With the above considerations in mind, a total wattage of between 15,000 and 17,000 watts is desirable, as this will provide enough headroom for a quality audio performance along with a suitable volume level for all audience members.
Requirement:
15000watts/2000people = 7.5watts per person
In addition, it is also paramount for the audio quality to be consistently audible for all members of the audience. This will be achieved by utilising a system design configuration that focus’ on clarity and direction whilst also rendering itself sympathetic to the sensitive ears of the general public not attending the event.
The System
With a desired total power being between 15,000 and 17,000 Watts, the (PA) system consists of the following: * J8 Loudspeaker (D&B Audiotechnik, 2010) * Q1 Loudspeaker (D&B Audiotechnik, 2010) * JSub Subwoofer (D&B Audiotechnik, 2010)
The proposed Digital Line Array configuration will be ‘flown’; suspended 6+meters above ground. These DVA’s will be located on both sides of the stage. The 4 JSub Subwoofers will be equally spaced along the length of the stage, 2 Jsubs will sit atop the DVA, 2 will sit on the ground as to maximise the reach of the low frequency content.
Figure 1: Line Array Configuration
Figure 1 shows the relative configuration of 16 J8 Loudspeakers and 2 Jsub Units in a Digital Line Array. One can also see that the load support and
Sonance is a company at a crossroads, long established as the leader in high-end home theatre speakers, it is at an inflection point where it needs to decide whether it wants to be a high-end speaker producer served through customized dealer channels, or a mass market audio systems maker. The past decade has seen the rise of a new competitive threat, the demise of its dealer channel and the emergence of a highly informed and selective customer base which have all served to hurt the company’s prospects.
The concert had a large turnout, which I greatly enjoyed. If we compared this concert to our concert last spring, we had over three times the amount of people show up. The concert band was also larger this year, which resulted in a wider range of pitch and tones the band could reach;
We ended up sitting in the far back corner away from the general crowd. I loved how we used the field recorder along with the headphones because it gave me a good idea of how the recording would end up. Some stuff I did not enjoy about the concert and the room was the aspect of trying to organize the microphones, their stands, and the cords. In my opinion, all of the gear was, in a way, intrusive to the crowd and was very noticeable. I felt like the performer looking at 20 ft. microphone stands in the middle of the room would think about them too much during the performance. There were no other spaces for the gear due to the small size and the circular shape of the room. We made it work but that was really the only negative aspect of the space. It is never easy organizing a snake of cords when there are thirty people walking all around
The Soundcraft unit consists of a local rack and a stage box, each with its own input and output quantity. There are 16 analogue line inputs and outputs not inclusive of the 3 adaptable analogue microphone/line inputs on the local rack itself. The digital inputs and outputs on the local rack supports 8 pairs (16 channels) of Audio Engineering Society/European Broadcasting Union (AES/EBU) inputs and outputs as well as 64 channel Multichannel Audio Digital Interface (MADI) in and out via optical SC connectors. Additionally, a talkback microphone input and line output can also be located on the local rack.

You can set up your Sony system in a way that works for your lifestyle. The subwoofer's acoustic waves are non-directional, so it can be placed in any convenient location. The kit includes foot pads for the subwoofer's feet. This reduces vibration and helps to keep the unit balanced on uneven surfaces such as carpeting.
2) I would use my Mac 700 Washes #201 thru #204 to light up my stage with some cyan color and evenly distributed on both stage left and right with an intensity of 45 to create a very interesting look as I also use my Mac 700 profiles #301 thru #304 in a magenta spiral rotating gobo pattern with a very slow speed so that it goes very smooth with song as the band performs the chorus of the song.
The 1970’s would be the golden year for mixing consoles. Consoles now have 32 channel strips, with the capability of routing signals to different channels and also featured, EQ and Effects Sends, these types of boards would be dubbed ‘In-line Consoles’.
When it comes to the overall sound quality of stereo equipment and speakers, many will attest to the fact that vintage speakers carry a certain charm and superior sound quality over modern stereo equipment and speakers. Modern sound equipment just doesn’t seem to measure up, and no one knows this better than Audio Sound Solutions. Audio Sound Solutions, located in East Rochester, NY is the place where vintage speakers and stereo equipment are the name of the game! Specializing in the sales and repair of vintage sound equipment such as speakers, amplifiers, tabletop radios, cd players, and turntables, Audio Sound Solutions is able to offer professional and expert advice, as well as quality vintage products time and time again.
The speakers play a major role in in the PA system, the quality of the music relies on them. First, connect the kettle lead into the mains and the desk. The reason why you need kettle leads is because of their capacity to transfer more
The Local rack place at the same place with control surface and inside it is 2 Digital Signal Processing engine - Studer Score Live technology, with only 2 DSP cards will be capable of 64 inputs with 40-bit floating-point digital processor and one or multiple D21m I/O frames. The D21m high density I/O system holds up all the inputs and outputs to produce ultra-low noise balance mic amp and sends it to
Loudspeakers and Line Arrays play a vital role in live sound reinforcement. The main goal of line arrays is to evenly distribute the full range of frequencies and ‘loudness’ of the performance to the audience, no matter where the people are standing. Stage hands and audio technicians work together before a live performance in order to achieve the optimum sound quality for the audience’s satisfaction during their experience of the live event. Typically, traditional line arrays are set up by technicians on ground level. With the help of motorized hoists, the speakers are hanged or “flown” to be rigged at a specific height and achieve its J shaped curve- provided that the stage or venue is able to properly accommodate the speakers’ weight
promote its most unique and enhanced features, the shock and water resistance, as well as the high quality speakers. These will satisfy the needs of any consumer that has a passion for music as well as ease the fears of any customer that has experienced the troubles that
The VI4 system consists of three main components. They are the local rack, the stagebox and the control suface. The inputs of the local rack of the VI4 system consist of 3 analogue mic/line inputs, 16 analogue line inputs, 1 talkback mic input, 64 channel optical MADI in and 8 pairs of AES/EBU inputs.. The outputs of the local rack consists of 8 pairs of AES/EBU, 16 analogue line outputs, TB line output , LCR local monitor A analogue line outputs and LR local Monitor B analogue line outputs. The inputs and outputs of the stagebox consists of 48 analogue mic/line inputs and 24 analogue line inputs.
The variation constructed in this report is a standing wave with a dynamic microphone with design specifications established in ASTM C384.5970. This consist of a straight tube with a loudspeaker mounted at one end, the tube can be rectangular or cylindrical but must be uniform along its length. The pipe material must be hard and rigid so that sounds are likely to
