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 StepsCheck 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 ConnectionConnect 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 OnEngage 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 unbalancedsources 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 +22dBu (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 whenhandling 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 GridIn 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 ModePress 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. Thethe level will increase gradually.

Volume ModeLevel AdjustmentThe 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

MuteTo 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 MenuPress 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.FiltersThe 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 thefrequency 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 ModeThe 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 RingAll LEDs up to the selected volume level light up brightly. The louder the signal, the longer the brightly lit-up ring.Bright PointOnly 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 RingAll 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 PointOnly 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 SwitchThe 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 SwitchesOn 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.VolumeWhen 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.FilterWhen 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 usedNo Function.Max. InputThis 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 SelectorThe 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 FeetIdeally, 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 lowfrequency 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 andtop.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 themonitors safely on an even surface. Furthermore, the rubber feet improve the acoustic decoupling of the loudspeakers from the surface.

Height and DistanceThe 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 SetupThe 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 ReflectionsRegardless 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 AcousticsIn 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:
