tænd og sluk

Tænd/sluk omskifteren (fig. A 5) afbryder ikke helt for subwooferens forstærker. Et lille kredsløb vil have et lavt forbrug. Skal

forstærkeren afbrydes helt fra nettet, stilles hovedafbryderen (fig. A 11) til ”OFF”.

power-omskifteren (fig. A 5) har tre stillinger:

ON med omskifteren i denne position er subwooferen aktiv, og indikatoren lyser rødt.

AUTO når omskifteren stilles i denne position vil subwooferen i starten være aktiv, og indikatoren lyser rødt. Efter ca. 10

minutter uden signal vil indikatoren slukke og subwooferen går i standby. Når et signal detekteres på en af

indgangene vil subwooferen omgående skifte til aktiv og indikatoren lyser rødt.

OFF i denne stilling er subwooferen i konstant standby og indikatoren er slukket.

hvis subwooferen ikke skal bruges i en længere periode, anbefales det at afbryde på hovedafbryderen (fig. A 11) eller at fjerne

strømkablet fra netforsyningen.

set up

start with the main switch ”OFF”. Two other switches and two settings also need to be regulated:

The ON/OFF switch (figure A 5) Set to ”ON” or ””AUTO”. AUTO is the most energy conscious as the amplifier is only turned on when

a signal reaches the unit.

Phase setting (figure A 6) Normally, ”0” is selected, where the subwoofer operates in phase with the other speakers in the

system. The acoustics in the room and the distance between the listener and the subwoofer will

sometimes combine to make ”180” the preferable option. Try listening to the two settings.

Crossover frequency (fig. A 3) Regulates the highest frequency the subwoofer works up to. The bigger the speakers in the system,

the lower the subwoofer ought to work. If the amplifier in the system has an adjustable subwoofer

frequency the frequency of the latter must be identical with the subwoofer.

An initial setting might be 80 Hz (the 11 o’clock position).

Volume control (figure A 2) The volume control is used to adjust the sound level from the subwoofer. E.g., start at the 9 o’clock

position.

indstilling

Begynd med hovedafbryderen i ”OFF”. Derudover er der to omskiftere og to reguleringer at tage hensyn til:

Tænd/sluk omskifter (fig. A 2) Vælg ”ON” eller ””AUTO”. Auto sparer mest energi, da forstærkeren kun er tændt når der er signal

fra anlægget.

Fase omskifter (fig. A 6) Normalt vælges ”0” hvor subwooferen arbejder i fase med de øvrige højttalere i anlægget. Som følge

af rumakustik og afstanden mellem lyttepositionen og subwooferen kan det dog i enkelte tilfælde

være en fordel at vælge ”180”. Prøv at lytte forskel på de to indstillinger.

Delefrekvens (fig. A 3) Reguleringen sætter den højeste frekvens som subwooferen arbejder op til. Jo større højttalere der

er i systemet, jo lavere bør subwooferen arbejde. Hvis surroundforstærkeren i systemet har justerbar

subwooferfrekvens bør denne frekvens indstilles identisk på subwooferen.

Som udgangspunkt kan reguleringen sættes på 80 Hz (knappen i klokken 11 position).

Styrkeregulering (fig. A 2) Styrkereguleringen bruges til at indstille lydniveauet fra subwooferen. Start med reguleringen på

f.eks. klokken 9 position.

fine-tuning

After connecting and setting up as above it is now time for the first trial run and fine-tuning. Turn on the main switch (figure A 11).

Select a CD / DVD with plenty of deep bass. To fine tune the subwoofer in a home cinema, we recommend the use of a music DVD. Do

not use sound tracks from action films for fine-tuning. The sound effects on them are usually too brief and loud to fine-tune properly.

Set the volume control on the system to an appropriately loud level. It is important to evaluate the sound from your favourite listening

position, so we recommend somebody else helps adjust the settings.

Listen to the music for an extended period and evaluate the subwoofer’s performance:

If there is there too much or too little deep bass then turn the volume control down/up (figure A 2)

does the bass sound good along with the other speakers in the system? If not, regulate the crossover frequency

(figure A 3).

if the subwoofer is overburdened, it sounds wrong. In that case turn down the volume control (figure A 2) and the

crossover frequency (figure A3). If the subwoofer is overburdened, it may also be due to the fact that you need to

change from sealed chamber to bass reflex (bass reflex is the most efficient).

please note that the position in the room also affects the sound.
