Cut-off frequencies
Control possibilities
The Dynaudio Sub 600 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. Below the selected cut-off frequency the sound
pressure level decreases rapidly.
Note: The settings for the cross-over frequencies just have an impact on the signal at
the SAT/SUB Input! The LFE channel is just used to reproduce very low frequent
effect signals. Consequently signals at the SUB I/O - LFE/Slave In are not limited
in their frequency response.
General tips
SUB Lowpass = 80 Hz
The cut-off frequency should be selected as low as possible. Then the subwoofer
works without being recognized as a single signal source. Very often a cut-off
frequency of 80 Hz has been experienced as an ideal value.
Reduce weak amplifiers and small speakers from bass load
By limiting the reproduction of low frequency at the SAT Output, amplifiers and
speakers connected to this output are freed from reproducing the heavy bass load,
which negatively impacts the sound quality. This will improve the overall sound of your
audio system.
Play a music track that has a significant amount of bass over a large bass region. An
instrument such as a double-bass or bass-guitar is very suitable. 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.
