CONNECTION ALTERNATIVES:
-Speaker level input
Connect the speaker outputs of the stereo power amplifier to ”left (L) &
right (R) "
SPEAKER LEVEL IN"
respectively, fig. 2
- Surround system connections
Surround amplifiers provide a separate subwoofer line output, use a "Line
Cable" from this output to LINE IN right (R), fig. 3. You can also use a "Split
Cable" to connect the subwoofer line output to both LINE IN, left (L) and
right (R), fig.4. The sensitivity then increases with 6 dB.
2-chanel stereo connections
-Line level input
Should your amplifier have separate pre-amplifier outputs, you should
connect those to LINE IN, left (L) and right (R). Use a "Stereo Line Cable".
Your front speakers remain connected to the loudspeaker outputs of the
stereo amplifier.
SOUND ADJUSTMENTS
LEVEL control
This control is used to adjust the balance between subwoofer and front or
satellite speakers. Once you have found a pleasant balance there should
be little need for further adjustments. Trust your ears and your personal
taste to find the correct setting.
LOW-PASS FREQUENCY control.
The active crossover network of the DLS Q-sub 8 can be continuously ad-
justed from 50 to 120 Hz. This frequency is the split frequency between the
subwoofer and the front or satellite speakers. A higher crossover frequency
eases the load of the front speakers while a lower crossover improves the
stereo image. As with the level control you need to try out what suits your
equipment, room and ears the best.
PHASE control.
This switch changes the phase of the subwoofer sound continuously from
0 to180°. Normal position is 0°, but for reasons of placement it could oc-
cur that subwoofer and front speakers are out of phase at the crossover
frequency
You recognize this as weak bass reproduction that just barely can be adjusted
with the level control. Instead you adjust the phase. Turn the control slowly
clockwise while playing music until you here the bass sound improve, your
ears are the proper instrument to decide when the sound is correct.
