Setting the phase (PHASE)

With the phase settings you can adjust the timing relationship between the subwoofer and main speakers. If either subwoofer or main speaker are slightly delayed in response in relation to the other, it can result in decreased bass output in the frequency response area where they overlap each other.

The phase relationship between subwoofer and satellite speakers is very dependent on relative distance, construction and working principles of the main speakers. The figure on the left shows a case whereby phase of the subwoofer and main speakers are incorrect in the critical overlap area, thus significantly reducing acoustic output in the listening room in that area.

Finding the correct phase setting:

1.Play a bass-rich track which also covers the overlap area.

2.Toggle the PHASE switch between 0° and 180°.

Choose the setting for which you experience the most bass.

Note:

You can not set the phase if the subwoofer is in slave mode. In this case the phase is controlled by the setting of the master subwoofer.

Setting the satellite cut-off frequency (SAT Highpass)

Depending on the bass capabilities of the speakers, the frequency range of subwoofer and speakers can overlap between 50 Hz and 150 Hz. A bump or a gap in the frequency response and thus a lower sound quality will be experienced if the system is not matched properly. In addition, small speakers and low powered amplifiers will particularly be affected by the low frequency signals, which again has an negative effect on the sound quality. Therefore it makes sense to limit the bass range of the connected speakers (called “satellites” in this case) by a highpass filter. The Dynaudio SUB 250 provides three settings to achieve this:

Flat = no limitation

60 Hz = frequencies below 60 Hz are cut-off

80 Hz = frequencies below 80 Hz are cut-off

XSwitch SAT Highpass control to needed position.

Note:

In most audio-video-systems the satellite cut-off frequency is already set in the bass management of your processor/receiver. Please see the operating manual of your processor/receiver for further information. You can decide whether you use the processor/receiver or the subwoofer for setting the cut-off frequency. Just take care, not to set it twice by setting either of them to Flat.
