Thank you

Thank you very much for expressing your condence in BEHRINGER products by
purchasing the EUROLIVE B1220DSP. The B1220DSP is a state-of-the-art digitally
controlled PA speaker system that will simply blow you away. Its bi-amped
600-Watt engine drives a high-eciency 12" woofer for brutal punch and a

1.75" titanium driver for high-end resolution. The built-in mixer allows you to
run the show without any ex tra equipment. A powerful 24-bit DSP controls the
crossover, a dual compressor/limiter, phase and time corrections and even a noise
gate. Theintelligent dynamic EQ makes sure your system sounds perfect at any

5 EUROLIVE B1220DSP User Manual

1. Introduction

◊ Please read this manual to familiarize yourself with the control

elements of the unit and its functions. After you have carefully read
this manual, keep it for future reference.

1.1 Before you get started

1.1.1 Shipment

Your B1220DSP was carefully packed at the assembly plant to assure secure
transport. Should the condition of the cardboard box suggest that damage may
have taken place, please inspect the unit immediately and look for physical
indications of damage.

◊ Damaged equipment should NEVER be sent directly to us.

Please inform the dealer from whom you acquired the unit
immediately as well as the trans port ation company from which you
took delivery. Other wise, all claims for replacement/repair may be
rendered invalid.

◊ Please always use the original packaging to avoid damage due to

storage or shipping.

◊ Never let unsupervised children play with the B1220DSP or with

its packaging.

◊ Please dispose of all packaging materials in an environmentally

friendly fashion.

1.1.2 Initial operation

Be sure that there is enough space around the unit for cooling. To avoid
overheating, do not place the B1220DSP on top of power amps or near
radiators,etc.

The mains connection is made using the enclosed power cord and a standard IEC
receptacle. It meets all international safety certication requirements.

◊ Please make sure that all equipment is properly grounded at all times.

For your own safety, never remove or disable the ground conductor of
the unit or of the AC power cord.

Important note concerning installation:

◊ The sound quality may diminish within the range of powerful

broadcasting stations and high-frequency sources. Increase the
distance between the transmitter and the device and use shielded
cables for all connections.

2. Control Elements and Connections

(10)

(11) (12) (6)

(13) (5)

(1) Power is supplied via an IEC connector. The matching cable is provided with

the unit.

(2) Use the POWER switch to turn on the B1220DSP. Before connecting the unit

to the power mains, ensure that the POWER switch is in OFF position.

◊ Attention: The POWER switch does not fully disconnect the unit

from the mains. To disconnect the unit from the mains, pull out the
main cable plug or appliance coupler. When installing the product,
ensure the plug or appliance coupler is readily operable. Unplug the
power cord completely when the unit is not used for long periods
of time.

(3) Use the LEVEL control to adjust the signal gain of the MIC/LINE inputs.

Beforeyou connect or disconnect a signal source to or from one of the inputs,
please turn the corresponding control fully to the left. Once the signal
source is connected, increase the volume as desired by turning the control
clockwise. Always make sure that the CLIP LED (4) does not light up at all or
with signal peaks only.

Line-level signals:

Devices with high output levels (e.g. the outputs of mixing consoles or CD players)
only need little gain. In this case, the LEVEL control will mostly be positioned
somewhere in the area marked “LINE” (left half of the control range).

Microphone signals

Low-level microphone signals need more gain. When microphones are used,
thecontrol will be positioned in the MIC area (right half of the control range).

◊ We would like to draw your attention to the fact that extremely

loud sound levels may damage your hearing as well as your
headphones/loudspeakers. Turn the LEVEL control fully to the left
before you switch on the unit. Be careful to selec t a suitable volume
at all times.

(4) The CLIP LED lights up when the input signal level is too high. In this case,

turn the LEVEL control (3) to the left until the LED goes out or only lights up
at peak levels.

(5) Use the MIC/LINE inputs (XLR connectors) for connecting audio signals.

(6) The LINE OUT XLR jack provides the signal with no additional gain applied

in order to connect another loudspeaker, for example. The output signal is a
mix of both input signals. (See Chapter 4.2 for more information on how to
use several loudspeakers)

6 EUROLIVE B1220DSP User Manual

The B1220DSP is equipped with a 2-band tone control. Each band allows you to
apply a maximum boost/cut of 15 dB, in its center position the equalizer is set
toneutral.

(7) Use the EQ HIGH control to cut or boost the treble range by 15 dB. The cut-o

frequency is 12 kHz.

(8) Use the EQ LOW control to cut or boost the bass range by 15 dB. The cut-o

frequency is 100 Hz.

(9) The B1220DSP features a high-pass lter with a slope of 24 dB/oct.

toeliminate unwanted low-frequency content, such as pop sounds
producedby hand-held microphones, or rumble or wind noise when
using high-sensitivity microphones. The LOW CUT control adjusts the
cut-o frequency. If you want to use the B1220DSP in combination with
a subwoofer, youcan use the high-pass lter to lower the bass range
reproduced by the subwoofer. This allows you to operate the B1220DSP
evenwithout an external frequency crossover. Set the cut-o frequency to
the highest frequency that can be reproduced by the subwoofer.

(10) The CONTOUR switch governs the dynamic contour lter:

SPEECH

Setting the CONTOUR switch to SPEECH (switch not pressed) will optimize the
frequency response for speech applications. This ensures better intelligibility.

Fig. 3.1: B1220DSP mou nted on a stand

3.2 How to avoid feedback

Always place the microphones (viewed from the audience) behind the B1220DSP,
never in front of it (Fig. 3.2). When you wish to adjust the controls on the
B1220DSP while holding a microphone, please approach the loudspeaker from
the rear to avoid feedback.

MUSIC

Setting the CONTOUR switch to MUSIC (switch pressed) will optimize the
frequency response for music playback.

(11) The TIMED TURNOFF switch activates the automatic turn-o function:

ON

When the switch is actuated (ON position), the automatic switch-o is active.
Theloudspeaker is turned o auto matically when it receives no signal for more
than 3 minutes. As soon as a signal is received, the loudspeaker is switched
backon.

OFF

If the switch is not actuated (OFF position) then the speaker remains switched on
and can only be deactivated via the POWER switch (2).

(12) A noise-gate allows you to eliminate unwanted noise during signal pauses.

This is done by a circuit that mutes the output when the signal level drops
below a preset threshold. Use the NOISE GATE control to determine the
threshold below which the noise-gate closes.

(13) The TH LED lights up as soon as the signal level drops below the threshold

value adjusted with the NOISE GATE control (12) (the noise-gate closes).

3. Setting Up the B1220DSP

The sound of your B1220DSP largely depends on the room acoustics.
Pleaseobserve the following hints to get the most out of your B1220DSP.

Fig. 3.2: Right and wrong positioning

To avoid feedback, it is recommended that you carefully select and direct the
microphones used. Basically, you should use microphones with a high directivity,
i.e. with a cardioid or hyper-cardioid polar pattern. Never hold a microphone so
that its main pick-up area points directly towards the loudspeaker. When you
hold it with its less sensitive side towards the speaker box, you can move closer
to the speaker.

◊ If you encounter persistent feedback problems, consider using our

proven FEEDBACK DESTROYER PRO FBQ2496 for line-level signals.
For signals with line or microphone level, we recommend our
BEHRINGER SHARK DSP110.

4. Application Examples

4.1 Presentations

With just one B1220DSP and one or two dynamic microphones, you can set
up a basic audio system with very little eort. Thanks to the built-in mixer
section, you can connect the microphones directly to the B1220DSP. Mount the
B1220DSP on a speaker stand for optimum presentation and intelligibility of
announcements. If one B1220DSP is not enough, you can, of course, use a second
or even more loudspeakers.

Connecting microphones:

• Turn the LEVEL controls (3) fully to the lef t

3.1 Tweeter

High frequencies are the very part of the audio spectrum that ensure a clear
perception of sound and speech intelligibility. Although these frequencies can be
located most easily, they are also the rst to be blocked acoustically. We therefore
recommend that you set up your speakers on speaker stands (not included),
sothat the tweeter radiates its signals slightly above the heads of the audience.
This will ensure both an optimum dispersion of the high-frequency content and a
considerably improved speech intelligibility.

• Connect your microphones to the MIC/LINE inputs

• Switch on the B1220DSP

• Turn the LEVEL controls (3) gradually clockwise to set the volume of your

choice. Observe the CLIP LEDs while adusting the volume. Make sure they
never shine constantly but only light up at peak levels

• Use the LINE OUT connector (6) to connect an (optional) second B1220DSP

7 EUROLIVE B1220DSP User Manual

◊ Never place a microphone directly in front of the loudspeaker owing to

danger of feedback! When operating the B1220DSP make sure that you
always stay behind the loudspeaker to avoid feedback.

Fig. 4.1: Connecting microphones

4.2 PA systems

PA is short for “public address” and includes all applications that involve a larger
audience. This example uses a mixing console as its central unit for system
operation and connections. All microphones, feeding and eec ts devices,
etc. are connected to the mixing console, which is then linked to the B1220DSP.

Connecting a mixing console:

• Turn the LEVEL controls (3) fully to the lef t

• Connect the left output of the mixing console to the MIC/LINE connector

of the left loudspeaker, and the right mixing console output to the
rightloudspeaker

• Switch on the B1220DSP

Instead of a mixing console, you can also connect a stereo signal source,
e.g. a CD player. In this case, one B1220DSP is connected to each of the outputs of
the signal source.

Connecting a stereo signal source:

• Turn the LEVEL controls (3) fully to the lef t

• Connect the left output of the stereo device to the MIC/LINE connector of

the left loudspeaker, and the right stereo device output to the MIC/LINE
connector of the right loudspeaker

• Switch on the B1220DSP

• Raise the output level of the stereo signal source (if available), ensuring that

it does not overload the input

• Turn the LEVEL controls (3) gradually clockwise to set the volume of

yourchoice

Linking several B1220DSP:

If you need more sound pressure, for example in larger rooms, simply increase
the number of loudspeakers on each stereo side. You could place two B1220DSP
on each stereo side and interconnect them (see Fig. 4.3). The loudspeakers can be
stacked or placed one beside the other. When you stack the speakers, thecarrying
recesses built into the cabinets ensure the stability of the stack. Youcan connect
a microphone, a mixing console or stereo signal source.

• Connect the LINE OUT connector (6) of the rst B1220DSP to the MIC/LINE

input of the next B1220DSP

◊ With several B1220DSP speakers connected to each other, their input

impedance will be reduced by half (two B1220DSPs), or to one third
(three B1220DSPs), etc. Always use the output impedance of the mixing
console as a basis for your calculations!

EUROLIVE B1220DSP EUROLIVE B1220DSP

4.3 Other uses

Monitoring:

When used as a monitor, the B1220DSP receives its audio signal from the monitor
or aux output of the mixing console. If additional B1220DSPs are to be used,
youcan loop the audio signal from the rst speaker to the next B1220DSP using
the line output. The sound and volume of each B1220DSP can be adjusted with
their own operating elements (3) (LEV EL), (7) (EQ HIGH) and (8) (EQ LOW).

Keyboard amplication:

Guitarists and bassists usually have their own ampliers on stage to make
sure they can hear their own instrument - even when no monitors are used.
vInwparticular on smaller stages, the power delivered by these amps is enough
to match the volume produced by other sound sources on stage. Things are
dierent with keyboards and synthesizers as these usually have no built-in
speakers. The B1220DSP allows you to connect and mix two keyboards. If you
want to play more than two keyboards, you can use a submixer (e.g. MicroMIX
MX400) to mix down the signals and route them to the B1220DSP using submixer
output connectors. The second MIC/LINE input can be used to connect the
monitor signal from the PA mixing console, so that you can also hear the other
members of your band.

5. Installation

Both audio inputs and outputs of the BEHRINGER B1220DSP are fully balanced.
Tomaximize interference compensation, try to establish balanced connections to
other equipment, whenever possible.
