28 CALIBRA TING THE SUBWOOFER - with the main monitors Bass Management Bass management (sometimes called bass redirection), is a very important and useful tool - and it is in general an absolute necessity if you want to make a 5-channel setup in a small room! There are several reasons for this. The bass management system is designed to subtract the[...]

30 ACOUSTICS - BACKGROUND INFO Acoustics When we talk about making a room "sound right", we are probably dealing with room acoustics as a science acoustics has been around for about hundred years. Until then good acoustics happened by experiment, by experience, or simply by accident. T oday we know a lot about the p arameters that influen[...]

31 ACOUSTICS - BACKGROUND INFO Sabines formula Sabine is the father of modern acoustics. He found that reverberation time is described by a relationship between the room size and the amount of absorption in the room. Larger rooms - longer reverberation. More absorption - shorter reverberation. T = 0.161 * V / A where T : Reverberation time in secon[...]

32 ACOUSTICS - BACKGROUND INFO Diffusers A diffuser provides dif fuse reflection of the sound radiated against it. It can be a very useful solution in cases where reflections are disturbing the sound image and it is not advisory to ad further absorption. So in order to reduce flutter echoes, comb filtering etc., special elements can be placed on th[...]

33 BACKGROUND INFO - ACOUSTICS St anding W aves S tanding waves exist in all kind of rooms. The shape of the room, the dimensions of the room, and the relationship between the dimensions of the room, are important parameters that will determine the frequencies around which the phenomenon exists as well as the distribution of these standing waves. B[...]

34 ACOUSTICS - BACKGROUND INFO Room modes These special frequencies are also called room modes. S tanding waves between parallel walls are called axial modes. Other modes exist. For instance t angential and radial modes. (See the illustration). Normally the axial modes are the strongest. Axial T angential Radial[...]

35 ACOUSTICS - BACKGROUND INFO The standing waves are characterized by having a maximum sound pressure at the boundaries of the room. Depending on the frequency there are one or more dips across the room. In a box shaped room the frequencies can be calculated as follows: where f = frequency in Hz c = speed of sound (approx. 340 m/s or 1 130 ft/s) l[...]

ACOUSTICS - BACKGROUND INFO 36 At low frequencies a monitor can be considered as to radiate the sound energy in all directions. This is also called a 4 π radiation. When placing the monitor close to a solid boundary - for instance a wall - the sound energy that should have been radiated in the direction of the wall instead is radiated into the fre[...]

37 ACOUSTICS - BACKGROUND INFO Comb Filtering The filtering function that arises when a signal is added to itself af ter having been delayed in time is called a comb filter . The resulting frequency response resembles a comb, hence the name. T wo 500 Hz sinusoidal tones added. The second tone is delayed 1 ms hence the sum is zero T wo 1 kHz sinusoi[...]

ACOUSTICS - BACKGROUND INFO 38 T wo typical situations in which comb filters arise, either acoustically or electrically . In general: All digital signal processing takes time. This means in practice that comb filter effects can arise if you loop a signal via, for example, a compressor and combine this signal with the original. An example of a comb [...]

39 ACOUSTICS - BACKGROUND INFO Rear wall cancellation When the monitor is set up at some distance in front of a wall, reflections from the wall may occur and influence the perceived frequency response. This could result in comb filtering if all frequencies produced by the monitor were radiated in all directions. But the monitors are typically only [...]

THE SUBWOOFER - BACKGROUND INFO 40 The Subwoofer A subwoofer is a monitor that reproduces low frequencies. The purpose is to t ake over from the main monitor(s) as frequencies approach the lower end of the frequency range. I.e. approximately below 120 Hz. When used in professional monitor systems it is commonly preferred to use subwoofers below app[...]

41 THE SUBWOOFER & LFE CHANNEL - BACKGROUND INFO Checking summing phase cancellation In a basic 2-channel setup or 5-channel setup (like the ITU- 775) a subwoofer is not specified and is not required. But making audio production to be played back on consumer equipment, one has to ensure that the mix will sound right in this situation. Many cons[...]

In case of limited space the three front monitors can be arranged on a straight line. T o compensate the center monitor being closer to th[...]

43 LINE-UP & CALIBRA TION - BACKGROUND INFO Calibration of 5.1 in an ITU-775 arrangement In a 5.1 system based on the ITU arrangement, all main channels have in principle the same conditions: there is one monitor per channel and each is placed the same distance from the listener . Internationally , there is however neither agreement on the leve[...]

44 THE AIR REMOTE Introduction When perfect setup and calibrations is in place, optimal performance from the AIR system monitors is achieved by controlling level on the monitors themselves as opposed to controlling via the mixing console.
