User manual BEHRINGER VS1220F

[. . . ] User Manual EUROLIVE VS1220/VS1220F/ VS1520 High-Performance 600-Watt PA Speaker with 12" / 15" Woofer and Electro-Dynamic Driver Thank you Thank you for purchasing one of our EUROLIVE VS series loudspeakers. These loudspeakers offer powerful, pristine sound reinforcement in a lightweight, portable package. Furthermore, they can act as pieces to an expandable sound system, with ¼" TS inputs and outputs, pole mounting sockets and recessed handles. Heavy duty low-frequency drivers deliver thumping bass and powerful midrange clarity while high-frequency compression drivers cut through the mix with smooth, shimmering treble. [. . . ] Using ¼" TS speaker cables, plug the power amp output into the ¼" input on the back of the speaker. DO NOT use instrument cables (i. e. , guitar cords) for this connection! Fig. 2. 1 Connector panel [1] The VS series features two parallel ¼" TS loudspeaker inputs. You can connect one of the connectors to the output on your power amp and tap into the signal from the amp on the second connector, in order, for example, to feed this signal into an additional loudspeaker.

Imagine the loudspeaker is a giant flashlight, and you want to illuminate everyone in the room. · Avoid placing full-range loudspeakers in a corner or right next to a wall. This enhances the low frequencies and can cause the sound to get muddy. Subwoofers may be placed almost anywhere since low frequencies are not highly directional. · Make sure that the loudspeakers are not in a place where they could be knocked over by dancing audience members, overly eccentric stage performers, sudden earthquakes, etc. · Some rooms, such as gymnasiums and auditoriums, create a large amount of natural reverb, making it difficult to maintain intelligible sound. Laying carpet or rugs on the ground and curtains across windows or brick walls will help dampen the reflections and improve the overall sound. ENGLISH Fig. 2. 3 ¼" TS loudspeaker connector ATTENTION: Never connect the output signals of different power amps to both parallel inputs at the same time. This may permanently damage your equipment. When several loudspeakers are wired T in parallel, the overall impedance ZT to be handled by the power amp can be calculated, as shown here, from the individual impedance values of the connected speakers: For the VS series, here are typical connection scenarios: Two 8 Ohm speakers in parallel = 4 Ohms Four 8 Ohm speakers in parallel = 2 Ohms Two 4 Ohm speakers in parallel = 2 Ohms Four 4 Ohm speakers in parallel = 1 Ohm Your amplifier may be damaged if the actual impedance drops below its input impedance. Please make sure that the calculated total impedance ZT is not smaller than the minimum impedance specified for your amplifier. 3. 2 How to prevent feedback Always place the "front of house" speakers ahead of the microphones (from the audience's perspective), and never behind. Use professional floor monitors or an in-ear monitoring system to allow the stage performers to hear. 3. 3 How to avoid feedback when working with record players (DJ applications) 3. Optimal Operation We have developed the VS series for use in a wide range of possible applications. Of course, the sound of your loudspeakers depends on the acoustic characteristics of the room/space in which they are being used. The following chapters of this manual will give you information about getting the most out of your EUROLIVE loudspeakers. In applications with record players, bass feedback can occur. Bass feedback occurs when low frequencies get back to the pickup and are reproduced on the loudspeakers. The most common causes for this are: speakers located too closely to the record player, a room with a wooden floor, or presence of a podium or a platform. In such cases, it is best to move the loudspeakers away from the record player and remove them from the stage, so that they are located on firm ground.
