Unity gain is just what the name implies - the level leaving an amplification stage is the same as that level entering it. And that, of course, is also why it's called what it is. ;-) Best... -J :) --- * Origin: MIDIoholic Seattle, WA (1:343/226) --------------- FIDO MESSAGE AREA==> TOPIC: 200 PRO AUDIO Ref: CFA00000 Date: 11/05/95 From: JOE BEELS Time: 01:01pm \/To: JERRY KENNEY (Read 5 times) Subj: HELP SENDING .VOC TO COM1 *** Quoting Jerry Kenney to All dated 11-02-95 *** > How could I have volunteered but now the institution wants me to > give a reminder call to 995 families during Nov. and Dec. via a > phone call.

GODIN (Read 5 times) Subj: Unity Gain Scott R. Godin Digitally Said This In A Message To: ALL: SRG> Can anyone explain the concept of Unity gain, and why they SRG> call it that? Why they call it that is a mystery to me, but all it means is that the signal going out is exactly the same level as the signal coming in. The only purpose it has is to electronically isolate the source from the equipment you intend to use to process its output signal. Kind of like a TV repairman using an isolation transformer on his oscilloscope's main power line so when he touches the probe to the chassis of a TV with a hot ground - his scope won't blow into pieces. That may be kind of an off the wall example, but I really don't know of any other way to explain it without drawing a schematic to show you what it is and exactly how it works. ....Later.... ....Larry.... --- Shotgun v1.22 * Origin: ANSI/RIP/SVGA & Digital Sound - Freq SHOTGUN (4megs) (1:285/703) --------------- FIDO MESSAGE AREA==> TOPIC: 200 PRO AUDIO Ref: CFA00002 Date: 11/04/95 From: CHRIS HORN Time: 12:26am \/To: JERRY KENNEY (Read 5 times) Subj: RE: HELP SENDING .VOC TO COM1 Hi JERRY, at November 2nd 95, JERRY KENNEY wrote to ALL about: HELP SENDING .VOC TO COM1 [...] JK> so why not just let the PC send them my message if the answering JK> machine answers my call?

You need a voice-capable modem (e.g. ZyXEL or Rockwell-based), a software that provides voice-calls (VoiceConnect is great for that) and another fido-area ;-))) . Because VoiceConnect is a german shareware you will have problems gettin' it in the states, but if you're interrested send me a netmail.

What do you think about a 1:1 xfrmr, with an RC network to form an impedance of about 600ohms, connect that to an RJ-11 jack. The other side another RC network to match the output Z of the SB (say, 10kOhms?) How about (quick scratching of my noggin) Rout (RJ-11 side) seriesed with one leg of the xfrmr, and a .01uf cap accross the lines. The Input side (from the SB) a 1k (again, seriesed with the hot side of the output) and a .1uf accross the xfrmr leads... Hmmm...

GODIN (Read 4 times) Subj: Unity gain -> Can anyone explain the concept of Unity gain, and why they call it that? I guess the easiest way would be to relate to an EQ that offers unity gain. f you set a curve of some sort (anything other than "flat") on the EQ, it will affect the gain difference between input and output (could be higher -or- lower). If the device offers a unity gain adjustment (or does it automatically), you can set the EQ curve and adjust for unity gain; same voltage in, same voltage out, despite having changed the frequency response f the signal in -> out. This can be handy within the "chain" of either recording, or PA applications. --- * Origin: Lunar NetWork BBS Node #3 313-480-2853 vFC (1:2200/213) --------------- FIDO MESSAGE AREA==> TOPIC: 200 PRO AUDIO Ref: CFD00001 Date: 11/07/95 From: JOE BEELS Time: 08:47pm \/To: JEFF EDMONSON (Read 4 times) Subj: Help Sending .voc To Com1 *** Quoting Jeff Edmonson to Joe Beels dated 11-06-95 *** > SB > JB> and the phoneline. > > What do you think about a 1:1 xfrmr, with an RC network to form an > impedance of about 600ohms, connect that to an RJ-11 jack.
