Before operation Connecting the subwoofer CAUTION DAMAGE OF DEVICE DUE TO IMPROPER CONNECTION! Set the mains power switch to OFF before connecting the SUB 250. Only switch the subwoofer on (mains power switch to ON) after all connections and set up steps have been properly completed. Note: • The Dynaudio SUB 250 can be controlled by any source provided with a LFE or preamplifier output. In the operating manual the expression “processor/receiver” will be used for all these sources. SUB I/O L

Operation Connecting loudspeakers In Home Cinema systems the bass management - meaning the distribution of the low frequencies to the subwoofer and the speakers - is handled by the settings of the processor/receiver. If your equipment does not provide bass management, or if you want to use the SUB 250 together with a common stereo, the low frequency adjustment of the connected speakers can be managed by the SUB 250. This not Front Out/ LFE/SUB Out Pre Out only improves the sound by matchin

Operation Adjusting the volume (GAIN) CAUTION HIGH SOUND LEVELS! To avoid auditory defects do not listen to high sound levels over a longer period of time. The correct volume setting is an important aspect in achieving a well balanced speaker combination. Please also refer to “Specific tips” on page 16 for further information or ask your local Dynaudio dealer for assistance. Adjust the GAIN control, until correct setting is reached. Note: • You can not adjust the volume, when subwoofer is

Operation Setting the phase (PHASE) With the phase settings you can adjust the timing relationship between the subwoofer Combined frequency response Subwoofer and main speakers. If either subwoofer or main speaker are slightly delayed in Main speakers 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, cons

Operation Positioning the subwoofer Although it is often said that the location of a subwoofer in a listening room is not critical (as the human ear can not locate direction at very low frequencies), we recommend that you choose its position carefully. Thus the subwoofer can integrate seamlessly with the other speakers in the system and interact correctly with the room acoustics. All of the following should be taken as rough guidelines; bass response in general is very dependent on the acou

Operation Positioning possibilities Moving the subwoofer closer to walls and corners in particular will generally increase the amount of bass. Although the extra amount of bass can be compensated for by reducing the volume level of the subwoofer relative to the rest of the system, this can result in uneven bass response at the listening position. You can try starting with placement in a corner and experiment by gradually moving it out of the corner or further away from the wall. Try to loca

Optimizing settings/Troubleshooting Cut-off frequencies Matching the frequency responses of subwoofer and speakers has an important 60 Hz 50 Hz 80 Hz 100 Hz impact on the overall sound quality, when integrating a subwoofer into a audio-video- 100 Hz 150 Hz system. In general a large, floor-standing speaker still has significant output in the Flat deeper bass range, whereas a very small speaker will not be able to reproduce deep bass at all. In the first case a bump in the overlapping area wil

Optimizing settings/Troubleshooting Control possibilities The Dynaudio SUB 250 provides two controls to match the frequency response of the subwoofer and the main speakers perfectly: • SUB Lowpass: the upper cut-off frequency of the subwoofer, which can be continuously adjusted between 50 and 150 Hz. Above the selected cut-off frequency the sound pressure level decreases rapidly. • SAT Highpass: the lower cut-off frequency of the main speakers; 60 Hz, 80 Hz or Flat (neutral) can be selected.

Optimizing settings/Troubleshooting CAUTION DAMAGE OF SMALL SATELLITE SPEAKERS! Selecting the correct frequency depends to a large extend on the main speakers. Sometimes main speakers are specifically intended to work with a subwoofer. In such cases, the main speakers can get damaged by a full-range amplifier signal. If in doubt, check the instruction manual for the main speakers for any restrictions. The table below offers some setting tips for different speaker and amplifier combinations.
