同時出品しているステレオ・マイク(ECM)をファンタム電源のXLRプラグに変換します。
ECMマイク駆動電圧は約6vです。

注意:市販品のECMマイクの作動電圧は公称2vですので、当商品は使えません。

 4-1)回路図
     回路は何の変哲も無い差動アンプの基本回路です。

 4-2)周波数特性
     20Hz~80KHzほぼフラットです。
     測定機材は以下を参照して下さい。
  http://edapyon.com/auction/XCM6035/

ECM動作電圧に付いて
 ファンタム電源48vを分圧回路で分圧、平滑して、ECM駆動電圧を約6vに設定してますが、
 ECMの消費電流ばらつきにより多少変動します。
 又、ファンタム電源供給源(オーディオインターフェース、レコーダー等)の仕様違いでも多少変動する。

 オーディオインターフェース(US-366)に繋いだ実測値は以下ですが、消費電流のばらつきで多少変動します。
(以下のマイク・カプセル作動電圧範囲は1.5v~10v)
 1)XCM6035:5.4v
 2)EM158:5.4v
 3)WM-61A:5.5v

ECM開放電圧に付いて
 ファンタム電源を出力し、3.5mmジャックを外した状態のECM出力端子電圧は約9vです。
 ECMを繋ぐとECMの消費電流に応じた電圧降下が発生して上記の印加電圧になります。

ファンタム電源出力状態でXLRプラグ着脱、及びECMプラグ着脱に付いて
 上記開放電圧が約9vなのでプラグ着脱してもマイクは壊れません。


録音出来ない等の問題以外はノークレーム、ノーリターンでお願いします。
万が一録音出来ない等の場合は返品に応じますが送料は落札様負担でお願いします。
 
尚、自作加工品ですので、加工の際に多少の擦り傷がありますがご容赦願います。
メーカー製の様な製作精度、美観を望む方や神経質な方は入札をご遠慮願います。

もう一度言います。
市販品のECMマイクの作動電圧は公称2vですので、当商品は使えません。

マイク仕様書に作動電圧が10v以下の記載がされていても、当方の未確認マイクは作動保証外ですのでご注意下さい。

Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)

1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
