Q™SERIES EQUALIZERS

Thank you for purchasing a Peavey Electronics Q Series graphic equalizer. The Q family features

two dual-channel models and one single-channel unit, all incorporating Peavey’s legendary low-

noise, low-distortion design. Ruggedly constructed, Q Series EQs have 45 mm, center-detented

control sliders enclosed in metal for durability. These two rack-space units also offer ±15 dB gain

control and an LED display indicating output level. Other shared features include switchable low-cut

filters, +21 dBu balanced inputs and outputs, and bypass switches. Q Series equalizer filters are set

at ISO center frequencies within 3% accuracy. Whether on stage, in the studio, or simply tweaking

your home hi-fi system, the Q Series has an EQ for you.

ENGLISH

EQUALIZATION PROCESS

Always begin the equalization process with all sliders at their center-detent (flat response) positions.

For units equipped with FLS®, increase system volume until slight feedback occurs. Note the LED(s)

that illuminate, and lower the corresponding fader(s) until feedback is eliminated. In other words, see

the light pull down the fader. For the Q 215B, lower each fader until the feedback frequency is

found. Lower the faders in small amounts to avoid adversely affecting sound quality. Likewise,

excessive boosting of a frequency may result in feedback.

EXERCISE CAUTION WHEN ATTEMPTING TO BOOST FREQUENCIES BELOW SPEAKER

SYSTEM TRANSDUCER CUT-OFF.

Typical sound reinforcement enclosures are not designed for 20 Hz performance, and transducer

damage could result from “over-boosting” low frequencies. Excessive boost at very low frequencies

could also limit overall system headroom. Engaging the 40 Hz low-cut filter is the best way to avoid

these problems.

NOTE: Superb tonality, absence of feedback, and great-sounding systems may not be possible with

any graphic equalizer. All other system components must be of high quality and designed for the

application. No amount of equalization will correct an acoustically bad room, bad

microphone/speaker arrangement, or completely correct the response curve of a poor loudspeaker.

FEATURES AND CONTROLS

FRONT PANEL

(1) OUTPUT LEVEL LED METER

This LED array indicates output level from –12 dB to +12 dB.

(2) GAIN

This calibrated, detented control regulates overall gain of the EQUALIZER SECTION (3).

Unity gain throughout the signal chain can be maintained by recovering lost signal gain at this

point. The equalization process may result in noticeable signal loss. To compensate for this

loss, engage the BYPASS (5) switch and compare the signal level with that of the equalized

level. Increase the GAIN control until the equalized level approximates that of the bypassed

level. Let your ears be your guide.

(3) EQUALIZER SECTION

These calibrated, detented controls adjust the amount of cut or boost at their respective

frequencies. They are adjustable from 18 dB cut to 12 dB boost (15 dB cut to 15 dB boost on

the 215B). For units equipped with FLS, the LED at the top of each band will illuminate as an

indication of feedback at that frequency.

(4) LOW-CUT FILTER

This switch activates the low-cut filter that rejects frequencies below 40 Hz. Frequency roll off

is 18 dB per octave with the switch engaged. This filter will operate even with the BYPASS (5)

switch engaged. The adjacent red LED indicates activation.

(5) BYPASS

This switch allows the signal to bypass the unit with the exception of the LOW-CUT FILTER

(4). When this switch is engaged, the signal is routed from INPUT (10 and 11) though the

low-cut filter to output (8 and 9).

(6) POWER

This 2-position rocker switch applies mains power to the unit when in the ON position. The

adjacent green LED indicates mains power activation.

REAR PANEL

(7) IEC MAINS CONNECTOR

This is a standard IEC power connector. An AC mains cord having the appropriate AC plug

and ratings for the intended operating voltage is included in the carton.

Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used

does not have a ground pin, a suitable grounding adapter should be used and the third wire should

be grounded properly. To prevent the risk of shock or fire hazard, always be sure that the equalizer

and all associated equipment is properly grounded.

NOTE: FOR UK ONLY

If the colors of the wires in the mains lead of this unit do not correspond with the colored markings

identifying the terminals in your plug, proceed as follows: (1) The wire that is colored green and

yellow must be connected to the terminal that is marked by the letter E, the earth symbol, colored

green, or colored green and yellow. (2) The wire that is colored blue must be connected to the

terminal that is marked with the letter N or the color black. (3) The wire that is colored brown must

be connected to the terminal that lis marked with the letter L or the color red.

(8) TRS BALANCED OUTPUT

These 1/4" Tip/Ring/Sleeve (stereo) jacks provide balanced output when used with TRS

connectors and 2-conductor shielded cables. When used with a mono 1/4" (TS) phone plug,

the output is unbalanced.

(9) XLR OUTPUT

These male 3-pin connectors provide balanced output when used with female XLR

connectors.

(10) TRS BALANCED INPUT

These1/4" Tip/Ring/Sleeve (stereo) jacks provide balanced input when used with TRS

connectors and 2-conductor shielded cables. When used with mono 1/4" (TS) phone plugs,

the input is unbalanced.

(11) XLR INPUT

These female 3-pin connectors provide balanced input when used with male XLR connectors.

PROCESO DE ECUALIZACIÓN

Siempre comienza el proceso de ecualización con todos los sliders en su posición central

(respuesta plana). Para unidades equipadas con el sistema FLS®, incrementa el volumen del

sistema hasta que ocurra la retroalimentación. Nota que el LED(s) que se ilumina y recorta el

slider(s) correspondiente a esa frecuencia hasta que desaparezca la retroalimentación. En otras

palabras puedes ver la luz para bajar el slider. Para el Q 215B, baja cada slider hasta que la

frecuencia de retroalimentación sea encontrada. Baja los sliders con movimientos pequeños para

evitar cambios drásticos en la calidad del sonido. Así mismo, los aumentos excesivos de

frecuencias pueden resultar en retroalimentación.

HAY QUE TENER CUIDADO CUANDO SE TRATE DE INCREMENTAR FRECUENCIAS POR

DEBAJO DEL PUNTO DE RECORTE DE LOS TRANSDUCTORES DE LOS SISTEMAS

Las bocinas típicas de reproducción de música no están diseñadas para frecuencias de 20 Hz, y los

transductores pueden ser dañados por sobrecargas en frecuencias graves. Los incrementos

excesivos en frecuencias muy graves también pueden limitar el umbral del sistema entero.

Encender el filtro de graves de 40 Hz es la mejor manera de evitar estos problemas.

NOTA: Conseguir tonalidad superior, ausencia de retroalimentación y calidad de sonido pueden no

siempre ser posibles con cualquier ecualizador gráfico. Todos los demás elementos deben ser de

alta calidad y diseñados para la aplicación. Ninguna cantidad de ecualización puede corregir un

cuarto con mala acústica, mal posicionamiento de micrófonos/ bocinas, o completamente corregir o

cambiar la curva de frecuencias de una bocina mala.
