アンプなどについている、Treble/Bassのことです。前から使っているTRIO TW-31の周波数特性がなにかおかしいので、 プリアンプ段についているCR型トーンコントロール回路を見直したところ、回路が逆に実装されているようでしたので、 10k、50k、100kの可変抵抗を用いた回路を再実装しました。
減衰が大きいので、両側にバッファアンプが必要となります。ボリュームはAカーブで、中央で15%程度を基準として作ってあります。 基本的には、C/Rの上下比がボリュームの抵抗比と同じになるようにすればよいはずですが、系列の中の数値を選ぶ必要があるので、 少々難しいかもしれません。
LTSpiceのファイルもありますので、簡単にシミュレーションできます。
TRIO TW-31に再実装した回路です。一部回路面の変更が必要となりました。
<rindolf> dazjorz: I considered switching my default nick to "shlomif", because that's how most people know me. <dazjorz> rindolf: yeah, it's your alternative nick now right? <rindolf> dazjorz: but then XChat2 reverted to the old nick and I was too lazy. <unreal> You seem to have many, well, stupid friends, rindolf :P <rindolf> dazjorz: yes, I have it registered. <rindolf> unreal: stupid? <Zuu> rindolf, noo! what to do about the tomato then? fish dont have big tomato noses! <rindolf> Zuu: fish? <rindolf> Zuu: I'll give you a tomoato. <Zuu> good question <rindolf> I'll give you the tomato back. <Zuu> where do i get fish from <Zuu> no no, keep it :D <rindolf> Zuu: my last name is Fish. * tommy_the-dragon slaps zuu with a fish <tommy_the-dragon> there ya go <dazjorz> rindolf: I just registered 'sjors' * rindolf gives a fish to Zuu <dazjorz> rindolf: as a nick. <Zuu> rindolf, thats just absurd, a reindeer with 'fish' as surname... <Zuu> your parents must have hated you <rindolf> Open source: "everyone contributes a fish, and in exchange everyone gets their own ocean." <rindolf> dazjorz: ah, cool. <Zuu> tommy_the-dragon, does dragons eat other animals, like fish? <unreal> Ocean == Big Momma's Bath? <rindolf> Zuu: I'm not a reindeer - I just play one on T.V. <tommy_the-dragon> not fish... <tommy_the-dragon> just reindeers <Zuu> tommy_the-dragon, what about fake TV reindeers ? <Zuu> Nice :D <rindolf> unreal: no, the whole enchilada. <rindolf> tommy_the-dragon: LOL. <tommy_the-dragon> and enchiladas <dazjorz> rindolf: I know someone whose nick is Stonehead, he made his three-letter acronym stn, but usually it's letters from the first name <dazjorz> uh <dazjorz> the full name <dazjorz> yours could be shf for example, and everybody would know "hey, that's shlomi" <dazjorz> but I'm at most sg, so I need to borrow another letter somewhere, or make it daz or just sjors * dazjorz thinks <tommy_the-dragon> my cat eats flies... <rindolf> dazjorz: I hate these three letter acronyms. <Zuu> shlomi really sounds like some dish made of reindeer <tommy_the-dragon> but hes lucky because i dont eat cats <rindolf> Zuu: heh. <unreal> heh <rindolf> tommy_the-dragon: I didn't know dragons had cats. <dazjorz> what's the name of the red-nosed reindeer again? <Zuu> it sounds edible at least <dazjorz> oh rudolf :) <rindolf> dazjorz: Randolph. <dazjorz> oh <unreal> I used to have a friend whos nick was "crap" <rindolf> unreal: wow. <dazjorz> <someguy> crap, someone stole my bicycle <dazjorz> <crap> ok? <rindolf> dazjorz: heh. <dazjorz> rindolf: why don't you like the three-letter acronyms? <rindolf> dazjorz: often too confusing. <rindolf> dazjorz: and two easy to mistype. <rindolf> dazjorz: and not too memorable. <unreal> LIS. <dazjorz> three easy to mistype, I think <rindolf> And often hard to pronounce. <dazjorz> maybe I'll just go with sjors <rindolf> too easy. Freudian. <rindolf> dazjorz: yes, I think that's a good idea. <unreal> (Lies, I say!) <dazjorz> hehe, rindolf++ # freudian <Zuu> or you could pick something girly and hope people will treat you nicer :) <rindolf> dazjorz: have you played with the farnsworth bot yet? <rindolf> Zuu: RinGirl <rindolf> Though nicks with "Girl " in them tend to draw too much attention. <Zuu> nah, it cant contain 'girl' that just seems fake <dazjorz> rindolf: I have <dazjorz> rindolf: remind me to fix knotify, khtml, and quassel :( <rindolf> dazjorz: nice. <rindolf> dazjorz: using MemoServ? <dazjorz> rindolf: the bugs annoy me, a lot, but I never get around to actually trying to fix them <rindolf> Zuu: maybe I should call myself "shlomi". Americans will think I'm a girl. <Zuu> yeah, it kinda have a girlish sound to it <dazjorz> rindolf: call yourself shloma, dutch people will think you're over sixty and female <rindolf> dazjorz: heh. <dazjorz> let me rephase that <dazjorz> dutch people will think you're female... and over sixty <dazjorz> (oma = grandma) <rindolf> dazjorz: ah. <unreal> kloot. <rindolf> In Hebrew nouns that end with "ah" tend to be feminine. <dazjorz> shlomah? <rindolf> Seriously now, if I change my nick it will be to shlomif. <dazjorz> let's change our nicks at the same time <rindolf> Well, in Shlomi's case it would be Shlomith. <dazjorz> I will be sjors, you will be shlomif <rindolf> dazjorz: OK. * rindolf is now known as shlomif <dazjorz> shit, now I have to <Zuu> what does shlimif even mean ? * dazjorz is now known as sjors <sjors> Zuu: shlomi = his first name, f = the first letter of his last name <shlomif> sjors: hi. <shlomif> Zuu: shlomi fish. <sjors> hi shlomif <shlomif> Hi sjors <tommy_the-dragon> where does rindolf come into it? <shlomif> sjors: my nick is longer than yours. <Zuu> oh lol, and i just said his name sound girly :P * Zuu pat pats shlomif ^^ <shlomif> tommy_the-dragon: Rindolf was a dwarven warrior I played in AD&D. <tommy_the-dragon> ahh ok * shlomif gives Zuu his tomato back. <Zuu> :< <shlomif> Since I'm no longer a reindeer. <sjors> shlomif: that's just to compensate against something you have that's way shorter than mine <shlomif> sjors: LOL. <shlomif> sjors++ <Zuu> Erhmm.. shlomif! how come there's this big hole in it? <tommy_the-dragon> sorry... <tommy_the-dragon> my bad <Zuu> Hehe * shlomif doesn't like raw tomatoes. <shlomif> But I eat them with pasta, etc. <shlomif> Or as meat sauce. <Zuu> or in sandwiches <shlomif> sjors: anyway, welcome to ##programming <Zuu> or on reindeer nose <shlomif> sjors: I'll probably revert to "rindolf" after next disconnect. <shlomif> Zuu: after you cook the entire reindeer. * shlomif is a reindeer cannibal. <shlomif> Well, rindolf is. <Zuu> yes, but he ran away <shlomif> I also like dried and olive oiled tomatoes. <sjors> shlomif: I just changed my clients' settings to reconnect as sjors, too <shlomif> Well, I think I'll go to sleep. <shlomif> sjors: ah. <sjors> shlomif: it'll probably take a while to "adapt" to sjors instead of dazjorz <shlomif> sjors: well, enjoy your new nick. <sjors> and I still have dazjorz.com, and not sjors.anything * Zuu tugs shlomif in <sjors> thanks ;) <shlomif> Zuu: thanks. * Zuu quicly squeeses a fresh tomato onto shlomif's nose <sjors> shlomif: sjors.biz and sjors.mobi at most * shlomif doesn't have rindolf.{com,org,net} etc. <shlomif> sjors: maybe sjors.in <shlomif> I got a shlom.in <sjors> sjors.indahou.se <shlomif> sjors: heh. <sjors> sjors.ac, sjors.ag, sjors.am, sjors.at <sjors> hehe sjors.me <sjors> sjors.pl, too bad i don't really do perl anymore <shlomif> sjors: there's also .sh <sjors> sjors.sh, too bad I don't really do shell script a lot <shlomif> Or .im <sjors> sjors.tv, too bad I don't really watch.. <tommy_the-dragon> do you own a mobile? <shlomif> .tv are pretty costly. <sjors> meh I don't like sjors. anyway, so I'll just keep dazjorz for everything <tommy_the-dragon> yeah whats with that (the price of .tv)? <shlomif> tommy_the-dragon: it's the foundation of the economy of Tuvaly. -- Reindeers, Tomatoes and Normalising Nicks -- ##programming, Freenode I couldn't think of an interesting signature to put here... Maybe next time. -- One of Nadav Har'El's Email Signatures.
