 !Direct Box Hookup 
  
 I use a direct box to run my Hammond into a large PA system. Make sure you use a direct box that has a transformer in it- these are usually the cheap ones. A box that is "active," which will probably require a battery or phantom power, is likely to give you problems. Hit the ground lift button, and hook the inputs of the box up to [G-G]. If you want to get the added harmonics and compression of the Leslie amp in there, you can hit the -20dB pad (and still the ground lift) on your direct box and wire it straight up to the woofer terimals inside the Leslie.

+__SIMPLE LINE OUT FOR THE HAMMOND CONSOLE ORGANS WITH THE PRE-AMPLIFIERS WITH THE GG OUTPUT TERMINALS. By Kon Zissis.___________  
+  
+UNBALANCED LINE OUT  
+  
+You can wire up a 10K ohms log potentiometer as a normal regular volume control to make up a simple fully controllable line out from the output of the pre-amplifiers of the Hammond console organs like I have to my own C3 organ.  
+  
+A new wire connected to one of the two G output terminals will go to the outer pin 3 of the 10K pot, and the signal coming from the middle wiper pin (pin 2 ) of the 10K pot is the variable line out signal going from zero to full volume and this signal will go to the 1/4 phono output socket, and the outer pin 1 of the 10K pot is grounded out.  
+  
+The grounding pin of the 1/4 phono output socket should also be properly grounded to the organ. If you want you can use an RCA socket or any other socket instead of a 1/4 socket  
+  
+You can wire up a 47 uf capacitor in series between the signal coming from the wiper of the 10K pot and the 1/4 line out phono socket in order to prevent any stray leakage DC voltage from a faulty external amplifier or mixer etc going to the 10K pot and to the G output terminal.  
+  
+BALANCED LINE OUT.  
+  
+The above instructions are for a regular unbalanced output but if you want a balanced output line out signal then you can wire up a dual ganged 10K log potentiometer as a regular stereo type volume control with the outer pin 3 of one gang of the 10K dual ganged pot wired as described above for the signal coming from one of the G output terminals and then wiring up the outer pin 3 of the other gang of the 10K dual ganged pot to the other G output terminal.  
+  
+The signal on the middle wiper pin 2 of one gang of the dual ganged 10K pot is the line output signal 1 , and the signal on the middle wiper pin 2 of the dual ganged 10K pot is the opposite phase line output signal 2 so therefore the output signals 1 and 2 are the balanced line out signals which can then go to a stereo 1/4 phono socket or to two separate mono 1/4 phono sockets or to two RCA sockets or to Cannon type sockets etc.  
+  
+The outer pins 1 of both gangs of the dual ganged 10K pot should be shorted together and then grounded out to the organ.  
+  
+Like the unbalanced line out signal wiring described above, you can wire up two 47 uf capacitors in series between the output signals coming from the two middle wiper pins of the dual ganged 10K pot and the corresponding line output sockets in order to protect the dual ganged 10K pot and the GG output terminals of the organ preamplifier from any stray leakage DC voltage coming from the external amplifier or mixer etc.
