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.
