hhmmmmmmmm............. Maybe they don't exist......... This device would need two independent inputs and outputs. I would be using this box in conjunction with my digital piano, snake, and recording interface. Signal Chain 1: Piano stereo Headphone output -> TRS Headphone Jack input on the...

I'm looking for a piece of equipment that will do the following: - Convert a headphone output to two balanced outputs - Convert a balanced line output to a headphone output. Does this exist? I've spliced some schematics and could build one myself. I'm just hoping somebody makes one!

My Behringer ECM8000 had a problem so I opened it up. The first time I tried to pull the guts out it required a lot of force, so I gave up, because I needed to use it. I opened it up tonight with force and ended up breaking the wires that lead from the capsule to the pcb board. Yikes!! How...

I brought this up with my instructors and they were baffeled as well... It didn't work for a simple DC comparator!! Looks like I'll look into different comparator circuits or perhaps a different type of clipping idicator circuit!! Thank you very much for your help, though!! It would have been...

not much. (.2mA or so) I used a 50K pot to set the reference voltage level.

yeah, I've created a voltage divider to give it a reference of 2.4V (max for half of the wave) but as soon as I plug it into the opamp terminal the voltage is no longer 2.4V. Wierd stuff like this keeps happening when I wire up the circuit. I works just fine in simulation, but when I wire it up...

Hmmmm.... I've been messing around with these comparator circuits and I'm having a but of trouble getting them to work right... Let me be a little more specific, I have half of an NE5532 opamp remaining after building my preamp, so I am hoping to use this as the comparator. I want my "clip"...

I'm building a preamp for an Audio to Digital converter and am looking for a schematic for a clipping indicator. I want the "clip" light to turn on just before I hit the 5V peak to peak threshold. Anybody know where I might stumble across such a circuit diagram?

Hi, I'm building a mic preamp with +12V and -12V on the rails of the opamp. How can I convert this voltage difference to 24V phantom power? I know it has to do with how you hook the resistors (usually 6.81K) up... Do i just send +12V through on resistor and -12V through the other...

The Gibson faded line is a bit different. They skimp on the finish to make the guitar more affordable. They don't charge extra to make it look like it was worn... it just doesn't get as much care in the cosmetic finishing process.

wait!! don't forget to compensate for the impedence mismatch caused by pulling two of the tubes!! It will effectively double the output impedence of your amp. So if you are using an 8 ohm cab, plug it into the 4 ohm tap.. many say this isn't necessary, but seriously, who would plug thier...

well..... I do!!!!!!!!!!!!!

ummm... no personally I think its a retarded idea unless you are a preformer who switches guiatars 20 times a night. Its just an electric guitar.. you can't play it without and amp... acoustic, my eye!!

ah man... I got the wrong idea when I read this thread title.... I was thinking someone wanted to pull thier power tubes out and use thier amp strictly as a preamp.... Technically it could work!! Maybe I'll try it someday....

yeah, well... For the love of Jeremy, whateevr you do, don't buy one of those cheap Berhinger A/B pedals..... It more of an A + Hiss / B + Hiss pedal... I'm completely dissatified with mine....
