OPERATORS MANUAL ME 30B

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 connector for Input or Output. 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 30B 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 30B 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 30B CONNECTION

When first connecting the ME 30B 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 sheild 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 30B. These require a mic preamp.

FRONT PANEL DESCRIPTION 1. ON switch: As you have astutely surmised by now, this switch powers up the ME 30B. 2. Filter level slide controls: Each of these sliders controls the output level of each of the bandpass filters. Center position is grounded for guaranteed flat response. 3. OVERLOAD indicator: This red LED lights up if any section of the ME 30B is within 3 dB of clipping.
PAGE 3
REAR PANEL DESCRIPTION 1. 3-pin INPUT jack: This accommodates balanced signals. Rane adheres to the international and U.S. standard for balanced pin configurations: Pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is signal return (negative). Choose between this and the ¼" TRS Input jack—use only one—they do not sum. 2. ¼" TRS INPUT jack: This is a TRS (tip-ring-sleeve) ¼" jack accommodating either balanced or unbalanced signals.

OPERATING INSTRUCTIONS Insuring the proper level of gain though the ME 30B is just as important as adjusting the equalizer bands. Improper gain distribution is a common cause of loss of system headroom and less than optimum noise performance. The OVERLOAD LED informs of an imminent or passed overload to the equalizer. Occasional blinking of the OL with program source material is fine, indicating optimized signalto-noise performance of the ME 30B.
