Does "sound quality improvement accessories" really work?[Car audio terms 2021]

This is a series that explains the meanings of each car audio one by one.Currently focusing on terms related to "accessories".This time, I will explain the "sound quality improvement accessories" that exert the effect of improving the sound.

Some of the "accessories" have items to improve the sound!

By the way, in car audio, the word "accessories" is often used in the nuances of "peripheral parts" as described earlier.In other words, the parts that are necessary to operate them, other than the main units with some mechanisms, such as the main unit, power amplifier, and speakers, are generally called "accessories."There are also items that should be called "sound quality improvement accessories".

Let's introduce what is there.First of all, from the "EWA-1", a prologue, a up-and-coming brand produced by Jeanline & Partners, which regularly imports popular car audio brand products such as Morel and Ark audio.

This is a product called "electromagnetic wave absorption earning board", which can block electromagnetic waves that affect car audio units from outside.There are various noise sources in the car.Each electrical product, an alternator for power generation, and a large -capacity battery for hybrid vehicles, from which they are more or more small, which affects car audio equipment and makes the sound muddy without knowing it.

However, for example, when this item is laid under a power amplifier, the sound is better because it has the effect of absorbing electromagnetic waves from the outside.The sound becomes clearer and the intonation expression of the performance increases.

"EWA-1" also demonstrates noise removal!

By the way, "EWA-1" is not just to lay and use.It also has an earning system that can be easily connected, and it has a further noise removal effect by connecting it to a power amplifier or processor.

There are two ways to use this earning system.You can select either a method of connecting to the power supply terminal or a method of connecting to the signal terminal.So, when using it, I would like to try both and choose the more effective one.It is recommended that the decision is left to the experienced professional.Therefore, this item is only sold via a pro shop.

By the way, this item is based on escart products that develop various "sound quality improvement accessories" for home audio.In other words, "EWA-1" is the tune-up version.It is optimized for cars by joint development between Jeanline & Partners and Escart.

And the "electromagnetic wave absorption earning board" for the home audio has already been used by many enthusiasts.In other words, it is a proven product.

By the way, the current model "EWA-1" is actually in a few stocks.That's because the second generation model is under development and the completion is near.So, the release time of the new product you are interested in is expected to be in November.By the way, the size has been reviewed in the next -generation model, and the range of use will be even wider.If you are interested, let's experience the effects of the new products after the launch of the new product.If you can feel the difference in sound with your ears, get it.

There are also items that can lower the noise level of car audio unit!

Next, I will introduce the VE-02 of Kyojo Seiko.This aircraft is called "in -vehicle body earth enhancement BOX", and can prevent noise measures for car audio equipment.Using this machine, it makes it difficult for car audio equipment to have noise.

The mechanism that works for sound is as follows.Inside the aircraft, a total of 11 plates, such as copper x 5 sheets + 5 brass (brass) x 5 sheets + stainless steel (SUS) x 1 sheet, are set at 0.5mm intervals, which will this.Demonstrates the effect of increasing the surface area.As a result, the resistance value of the equipment can be reduced, and the noise level drops.

By the way, the usage is as follows.It is only necessary to connect the minus power supply terminal such as a power amplifier to this unit.The wiring of the normal "body arms" is OK as it is.This machine is a second -generation aircraft, hit with the first aircraft.It is used by many car audio freaks.

In addition, the A.I.S Acoustic Improvement System, a brand Six Element in Taiwan, which is regularly imported by Ys Corporation, is also gaining popularity.

The mechanisms for each product of the company are as follows:Each is made based on silicon, and the silicon is added to the silicon with a natural rare material lantanoid.And this is released in large quantities of negative ions, and the work is more active in the flow of electricity on the part attached to the item.As a result, the sound is cleared and the resolution and amount of information increase.

Six elements have a variety of items with different shapes and mounting methods.If you are interested, I would like you to experience the effect once at the car audio pro shop you are dealing with.On top of that, if you can understand the effect, use it from affordable items.By the way, various products for home audio have been released from the company, and it has been highly evaluated in specialized magazines.The effect is origami.

That's it for this time.We will continue to explain technical terms that are difficult to understand after the next time.stay tuned.
