Lexicon 480L Owner's Manual
Behind the Front Panel
Cooling Fan
The cooling fan provides
filtered forced air (the front
panel vent is an air intake).
The filter is removable and
should be cleaned
periodically with mild
detergent and warm water.
Card Retainer
The card retainer ensures
that the HSP and host
processor cards remain
firmly seated.
Output Level Controls
The output levels for the
Main and Aux analog
outputs may be adjusted
independently over a
range from +6 to +24 dBm
(into 600 ohms) with these
controls.
Input Level Controls
The input sensitivity for the
left and right analog inputs
may be adjusted independently
to match inputs
over a range of +8 to +28
dBm with these controls.
Nonvolatile
Cartridge Cable
This ribbon cable connects
the cartridge slot to the
host processor card via a
locking connector on the
host processor card.
Caution: Use of excessive
force when inserting
cards into the 480L can
result in serious damage.
Always make sure that
the connectors are lined
up properly before
applying seating force.
Diagnostic Indicators
The four diagnostic
indicators on the host
processor card flash briefly
upon powerup.
Removable Modules
The 480L is completely
modular. Every subassembly
in the mainframe can
be unplugged and
removed for service or
exchange. The standard
complement for a 480L is
two HSP cards and a host
processor card. The cards
can be plugged into any
slot in the mainframe, but
for best noise performance,
the HSP cards
should be installed in the
two top slots, and the host
processor card directly
beneath them. The empty
bottom slot is provided for
the optional SME card.
