APP „SUB CONTROL 3.0"
5 POWER MODE:
6 PARAMETRIC EQs:
The „POWER MODE" function is used to activate or deactivate the auto-on func-
tion.
„AUTO ON" is the normal setting. The ELAC subwoofer is kept in power-saving
stand-by model (LED glows very dim). A sensor continuously monitors the in-
puts. Once a sufficiently strong bass signal is detected, the power output stage
is activated. Within a few tenths of a second, the subwoofer is ready for opera-
tion and the LED glows brighter.
If no further input signals are detected, the ELAC subwoofer remains for approxi-
mately 15 minutes in fully operational mode before returning to stand-by mode.
The sensitivity of the auto-on function („AUTO ON THRESHOLD") can be set
from 1 – 10 mV. The correct sensitivity for your application will depend on the
(pre-) amplifier used. A value of between 3 and 6 is generally suitable.
If POWER MODE "ALWAYS ON" is selected, the subwoofer is permanently fully
activated and will no longer switch to stand-by mode.
Your subwoofer comes with eight adjustable parametric equalizers. Each of the
eight equalizers allow you to adjust the „CENTRAL FREQUENCY" as well as the
„BANDWIDTH" and „GAIN" settings. This not only allows you to boost specific
frequency ranges but also lets you selectively filter out annoying room reso-
nances („droning" or „booming bass").
To attenuate an annoying room resonance, you must first pinpoint the frequency
that is causing it. The most effective method is to use a test CD of pure tones in
the bass frequency range. Start by playing the bass notes in sequence. If one
bass note sounds unnaturally loud, this is the room resonance that you can
damp with the help of one of the eight equalizers. To do this, set the LOW PASS
FREQUENCY control to the frequency determined using the test CD. Select a
„NARROW" bandwidth and reduce the GAIN control until the bass note is repro-
duced with the same apparent loudness as the other frequencies.
To selectively boost a particular frequency range, you should increase the band-
width slightly (move the control towards „WIDE") and then carefully adjust the
„GAIN" setting to avoid any unnatural „droning" in the sound reproduction.
