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.

•Press the button for the desired position. When pressing the button, ensure that the command from the remote control is received (the Power Status LED; No. 2 in fig. 7 blinks).

Check the owner's manual of the other speakers in the system if a specific frequency is recommended. Please refer to the chapter "Finding the optimal settings" for more information.

• Together with the other settings, the Cross-over frequency can be stored in one of the 4 presets. Refer to section "Storing and recalling Presets" in this chapter. Together with the other settings Volume and Phase we recommend that, once found, you store the correct cross-over frequency into one of the presets.

•The Cross-over frequency control is disabled when the subwoofer is set to "Slave" mode. Refer also to section "Master and Slave Mode" in this chapter.

Selecting EXT On or Off

EXT stands for Extension, in this case Low Frequency Extension. Dynaudio subwoofers allow for deep and accurate bass response even at high levels. In the EXT Off mode, the very deepest bass will be mildly filtered; this will allow the subwoofer to achieve even higher sound pressure levels. Generally speaking, this setting is best suited for movies and most music. Some movies and high quality, audiophile recordings can contain extreme low frequencies. To experience these:

•Press the EXT On button (lower button in No. 4, fig. 6) to switch Low Frequency extension on.

•Together with the other settings, the Low Frequency Extension status can be stored in one of the 4 presets. This way, you can program the EXT switched On as part of a setting for "audiophile listening" and program EXT Off as part of a setting for "cinema mode" for instance. Refer to section "Storing and recalling Presets" in this chapter.

•If you use a turntable, you will get the best results with EXT switched off. Many vinyl records contain, and the turntable itself will generate, very low frequencies (rumble) which, with the subwoofers low frequencies capabilities can otherwise prove distracting from enjoying the music.

•The EXT mode is disabled when the subwoofer is set to "Slave" mode. Refer also to section "Master and Slave Mode" in this chapter.

• Loud volume levels over prolonged periods of time can cause permanent damage to your hearing!

Setting Phase

The Phase setting of the subwoofer has been factory-set at 0° which in many cases will be the appropriate setting. Press the 0°, 90°, 180° or 270° button (No. 5, fig. 6) to select the desired phase setting.

• Together with the other settings, the Phase setting can be stored in one of the 4 presets. Refer to section "Storing and recalling Presets" in this chapter. Together with the other settings, Volume and Cross-over frequency, we recommend that, once found, you store the correct phase setting into one of the presets.

•The Phase selector is disabled when the subwoofer is set to "Slave" mode. Refer also to section "Master and Slave Mode" in this chapter.

Storing and recalling presets

With four presets available you have the flexibility of recalling different sets of subwoofer settings, depending on what suits the occasion best. For instance, you may store the settings best suited for classical music setting under Preset A, program Preset B to have the best settings for action movies and program Preset C for late-night listening, etc.

The presets are also an excellent tool for recalling different settings when experimenting with either location or settings of the subwoofer.

Once you have stored all presets, you can choose to block access to storing, so that presets can not be over-written by mistake.

Each preset stores settings for Volume Level, Cross-over frequency, LF Extension and Phase.

To store a preset:

•Ensure that Preset programming hasn't been blocked: The Preset/Settings switch on the subwoofers back panel (No. 8 in fig. 2) must be in the "Store" position.

•Set all parameters (Volume Level, Cross-over frequency, LF Extension and Phase) to your liking.

•Press and hold the desired Preset A, B, C or D button (No. 6 in fig. 6) for 3 seconds. Ensure that the subwoofer receives the commands from the remote control without interruption.

•The Status LED (No. 2 in fig. 7) will blink 3 times to confirm the preset has been stored. Any previously
