5 QUICK SETUP GUIDE This quick set-up guide assumes some knowledge with regards to inst alling, connecting and using a subwoofer . We strongly recommend that you do read through the instruction manual in order to get the best performance from your Dynaudio subwoofer , even if you already have inst alled the subwoofer . Inst alling: • Carefully un[...]

6 INST ALLA TION & CONNECTIONS Unp acking Due to it s weight and size, we strongly recommend that help is at hand when unp acking and inst alling the subwoofer . Unpack the subwoofer on a clean, even and sof t area; floor carpeting is very suit able. Please refer to Fig. 1. • The packaging should be opened from the top. Remove all accessories[...]

8 SETTING UP & TUNING IN Master and Slave mode The subwoofer can operate in two different modes: Master or Slave mode. If your system consists of multiple subwoofers, it is desirable that all subwoofers operate with identical settings (V olume, Low-Pass filter (Hz), Phase and LF Extension). Using the Master/Slave feature of Dynaudio subwoofers [...]

9 SETTING UP & TUNING IN Connecting using the XLR socket s A balanced signal connection (XLR sockets) provides a connection that is far less susceptible to cable signal interference compared to an unbalanced connection (RCA connection). It is for this reason that XLR and balanced connections are used almost exclusively in critical and professio[...]

10 SETTING UP & TUNING IN Adjusting the settings and using the subwoofer Once you have ensured yourself that all necessary connections have been made, the subwoofer can be switched on and used. With the exception of the mains power switch (No. 2 in fig. 2) controlling the subwoofer is done through the DSC 1 remote control; the numbering at the [...]

12 SETTING UP & TUNING IN Setting the Cross-over Frequency The Cross-over frequency can be set to four positions: 60, 80, 100Hz and Flat. The roll-of f slope is 24dB per octave. In most cases, selecting cross-over frequencies is done through the bass-management system of your processor or receiver . In this case, use the "Flat" positi[...]

13 POSITIONING THE SUBWOOFER stored settings has been overwritten with your new settings. • T o avoid accidental over-writing of presets, set the Preset/Settings switch on the subwoofers back panel (No. 8 in fig. 2) to the "Protect" position. Adjustments on- the-fly for all settings are still possible. T o recall a Preset: • Simply br[...]

14 POSITIONING THE SUBWOOFER Fig. 8 • Generally , avoid placing the subwoofer at ¼, ½ or ¾ of either the length or width of the room as at these locations the room-modes are likely to be strongest (the dashed lines in fig. 8) Fig. 9 Corner placement Maximum boost of bass level but potentially uneven distribution of bass in the room (room-modes[...]

15 FINDING THE OPTIMAL SETTINGS Multiple subwoofers. By using carefully positioned multiple subwoofers it is pos- sible to even out the different room-modes and thus create a more coherent overall bass response in the room. It is worth experimenting with different locations around the room for the additional subwoofers, even using the rear of the r[...]

16 FINDING OPTIMAL SETTINGS frequency response; see fig. 13. In the same manner , with the cross-over frequency for the main speakers set too low (cross-over freq. for the subwoofer too high), there will be too much of an overlap between subwoofer and main speakers, again resulting in incorrect overall frequency response; see fig. 14. Correct setti[...]

17 FINDING OPTIMAL SETTINGS • Listen carefully to the bass-line played by the instrument. As it goes up and down in the bass range, the overall bass volume should remain the same, be it with very deep or higher bass notes. Particularly with very small main speakers, it may be that you can hear a "hole" in the bass response: Y ou can hea[...]

18 TROUBLESHOOTING Problem Cause Solution The subwoofer switches itself of f while music is being played • There is hardly any low-frequency signal available in the signal. This can happen if the music or movie itself does not contain very low frequencies (e.g. long dialogues) and if the processor or receiver already performs bass-management. •[...]
