carton box in case future transportation is needed.
You should immediately contact your dealer if the active subwoofer is damaged.
Installation
1. From amplifier with pre out to subwoofer:

the sound signal runs from amplifier subwoofer pre out to Your active subwoofer.

subwoofer. Make sure that the right channel on the amplifier is connected to the right channel on
the subwoofer. Repeat the same check for the left channels.
Functions (See Fig. 1 on page 11)
Volume
The sound level of the active subwoofer can be adjusted. Use the volume control carefully,
remember that programme material may contain very high energy.
Phase
The phase is adjustable from 0 - 180 degrees. Try different settings for preferred sound.
Crossover
It is possible to reduce the bass - adjustment from 50-150 Hz. Try different settings for preferred
sound.
Placement
Your active subwoofer is designed to re-produce music information in the frequency range below
150Hz. The human ear is not able to localize sound for these low frequencies, this is why the
placement of the subwoofer is not critical.However you can use the nature of the acoustic laws in
the following ways:
a. To get the most amplification of the room itself, place the active subwoofer close to a corner
at a distance of about 10 cm from the walls. If you get to much bass please move the subwoofer
out from the corner. (See drawing A on page 8)
b. By experimenting with the placement of the subwoofer you can optimize the sound quality.
One good rule is to place the subwoofer near the satellite speakers. (See drawing B on page 8)
c. Never cover the built-in amplifier.
Warning!
