FUSE: This is the A.C. Mains Fuse for the BIG BLOCK 750. REPLACE ONLY WITH A SLO-BLO TYPE FUSE OF THE PROPER RATING. THIS IS EXTREMELY IMPORTANT, AS THE BIG BLOCK 750 DRAWS A SUBSTANTIAL AMOUNT OF CUR-

RENT AT HIGH OUTPUT LEVEL SETTINGS.

The removable “Euro” Style” A.C. cord that is supplied with the BIG BLOCK 750 makes set-ups and tear-downs after the gig a snap. It also makes de-racking much easier when you wish to remove the unit from a hard wired rack system where all the A.C. cords have been cabletied in. Additional heavy duty cords are available should you ever need one...simply call us direct and we can ship one directly to you for a nominal charge, plus shipping cost. Make sure the A.C. cord is firmly in its socket (receptacle) before powering up the amplifier.

NOTE: NEVER ALTER THE THREE PRONG POWER CORD IN ANY WAY.

GROUND LIFT / POST & PRE / DIRECT OUT: This section captures the entire pre-amp signal including the Parametric EQ, the Compressor and the Effects Loop and allows you to send a Balanced signal to either a House Main Board or a Recording console. There are four elements to this circuit which are; (1) a male XLR jack, (2) a LEVEL control, (3) a POST / PRE switch and (4) a

GROUND LIFT switch. Here are their functions and how to use them.

LEVEL

LEVEL: This rotary control allows you to set an appropriate level for the Direct Signal to match the input sensitivity of the console. It is always best to start with the LEVEL control zeroed-out before connecting a cable to the DIRECT output. This practice will help to avoid accidental damage to the speakers or your enginneers’ ears from too hot a setting upon hitting your first note.

POST / PRE: This switch lets you choose the type of signal you wish to send to the console. POST gives you the entire sound of the pre-amp with the Parametric EQ, Compressor and the Effects Loop (including processing from anything in the loop).
