Introduction!
Please read this manual fully before unpacking and installing the pro-
duct. It will help you to optimise the performance of your speakers.
Unpacking and maintenance
Your speaker should be treated with the same care you would treat a
piece of furniture. Use only a piece of soft cloth to clean the loudspea-
kers. After unpacking, we suggest you retain all packing material for
future transports.
Running-in period
The performance of the speaker will change subtly during the listening
period.
Please allow your new speakers to play about 20 hours of music at
normal listening level before doing any critical listening.
System
DLS Flatsub Midi is an efficient, active subwoofer with a built-in 150 Watt
digital power amplifier. The loudspeaker unit is a specially developed,
8”, long-stroke woofer with a powerful magnetic system.
DLS active subwoofers are designed to interact with Hi-Fi equipment,
surround installations and multi-media systems. The subwoofer allows
great freedom in placement. With the control you can adjust phase,
crossover frequency and level, which makes it easy to adjust for the
acoustics in your listening room.
Connecting power supply
The switch "Power" is the on/off switch for the subwoofer. Normal posi-
tion is AUTO ON which makes the subwoofer start with the rest of your
system, POWER LED glows green. After a period without input signal
the amplifier atomatically reverts to standby, POWER LED glows red.
The power switch "OFF" position is used when the subwoofer should
not be used for some time.
CAUTION!
If you hear distortion when you increase the volume this is normally a
sign of overloading the subwoofer and you should immediately reduce
the level. We recommend that you use the volume control with care.
Service
Should your DLS loudspeaker system require service, or if you
have difficulty in achieving the fine performance of which your DLS
loudspeaker system is capable, consult the DLS dealer from whom
the system was purchased. Your dealer has the knowledge required
to provide expert advice and assistance. In case the DLS dealer is
unable to assist you, you are welcome to contact the DLS Technical
Department.
