Sometimes people ask questions related to accessories, such as: "How does a table stand affect the sound quality of my monitors?" Well, let's see..
With the introduction of the 8020B
, Genelec is putting more emphasis on environmental care and improved usability.
It is well known that attenuation of the digital audio signal in a DSP processor decreases the number of significant bits representing the data. This is called quantization. Coarse quantization can lead to distortion if the data is not processed properly. Read further to learn how Genelec DSP loudspeakers work.
In fact, the complete question is: - how to precisely reduce the volume on Genelec DSP monitors in Stand alone 'stored settings' mode and keep at the same time the full dynamic range of the digital signal?
If you have an audio device with a stereo unbalanced output (1/4" TRS Stereo Jack or Mini-Jack), here is a short explanation on how to connect your Genelec monitors to it.
Every realistic room (with the exception of a perfect anechoic chamber) has a set of resonant frequencies. These frequencies and how much they boost the sound level at the resonant frequencies are defined by the room geometry and the surface materials. To learn more, read further!
Various technical committees have issued standards for surround sound reproduction. The AES Technical Committee is working in collaboration with the EBU and the SMPTE organisation. The Multichannel Audio Transmission Group (MCAT), which has members from the EBU, Dolby and DTS amongst others, is establishing standard procedures for multichannel audio transmission between European countries. The International Telecommunication Union (ITU) has issued many recommendations that are considered the reference ones.
Many people call the LFE channel the “subwoofer channel.” In fact, the LFE channel is the space on the storage media for the .1 encoded (and usually band limited) audio channel. The “subwoofer channel” is not a “channel” as such, as the subwoofer loudspeaker, together with the bass management system, replays a specific low frequency bandwidth.

A very common question is: how do I acoustically treat my room so that I get the best from my monitors? Well, this is a very large subject area covering room geometry, reverberation and decay time, sound reflection and refraction, material properties, etc, This month's Techtip highlights the most important features that a listening room should have.

As a general rule, the better mounting method is to place the monitors on stands behind the mixing desk and sufficiently high so that the bass driver is not obscured. Secondly, horizontally orientated monitors positioned on the meter-bridge of mixing desks may look nice but acoustically it is not a good idea. To learn more, read further!
An enclosed dynamic loudspeaker drive unit has theoretically ideal working conditions only if its frontal radiation space is either a full or a half space (i.e. spherical or hemi-spherical radiation). In practice the radiation angle decreases as the frequency increases first because of the finite size of the front baffle of the loudspeaker cabinet and secondly because of the size of the drive unit itself. When a loudspeaker is then placed near a wall, the wall presents an extension of the baffle of the loudspeaker at low frequencies, its frequency response will be modified, and we experience a bass boost.

Using a subwoofer with the crossover filter (typically at 85 Hz) between the loudspeakers and the subwoofer can improve the monitoring system. The high-passed loudspeakers (sometimes called ‘satellites’) do not reproduce low frequencies. They can now be placed at the walls more freely at distances where low frequency notching does not occur in their pass-bands.

A free standing loudspeaker is usually surrounded by boundaries that generate reflections (walls, ceiling and floor). These boundaries act as acoustical mirrors to the loudspeaker's radiation, enhancing or canceling the direct sound, depending on the phase difference between the reflection and the direct sound at the listening position.

The mechanism of cancellation is very simple. When two identical signals are in anti-phase (180 degrees out of phase), they cancel each other. If the loudspeaker is a quarter wavelength away from a reflective wall, the reflected wave comes back to the loudspeaker in anti-phase (phase difference of half a cycle) and thus cancels the original signal at that frequency.
