Voltage Changeover; Connector Requirements - Lexicon Prime Time 93 Owner's Manual

•
that the voltage changeover switch located inside the unit is set to the
appropriate position and that the unit is appropriately fused: 3/4 A for
115V, 3/8 A for 230V. See section 1.5 for voltage changeover instructions.
But beware that voltages are normally set at the factory and should not be
changed except by a qualified service technician. The unit will draw a
maximum of 35 Watts and will tolerate line voltage variations of +10%.
1.5 VOLTAGE CHANGEOVER
The M.93 can be set to operate at either 115V, 50-60Hz or 230V, 50-60Hz
+10%. The voltage set at the factory will be indicated on the rear panel.
To change the operating voltage, first remove the power cord to avoid con-
tact with power line voltages. Remove the top cover screws and the top
cover. Locate the clear plastic High Voltage protection shield in the front
left hand corner (facing the unit) through which the voltage changeover
switch can be viewed. First look to verify that the switch does not indicate
the desired voltage. If not then remove the plastic shield by depressing
each (one at a time) of the small locking barbs on the three nylon standoffs
while simultaneously lifting the shield at the nearest corner. The barb
can be depressed with a small pliers or screwdriver. Change the fuse, F2,
located beneath the shield to a type 3AG 3/8 Amp slow blow for 230V operation
(or to 3AG 3/4 Amp slow blow for 115V operation). Then flip the voltage
changeover switch, S6, to expose the correct voltage setting (230 or 115).
Snap the insulating plastic shield back onto the nylon standoff making sure
that all the barbs lock in place. Refit the cover. Finally, plug in the
power cord, and verify correct operation.
1.6 CONNECTOR REQUIREMENTS
Standard versions of M.93 require male 3 pin XLR connectors to mate with the
two inputs:
11
INPUT
11
and
11
AUX INPUT
11
•
The MASTER OUTPUT requires a female
3 pin XLR connector. All other rear panel connections require ~~~ standard
phone plugs. An optional version uses tip/ring/sleeve type ~~~ phone jacks
for the two inputs and main output instead of XLR connectors.
