Front Panel
1. Power Switch/Clip Light- This bar turns blue when the M1Active 520/620 is powered up (the power switch is found on the top of the speaker) and the bar turns red when the speaker is being overloaded.
2. Acoustic Waveguide- Besides giving the speaker its devilishly good looks, our distinctive silver acoustical waveguide helps spread the tweeter’s high frequency sound evenly across your control room.
3. Tweeter- Our silk dome tweeter is designed to handle all frequencies above 3 kHz. This driver was carefully selected because of its ability to match the woofer and provide crystal clear sound without ear-fatiguing harshness.
4. Woofer- The ultra-light, super-stiff material found in our woofer cone helps the M1Active 520/620 deliver punchy bass and solid midrange (even at loud levels) without distortion.
5
Back Panel
1. TRS Input – This ¼” input accepts balanced “TRS” or unbalanced “TS” cables from your mixer, computer, or any other line level source. Both types of cabling will work, but we recommend balanced TRS (or XLR) cables since they give you better performance and lower noise (especially if you’re using longer cables).
2. XLR Input – This jack functions exactly the same way as the TRS input (see above), but it uses balanced XLR cabling.
3. Gain – This knob sets the input gain of the speaker. Use this knob to set a comfortable loudness level for monitoring.
4. Rear Port – The rear port augments the bass generated by the woofer to increase the low frequency SPL over that of non-ported speakers.
Make sure this hole is not obstructed
since this will adversely affect bass response.
5.Acoustic Space Switch – This switch compensates for placement near walls and corners. Please see section titled “About the Acoustic Space Switch” for more on these settings.
6.Hi Boost – This switch allows you to tailor the speaker’s high frequency response to your control room. Please see the section “About the Hi-Boost Switch” for more about these settings.
Both XLR and TRS connectors have been provided for your convenience, but please use only one connection at a time to avoid overloading the inputs.
7. Mid Boost – This 2-position switch provides a 2.5 dB wide-band boost in the midrange at 1.8kHz. This has the effect of moving the soundstage “forward” closer to the mix position. Some engineers prefer to have this boost if the speakers are positioned farther than a few feet away. We recommend you try either the boosted “+” or bypassed “0” settings for a few mixes and select whichever one makes your mixes translate better.
6
8. Lo – This high-pass filter switch lets you pick the point at which the speaker will roll off low frequencies. Many subwoofers roll off frequencies above 80 Hz, so if you want to use your M1Active 520/620 speakers with a subwoofer, set this switch to “80.” If you do not have a subwoofer, leave this set to the lowest number to let the M1Active 520/620 play its full range of sound.
Alternatively, you may want to hear how your mix will translate on smaller speakers (such as a TV, or radio). Set this switch to 80Hz or 100Hz (if you have a subwoofer, turn it off) and you’ll get a sense of how your mix will sound on smaller speakers with reduced bass output.
9.AC Voltage Selector – This 2-position switch sets the AC input voltage for the speaker. US users should set this switch to “100-120V” whereas UK and most European users will need to set this to “220-240V.”
10.AC Input – This jack accepts standard 3-prong IEC power cables. Make sure your AC Voltage Selector (see item #9 above) is set to the correct voltage for your country.

About the Acoustic Space Switch
The bass response of a speaker is greatly affected by the speaker’s proximity to walls. You’ll notice a buildup in bass frequencies as a speaker moves closer to a wall and even more buildup as the speaker moves closer to a corner. This happens because low frequencies radiate in all directions from the speaker cabinet and are reflected off your walls back into your control room. When this happens, the reflected sound mixes with the direct sound of the speaker itself resulting in “reinforced” bass.
Unlike bass frequencies, midrange and high frequency sounds are much more “directional” and only radiate forward. Because of this, the Acoustic Space Switch only deals with bass frequencies—there is no need for high frequency compensation near walls.
We know that most home and project studios are set up under less than ideal conditions, so we’ve added the Acoustic Space Switch to help you optimize your speakers to your room.
If your speakers are farther than about 3 feet away from the walls of your studio, leave this switch set to the default “0” setting. This “full space” setting outputs bass normally.
If the speaker is up against a wall, set the Acoustic Space Switch to “2.” This setting is known as “half-space” and compensates for boosted bass due to your speakers being placed near one wall.
Finally, if your speaker is positioned in a corner, set this switch to “4.” This is known as a “quarter-space” setting and compensates for placement next to two walls.
8
About the Hi-Boost Switch
This switch engages a 2dB shelving filter starting at 3 kHz that will boost when set to “+”, cut when set to “-”, and will be bypassed when set to “0.”
If your mixing environment has many acoustically reflective surfaces and sounds overly “bright,” you can compensate for this by reducing the high frequency output of the M1Active 520/620. Conversely, if you are mixing in an acoustically “dead” room with lots of sound absorption and little reflection, you can boost the high frequency output.
If you’re not sure about your control room, leave this setting to “0,” mix a few songs, and play those songs in different environments (i.e., your living room, car, boombox, etc.) Your mixes should fall into one of the following three categories:
1.) Too bright: If your mixes have too much high frequency content and consistently sound too bright, then set Hi-Boost to “+” because your control room is acoustically “dead.”
2.) Too dull: If your mixes consistently lack high frequency “sparkle” and sound “dull” it means your control room is too acoustically reflective and that you should set your Hi Boost switch to “-.”
3.) Just right! If your mixes translate well, then leave this switch set to “0” since your control room is well balanced and you don’t need any high frequency compensation from the speaker.

Speaker Placement
The placement of your speakers has a huge impact on how well they will perform in your studio.
Although nearfield studio monitors (such as these M1Active 520/620s) are designed to be more forgiving when it comes to placement, you should do your best to make sure they form an equilateral triangle relative to your head. In other words, make sure that each speaker is equally distant from both your head as well as the other speaker. Once each speaker has been placed, rotate the speakers slightly so that the drivers are pointing toward the engineer.
Take a look at the diagram below. Notice that the distance from the engineer’s head to each speaker is the same as the distance between the left and right speakers. Also note that the speakers are turned slightly so that the drivers are facing the engineer.
This is an ideal setup but if it is not practical (or possible) to do this, try to match this setup as closely as possible.
The speakers and listener should be at the three corners of a triangle having equal length sides
Prime Listening Position
10
Speaker Height:
The ideal height for M1Active 520/620 speakers is so that the speaker is parallel to the ground and that the midpoint of the woofer and tweeter is at ear-height.
The diagram below demonstrates the ideal placement height of the speakers relative to the engineer. Notice that the engineer’s ears are directly between the woofer and tweeter.
Woofer/tweeter midpoint
If possible, use speaker stands and move the monitors off of your desk (or meter bridge, if you are using a mixer). This usually results in better imaging since the monitor is decoupled from your desk and there is less chance reflected sound from the desk (or mixer) reaching your ears and smearing the imaging of your studio monitors.
11
Speaker Orientation:
The M1Active 520/620 has been designed for maximum flexibility when it comes to speaker orientation (i.e., whether the speaker is upright or laying down on its side). For best performance, place the speakers vertically with the tweeter on top. If this is not practical in your control room, go ahead and lay each speaker on its side, but make sure the tweeters are on the “inside” and are closer to the engineer. This will give you the best possible soundstaging for this orientation. Avoid having the tweeter on the “outside” since the added distance between the tweeters may result in a “gap” in the middle of your soundstage.
Ideal Orientation
Acceptable Orientation (tweeters on the inside)
Poor Orientation (tweeters on the outside)
12
Hookup Diagrams
The following two hookup diagrams should give you an idea of how your M1Active speakers can fit into your recording rig.
If you are using a mixer in your studio, your setup will probably be similar to the one below. All audio is routed through the mixer into your M1Active monitors. If you wish to record the output of your mixer, you can take the output of the mixer and send it back to your computer (the diagram below is configured this way). The M1Active has both XLR and ¼” TRS inputs on the back for maximum flexibility, but remember to use only one input at a time.
13
For a more portable recording setup without a mixer, you may want to use a portable USB or Firewire interface. The diagram below illustrates how a portable setup might look. The interface to the computer via USB and sends audio out to the speakers through ¼” or XLR cables. Remember that the M1Active will accept both balanced and unbalanced signals, but we recommend balanced cabling for best performance.
Note that the M1Active 520/620 is an “active” loudspeaker with built-in amplifiers for the woofer and tweeter. This means that you do not need any additional amplifiers and that the line-level audio output of your mixer or digital audio workstation should be connected directly to the speaker.
Do not use an external amplifier with the M1Active 520 speaker. The speaker has built-in amplification and using an external amplifier could damage the speaker.

Panel frontal
1. Interruptor de encendido/barra de luces de recorte – Esta barra se pone azul cuando se enciende el M1Active 520/620 (el interruptor de encendido se encuentra en la parte superior del altavoz) y se pone roja cuando se sobrecarga el altavoz.
2. Guía de ondas acústica – Además de brindar al altavoz un aspecto sensacional, nuestra exclusiva guía de ondas acústica plateada ayuda a distribuir el sonido de alta frecuencia del tweeter uniformemente en toda la sala de control.
3. Tweeter – Nuestro tweeter con domo de seda está diseñado para manejar todas las frecuencias superiores a 3 kHz. Este driver fue seleccionado cuidadosamente debido a su capacidad para adaptarse al woofer y brindar un sonido de transparencia cristalina sin la fatiga auditiva de la estridencia.
4. Woofer - El material ultraliviano y súper rígido del cono de nuestro woofer ayuda al M1Active 520/620 a brindar graves más intensos y medios sólidos (aun a altos niveles de sonoridad) sin distorsión.
21
Panel trasero
1. Entrada TRS – Esta entrada de ¼” acepta cables “TRS” balanceados o “TS” desbalanceados de su mezclador, computadora o cualquier otra fuente de nivel de línea. Ambos tipos de cableado funcionan, pero recomendamos los TRS (o XLR) balanceados, puesto que le brindan mejor perfomance y menos ruido (especialmente si usa cables largos).
2. Entrada XLR – Este jack funciona exactamente de la misma manera que la entrada TRS (vea arriba), pero usa cableado XLR balanceado.
3. Ganancia – Esta perilla fija la ganancia de entrada del altavoz. Use esta perilla para fijar un nivel de intensidad sonora cómodo para el monitoreo.
4. Puerto trasero – Este puerto de subfrecuencias aumenta los graves generados por el woofer para incrementar el SPL de baja frecuencia con respecto al de los altavoces sin puerto trasero.
Asegúrese de que el orificio no quede
obstruido, puesto que se afectará perjudicialmente a la respuesta en graves.
5. Conmutador Acoustic Space (acústico espacial)
Este conmutador compensa la ubicación cerca de paredes y esquinas. Para más información sobre esta función, vea la sección “Acerca del conmutador acústico espacial”.
Se proporcionan conectores XLR y TRS para conveniencia del usuario, pero use una sola conexión por vez para evitar sobrecargar las entradas.
6.Hi Boost (Refuerzo de agudos) – Este conmutador permite adaptar la respuesta de alta frecuencia del altavoz a la sala de control. Para más información sobre esta función, vea la sección “Acerca del conmutador de refuerzo de agudos”.
7.Mid Boost (Refuerzo de graves) – Este conmutador de 2 posiciones brinda un refuerzo de toda la banda de 2.5 dB en la gama media a 1.8 kHz. Este refuerzo tiene el efecto de “adelantar” el escenario sonoro y acercarlo a la posición de mezcla. Algunos ingenieros prefieren tener este refuerzo si los altavoces se colocan más alejados que unos pocos pies. Recomendamos que pruebe ya sea el ajuste reforzado “+” o puenteado “0” con unas cuantas mezclas y seleccione la que haga que sus mezclas se trasladen mejor.
22
8. Lo (Bajas frecuencias) – Este filtro pasaaltos permite seleccionar el punto en el que el altavoz produce el corte progresivo de las bajas frecuencias. Muchos subwoofers cortan progresivamente las frecuencias superiores a 80 Hz, de modo que si desea usar sus altavoces M1Active 520/620 con un subwoofer, debe ajustar este conmutador a “80”. Si no tiene subwoofer, déjelo ajustado al número más bajo para permitir que el M1Active 520/620 reproduzca su gama sonora completa.
Como alternativa, puede desear oír cómo se reproduce su mezcla en altavoces más pequeños (como los de televisores o receptores de radio). Ajuste este conmutador a 80 Hz o 100 Hz (si tiene un subwoofer, apáguelo) y obtendrá una sensación de cómo sonará su mezcla en altavoces más pequeños con salida de graves reducida.
9.Selector de tensión de CA – Este conmutador de 2 posiciones fija la tensión de CA de entrada del altavoz. Los usuarios de EE.UU. deben colocar este conmutador en “100-120V”, mientras que los del Reino Unido y la mayoría de los países europeos deben colocarlo en “220-240V”.
10.Entrada de CA – Este jack acepta cables de alimentación IEC de 3 terminales estándar. Asegúrese de que el selector de tensión de CA (vea el punto 9 precedente) esté ajustado a la tensión correcta correspondiente a su país.
