GE 30 CONNECTION

When connecting the GE 30 to other components in your 

system for the first time, leave the power supply for last. This will 

give you a chance to make mistakes and correct them before any 

damage is done.

INPUTS

 on the GE 30 are balanced. They may be con-

nected for either balanced or unbalanced operation. This product 

offers the choice between going in and out of it using either the 

3-pin connectors or the handsome black #6 terminal strips with 

the finely plated screws. We will describe here the use of the 3-

pin connectors. The terminal strips are connected in parallel and 

are used in the same way. Only the names have been changed. 

Pin 2 is hot “+”, pin 3 is return “–”, and pin 1 is chassis ground. 

Balanced inputs require the use of pins 2 and 3. Pin 1 is unnec-

essary unless you are using it for shield ground. For unbalanced 

operation, pins 1 and 3 must be shorted together to prevent 6 dB 

of gain reduction. Drive pin 2 as hot and the combination of 1 

and 3 as ground.

OUTPUTS

 are balanced as well and follow the same con-

vention as the inputs. There are some tricky things to be careful 

of at the output. If active balanced operation is your preference, 

hot “+” and return “–” should be all that is required. It does 

not take three wires to conduct a signal from one unit to the 

next. Connect the shield to case or chassis ground. Transformer 

balanced outputs are connected in the same manner. Active un-

balanced output requires “+” and ground only. Use pins 2 and 1 

respectively. In this mode, do not short pins 1 and 3. If, however, 

you are using the transformer coupled mode and are running 

unbalanced, do short pins 1 and 3 or you will get little or no 

output. In case you haven’t noticed, if you plan on throwing the 

selector switch very often it’s a good idea to connect everything 

in a balanced configuration.

QUICK START

If you are one of those people who think owner’s manuals are included with a product to help absorb shock and vibration during 

shipment, you are a lot like we are. This section is for you. You want to fire up your equalizer without wading through a bunch of 

stuff in manuals. Great. Read on. We’ll keep it short.

Set the input LEVEL control to about 6. This is approximately unity gain in the BOOST/CUT mode. (In the CUT-ONLY 

mode the level control should be set to 2 for unity gain.) Your sound system should be set up such that gain or loss is not required in 

the equalizer(s). Set the EQ MODE switch on the rear for the desired operating mode, CUT-ONLY or BOOST/CUT. The LEDs on 

the front illuminate, telling you which mode you are in. Set the OUTPUT MODE switch on the rear for the desired output coupling 

mode (ACTIVE or TRANSFORMER COUPLED). Adjust the LOW CUT and HIGH CUT FILTER controls on the front for 

the desired low and high cut frequencies. Full counterclockwise on the LOW CUT control and full clockwise on the HIGH CUT 

control essentially defeats these functions.

If you read only this section, we assume you know how to set up an equalizer. So set the sliders where you want them and you’re 

outta here.

Never connect anything except an RS 1 or other approved Rane AC power supply to the thing that looks like a telephone 

jack on the rear of the GE 30.

This is an AC input and requires some special attention if you do not have an operational power 

supply EXACTLY like the one that was originally packed with your unit. See the full explanation of the power supply requirements 

elsewhere in this manual.
