Rane GE 30 Operator's Manual

OPERATORS MANUAL

QUICK START

If you are one of those people who think owner's manuals are included with a product to help absorb shock and vibra-
tion 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.
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
connected 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 unnecessary 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.
WEAR PARTS: This product contains no wear parts.

GRAPHIC EQUALIZER

OUTPUTS are balanced as well and follow the same
convention 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 unbalanced 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 trans-
former 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.
