Lexicon 480L Owner's Manual
Voltage selector set for 120 V.
The 480L measures 19" wide x 5.25" high x 14.5" deep
(483 x 133 x 368 mm). It can rest on any flat surface, or
it can be mounted in a standard 19-in. (483 mm) relay
rack. Do not install the 480L directly above equipment
which produces significant amounts of heat (such as
power amplifiers); maximum ambient operating tem-
perature is 40
o
C (104
o
F). Do not obstruct the ventilation
exhaust ports on the right side panel, or the air intake
on the front panel.
If the 480L is mounted in a rack or road case, we
recommend that you provide support for the rear of the
chassis during transport to prevent possible damage
from severe mechanical shock.

Power Requirements
The 480L is equipped with a three-pin IEC connector
and detachable power cord, providing chassis ground-
ing to the ac mains line. It can be operated at either 100/
120 Vac or 220/240 Vac, depending on the fuses
installed and the setting of the voltage changeover
board.
Note: Voltage changeover is
described in Appendix D.
The nominal operating voltage set at the Lexicon
factory is indicated by a small protruding pin on the
power connector/fuse holder. Check this voltage set-
ting before applying power to the unit! Power consump-
tion is 70W typical, 180W maximum.
