microGRAPHIC EQUALIZER

Quick Start

If this is your rst equalizer, please do yourself and your speak-

ers a favor and read the complete manual. “An ounce of preven-

tion...,” and all that.

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.

e ME30S does not invert the signal. You may use either the

XLR or ¼" TRS connector for Input or Output. Only connect

one INPUT type per channel. e XLR and ¼" TRS Inputs

WEAR PARTS: is product contains no wear parts.

do not sum. You may, however, use both types of OUTPUTS

simultanesously if desired.

Anyone familiar with other graphic equalizers nds the

ME30S 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!

Manual-2

Front Panel Description

1 LEVEL control: Sets the level of signal coming into the ME30S. Turn this control down if the OverLoad LED lights up steadily

(meaning too strong an Input signal). Since actual unity gain depends on varying slider settings (which is why we have not marked

a unity gain position on the front panel), use the BYPASS switch to determine the exact unity gain position of this LEVEL

control by comparing EQ and BYPASS volumes. e OL indicator lights if any section of the ME30S is within 3 dB of clipping.

Occasional blinking of this LED is acceptable, but if it remains on more than intermittently, turn down either the LEVEL control

or reduce the output level of the preceding component to avoid audible distortion.

2 BY PASS switch: When the red LED is lit, this indicates that the unit is in the BYPASS mode: signal is routed directly from the

Input to the Output without passing through any active circuitry (often referred to as “hard-wire bypass”). Use this switch to

compare equalized and unequalized material, or to bypass the EQ section in the event of power loss or unit failure.

3 Filter RANGE switch: e gain range of the lter sliders is switchable (as a group) from ±6 dB for high resolution, to ±12 dB for

maximum boost/cut capability.

4 Filter level slide controls: Each of these sliders controls the output level of each of the bandpass lters. Center position is

grounded for guaranteed at response.

5 POWER: As you have astutely surmised by now, when the ME30S is plugged into 85-240 VAC, this emits yellow light.

Rear Panel Description

1 XLR INPUT jack: Accommodates balanced signals. Rane adheres to the international and U.S. standard for balanced pin con-

gurations: 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: is TRS (Tip-Ring-Sleeve) ¼" jack accommodates either balanced or unbalanced signals. For an unbal-

anced signal use a mono ¼" plug (single conductor with shield). For a balanced signal use microphone cable (two conductor with

shield) with a TRS ¼" plug. Choose between this and the XLR Input jack—use only one—they do not sum. Refer to the included

RaneNote, “Sound System Interconnection” for unbalanced wiring.

3 ¼" TRS OUTPUT jack: is TRS (tip-ring-sleeve) ¼" balanced jack is compatible with either balanced or unbalanced systems.

For balanced systems, use a microphone cable wired with pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is

signal return (negative). Refer to the RaneNote, “Sound System Interconnection” for unbalanced wiring.

4 XLR OUTPUT jack: is balanced output is wired per AES standards of pin 2 “hot”, as described above in 1.

5 Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. is mates with an IEC 60320 C5 line cord (USA

domestic). Do not lift the ground connection!

ME30S Connection

INPUTS

Both XLR 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-os. e 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

e 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. e signal exists dierentially 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 nor-

mally uses the ¼" jacks. ree parallel Input connectors allows

driving a second signal processor or amplier 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 ME30S,

these require an external mic preamp.

Operating Instructions

Insuring the proper level of gain though the ME30S is just as

important as adjusting the equalizer bands. Improper gain dis-

tribution is a common cause of loss of system headroom and less

than optimum noise performance.

e OVERLOAD LED informs of an imminent or passed

overload to the equalizer. Occasional blinking of the OL with

program source material is ne, indicating optimized signal-

to-noise performance of the ME30S. Run the ME30S with an

input signal that is as hot as possible without the OL lighting

more than occasionally.

e BYPASS switch allows comparison of equalized versus

un-equalized signal. It is also useful in adjusting the level of the

ME30S for unity gain and best signal-to-noise performance. e

gain of the ME30S is optimized when there is no sound level dif-

ference between the bypassed and the active positions.

e overall gain range of the level control for the ME30S

is o to +6 dB for unbalanced operation, or o to +12 dB for

balanced operation. e level dierence between the equalizer in

bypass or active can be signicant. Adjust the LEVEL control so

the signal level is the same between the bypassed and active posi-

tions of the BYPASS switch.

GETTING STARTED

Here is one method of setting your equalizer that works well.

Begin with the following settings:

1. Engage the BY PASS switch. (switch depressed, BYPASS LED

on.)

2. Put all sliders in their center position (0 dB). e center posi-

tion has a grounded detent.

3. Position the LEVEL control about “6” for unbalanced opera-

tion and “7” for balanced operation.

4. Apply a signal to the system.

5. Verify the OL LED is not on—occasionally blinking during

extreme peaks indicates an optimal setting. But if it lights up

a lot or lights steadily, lower the output level of the previous

device in the signal chain.

6. Release the BYPASS switch and begin adjusting the equalizer

lters.

7. During lter band adjustments, if the OL LED lights more

than occasionally, turn down the output of the previous de-

vice in the signal chain.

8. Once all lter bands are adjusted to your liking, compare the

signal loudness with the equalizer bypassed and active. Adjust

the LEVEL control on the ME30S so there is no dierence

between the levels of bypassed versus active.

9. e last step is to reconrm that the OL LED lights only

when there are large signal spikes in the program material, as

in step 5 above.

For insight into how to use an equalizer, to alleviate acoustic

problems or to adjust the overall tone of the program material,

please read the following two sections.

ACOUSTIC COMPENSATION

A graphic equalizer may be used to correct many acoustic

problems. However, one should fully understand the ramica-

tions of doing so. Acoustic problems are generally not consistent

across the entire area of sound coverage. is is much more of a

problem when setting up a sound system for large venues. In a

typical large room or hall, there will be areas that have acoustic

reinforcement problems and other areas where certain frequen-

cies are almost entirely canceled out. Try to seek an acoustic

remedy for acoustic problems whenever possible. When this is

not possible or feasible, an equalizer may be used to compensate

for an acoustic problem. But the problem is only improved at

the point where the measurement is taken, other locations in the

room may be adversely aected by the equalizer setting. For this

reason, measure the acoustic response of the system from several

locations and average the equalizer’s setting. Doing this helps

most locations in the venue to have an equal sound quality.

e best way to “see” what the acoustic signature of the room

is doing to sound is to use a real time analyzer or any of the

many computerized measurement systems. Using these devices

to analyze the response of the room and the sound system is the

only accurate means available for setting an equalizer properly.

Equalization can be like spice in the hands of a master chef.

A little goes a long way in improving sound quality, too much

and the mix is spoiled. If modest amounts of equalization (6-8

dB) do not solve the problem, it is best remedied by other means.

Avoid adding large amounts of boost below 63 Hz, especially

when using vented bass cabinets. Boosting frequencies below

the vented enclosure’s low frequency cuto can easily cause over

excursion of the speaker’s cone, causing premature failure. In ad-

dition, boosting low frequencies can make your power amplier

run hotter, leading to premature amplier failure.

When equalizer adjustment is completed, compare the un-

equalized sound with the equalized sound by alternately engag-

ing the BYPASS switch. Use familiar source material and walk

around in the sound coverage area to insure that no anomalies

have been introduced into the sound system. If it sounds good,

you’re done.

TONE CONTOURING

If a ME30S is used for tone contouring by ear, be careful about

adding upper bass (63 Hz to 200 Hz) as this can cause “muddi-

ness” or loss of denition. (Also see the previous warning about

boosting frequencies below 63 Hz.) Middle frequency problems

usually express themselves by vocals having a nasal quality (too

much mid band boost) or vocals not being easily understandable

(usually caused by mid band frequencies being under represented

in the overall sound). High band problems show as “sizzle”—

not good, and is sometimes caused by too much high frequency

boosting. is is most obvious with cymbals and hi-hats. To

use the cooking metaphor, high frequencies should simmer, not

sizzle.
