Replacing Phonomena BPS Batteries

日本に正規輸入されていないフォノイコライザ Musical Surrounding Phonomena と専用バッテリ電源キットを海外から中古で 購入 してから 5年以上が経過。さすがに充電式バッテリ電源ユニットもヘタってきたので、内部の充電池を交換。

Over five years have passed since I bought a second-hand set of Musical Surroundings Phonomena (and a companion Battery Power Supply unit) – nowadays BPS doesn’t work as expected, and it seems the rechargable batteries (in the BPS unit) have to be replaced.

Michell GyroDec Generations; Suspension Tower Upgrade Kit

こちらでは大変ご無沙汰しております。2歳を過ぎたやんちゃ娘を毎日自宅で面倒みながら仕事したり家事したりですと (笑) さすがにここの更新も疎かになってしまいがちです。今回はそんなやんちゃ娘の昼寝の間をぬって、ターンテーブルのパーツを交換したお話です。

It’s been a while since I updated this website last – I haven’t had enough time to post new entries here while I take care of two-year-old ‘tomboy’ daughter, doin’ daily household chores, doin’ my job all at home. Anyway the entry I am writing this time is a story of upgrading my turntable parts while my tomboy daughter was taking an afternoon nap…

Otono Edison Cartridges – 3mil version now available

以前 4mil バージョンしかないことを残念に思った (その時、メーカさんには「ぜひ 3mil バージョンもお願いします」とメールで切々と訴えておいたのですが) 音のエジソン の SP 用モノーラルカートリッジ。瀬谷さん から教えてもらったのですが、ついに 3mil バージョンも正式に販売されることになったようです。

While ago I wrote an article about Otono Edison monaural cartridge for 78rpms. When I wrote that article, there was only 4mil version available, while most of the 78rpms from “golden age” plays best with 3mil needle tip. So when I bought the cartridge, I wrote several e-mails to the company that they should sell 3mil version as well. Then in 2008, Otono-Edison finally decided to sell 3mil version as well as 4mil version – thanks Seya-san for letting me know.

しかし、5月に引越ししてから、まだ一度も SP 盤を聴いていません。ゆっくり音楽を聴く時間がまだとれずにいることもありますし、前の住まいより周りがあまりにも静かなので十分な音量で聴くのがためらわれる、というのもあります。最大の理由は、引越し後のどたばたで、SP がすぐに手の届かない場所にいってしまったためです . . . 時間ができたら、まだ整理完了とは程遠い私の部屋をなんとか整理し直さないといけません。

BTW the bad thing for me is that, since I moved to a new apartment in May, I have never had a chance to listen to 78rpms – maybe because I haven’t had enough time to fully enjoy listening to music, or maybe because this new place is too quiet all around (which is a very good thing for my sweet little baby, now in 9 months old) and I feel I hesitate to play vinyl/shellac records at louder volume as I used to do. But the most probable reason is, that I had been very busy and confused while moving/restoring whole lot of stuffs, and cardboard boxes which contains my 78rpm collection are out of reach behind my other stuffs (books, cloths, other boxes et al.) – so the first thing I have to do after I have spare time is to do another cleanup in my room . . .

Can you still hear 18kHz?

以前から気にはなってたんです。オーディオのはなし。

I have been wondering about that. It’s about audio in a different point of view.

受け取り手である人間の耳の特性が人それぞれバラバラなんやから、みんな同じ音に聞こえるわけないやん、って。

I mean, does all people listen to the very same sound, even though the listener’s audibility (in sound frequency) is different each other?

以前から携帯電話の呼出音として使うとどうよ? ってな感じで一部で話題になっていた Mosquito Ring Tone。幸い、私はまだ 18kHz も聞こえましたが、さすがに 2〜3回聞いただけで、耳鳴りがするというか、耳が疲れてしまいます。さて、皆さんはどこまで聞こえますか?

The famous Mosquito Ring Tone, which is inaudible for most adults, has been used among teenagers as a ring tone for mobile phones. Luckily I can still hear 18kHz sine wave (at least now), but after listening to it several times, my ears do complain that they are very tired and I feel bad… Anyway, can you still hear all high-frequency tones?

相も変わらず忙しくて、以前の様に音楽に浸る時間を十分に割けない日々が続いていますが、 今回は SP 用のカートリッジを追加購入したお話を . . .

I’ve still been very busy, unfortunately, and I can’t have enough spare time to devote listening to vinyls and 78rpms – oh my. Anyway this time, here is a story of another 78rpm cartridge I bought several days ago . . .
