frequency performance is unaffected by supply-line noise and temperature fluctua-
lions. There is no current limiting, and the amplifiers will drive fully reactive loads.
Soundstream amplifiers can be bridged to deliver high power into a single channel.
The D200 features dual-monaural construction, with
supplies. The Class-A-50 & Class-A-40 operate in pure Class A mode for the
ultimate in sonic transparency. And despite their technologicat sophistication, the
Soundstream amplifiers are elegantly simple in design.
INSTALLATION
Proper installation and adjustment will reward you with reliable operation and
optimum performance. Automotive sound system installations can be tricky, espe-
cially for first-timers.
For this reason, you may want to consider using a pro-
fessional installer who has the tools and more Importantly, the experience to
do the job right.
If you decide to install your equipment yourself, we hope that
this manual will serve as a helpful guide.
L O C A T I O N & M O U N T I N G
The first step in installation is thorough planning. Choose the location for your
amplifier carefully. The amplifier should be located in either the passenger
compartment or the trunk, never in the engine compartment or in any outside
location exposed to dirt and moisture. Adequate ventilation is important; allow
enough space so that air can circulate around the heat sinks. If the amplifier is
mounted vertically, mounting the heat sink fins vertically will optimize heat
dissipation.
The Class-A-50 & Class-A-40 in particular tend to run hot because of Class A
operation. This is no cause for concern provided that ventilation is adequate.
Make sure that the installed amplifier will not interfere with normal operation of
the car. For example, if you locate the amplifier under a front seat, make sure
that it does not interfere with seat adjustment, that it will not be exposed by
repositioning the seat, and that the seat does not press on the amplifier when
occupied. If you install the amplifier in your trunk, make sure that it is not an
obstruction.
It is best not to locate the amplifier near your antenna, because the switching
power supply can interfere with AM reception.
Your amplifier should be mounted firmly to your car's interior with the four
screws/washers provided. Use your amplifier as a template for making pencil-
marks where you intend to drill. (Do not operate your drill through these mount-
ing holes.)
