----------------------------------------------------------------
修理完了報告書」添付。
広帯域、低歪率、高安定性、高信頼性 の本機ですが、
流石に経年の経過からの不安が否めません。
が、今回は出品に当り、メーカーにて現状動作チェックを行いました。
現在の状態・使用方法 の記載有。
ご確認して下さい。
----------------------------------------------------------------

□仕様(チラシ)
・インピーダンス 
・クロスオーバ周波数 500,2k,7kHz
・減衰特性 -12dB/oct
・アッテネータ 0~-20dB 2dBstep
・外形寸法 W430×H147×D540㎜
・重量 17.5㎏

□ネットワークの特徴
・広帯域、低歪率、低損失、低直流抵抗
・同一クロスオーバー周波数のハイパス側とローパス側の位相差が、180°となる理論バターワース特性を実現
・トランス式のATTを採用しています。

□LO-MID帯域のATT(アッテネーター)に付いて
・500Hz以下の周波数帯域をフルに取扱う場合「THRU」にて使用。
・500Hz以下の周波数の内 低域を「125Hz以上・-12dB/oct以上」の帯域の入力とした場合のみ 「PASS」ATTを使用できます。
(125Hz・-12dB/octのチャンネルディバイダーのハイパスフィルターを経由しての入力時に 125~500Hz帯域の 出力レベルの調整を想定)
修理完了報告書」に詳細有り。

☆あくまで私見
チャンネルディバイダーに依る、マルチアンプシステムを組まれている方々に。
クロスオーバ周波数が使える範囲であれば、必聴です。
本機に入れ替えれば、驚けますョ
「今更ネットワーク?」その気持ちは判らないでも無いですが・・。
その想像を超えてます。
見通しがグンと良くなります。
但し、各帯域のユニット及びパワーアンプのクオリティーが如実に露呈します
そこに不安のある方は、そちらの整備が優先事項かと・・・。

□着後3日以内の「音が出ない・あきらかに歪む」に
付いてのみ保障します。
ゆうパック(おてがる配送)にて発送予定

International Shipping Methods
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."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
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.
