Behringer shark fbq100 инструкция на русском

Аудиосистемы в концертных залах и на открытых площадках для выступлений, в конференц-комнатах и лекционных аудиториях одинаково подвержены акустической обратной связи – неприятному артефакту звучания, проявляющему себя как каскадное усиление определённой резонансной для данных динамиков частоты. SHARK FBQ100 – универсальное устройство, которое пригодится любому звукооператору, работающему с живым звуком. Оно позволяет находить и гасить все критические частоты, а заодно и служит промежуточным звеном между микрофонами и динамиками, способствуя улучшению конечного звука.

Функционал

SHARK FBQ100 работает по принципу системы узкополосных фильтров. Автоматическое детектирование позволяет находить и устранять до 8 проблемных частот, при этом в целом сигнал остаётся практически неизменным и приятным для слуха. Помимо обратной связи устройство может убирать паразитарные шумы, создаваемые некачественными микрофонами и сторонней электроникой, при помощи встроенного автоматически или вручную настраиваемого Noise Gate.

Дополнительно SHARK FBQ100 оборудован дэлеем с задержкой до 2,5 секунд, а также автоматическим компрессором с переменной плотностью и фильтром с настраиваемой частотой среза. Общая рабочая область частот лежит в пределах 10-21000 Гц. Соотношение сигнал/шум не превышает 92 дБ, искажения – 0,007%. Цифровой процессор, обеспечивающий обработку, работает с 24-битным сигналом с 64/128-оверсэмплингом.

Комплектующие и подключение

В 0,4-килограммовом устройстве помимо собственно цифрового процессора помещается ещё ряд комплектующих, обеспечивающих как чистую и качественную обработку, так и прямое подключение SHARK FBQ100 к линейным источникам сигнала. В частности, балансные XLR и ¼-дюймовый TRS входы подсоединены к отключаемому микрофонному предусилителю с отключаемым же фантомным питанием для конденсаторных микрофонов. Таким образом, к SHARK FBQ100 можно подключать и музыкальные инструменты, и микрофоны. Вход оборудован регулятором Mic Gain. Сервобалансные XLR и TRS выходные разъёмы совместимы с любым стандартным оборудованием, будь то динамики, микшер или ещё одно устройство обработки звука.

Для удобства управления настройками на передней панели устройства имеются светодиодные шкалы: уровня с отдельным индикатором клиппирования, и две – поиска критических частот для подавления обратной связи. Также имеются индикаторы, указывающие на режим работы дэлея, и четырёхзнаковый LED-дисплей, на котором отображаются текущие параметры фильтров.

4 SHARK FBQ100 User Manual

1. Introduction

1.1 The concept

With the SHARK FBQ100 you purchased a device that combines an automatic
Feedback Destroyer using the ingenious search algorithms of our FEEDBACK
DESTROYERFBQ1000, a variable Delay Line (adjustable in msec, feet and
meter), aULN (Ultra-Low Noise) microphone pre-amp with Phantom Power,
anautomatic Noise Gate, a variable Low Cut lter and a Compressor—all in
one ultra-rugged and compact case. Still, the SHARK can be operated intuitively
and expanded to a multi-channel system using another four SHARKs and
an optionally available 19″ rack mount kit. The SHARK’s 24-bit A/D and D/A
converters guarantee a precise reproduction of your program material.

High volume levels and the use of ever more sophisticated monitoring systems
with a multitude of speaker cabinets have led to a greater potential risk of
feedback loops in sound reinforcement systems. So far, audio engineers
have been using conventional 1/3-octave equalizers to suppress unwanted
feedback. However, the individual lters of such an EQ, with their relatively
wide bandwidth, have quite an impac t on the sound image. With the
BEHRINGER SHARK (minimum bandwidth: 1/60 of an octave) you are now free
to either choose the trial and error method to suppress feedback with graphic
equalizers, or to assign this task to the FBQ100, so that you can give your
music your undivided attention. Using extremely narrow-bandwidth lters,
the SHARKFBQ100 eliminates only unwanted feedback, without aecting
yourmusic.

Please use the enclosed power supply to connect the unit to the mains.
Thesupply complies with all applicable safety standards.

◊ Please note that all units must be grounded properly. For your own

safety, you should never remove any ground connectors from electrical
devices or power cords or render them inoperative.

Further information can be found in chapter 3 “Installation”.

As a standard the audio inputs and outputs of the BEHRINGER SHARK FBQ100
are fully balanced. If possible, connect the unit to other devices in a balanced
conguration to allow for maximum interference immunity. The automatic servo
function detects unbalanced connections and compensates the level dierence
automatically (6dB correction).

1.2 Before you begin

Your SHARK was carefully packed in the factory and the packaging is designed
to protect the unit from rough handling. Nevertheless, we recommend that you
carefully examine the carton and its contents for any signs of physical damage,
which may have occurred during transit.

◊ If the unit is damaged, please do not return it to BEHRINGER, but notify

your dealer and the shipping company immediately, otherwise claims
for damage or replacement may not be granted. Shipping claims must
be made by the consignee.

The optionally available rack mount kit allows you to mount your BEHRINGER
SHARK in a standard 19″ rack, together with another four SHARKs. The rack
mount kit requires 2U of rack space.

Be sure that there is enough air space around the unit for cooling and please do
not place the SHARK on high-temperature devices such as power amps, etc. to
avoid overheating.

(7)(6) (8)

(1) The CLIP LEVEL METER shows you whether or not the digital circuitry is

driven correctly. Any corrections can be made with the CLIP LEVEL control

(2). Be sure that the CLIP LED won’t light up.

(2) The CLIP LEVEL control lets you adapt the internal gain optimally to the

digital circuitry. If gain is too high (CLIP LED lights up), raise the CLIP LEVEL
value by turning the control to the right (and vice versa). Thus, you can shift
the operating level upwards/downwards.

◊ The CLIP LEVEL control does not affect the input/output levels,

but adapts the audio signal as optimally as possible to the threshold of
the digital circuitry.

(3) These ve LEDs symbolize the units of the parameters that can be adjusted

on the display (4).

(4) The 4-digit DISPLAY reads the absolute values of the adjusted parameters.

(5) The FB-D FILTER STATUS LEDs display the status of each of the 12 individual

lters. The SHARK uses four dierent lter modes:

• Disabled lters (which can be re-enabled with the ACTIVE button). When a

lter is o, its LED is not lit.

• Free lters which automatically search for feedback frequencies and whose

activity is shown by a ashing LED.

• Set lters which can be recongured as free (searching) lters, when all

lters are currently in use.

• Permanently set lters which must be RESET to be recongured as

freelters.

Once a lter has been set, its LED lights up.
