ADAM Audio Sub15 - Handbuch (Seite 9)

9 Sub15 Manual / English
On the front side you will find indicator LEDs for the operating mode and
the protective circuit. Controls for the satellite filter, a phase switch and Sub
Level/Filter are located on the rear panel of the subwoofer. The following
tips are intended to assist you at using the controls in the best manner.
5.1 LEDs on front panel
There are two LEDs on the front. The upper LED
indicates the operating mode. In case the subwoofer
receives an overload the lower LED will flash red
indicating the function of the protective circuit.
5.2 Controls on the rear panel
a) Subwoofer Phase
With the Phase Switch you can alter the phase of
the subwoofer relative to the satellites. That means
to change the polarity of the subwoofer. Depending
on the distance between woofer and satellites,
either 0° or 180° may be the better position. We
recommend trying out which position sounds better
within your system.
b) Satellite Filter
The satellites in a system can be driven full range or with a 85 Hz high
pass as recommended by Dolby® laboratories for use in surround set-
ups. Recommendation: the main signal should go into the Subwoofer.
Connect your satellites to the Subwoofer output, either via XLR
symmetrical or RCA asymmetrical. In many cases, clarity and dynamic
range of the speakers can be improved if they do not reproduce very
low frequencies since they do not have to deliver big amplitudes.
Please note: If you alter the frequency it is advisable to check if an alteration
of the phase improves the sound quality.
