Page 3: Genelec Key Technologies
Genelec Key Technologies For over 35 years Genelec has been guided by a single idea – to make perfect active monitors that deliver neutral and accurate sound in every kind of acoustical environment. In our quest to improve all aspects of monitoring quality we continuously develop innovative solutions in driver technologies, electronic circuitry, signal processing, enclosure designs, and materials. -
Page 4: What Is A Monitor
Selecting the correct monitors Genelec recommends monitors based on typical listening distances and sound pressure levels. A matching subwoofer exists for every monitor. Refer to our online selection tools or ask your local dealer or distributor for detailed advice. Here are... -
Page 5: Identifying Your Listening Area
Identifying your listening area Divide your room into three equal-sized areas; front, centre and rear. For music productions place your listening setup in the front area. The angle between the left and right monitors should be 60° degrees. Each monitor should be aimed towards the listening position. - Page 6 Find the left-right symmetry axis of your room. Place the listening setup symmetrically in the left-right direction. 60° For typical two-way systems, the recommended height of the monitor acoustical axis is at the ear level, usually between 1.2 and 1.4 metres from the floor. Placing the monitors higher with a slight tilt will minimise floor reflections.

Page 8: Monitor And Listening Location Placement In A Room
Monitor and listening location placement in a room Sound is reflected by the walls, ceiling and floor. The sound level at the listener increases when reflected sound is in phase with the direct sound. The sound level decreases when the reflected sound is out of phase with the direct sound. If the room surfaces have not been designed to diffract the sound energy, most of the reflected sound energy leaves the reflecting wall in the same angle as it arrived to the wall. -

these frequencies appear to be missing. Moving the listening location can solve the problem. Typically the listening location is moved forward or backward. The most accurate stereo imaging can be achieved when the reflections are similar for the left and the right monitor in a stereo pair. This can be achieved by maintaining the same distance to the nearest side wall and the wall behind the monitor, placing the left and right monitors to the same height in the room, and placing the listening location symmetrically in the room in the left-right direction. - Page 10 Distance > 0.6 m can reduce Maximum the level of these frequencies 0.6 m (Hz) Placement of monitors and subwoofer At low frequencies, it is crucial that the most fundamental room modes are equally excited. Using a single subwoofer, a placement along the front wall, slightly off-centre from the room middle axis could be recommended.
- Page 11 Genelec active 7000 series subwoofers have a crossover filter set to 85 Hz. The subwoofer reproduces the frequencies lower than 85 Hz. Higher frequencies are reproduced by the monitors.
- Page 12 Post-production facility applications In certain applications, such as large post-production studios, subwoofer Screen placement along the front wall is not recommended as this places the subwoofer very far from the listening position, and the subwoofer frequency response will not be flat. In these cases, we recommended locating the subwoofer close to the main monitor setup along the side...

Page 13: Calibration
Results in a lack of bass in the All Genelec active monitoring systems have room response adjustments to compensate for room influences and retrieve a flat frequency response at the listening position. Analogue systems feature DIP switch tone controls while Smart Active Monitor (SAM) systems with digital signal processing can calibrate automatically with Genelec AutoCal. - Page 14 First set the measurement microphone at the ear height in the listening position (typical height: 1.2 to 1.4 m). Ensure that monitors are at correct distances and heights. Take a frequency response measurement. Analyse the measurement results and adjust tone control DIP switches to retrieve a flat and balanced frequency response for each monitor.
- Page 15 Large table or mixing console in front of the 4 dB @ 160 / 200 monitors may cause a boost around 160- 200 Hz. Some Genelec monitors have a desktop control DIP switch compensating for this boost. SAM systems’ AutoCal will frequency compensate for this effect automatically.

Page 16: Acoustic Treatments
Acoustic treatments Monitor calibration alone helps but may not be sufficient to resolve room acoustic problems. Audio production rooms are designed for monitoring and should receive adequate acoustic treatments to allow quality monitoring. Several room acoustic improvements are suggested here. However, using services of a professional consultant is highly recommended. - Page 17 First order reflections can have high level while subsequent reflections become smaller. Control room design minimizes the first order reflection level reaching the listening area. Reflections arriving very soon after the direct sound from the monitor are called early reflections. One aim of control room design is to reduce or eliminate early reflections, having mainly the direct sound from the monitors reaching the listening area.

Page 18: Room Acoustics Improvements
Room acoustics improvements Several acoustic improvements can be made in a typical rectangular room where an audio monitoring setup is installed. Here are a few suggestions. - Page 19 Cut the room front corners at 30 degree angle using high-mass materials (concrete, bricks, multi layered gypsum board, etc). In case building materials have medium mass, be sure to fill the empty space behind these walls with mineral wool. Use a combination of absorption and diffusion on the side wall surfaces. Note that thin layers of porous absorbers only reduce HF reflections.

Sound basics Sound travels approximately 344 m/s (1130 ft/s). It takes 3 ms for sound to travel 1 meter (3,3 ft). In free-field conditions (no walls, floor, or ceiling) the sound volume drops 6 dB when the distance doubles. 100 dB 0 dB 94 dB -6 dB... -
Page 23: Sound Radiation
At higher frequencies, the radiation becomes directional: midrange frequencies radiate in a hemispherical pattern and very high frequencies can radiate in a beam- or ray-like pattern. Genelec designs monitors with controlled directivity and this minimizes the changes in the directivity across frequencies. -
Page 24: Radiation Space
Radiation space The radiation space is the volume into which a monitor is radiating sound. The sound level increases when the sound radiation is limited by walls. Every halving of the radiation space by a wall close to the monitor doubles the sound pressure level. -
Page 25: Cancellation Because Of A Wall Behind The Monitor
Cancellation because of a wall behind the monitor When there is some distance between the monitor and the wall, at the frequency where this distance is equal to one quarter of the sound wavelength, the wall reflection is out of phase with the monitor, and the reflected audio cancels the audio from the monitor. -
