EUROLIVE B1220DSP

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 effects 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 left.

=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.

=Raise the level of the mixing console output to a level of 0dB.

=Turn the LEVEL controls {3} gradually clockwise to set the volume of your choice. When the CLIP LEDs light up, this indicates that the maximum volume has been reached.

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 left.

=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 first 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!

B1220DSP specifications

The Behringer B1220DSP is a powerful and versatile loudspeaker designed to meet the demands of live performances, public address systems, and mobile DJ setups. Renowned for its robustness and sound quality, the B1220DSP stands out with its blend of advanced technology and user-friendly features.

One of the key highlights of the B1220DSP is its built-in DSP (Digital Signal Processing) technology. This allows precise control over audio characteristics, enabling the speaker to deliver optimal sound quality across various environments. The DSP features several equalization presets designed to enhance audio clarity and presence, making it well-suited for different applications whether you're playing music, delivering speeches, or conducting live performances.

In terms of power, the B1220DSP boasts a 550-watt Class D amplifier. The Class D design not only ensures high efficiency but also ensures the loudspeaker can handle demanding audio without distortion, even at high volumes. The speaker incorporates a high-frequency titanium driver for crisp highs and a robust 12-inch woofer for deep, punchy lows, delivering a balanced sound that is both powerful and articulate.

Portability is another significant advantage of the B1220DSP. Weighing in at manageable levels, it features an integrated handle making it easy to transport to various venues. Additionally, the design includes rugged enclosure materials that can withstand the rigors of frequent use, ensuring longevity and reliability over time.

Connectivity options on the B1220DSP are extensive. It features a variety of input channels, including XLR and TRS inputs, allowing for flexible integration with mixing consoles, instruments, and other audio equipment. The speaker is also equipped with professional-grade outputs for linking multiple units, creating a larger sound system as needed.

Another notable characteristic is the speaker’s ability to function as a standalone unit. With its onboard DSP, it can adapt to different performance needs without requiring additional external processing. This makes it particularly appealing for mobile entertainers or events where setup time is limited.

In conclusion, the Behringer B1220DSP combines advanced DSP technology, robust construction, and high-quality audio performance in a portable design. With its array of features and capabilities, it is an excellent choice for musicians, DJs, and anyone in need of a reliable loudspeaker that delivers impressive sound output.
