GE 130 CONNECTION

When first connecting the GE 130 to other components,

leave the power supply for last. This gives you a chance to

make mistakes and correct them without damaging your

fragile speakers, ears and nerves.

INPUTS

Both XLR and Euroblock Inputs are wired in parallel and

are actively balanced. Each works equally well. Choose

strictly from a required hardware point-of-view, there will be

no performance trade-offs. The wiring convention adheres to

American, British and International standards of pin 2 (+) hot,

pin 3 (–) return, and pin 1 shield. Unbalanced operation

involves using only pin 2 or “+” as signal, and pin 1 as shield

or ground. It is not necessary to short any inputs to ground—

it doesn’t hurt, it’s just not necessary. Use pin 1, or the shell,

for shield ground.

QUICK START

So tell me honestly, do you actually read the manuals or do you just want to connect the thing and go? If you are one

of the “gotta go now” crowd please read this short section. Even if you read slowly so as to savor every syllable, it only

takes a couple of minutes and may save more of your valuable time later. The rest of this manual is dedicated to those who

really want to know all the nitty-gritty details.

Wait a minute before plugging in the power supply. Hopefully the equipment to and from the GE 130 is balanced, with

pin 2 “hot.” From the line level output preceding the GE 130, connect a XLR male connector to the INPUT jack on the rear

of the GE 130. Connect a female XLR connector to the OUTPUT jack on the rear of the GE 130, to the next line level

device in the signal chain.

Now plug in the power supply. The yellow POWER LED should illuminate, and if you have an audio source working

and the rest of the signal chain completed, you will hear audio. With sliders centered and the LEVEL control at “7”

(corresponds to about 2 o’clock), depress the BYPASS switch. If any difference in level exists, adjust the LEVEL control

so the same volume exists whether BYPASS is in or out. You now have an expensive jumper wire. Fully utilizing the

capabilities of the GE 130 requires moving some of the sliders, but you already knew that. To make best use of the GE 130,

use some sort of an analyzer to adjust the sliders properly.

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 unit. This is an AC supply 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.

OUTPUTS

The Outputs mimic the Inputs. Balanced output requires

using pin 2 or “+”, and pin 3 for the signal ground. It does not

require pin 1 or shield. The signal exists differentially

between the two balanced leads; ground is not involved. For

hum-free systems ground is used only for shielding.

SIGNAL LEVELS

Signal levels from -10 dBV to +4 dBu are considered

normal and within range (at least 20 dB of headroom exists

above these levels). Do not directly connect microphones

into the GE 130. These require a mic preamp.
