Fig. 2.1: Control elements and connections

{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 select 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)

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-off frequency is 12 kHz.

{8} Use the EQ LOW control to cut or boost the bass range by 15 dB. The cut-off frequency is 100 Hz.

{9} The B1220DSP features a high-pass filter 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-off frequency. If you want to use the B1220DSP in combination with a subwoofer, you can use the high-pass filter 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-off frequency to the highest frequency that can be reproduced by the subwoofer.

(10)The CONTOUR switch governs the dynamic contour filter:

SPEECH

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

MUSIC

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

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.
