Operation
Dynaudio Sub 300/500

Activating the bass extension (EXT)
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.
NOTICE
•
Loud volume levels over prolonged periods of time can cause permanent damage
to your hearing!
To experience these:
X
Press the
EXT ON
button to switch on the low frequency extension .
Note
•
Together with the other settings, the EXT status can be stored in one of the four
presets (refer to
“Storing and Recalling Presets (PRESET)” on page 14). This way,
you can program
EXT
ON
as part of a setting for “audiophile listening” and program
EXT OFF
as part of a setting for “cinema mode” for instance. .
•
If you use a turntable, you will get the best results with
EXT
OFF
. Many vinyl
records contain, and the turntable itself will generate, very low frequencies (rumble)
which, with the subwoofer's 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
“Master and Slave mode” on page 7).
Setting the phase (PHASE)
The phase setting of the subwoofer has been factory set at 0° which in many cases
will be the appropriate setting (for more information about the phase refer to “Phase”
on page 20).
To set the phase
X
Press the
0°, 90°, 180°
or
270°
button to select the desired phase setting.
Note
•
Together with the other settings, the phase setting can be stored in one of the four
presets (refer to “Storing and Recalling Presets (PRESET)” on page 14). Together
with the other settings, volume level 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 “Master and Slave mode” on page 7.
