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.

Operation Connecting a single subwoofer ➊ To connect the SAT/SUB input: From the preamplifier output of your processor/receiver, PC or mediaplayer (often marked as Pre Out or Front Out) connect a stereo RCA cable to the subwoofer SAT/SUB Input. Front Out/ LFE/SUB Out ➊ ➋ Pre Out This signal should not be already processed by the processor/receiver. Please pay attention to the settings of your processor/receiver. ➋ To connect the LFE channel: From the processor or receiver’s low-level (not

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 Front Out/ LFE/SUB Out adjustment of the connected speakers can be managed by the Sub 250. This not only Pre Out improves the sound by matchin

Operation Adjusting the volume (GAIN) High Sound Levels CAUTION 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 in s

Operation Setting the phase (PHASE) Combined frequency response With the phase settings you can adjust the timing relationship between the subwoofer 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 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 Damage of Small Satellite Speakers CAUTION 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. T
