Switching AC Adapters Are Enemies Of Audio!

 

Never-ending pursuit for better sounds is the essence of pure audio. Its large enemy is the noises sneaking up from electric power supply. Not only audio equipments, but almost all electric appliances use direct current (DC) which is converted from alternating current (AC) of 100V. There are some using motors which use the alternating frequencies of 50Hz (in east Japan) or 60Hz (in west Japan), but the representative, air-conditionners, mount innverter since a few decades ago. Consequently, many switching AC adapters are currently used. They generate DC by repeating on and off of AC in very high frequencies. Switching AC adapters are efficient, small, light-weighted, and widely used. However, due to their fundamental mechanism,  they produce many noises. Therefore, audio equipments still mount large tranceformer power supplies, as before. High quality audio equipments tend to be heavier, largely because they have large enough capacity of tranceformer power supplies.

 

Audio-Grade AC Adapters Are Too Expensive...

 

However, devices particularly used for network audios, such as LAN router, hub, NAS, external DAC, have switching power suply either internally, or within an AC adapters. If you exchange them with clean transformer power supplies for audio, your audio sounds would be very effectively improved. Here is the issue that, these audio-grade AC adapters, each costs several hundred dollers, and you are not sure in advance, if the effects would justfy the large expenses.

 

 

cheeTarh Batter Kits For All Electric Voltage!

 

cheeTarh Consulting provides all audiophiles with a battery kit, which generates any volage DC, easily. Looking at the photos, and you may wonder, "oh, these are just battery boxes..." Hold on, please. cheeTarh Battery Kit consist of a battery box for tandem 10 of size AA (1.5V ) bateries which generates 15V, but by shortcircuiting unnecessary parts with a crocodile clip, it can change the number of batteries. So, you can change the voltage as you want. Moreover, by using rechargeable batteries, such as Eneloop, you can make the multiple up to 10 of 1.2V, which is up to 12V. If you allow me to run to extremes, if you have 2 sets of these, you can easily generate any DC of up to 30V (with 20 batteries), and can test which AC adapters affect how much, for the rest of your life. For those who say "well, well...Not a bad idea, cheeTarh Consulting always think of such kind of petty ideas. But, thank you for the idea, I always have some crocodile clips, and I will buy the battery box for ten AA, by myself, bye," it  really is time to say good bye. However, not all audiophiles enjoy the hobbie of electrical crafts, and have crocodile clips. The battery box for 10 AA by itself is not widely available, and the walk to a DIY store would be in vain. If you find one, it will be at maximum for 6 AA batteries. The crocodile clip you can find at home center would be a package of 10 of these, and cost ten dollars. Then, you find a cheap crocodile on net shopping, but would be surpised by careflly reading the review that some did not have the proper electrical connections. You will know later that In order to firmly pinch the + pole, the midium sized crocodile clip is better. Similar things happen with the snap cable, you can easily find one for solder, but not all of you are good at it. Finally, you will depend on a electrical parts net shop, but strangely enough, not all things are available at one shop, and you will be required to spend multiple shipping fees.

 

Specifications Of cheeTarh Battery Kit Premium!

 

With cheeTarh Consulting's Battery Box Kit, you can have all at once, with a reasonable price. For those who would think that they would use for long, and would like to have a nice looking one, if possible, with a switch and a plug adapter, here is the Premium set. You might wonder how long the batteries last, for example Eneloop Standard is 1900mAh. The consumption current of Planex FX05, a switching hub famous for the sound quality among audiophiles, is DC5V 300mA. Four Eneloop AA(4.8V, the photo shows 5.32V, though) would last 1.9Ah/0.3A= Approx. 6 hours. By buying eight Eneloop batteries, and by exchanging four of them repeatedly, it is actually possible to continuously supply the power, until you are fed up with exchanging them. It is not recommended for Eneloop, but when the voltage fall, you can add another used battery, and extend the the usage time of batteries. This kind of tips can be possible, as the bettery box is for as many as ten batteries.

Cautions:

 

※ Batteries, or eneloop & the charger need to be prepared by yourself.

※ If the DC plugs are different from 5.5/2.1 or 5.5/2.5, other DC plug adapters are necessary. Below kit is recomended, but you need to verify if the necessary sized DC plugs are included, in advance. If you purchse others, please confirm if the female side is 5.5/2.1【Broadwatch】 8 kinds of DC plug adapters, 680 yen at Amazon.

※ Fallen electric voltage might damage devices. Particularly, you need to take a great care for ones with HDD. This sale is conditional to  total self-accountability use principle. 

※ How to use crocodile clips seems simple, but unexpectedly, very confusing. Please open and follow "how to use Battery Kit" file, to avoid mistakenly shorcircuiting + & - poles of batteries.
