[. . . ] User Manual EUROLIVE VP1220/VP1220F/ VP1520/VP2520/ VP1800S Professional 800/1000/2000-Watt PA Speaker with 12"/15" Woofer and 1. 75" Titanium-Diaphragm Compression Driver Thank you Thank you for purchasing one of our EUROLIVE VP 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 both ¼" TS and professional locking-style 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. [. . . ] 2. 3 ¼" TS loudspeaker connector [1] The VP series features two locking professional loudspeaker [1] connectors that are wired in parallel. 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. Pins 2+ and 2- are not connected. When several loudspeakers are wired in T parallel the overall impedance ZT to be handled by the power amp can be calculated, as shown below, from the individual impedance values of the connected speakers: For the VP 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. 2 Professional loudspeaker connector ATTENTION: Never connect the output signals of different power amps to both parallel inputs at the same time. [2] The VP series includes two parallel ¼" TS loudspeaker [2] 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. We have developed the VP 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. 3. 1 Loudspeaker placement Here are some tips to get optimal sound and performance from your loudspeaker(s): Elevate the loudspeaker at or above head level. High frequencies are the segment of the audio spectrum responsible for clarity and speech intelligibility. They can get muffled by the front row of the audience, so we recommend positioning your loudspeakers so the high-frequency drivers are slightly above the height of the audience. Imagine the loudspeaker is a giant flashlight, and you want to illuminate everyone in the room. EUROLIVE VP1220/VP1220F/VP1520/VP2520/VP1800S User Manual 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. 4. Additional Considerations 4. 1 Length and diameter of loudspeaker cables Loudspeaker cables whose diameter is too small can considerably limit the power amp performance. As a result, musicians often simply "turn up" the amp, which can lead to loudspeaker damage. Cable diameter should be at least 14 - 12 gauge. 3. 2 How to prevent feedback 4. 2 Power amp rating 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) Selecting the right amp can turn out to be rather difficult. Therefore, stick to the following rule of thumb: the power rating of your amp should be roughly twice the loudspeaker load capacity.
