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.
