so as soon as power is applied to the product, the green LED on back-panel should illuminate dimly. If it does not light up, the mains supply and the mains inlet fuse should be checked.
The DSW comes out of Standby mode when it receives an appropriate communication signal from another Meridian product. This signal is received on the Speakerlink input socket of the DSW and is produced when the rest of the system is brought out of Standby. When this happens, the green LED on the back-panel of the DSW is illuminated brightly.
In Standby mode, the green LED on back-panel illuminates dimly. When out of Standby, the green LED illuminates brightly. As “brightly” and “dimly” are relative terms, it can be useful to watch the LED as the system is brought out of Standby. The change from dim to bright is quite obvious and should confirm whether the product is coming out of Standby mode.
Bass output can be increased, but it may require some configuration. In a two-channel system connected using Speakerlink cables, the default settings mean that when a subwoofer is added, bass frequencies are no longer produced by the main loudspeakers. Rather, bass is diverted to the sub instead of the main loudspeakers. However, some users would prefer to have bass from the sub in addition to the full-range bass already produced from their main loudspeakers. To do this, it is necessary to set the main loudspeakers to produce full-range bass. On loudspeakers with a digital display, this is done through the set-up menu. On loudspeakers without a digital display, it is done using an RS232 command. Once this is done, the subwoofer gain and filter controls can be used to tune the sound to taste. For a full explanation of how to set a particular model of loudspeaker to full-range, refer to its support documentation.
This selects the range of frequencies which are sent to the subwoofer. “Sub1” employs a low-pass filter with a shoulder at approximately 80Hz. “Sub2” is based on approximately 120Hz. The filter to be used can be selected according to personal taste based on listening tests.
No. The DSW requires there to be at least one other Meridian DSP speaker in the system. In Meridian terminology, this is because the DSW always assumes the role of a “Slave”; it cannot act as a “Master” loudspeaker.

Music mode extends the bass response of the DSW down to 10Hz and provides a superior transient response, i.e. it sounds “faster”. Conversely, Movie mode produces a higher level of bass output, but the response is limited to 30Hz. This makes it more appropriate for use with the bass content usually present in movie soundtracks.
If one DSW is used, the switch should be set to “1+2”. This ensures that the DSW plays bass which is present in both the left and right channels of the audio mix. If two DSWs are in use, there are two options: One option is to set both DSWs to “1+2” so the two units produce the same mix of left and right bass. However, in systems where one DSW is close to the left loudspeaker and the other is close to the right loudspeaker it may be beneficial to set the DSWs to produce bass which is specific to the two separate channels. To do this, set the left DSW to “1” so it produces the left channel bass and set the right DSW to “2” so it produces the right channel bass.
If the system configuration includes one subwoofer, the switch should be set to “2”.
Check the Digital Channel Selector switch on the DSW is set to “2”. If the switch is set to “1” or “1+2”, the DSW can attempt to play sounds intended for the centre-channel loudspeaker.
Yes, this is normal and does not indicate any problem with the unit.
