Input sensitivity

Adjusts the input sensitivity to match the output level of your pre-amplifier or audio-visual processor.

Setting Input Sensitivity

The wide variety of possible source equipment types that can be connected to an active subwoofer means that it
is important to set the input sensitivity appropriately. Doing so will help ensure that the subwoofer’s volume
adjustment range is adequate and that its input and DSP electronics are driven properly.

If the source equipment has a published specification for output level, begin by setting the Sub 6 input sensitivity
to match the specification as shown in this table:

Source Output Level Sub 6 Setting

<1.0 V

+6 dB

<2.0 V

0 dB

<4.0 V

-6 dB

<10 V

-14 dB

The -14 dB sensitivity setting should generally be used when the Sub 6 is used for the LFE channel in a home
theatre system.

If the source equipment has no published output level specification, begin by setting the Input Sensitivity to -6 dB.
If then when in use the Sub 6 volume setting is required to be towards either its maximum or minimum values,
adjust the Input Sensitivity appropriately such that the volume setting is towards the middle of its range.

Preset

The Sub 6 incorporates low pass filter presets for a range of Dynaudio speaker models.

If your Sub 6 is to be used in a system with one of the Dynaudio models listed, select it to automatically configure
the Sub 6 low pass filter appropriately.

If your Dynaudio speaker model is not listed among the Sub 6 presets, or if your Sub 6 is to be used with
speakers from an alternative manufacturer, select a low pass filter frequency closest to the speaker’s specified
-6dB low frequency cut-off. Unlike the specific Dynaudio loudspeaker filters, these low pass filters are of a 4th
order Linkwitz-Riley type.

Alternatively, you may wish to use the 80Hz high-pass 4th order Linkwitz-Riley filter on the Left/Right outputs, in
this case the 80Hz low pass filter should offer the best matched crossover.

If your subwoofer is to be used for the LFE channel in a home theatre system select the filter Bypass option.

Note

Matching the filter frequency of the subwoofer to the bass cut-off frequency of the main speakers will have an
important impact on the overall system sound quality. In general, larger main speakers will have more extended
bass so will require a lower subwoofer filter frequency. Conversely, smaller main speakers are likely to require a
higher subwoofer filter frequency. If the subwoofer filter frequency is not set optimally, the overall frequency
response of the system may display an audible peak or dip around the crossover frequency. The diagram
opposite illustrates the three frequency response characteristics that might result from optimum and non-
optimum subwoofer filter settings.
