2.1 Unpacking and Inspection
Before unpacking the unit, inspect the outer carton for shipping damage. If the car-
ton shows damage, inspect the unit in those areas. Please save the carefully designed
shipping carton and packing materials. In the unlikely event that the unit needs to be
returned to the factory, alternate cartons or packing materials may not be adequate
and can cause damage not covered by warranty.
The following essential items are provided with the unit:
• Two power cords (style to match shipping location).
• Small bag with replacement fuses and a handy permanent marker.
• This manual.
• Warranty information: Please fill out and return the warranty card to Linear
Acoustic to ensure your software and documentation are kept up to date.
2.2 Installation
StreamStacker LA-5448 installation requires:
• One standard rack space units with ADEQUATE VENTILATION (the unit uses
convection cooling via vents on the left and right sides of the unit);
• standard 75
:
BNC cables for digital signal connections;
To connect to digital equipment with 110
:
XLR connectors, we strongly recommend
the use of impedance-matching transformers (baluns) which are available from Canare,
Neutrik and other manufacturers. We know it is tempting to use shortcuts, and they
will sometimes work just fine, however failure of such approaches are usually random
and always seem to happen during the most expensive programming. We encourage
the use of the inexpensive and widely available baluns, especially in a transmission en-
vironment.
