INTRODUCTION
Thank you for your time and interest in the EVE Audio product range.
EVE Audio is a loudspeaker manufacturer based in Berlin, Germany, that
specializes in the development and design of unique studio monitors.
The use of first-class components is our highest priority because we firmly
believe this is the only way to manufacture first-class products.
You have chosen the SC4070 studio monitor, a loudspeaker from our Silvertone
SC series conceived as a four-way system.
An additional mid-range driver guarantees an excellent definition in the mid
frequencies, which raises the four-way system to a completely different
listening level. The two woofers reproduce the exact same frequency range,
while the mid-range driver and tweeter cover consecutive ranges. Due to this
design, the SC4070 is symmetrically mirrored.
In a horizontal arrangement, the SC4070 is ideal as a fully symmetrical central loudspeaker. The SC4070 features EVE Audio‘s Air Motion Transformer taken from the RS series. The mid-range driver and the two woofers sport a high-quality chassis developed by EVE Audio. The lot is completed by the implementation of high-resolution DSP technology plus powerful and efficient amplifiers.
We wish you a lot of fun with your EVE Audio monitors. If you have any
questions regarding our products, do not hesitate to contact your nearest
dealer or get directly in touch with us… We will be more than happy to help
you out!
All the best from Berlin.

QUICKSTART
If you already have experience with studio monitors, the QuickStart guide
ought to be more than enough to get you started.
For inexperienced users we recommend reading the whole user‘s manual in order
to prevent any misuse.
First Steps
Check the package components (loudspeaker, user‘s manual, power cord, grille,
rubber feet).
Check the voltage setting (see „Mains Voltage Selector“).
Check the setting of the DIP Switches (variable).
Speaker Connection
Connect one of the monitor inputs on the rear side (RCA or XLR) to the line
output of a playback source, for instance, an audio interface. The output
level should be as low as possible.
Powering On
Engage the Power switch on the rear side of the loudspeaker to turn it on or
off.
The LEDs around the Volume control on the front panel will light up clockwise.
If the LED on the right end is dimly lit, this indicates that the loudspeaker
is in Standby mode. Press the Volume control to turn the loudspeaker on. If
you turn the Volume control counterclockwise until the LED on the left end
lights up dimly the loudspeaker will be muted.
Increase the output level on the source device until the LED ring starts to blink, then reduce the output level a bit. The maximum operating level for the input (i.e. the analog to digital converter) is now set optimally. To set the desired listening volume use the Volume control on the loudspeaker. The LED ring indicates the volume setting. If the LED ring starts to blink, reduce the output level on the signal source.
OPERATION
Check the package components (loudspeaker, user‘s manual, power cord, grille,
rubber feet);
Check the voltage setting (see „Mains Voltage Selector“).
Check the setting of the DIP Switches (variable).
Connections: there are two input connectors on the rear side. These allow the
connection of balanced sources with XLR connectors or unbalanced
sources with RCA connectors.
- Pin assignment XLR: 1 = Shield, 2 = hot (+), 3 = cold(-).
- Pin assignment RCA: Center conductor = Signal, Ring = Shield.
Both analog inputs can be used simultaneously, whereby the signals are summed.
Depending on the setting of the Max. Input DIP switch on the rear panel, the
maximum level of the source signal should not exceed +7 dBu or +22
dBu (see Max. Input). If the input is overloaded the LED ring will start
blinking.
Horizontal/Vertical Orientation
The SC4070 can be used in horizontal or vertical positions thanks to the incorporated swiveling „Mid/High Silver Plate.“ By default, your monitor is adjusted to be placed horizontally. To use it in a vertical position, turn the tweeter/mid-driver section 90º so that the sound transducer is vertically oriented. Your dealer will be happy to do this for you. If you would like to do it by yourself after the monitors have been installed, follow these steps:
-
Remove the four screws of the mid/high plate.
-
Turn the whole tweeter/mid-driver section 90º. The direction does not really matter. Hold the tweeter/mid-driver section by the screws when
handling it. -
Fasten the tweeter/mid-driver section again with the screws. Tighten the screws only a bit tighter than you would by hand.
The whole procedure ought to be carried out with utmost care in order not to
damage the surface of the speaker.
To avoid damages due to metal parts ending up inside the Twitter, we recommend
you to place the protection grille immediately after any modification.
The Grid
In order to protect the tweeter, your EVE Audio monitors are supplied with a
metal grid, which has no impact on the sound. The grid is attached to the
tweeter by means of magnetic attraction. Be careful not to damage the folded
tweeter diaphragm when placing the grid:
Hold the grille with your fingers parallel to the front side of the monitor. The perforated hexagon must exhibit two horizontal sides. Make sure that the rille remains parallel to the front side. Draw the grille close to the tweeter. The tweeter‘s magnetic field will attract and fix the grille, which can always be adjusted later if needed.
Operating Modes
Standby mode | Volume mode (-10 dB) | Settings menu (Low Filter @ -2 dB)
Powering on/off: Standby Mode
Press and hold the control three seconds in order to put the monitor in
Standby mode. The volume will decrease gradually while the LED ring lights up
once around the Volume control. Afterward, the LED on the right end will
remain dimly lit and the power consumption is reduced to 1 watt. To exit the
Standby mode press briefly the Volume control once again. The
the level will increase gradually.
Volume Mode
Level Adjustment
The maximum input level for balanced (XLR) and unbalanced signals (RCA) is +7
dBu or +22 dBu, depending on the position of the Max. Input switch on the rear
panel (see DIP Switches). Higher levels produce distortion due to the
overloading of the analog to digital converter. Given that some professional
studio devices can produce in excess of +22 dBu, the LED ring will start
blinking whenever the AD converter is overloading. If that is the case, the
output level of the source should be reduced.
Volume Adjustment
Turn the knob to adjust the volume. Depending on the LED mode selected (see LED mode), the volume will be displayed as a dim/bright circle or as a dim/bright point.
The control’s response curve is not linear. The increments become finer as the volume increases:
| -80 dB (minimum) to -48 dB:c | 2 dB |
|---|---|
| -48 dB to -20 dB: | 1 dB |
| -20 dB to 0 dB (maximum): | 0.5 dB |
Mute
To mute the monitor, turn the Volume control counterclockwise until you reach
the minimum level. When the LED on the left end lights up dimly the Mute mode
is activated. To exit the Mute mode simply turn the control clockwise until
you reach the desired volume.
Settings Menu
Press the control once to enter the Settings menu. Here you can set three
different filters (Low, Desk, High), as well as the LED ring‘s behavior. The
LED of the currently active function will blink.
Turn the control to choose the filter or LED mode desired. The blinking LED
indicates the function selected, while the steady-on LED indicates the value
assigned to that function.
Press the control to confirm your selection. The blinking will stop once the
selection is confirmed.
Turn the control to adjust the filter or the LED behavior. When you are
satisfied with the setting, press the control again to go back to the Settings
menu. You can then select and edit another function. To exit the Settings menu
press and hold the control for three seconds or simply wait 10 seconds. The
loudspeaker will then return automatically to the Volume mode.
Filters
The filters of the EVE Audio monitors were specially developed to offer you
the possibility of adjusting your monitoring system to the characteristics of
your room. These filters help correct the alterations to the frequency
response produced by the room acoustics and listening distance. Do bear in
mind that correcting bad room acoustics with filters will only achieve average
results. In any case, you should try to use the filters as little as possible.
Low Filter
The Low-Shelf Filter allows you to boost or attenuate frequencies below 300 Hz
in 0.5 dB steps. Use this filter whenever the acoustics of your room cause
problems in the low-frequency range.
If the low frequencies are boosted by the room, you can attenuate them with
the Low-Shelf Filter. The reasons for this boost could be the room modes or
the loudspeakers being too close to the walls. In the same way, if the low
frequencies are too weak, you can boost them to balance the
frequency response.
High Filter
The High-Shelf Filter allows you to boost or attenuate frequencies above 3 kHz in 0.5 dB steps. High frequencies are affected depending on the distance from the sound source to the listening position. The further you are from the loudspeakers, the weaker the high frequencies. In such cases the filter should be set to boost them. In desktop applications, distances can be as short as 1 m (3 ft), which results in the high frequencies being boosted. To compensate for this effect you should use the High-Shelf Filter to attenuate the high frequencies.
If you have a very dead room, it might be wise to boost the high frequencies in order to have a more balanced overall sound. When the listening position
is too close to the loudspeakers or the room has reflective surfaces, it is reasonable to attenuate the high frequencies.
Mid Filter
The Mid Filter is a bell filter with a 1 kHz center frequency. It allows you
to boost or cut the mid-range up to +/-3 dB in 0.5 dB steps.
This frequency range is very important for the balance between lower mid and
higher mid frequencies. Use the Mid filter to adjust the balance between
fundamental and harmonic frequencies in the music material. Depending on the
acoustics of your room, some of the sound energy produced by the monitors may
be reflected by surfaces like walls, floor, and/or ceiling in the room, thus
altering the perceived sound.
Desk Filter
The Desk Filter has two functions. When turned down it acts as a narrowband EQ set to 160 Hz. The reflections of mixers and similar surfaces usually result in the boosting of low mids. With the Desk Filter, you can lessen this effect by turning down the filter gain. When turned up, the Desk Filter also works as an EQ but this time set to 80 Hz. This allows you to give more punch to the lower frequencies.
The following applies to the Low, High and Desk filters :
- Every step represents a 0.5 dB increment.
- The maximal boost is +3 dB and the maximal attenuation is –5 dB.
- Refer to the chapter on POSITIONING to set the filters of your EVE Audio monitors effectively.
LED Mode
The LED mode determines in which of the four available fashions the LED ring
displays the volume level. The LEDs represent given levels, which are
displayed and adjusted according to four steps. Intermediate steps are
indicated by the brightness between two adjacent LEDs.
Bright Ring
All LEDs up to the selected volume level light up brightly. The louder the
signal, the longer the brightly lit-up ring.
Bright Point
Only the LEDs corresponding to the selected volume level light up brightly.
The louder the signal, the further up the brightly lit-up point moves.
Dimly Lit Ring
All LEDs up to the selected volume level light up dimly. The louder the
signal, the longer the dimly lit-up ring. In this mode, the LEDs light up
brightly momentarily while you adjust the volume level.
Dimly Lit Point
Only the LEDs corresponding to the selected volume level light up dimly. The
louder the signal, the further up the dimly lit-up point moves. Intermediate
steps are indicated by the lighting of two adjacent LEDs. The level ranges
from -60 dB to +10 dB, taking „0 dB“ as a reference point.
Saving Your Settings All settings on the front and rear panels are
automatically saved. The loudspeakers can be disconnected anytime without the
settings being lost.
Power Switch
The power switch on the rear panel disconnects the loudspeaker completely from
the power grid. When powered off all settings are saved and the power
consumption is reduced to 0 watts. After powering on again, the loudspeaker
will return to the state it was in before being turned off (Standby mode, Mute
mode, or a given volume level). Even if powered off via a multiple outlet
power strip, the monitor will return to the state it was in before being
turned off.
In order to prevent switching noise with your monitoring system, keep in mind
the following rules: Power all audio sources on first and your loudspeakers
last. When turning off your system, power off your loudspeakers first and then
all audio sources.
DIP Switches
On the rear panel of your EVE Audio monitors, you will find three DIP
Switches. These allow you to secure your loudspeaker settings to prevent them
from being changed inadvertently.
Volume
When set to “lock,” this DIP Switch secures the current volume setting. The
LED ring on the front panel indicates the volume setting, but it cannot be
modified. When set to “variable,” the volume setting can be changed by simply
turning the knob.
Filter
When set to “lock,” this DIP Switch secures the current filter settings. The
filter settings can be read on the LED ring, but they cannot be modified. When
set to “variable,” the filters can be modified freely.
Not used
No Function.
Max. Input
This DIP Switch determines the input sensitivity of the SC4070. In a studio
environment, the reference level (0dB) ought to be 4dBu. In such environments,
leave the setting at “+7dBu.” However, some studio gear allow much higher
output levels. If it were impossible to reduce the output level of such
devices, set the switch to “+22dBu.” The “+7dBu” setting ought to be suitable
for most situations.
Mains Voltage Selector
The Mains Voltage Selector allows you to adjust the operating voltage of your
EVE Audio monitors to the local power grid. Set it to “230” if your local
power grid is 220-240 volts or “115” if it is 110-120 volts. If you change the
mains voltage value you also have to replace the fuse of the IEC connector
with an appropriate one. The corresponding fuse values are printed on the unit
underneath the IEC connector.
Power Connector (IEC)
Use the power cord supplied to connect your EVE Audio monitors to the power
grid. The IEC connector includes an integrated fuse. If your EVE Audio
monitors stop working and the fuse seems to be the problem, proceed as
follows:
- Turn the loudspeaker off.
- Disconnect it from the power grid.
- Detach the IEC connector from the unit.
- Remove the fuse.
- Change the fuse. The replacement fuse should comply with the values stated on the subwoofer.
POSITIONING
Speaker Positioning + Rubber Feet
Ideally, there should be no objects or obstacles between the loudspeakers and
the listening position. Furthermore, asymmetrical positioning is important.
This applies to the distance between speakers as well as to the walls,
ceiling, and floor. In order to have a symmetrical stereo image, it is also
important to have symmetrical reflections. We recommend keeping a distance of
at least 0.5 m (19 inches) to the walls, in order to avoid low
frequency boosting.
EVE Audio monitors can also be flush-mounted in a wall, in which case there
should be enough airflow. This is important to keep the electronic components
cool but also to allow for the best performance of the bass reflex ports. We
recommend keeping at least 3 cm (1 in) to the sides and
top.
The SC4070 monitor was designed to be placed vertically or horizontally. The
best position in each case will be determined by the room and the system used.
By default, your monitor is adjusted to be placed horizontally. To use it in a
vertical position, turn the tweeter/mid-driver section 90º. Follow the
procedure indicated in the “Horizontal/Vertical Orientation” section. Finally,
fix the supplied rubber feet to the bottom side of the monitor and place it on
an even and stable surface.
Rubber feet: your EVE Audio monitors are supplied with four self-adhesive
rubber feet. Fix them to the bottom of your loudspeakers to place the
monitors safely on an even surface. Furthermore, the rubber feet improve the
acoustic decoupling of the loudspeakers from the surface.
Height and Distance
The tweeter of your EVE Audio monitors should be ideally placed at the same
height as your ears. If this is not possible tilt the monitors so that the
tweeter is directed to your ears. The ideal distance between the monitors and
the listening position is 2-3 m (7-10 ft).
These values are only meant as a reference and depend a lot on the characteristics of the room. In live rooms, you will be forced to reduce the distance, while in dead rooms the distance to the loudspeakers can be larger.
Stereo Setup
The so-called “stereo triangle” is the best way to place speakers in a stereo
setup, i.e. the monitors and the listening position should form an equilateral
triangle. Try the following: Establish the ideal distance to the listening
position (see “Height & Distance”). Place the monitors in such a way that the
distance from each other and to the listening position is the same. Turn both
monitors so that their front panels are pointed towards the listening position
(all angles of the stereo triangle should be 60º).
Stereo Setup + Subwoofer (2.1)
In such a setup, the subwoofer is fed by the stereo signal source. The
subwoofer filters the low-frequency components of the stereo channels and sums
them to produce a mono signal, which it then reproduces. The high frequencies
are forwarded to the full-range satellite speakers.
Ideally, such a system would comprise two EVE Audio SC4070 monitors plus an
EVE Audio TS110 or TS112 subwoofer. These subwoofers allow you to set the
crossover frequency for the satellite loudspeakers and the subwoofer.
The positioning of the two satellites should be done in the same manner as in
a stereo setup (see “Stereo Setup”).
The subwoofer should be placed on the ground between both satellites.
Considering that low frequencies are omnidirectional, the subwoofer does not
have to be centered exactly between the two satellites. The subwoofer can be
moved back a bit so that it is at the same distance from the listening
position as the satellites. This guarantees all transducers are aligned in
time.
Multichannel Setup (5.1)
The most common 5.1 systems consist of three front channels (left, right and
center), two surround channels (left/right) and a subwoofer for the low
frequencies. The speakers from a circle around the listening position.
Ideally, a 5.1 system would comprise five EVE Audio SC4070 monitors plus an
EVE Audio TS110 or TS112 subwoofer. However, you might also want to consider
the following combinations: Front: SC4070, Center: SC4070, Rear: SC307. The
positioning of the two front speakers and the subwoofer should be done in the
same manner as in a stereo setup with a subwoofer (see “Stereo Setup +
Subwoofer“). Place the center monitor directly in front of the listening
position, i.e. right in the center between both front satellites.
The rear satellites should form an isosceles triangle with the listening position forming an angle of 140º. Verify that all speakers are at the same distance from the listening position so that they are aligned in time.
Mixer/Workplace Reflections
Regardless of whether the monitors are to be used in a recording studio with a
mixing desk and meter bridge or in a desktop environment, hard surfaces can
produce annoying reflections that alter the natural reproduction of the
loudspeakers. Especially in the low-mid frequency range.
If this is the case with your setup, use the Desk Filter of your EVE Audio monitors to reduce the impact of the reflections from the desk or mixer.
Room Acoustics
In order for the described measures to work effectively, we recommend that you
put special attention to the room acoustics. The size, contents, wall
parallelism, proportion, and reflective behavior of the room, as well as the
corners, the building materials and their characteristics, play a very
important role in the acoustics of a room.
Room acoustics is a science in itself and it is unfortunately out of the scope
of this manual. However, we have put together a short bibliography for you:
