Guide to Choosing Audio and LED Display Systems for Events

When it comes to organizing a successful event, the choice of audio and visual equipment can make or break the experience. In this comprehensive guide, we’ll explore the key factors to consider when selecting speakers, amplifiers, mixers, and LED displays, ensuring your event delivers an engaging and memorable experience for attendees.

Part 1: Choosing the Right Speakers

Speaker Type:

There are two main types of speakers: passive and active. Passive speakers require an external amplifier, while active speakers have a built-in amplifier. Consider the space and setup requirements of your event when choosing between the two.

Frequency Response:

The frequency response of a speaker determines the range of audio frequencies it can reproduce. A wider frequency range generally results in better sound quality. Look for speakers with a frequency response of 20 Hz to 20 kHz, which covers the entire audible spectrum for humans.

Power Handling:

The power handling of a speaker refers to the amount of power it can handle without being damaged. Ensure that the speakers you choose can handle the power output of your amplifier.

Sensitivity:

Speaker sensitivity measures how efficiently a speaker converts power into sound. A higher sensitivity rating means that the speaker will produce more volume with less power.

Impedance:

Impedance is the resistance of a speaker to the electrical current flowing through it. Most speakers have an impedance of 4, 8, or 16 ohms. Make sure the impedance of your speakers matches the output impedance of your amplifier.

Part 2: Selecting the Best Amplifier

Power Output:

The power output of an amplifier should match the power handling of your speakers. An amplifier with too little power may not provide enough volume, while an amplifier with too much power may damage your speakers.

Class of Operation:

Amplifiers are classified as Class A, Class B, Class AB, or Class D. Each class has its advantages and disadvantages in terms of efficiency, distortion, and heat generation. Class AB amplifiers are a popular choice for live events due to their balance of efficiency and sound quality.

Signal-to-Noise Ratio (SNR):

The SNR of an amplifier measures the ratio of the desired signal to the noise generated by the amplifier. A higher SNR means better sound quality. Look for amplifiers with an SNR of at least 90 dB.

Inputs and Outputs:

Make sure the amplifier you choose has the necessary inputs and outputs for your setup. This may include XLR, 1/4-inch, or RCA connections.

Part 3: Mixers and Their Role in Audio Systems

Inputs and Channels:

The number of inputs and channels on a mixer determines how many audio sources you can connect. Consider the number of microphones, instruments, and other sources you’ll need to accommodate when selecting a mixer.

Signal Routing and EQ:

Mixers allow you to adjust the volume, equalization, and routing of individual audio channels. Choose a mixer with enough control and flexibility to meet your event’s needs.

Effects and Processing:

Some mixers come with built-in effects and processing, such as reverb, compression, and delay. These can be useful for enhancing the sound quality and adding creative touches to your audio mix.

Part 4: LED Display Technology

Pitch Size:

LED pitch size refers to the distance between the centers of adjacent LED pixels. A smaller pitch size results in higher resolution and better image quality. The ideal pitch size depends on the viewing distance and the size of the screen. As a general rule, a pitch size of 1.2mm to 3mm is suitable for indoor events, while a pitch size of 4mm to 6mm is more appropriate for outdoor events.

Brightness:

LED displays should be bright enough to be visible in various lighting conditions. For indoor events, a brightness of 500 to 1,000 nits is usually sufficient. For outdoor events, a brightness of 2,000 to 5,000 nits is recommended.

Curvature:

Curved LED displays can provide a more immersive viewing experience and better viewing angles. Consider the layout of your event space and the desired audience experience when deciding between a flat or curved LED display.

Pixel Density:

Pixel density is a measure of the number of pixels per square meter. A higher pixel density results in better image quality and detail. For most events, a pixel density of 100,000 to 200,000 pixels per square meter is sufficient.

Choosing the right audio and LED display systems for your event is essential for delivering a memorable experience. Check out our dedicated site If you need technical help for your event in Japan.

Safe Data Erasure in Japan

Data erasure, also known as data wiping, is the process of permanently deleting data from a storage device. This is often done to protect sensitive information and ensure that it cannot be recovered. One of the most common methods of data erasure is known as the Department of Defense (DOD) erasure method.

The DOD erasure method involves overwriting the data on a storage device multiple times with a series of 1s and 0s. This makes it nearly impossible to recover the original data, even with advanced data recovery techniques. The DOD recommends performing this process at least three times to ensure complete data erasure.

Data erasure services can be used to wipe data from laptops, desktops, and servers. This is often done when a device is being retired, sold, or repurposed. By wiping the data from the device, businesses can protect themselves from the potential consequences of data breaches, including financial loss, damage to their reputation, and legal action.

In addition to using data erasure services, there are other steps businesses can take to protect themselves and their sensitive data. These include regularly backing up data, encrypting sensitive information, and implementing strict access controls to prevent unauthorized access to data.

Overall, data erasure is an important aspect of data management and security. By using data erasure services and following best practices, businesses can protect themselves and their customers from the risks associated with data breaches.

Starlink arrives in Japan and installation review

Starlink was activated last week for some areas of Japan that includes Tokyo and Kanagawa all the way north to Akita. Hokkaido and other areas south of Tokyo do not seem to be available yet, but I expect it will be working soon.

Starlink coverage area in Japan as of October 2022

On Monday this week we received what is probably one of the first Starlink antennas in Japan.

The parcel is shipped from California but it arrived very quickly by DHL in 3-4 days after the order. The outer box had some damage from the shipping, but the equipment inside is protected inside a plastic casing, so it was all fine.
The parcel is quite big you can see some measurements in the images below.

When you open the box there is a big white sheet with some Ikea style mount manual. The connection is very easy and before the final installation on the roof we just set it on a table and we had it working in just 2 minutes.

When you power on the antena will move automatically to find the best position.
So be careful not to have anything around it.

Then you need to download the app:
Android: https://play.google.com/store/apps/details?id=com.starlink.mobile&hl=ja
iPhone: https://apps.apple.com/jp/app/starlink/id1537177988

The initial wifi name will have the word starlink on it. It will not have a password so you can connect to the wifi without a password. Then from the mobile app you can change the wifi name and set up a password.

That is all for the installation. Wifi is working and we are getting very high speeds.
We are seeing that the speeds are almost similar to the fiber Internet although the Internet speeds may vary depending on the time of the day and how many satellites are available as well as general network congestion.

The primary use is for remote areas that do not have good internet connection.
For example the ministry of defense is planning to install it on ships to make life in the ships better:
https://www.jiji.com/jc/article?k=2022082000302&g=pol

It can also be very useful for businesses that need a backup Internet connection for emergency use.

Best effort speeds for each contract type

Each satellite beams a cell of around 24Km. You can see the cells as an hexagon on starlink website https://www.starlink.com/map. That means that the capacity is the same in a 24Km cell in the middle of the sea or in Tokyo. Because of that there is only a short window during which you will be able to get a starlink lines in the big cities. For example in many areas in the USA such as san francisco or Los Angeles, you can not buy starlink anymore as they already have as many customers as the satellites can support for that area. We expect the same will happen in Tokyo and other cities in Japan. Also you may notice that the speeds get lower once the number of starlink terminals are maxed out in your area.

The starlink constellation of satellites is still increasing, so the speeds and number of terminals that can connect in an area will increase with time, but there will always be a limit for crowded areas.

After you buy starlink you can only use it in the designated area, but you can request moving it to a new area. However if for example you buy it for a location in Tokyo, then you move it to Akita, and then you want to move it back to Tokyo you may not be able to do that if all the slots have been filled for your area in Tokyo.

There is also a business level starlink that costs $500 per month with higher speeds and I expect when the internet is crowded they will give priority to the customers on this plan.

I hope this review was useful for anyone considering starlink in Japan.

We can help Business customers install and integrate starlink on their company network in Japan. Other services we provide are IT warehouse and kitting, data center support, and audio visual installations and maintenance.

Why It’s Important to outsource your It staging requirements in Japan

The pressure to meet customer demands has never been higher than it is today. Your clients may switch to your competitors if you don’t deliver accurate orders quickly, who will take advantage of your deficiencies.

IT warehouse in Japan

Fortunately, there are some straightforward ways to step up your operational efficiency in Japan. One of the most effective solutions is externalize your warehouse and kitting process. In addition to helping you maximize warehouse space and resources, out flexible kitting system promotes faster product completion and delivery. The end result is increased client satisfaction and a healthier bottom line. Below is a look at the top reasons why you should automate your kitting process.

What are some challenges of manual kitting and staging?

Before diving into the benefits of our staging system, it is helpful to understand the weaknesses of the current warehousing market in Japan:

– Usually the minimum you will be able to rent a warehouse for will be 2 to 3 years. If your project is short term of the length is not clear you will have to commit to a long term contract that may be unnecessary. On top of that there are often associated fees with the rental such as guarantees, deposits and other real estate agent fees that can make the start up fees very expensive.

– You will need to find and spend on leadership for your warehouse that is reliable and does not leave you for a better job after a couple of months. When there are staff changes, you will have to start this process all over again. This is no easy feat in today’s tight labor market in Japan.

– You will need to recruit and train the floor staff. This will be an ongoing effort as this kind of positions suffer a higher than average attrition rates.

– When there is a change in a project, either it finishes sooner or you get a new big project you may either find yourself with too many or too few staff. That could mean either slowing down the new project or paying for staff that you don’t need.

These limitations can hinder your company’s expansion and ability to handle large orders, and unless you address these inefficiencies, your repeat business and customer satisfaction might both suffer.

How does LOREATEC help solve these challenges?

1) Respond quickly in real-time to market demands

Outsourcing the warehouse kitting process can eliminate the difficulties listed above, enabling your company to move forward to new heights of achievement. By partnering with a kitting and assembly specialist with extensive experience, you can maintain tighter control over your inventory, process orders more quickly, and minimize mistakes. Here is a brief list of the most significant benefits of outsourced warehouse staging:

2) Save on warehouse space and racks

You may save money on storage space at your own premises by outsourcing. Fewer racks, labels, and lifts are required. For companies that occupy hundreds of thousands of square feet, space savings alone may be significant.

3) Reduce labor costs

You require more employees, office space, computers, and support equipment to support the additional employees. You may also find yourself investing in expensive dispatch companies to help get large requests out the door. Training time can also build up into a large expense.

What is the best way to introduce outsourcing to your warehouse kitting process?

If you do not have presence in Japan it will be an easier sell. As it can save the huge expense ofsetting up your company and all supporting staff in Japan.

However if you already have operations in the country introducing outsourcing into your warehouse operations is not always easy You need to secure the buy-in of your leadership team by describing exactly how the short-term and long-term benefits outlined above will impact each department in your organization. Then, you can begin incorporating the process into your supply chain operations.

The single best way to introduce outsourcing to your IT warehouse and staging process is to contact one of our experts.
