Thank you  
Thank you very much for expressing your confidence in  
BEHRINGER products by purchasing the EUROLIVE B312A/B315A.  
This active and extremely compact loudspeaker has been designed  
specifically for those applications in which space is a problem.  
The compact dimensions and the low weight, despite the high-  
performance power amp give this product maximum flexibility. The  
input section accepts both line-level or microphone-level sources.  
Additionally, the loudspeaker has a 2-band equalizer for accurate  
high and lowfrequency control. All of these features make this  
loudspeaker a high-quality and highly reliable companion on the  
road.

1.3 Online registration  
1. Before You Get Started  
Please register your new BEHRINGER equipment right after  
the terms and conditions of our warranty carefully.  
1.1 Shipment  
Your product was carefully packed at the factory to ensure safe  
transport. Nevertheless, if the box is damaged inspect the unit  
immediately for signs of damage.  
Should your BEHRINGER product malfunction, it is our  
intention to have it repaired as quickly as possible. To arrange  
for warranty service, please contact the BEHRINGER retailer  
from whom the equipment was purchased. Should your  
BEHRINGER dealer not be located in your vicinity, you may  
directly contact one of our subsidiaries. Corresponding contact  
information is included in the original equipment packaging  
(Global Contact Information/European Contact Information).  
If the unit is damaged please do NOT return it to us, but notify your dealer  
and the shipping company immediately; otherwise, claims for damage or  
replacement may not be granted.  
Always use the original box to prevent damage during  
storage or transport.  
Make sure that children cannot play unsupervised with the  
unit or its packaging.  
Should your country not be listed, please contact the distributor  
nearest you. A list of distributors can be found in the support  
area of our website (http://www.behringer.com).  
Please ensure proper disposal of all packing materials.  
1.2 Initial operation  
Registering your purchase and equipment with us helps us  
process your repair claims more quickly and efficiently.  
Thank you for your cooperation!  
Ensure adequate air supply and to avoid overheating do not  
place the unit near radiators etc.  
Blown fuses must be replaced by fuses of the correct rating!  
Please refer to the “Specifications” section for the  
applicable rating.  
2. Control Elements and  
Connections  
For connection to the mains use the enclosed power cord with  
cold connector which complies with the relevant safety  
regulations.  
Please make sure that all devices are properly grounded.  
For your own safety, never remove or disable the ground  
conductors from the devices or on the power cords. The  
unit must always be connected to the mains outlet with a  
protective grounding connection.  
Caution  
!
This loudspeaker is capable of producing extreme volumes.  
Please keep in mind that high sound pressures do not only  
temporarily damage your sense of hearing, but can also  
cause permanent hearing damage. Be careful to select a  
suitable volume at all times.  
Important notes concerning installation  
Fig.2.1: Control elements and connections (B312A and B315A)  
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.  
[1] Use this ¼" stereo jack to connect a signal source that has  
¼" output.  
[2] Use this XLR connector to connect a signal source that has  
XLR output.  
Always use either the XLR or the ¼" jack input, and use the  
LEVEL control {4} to adapt the input sensitivity. Never use  
both inputs at the same time!

[3] The LINK OUTPUT is directly connected to the inputs  
of the B312A/B315A and carries the input signal with no  
processing applied. In this way, you can route the signal  
to the input of another device (for example, a second  
B312A/B315A)  
[4] To set the volume of the LINE or MIC signal, use the  
LEVEL control. The left half of the control range is for  
attenuating the LINE signal. The right half is for raising  
the level of the MIC signal.  
[5] The CLIP LED lights up when signal distortion occurs.  
Reduce the volume with the LEVEL control until the CLIP  
LED does not light up any more, or occasionally lights up at  
signal peaks.  
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 select a suitable volume at all times.  
[6] The HIGH control adjusts the high-frequency range.  
[7] Use the LOW control to raise the level of the low-frequency  
range.  
[8] The PWR LED lights up when the loudspeaker is put into  
operation.  
Fig.2.2: Control elements and connections B312A and B315A)  
[9] You can replace fuses at the FUSE SWITCH of the  
B312A/B315A. Always replace fuses with the same type.  
Please follow the instructions given in the chapter  
“Specifications.”  
[10] The mains connection is established using a cable with  
an IEC mains connector. This cable is delivered with the  
B312A/B315A. To avoid ground-loop hum, loudspeakers  
and mixing consoles should be connected to the same power  
circuit.  
[11] Press POWER to turn on your B312A/B315A.  
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 prolonged periods of time.

3. Application Examples  
4. Installation  
Turn the LEVEL control fully to the left before you switch  
on the unit with the POWER switch. Then, raise the volume  
to a suitable level.  
Both audio inputs of the BEHRINGER B312A/B315A and the  
LINK OUTPUT connector are fully balanced. To maximize  
interference compensation, try to establish balanced connections  
to other equipment, whenever possible.  
3.1 Using a mixing console  
A common way to use 2 B312A/B315A loudspeakers is with a  
mixing console. In this case, connect each of the main outputs  
that are on the mixing console to a B312A/B315A loudspeaker.  
The B312A/B315A includes XLR and ¼" connectors. To avoid  
interference, use only XLR or ¼" jack cables.

Make sure that only competent people install your  
B312A/B315A. They must be sufficiently earthed during  
and after the installation process. Otherwise, electrostatic  
discharges may negatively affect the operating characteris-  
tics of your equipment.

Fig. 3.1: Wiring several B312A/B315A loudspeakers using the LINK  
OUTPUT connector  
For larger rooms, you can connect several B312A/B315A  
speakers using the LINK OUTPUT connector {3} (see fig. 3.1).  
3.3 Direct connection of a stereo  
signal source  
When you use two B312A/B315A loudspeakers, you can directly  
connect one stereo signal source, for example, a CD player.  
In this case, each of the speakers is connected to 1 signal-source  
output. (If necessary, use the appropriate adaptor.)
