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 215 is balanced, with
pin 2 “hot.” From the line level outputs preceding the GE 215, connect a pair of XLR male connectors to the rear panel
INPUT jacks, paying attention to pertinent Left, Right, Channel 1, Channel 2, north, south, etc. Connect female XLR
connectors to the rear panel OUTPUT jacks, 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 controls at “7”
(corresponds to about 2 o’clock), depress the BYPASS switches. If any difference in level exists, adjust each channel’s
LEVEL control so the same volume exists whether it’s BYPASS is in or out. You now have an expensive jumper wire.
Fully utilizing the capabilities of the GE 215 requires moving some of the sliders, but you already knew that. To make best
use of the GE 215, use some sort of an analyzer to help 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.
GE 215 CONNECTION
When first connecting the GE 215 to other components,
connect the power supply 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 are no
performance trade-offs. The wiring convention adheres to
American, British and International standards of pin 2 being
hot (+), pin 3 being return (–), and pin 1 being 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.
OUTPUTS
The Outputs mimic the Inputs. Balanced output requires
using pin 2 and pin 3 for the signal. 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 215. These require a mic preamp.
