INTRODUCTION Congratulations! Thank you for purchasing this Dynaudio subwoofer. With it, you have chosen for the latest in audio technology and engineering, culminating into the finest in audio reproduction. With their dynamic, accurate performance and ease of integration into even elaborate systems, Dynaudio subwoofers are ideally suited to obtain maximum enjoyment from High-Resolution formats such as DVD-Audio™ and SACD™.
QUICK SETUP GUIDE This quick set-up guide assumes some knowledge with regards to installing, 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 installed the subwoofer. Installing: • Carefully unpack the subwoofer and accessories. • Install the battery cell in the remote control.
INSTALLATION & CONNECTIONS Unpacking Due to its weight and size, we strongly recommend that help is at hand when unpacking and installing the subwoofer. Unpack the subwoofer on a clean, even and soft area; floor carpeting is very suitable. Please refer to Fig. 1. • The packaging should be opened from the top. Remove all accessories that come packed with the subwoofer, such as AC power cord, remote control and warranty card). Do not remove the top part of the protective material.

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 (Volume, Low-Pass filter (Hz), Phase and LF Extension).
SETTING UP & TUNING IN Connecting using the XLR sockets 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 professional installations. Fig. 5 Provided your processor or receiver has a XLR symmetric or balanced Output for subwoofer you should consider using the XLR Input (No.
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 beginning of each section corresponds to the numbering in fig. 6. Fig.
SETTING UP & TUNING IN Fig. 7 1 2 3 The subwoofer can be switched from Standby either manually or automatically. The subwoofer is factory-set at Automatic, as this will be the most convenient setting in most cases. Back to Automatic mode: Press either the "I" or "O" button briefly. Regardless if the subwoofer is switched On or in Standby mode, the subwoofer will switch back to Automatic mode again: The Manual status LED will extinguish. 1 Manual Mode (Manual/Automatic) LED.
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-off 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" position. Refer to the instruction manual of the processor or receiver how to set cross-over frequency. • The EXT mode is disabled when the subwoofer is set to "Slave" mode.
POSITIONING THE SUBWOOFER stored settings has been overwritten with your new settings. • To 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 onthe-fly for all settings are still possible. To recall a Preset: • Simply briefly press the desired Preset button A, B, C or D. • Presets can only be stored or recalled in "Master" mode.
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 This position still provides considerable boost but less than the corner placement as above. Room-modes can also still be considerable but less so than with corner placement. From the listening position, check if the bass is even across the entire bass spectrum.
FINDING THE OPTIMAL SETTINGS Multiple subwoofers. By using carefully positioned multiple subwoofers it is possible 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 room.
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 settings are illustrated in fig. 15. Fig. 15 Subwoofer & main speakers cross-over frequencies set correctly: Smooth frequency response. Fig.
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: You can hear the deepest bass notes and everything from lower midrange easily, but overall the bass leaves a thin impression.
TROUBLESHOOTING Problem Cause The subwoofer switches itself off while music is being played • There is hardly any low-frequency signal • Use the temporary manual On/Standby available in the signal. This can happen if facility by pressing the green "I" button on the music or movie itself does not contain the remote for more than two seconds. very low frequencies (e.g. long dialogues) and if the processor or receiver already performs bass-management.
FACTORY DEFAULTS Factory Default settings. The factory default settings are as follows: Power Mode: Automatic Phase: 0° Level: 0dB EXT: On LF Cut-off: 100Hz To reinstate the factory default settings: • Switch the subwoofer off completely using the switch on the back panel (No.2 in fig.2). • Wait for at least 10 seconds. • Press and hold the "A" preset button (No. 6 in fig 6). • While holding down the "A" preset button, switch on subwoofer back on: The power Status LED will start to flash green.
