QUICK START

If you already have experience with studio monitors, the Quick Start guide ought to be more than enough to get you started.
For unexperienced users we recommend reading the whole user’s manual in order to prevent any misuse.
2.1. First Steps
Check the package components (loudspeaker, user’s manual, power cord, grid, rubber feet).
Check the voltage setting (see “Mains Voltage Selector”).
Check the setting of the DIP Switches (variable).
2.2. 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.
2.3. 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 counter clockwise 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

3.1. First Steps

Check the package components (loudspeaker, user’s manual, power cord, grid, 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.
The maximum level of the source signal should not exceed 8dBu. If the input is overloaded the LED ring will start blinking.
3.2. Operating Modes

3.3. 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. Afterwards, the LED on the right end will light dimly and the power consumption is reduced to 1 watt.
To exit the Standby Mode press briefly the Volume control once again. The level will increase gradually.
3.4. Volume Mode

• Level adjustment
  The maximum input level for balanced (XLR) and unbalanced signals (RCA) is +7dBu or +22dBu, 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 +22dBu, 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:-80dB (minimum) to -48dB:| 2dB
    ---|---
    -48dB to -20dB:| 1dB
    -20dB to 0dB (maximum):| 0.5dB

• Mute
  To mute the monitor, turn the Volume control counter clockwise 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.

3.5. Settings Menu
Press the control once to enter the Settings menu. Here you can set four different filters (High, Mid, Desk, Low), 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.
3.6. 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.
3.7. Low Filter
The Low-Shelf Filter allows you to boost or attenuate frequencies below 300Hz in 0.5dB 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 to weak, you can boost them to balance the frequency response.
3.8. High Filter

The High-Shelf Filter allows you to boost or attenuate frequencies above 3kHz in 0.5dB 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 1m (3ft), 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.
3.9. Mid Filter

EVE Audio product manual
The Mid Filter is a bell filter with 1kHz center frequency. It allows you to boost or cut the mid range up to +/-3dB in 0.5dB 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.
3.10. Desk Filter

The Desk Filter has two functions. When turned down it acts as a narrowband EQ set to 170Hz.
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 80Hz. 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 0.5dB increment.
• Maximal boost is +3dB and maximal attenuation is -5dB.
• Refer to the chapter on POSITIONING to set the filters of your EVE Audio monitors effectively.

3.11. 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.
SC2070

• 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.

• Dim 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.

• Dim 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 -60dB to +10dB, taking “0 dB” as reference point.
3.12. 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.
3.13. Power Switch
The power switch on the rear panel disconnects the loudspeaker completely from the power grid. When powered off all loudspeaker 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.
3.14. 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.

• Max. Input
  This DIP Switch determines the input sensitivity of the SC2070. 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.

3.15. 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.
3.16. 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 loudspeaker.

POSITIONING

4.1. Speaker Positioning + Rubber Feet
Ideally, there should be no objects or obstacles between the loudspeakers and the listening position. Furthermore, a symmetrical 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 to keep a distance of at least 0.5m (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 air flow. This is important to keep the electronic components cool but also to allow for the best performance of the bass reflex ports. We recommend to keep at least 3cm (1 in) to the sides and top.
The SC2070 monitor was especially designed to be placed vertically. Fix the supplied rubber feet to the bottom side of the monitor and place it on an even and steady surface.
If the room conditions force you to place the SC2070 monitor in horizontal position, make sure that the tweeter is pointing to the outside and that the loudspeakers are angled towards the listening position. In any case, you should also try placing the tweeters pointing to the inside. Regardless of the position, always mind the symmetry (both tweeters should point either to the inside or to the outside)!
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.
4.2. 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 SC2070 and the listening position is 1-2 m (3.4-6.5 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.
4.3. 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).

4.4. 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 SC2070 monitors plus one EVE Audio TS110 or TS112 subwoofer, or even two TS108 subwoofers. All these subwoofers allow you to set the crossover frequency for the satellite speakers 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.
4.5. 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 form a circle around the listening position.

Ideally, a 5.1 system would comprise five EVE Audio SC2070 and a TS110 or TS112 subwoofer. Other combinations are also possible.
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.
4.6. 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.
4.7. 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.
