OPERATORS MANUAL ME 15B
microGRAPHIC EQUALIZER
QUICK START
If this is your first equalizer, please do yourself and your speakers a favor and read the complete manual. “An ounce of
prevention...,” and all that.
You may use either the 3-pin or ¼" TRS connectors for Inputs or Outputs. Hook-up is intuitive. Just follow the
silkscreened instructions on the rear of the unit. Polarity convention is per IEC/ANSI/AES standards of pin 2 positive, pin 3
negative and pin 1 shield. The ME 15B does not invert the signal. Only connect one INPUT type per channel. The 3-pin
and ¼" TRS Inputs do not sum. You may, however, use both types of OUTPUTS simultanesously if desired.
Anyone familiar with other graphic equalizers finds the ME 15B just as familiar. Setting curves is as easy as it is on all
Rane graphics thanks to our innovative constant-Q circuitry. If you feel you want more information on setting up your
curves, please read on.
If you are familiar with equalizers, then hook-up, plug-in, turn-on and go!
ME 15B CONNECTION
When first connecting the ME 15B to other components,
leave the POWER switch off until the very last. This gives
you a chance to make mistakes and correct them without
damaging your fragile speakers, ears and nerves.
INPUTS
Both 3-pin and ¼" TRS 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 or tip
being hot, pin 3 or ring being return, and pin 1 or sleeve being
shield. Unbalanced operation involves using only pin 2 or tip
as signal, and pin 1 or sleeve 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 or tip, and pin 3 or ring 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.
EXPANDING
Expanding and/or daisychaining the Inputs and Outputs
normally uses the ¼" jacks. Three parallel Input connectors
allows driving a second signal processor or amplifier without
special cabling.
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 ME 15B. These require a mic preamp.
