VERSE SUB 215 MKII Руководство по эксплуатации онлайн [12/44] 757828

The acoustic characteristics of the room/environment in which a sound system is

used have sometimes very significant effects on the overall sound produced.

Thanks to its special technical features (such as the optimal width of its dispersion

range), with the VERSE SUB MKII some of the most common problems can be reduced

or prevented.

However, some factors should be borne in mind as they may help to optimise its

performance.

• Do not place speakers in the corners of a room or in recesses (e.g. niches), since

this causes an increase in the low frequencies, producing sounds which are

redundant or blurred.

• Do not place speakers against a wall, as this also causes an increase in the low

frequencies, although less pronounced than that produced in a corner or niche.

N.B.: on the other hand, this phenomenon may sometimes be used to advantage to

reinforce the low range, but it must be employed carefully and in a controlled way.

• Do not place speakers straight on a stage, a floating floor or any other support with

cavities, as this tends to trigger resonances that alter and interfere with the overall

sound.

N.B.: solid supports should always be used when possible, or a speaker stand.

• Remember that high frequencies have a high level of directivity and a much higher

absorption coefficient than low frequencies. Therefore, to guarantee that the signal

reaches the listener in an intelligible form, position speakers so that they are in a

direct line with the audience (clearly visible) about ½ metre / 1 metre above the

audience’s heads.

• In buildings with a lot of reverberation (places of worship, gymnasiums, etc.) first

of all keep the sound reflections down using materials which absorb sound

(carpets, curtains, special panels, etc.). If this is not possible or is not sufficient, do

not simply turn up the volume, because this will also increase the volume of the

reflected sound, and may make the situation even worse. The best solution is to

use more speakers, placed around the room and closer to the audience (e.g.

front+back; front+sides; front+sides+back).
