Nady Audio GEQ 131, Owner'S Manual

9.

IEC Power Cord Receptacle 

This is used to connect the AC power source to your equalizer.
Power requirements: 115/230VAC, 50/60Hz

10. AC Voltage Selector
Set this slide switch to match your line voltage supply. 
CAUTION:  For new installations and portable sound systems, or
in any situation in which the AC power is suspect, it is wise to
confirm appropriate voltage and line polarity BEFORE connecting
the instrument to the power source.

11. Fuse Holder
This fuse holder contains an AC primary fuse.  This fuse should
be replaced with the same type fuse when this is blown out.  If
they continuously blow, stop replacing the fuse and refer
servicing to qualified personnel.  
CAUTION:  After checking the AC supply voltage, be sure that
the correct fuse is in the fuse holder: 0.5 Amp for 100-130VAC
and for 220-240V AC.

12. Ground-Lift Switch
This switch is used to disconnect the signal ground from the AC
power and chassis earth ground.  This switch should be put in the
LIFT position if the speakers produce humming sounds caused
by a ground loop.

13. Input/Output Connectors
See INPUT/OUTPUT CONNECTIONS section (page 2) for
proper wiring of the XLR, 1/4" TRS and RCA connectors for
desired active balanced or unbalanced operation.
Paralleling inputs and outputs may be accomplished by using any
of the 3 connectors. Note: The 1/4" TRS connectors are normally
used for this function.
Note: while you can use any input connector with any output con-
nector, only one of these connectors is to be used at a time.
