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.

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.
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.
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.

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.
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.
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
ensation near walls.

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.

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.
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.

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.

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.

(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.

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
Se proporcionan conectores
XLR y TRS para

sobrecargar las entradas.
acústico espacial”.
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.
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.
