* This automatic system can be disabled and, if desired, the settings can be set manually using RS232 commands sent
to each individual loudspeaker and subwoofer; for example, if there is a requirement to lock the user out of being able
to change the settings from the controller product. See

RS232 command set

on page 22 of this guide.

Important:

Important: In the absence of any adjustment using RS232 commands, the DSW600 will operate without any low-pass
filter activated and will attempt to play the whole frequency range of the audio it receives.

Augmentation of other loudspeakers

If the DSW600 is being used to augment the bass of one or more loudspeakers within a surround-sound system, at
least one setting will need to be adjusted by sending RS232 commands to the DSW600.

See RS232 section below.

Sub

filter

should be set to either

Sub1

(80Hz) or

Sub2

(120Hz) so the DSW600 plays only bass frequencies. The option

then exists to set the corresponding high-pass filter on the loudspeaker being augmented on the loudspeaker being
augmented to either

Sub1

Sub2

to create a true crossover between the loudspeaker and the DSW600. If the

loudspeaker is left on its default settings, it will attempt to play full-range bass, providing potential for over-accentuation
of some bass frequencies. Refer to the user-guide for the loudspeaker in question for how to set the filter. Once the
crossover is implemented, the sound from the DSW600 should integrated with the sound from the loudspeaker(s) by
adjusting

Sub gain

and

Sub mode

on the DSW600 using RS232 commands. Listening tests and adjustments should

be made with the aim of blending the sound into a single coherent source of audio.

If the DSW600 is being fed from the dedicated Mono or LFE subwoofer channel generated by a Meridian Surround
Controller, the subwoofer filter (crossover) and the subwoofer gain are adjusted as part of the configuration and
calibration process of the system. There is no need to adjust

on the DSW600 itself. Also, by

default

Sub mode

of the DSW600 is set to “Music” so its bass response is extended as shown in the graph above. This

is usually appropriate for this type of application but can be changed to “Music” if desired by the sending the relevant
RS232 command to the subwoofer itself. See
