Title: Metering, was JB3 metering
Post by: twatts (pants are so over-rated...) on November 02, 2003, 12:17:00 PM
Someone over at JB3 metereing had found some handy external meters...  But they are like $100...

Here are some cheapies that require a little workshoping:

And some more:

Not sure if these are the right things, but it is interesting...  Check out the star meter at Hobbytron...

nice finds! +T

this one http://www.hobbytron.net/vk4305.html looks perfect ... just solder on a  stereo miniplug and plug it into the headphone jack of the jb3. it could probibly run off the same battery as a UA-5. you could even get a realy nice one http://www.hobbytron.net/vk4306.html.

Dissclamer: I dont know shit! the most advanced soldering / electrical building project i'v done is the jordan shapiro battery pack.

Would it be better to hook these up somewhere else in the chain?  Seems to me that it would then take the headphone volume into account, which is not part of the recording...  so, the question is, is that the best place to put this in the signal chain?

Peace, and thanks-

Well, you could calibrate the headphone volume setting so that an over on the meter = probably about -2 on the deck or so. It may not be possible with every headphone output or this particular meter, though.

Could it be hooked up to the analog output of a preamp, assuming it has digital outputs being used for recording ?

i think it would be better from the pre than the headphone jack.  using the headphone jack would suck up the batteriesof the jb3, no?

thats what i would think, if you were gonna go out of the jb3, why would you go out of the headphone output? it has 2 analog "line outs" on the back that would be much better right?

i think someone was saying before that going analog out of your pre wouldnt do a great job...

but im stuck with a jb3 and a ua5, the worst combo for metering. so i might be testing one of these out real soon

i am buying the VU Meter - 2x15 LED Stereo VU Meter Kit
V-K4306 , it has terminal pins ready to be soldered to a 1/8 stereo jack, and seems to be ready to go with a tiny bit of soldering. il just build/make a handy little box for it... wish i had time before primus friday.... damn

from http://www.hobbytron.net/audiosub.html

assembled for 53.95, and a kit for 39.20. im just gonna stick with the pre-assembled package i believe

nice find!

I am prolly going to be stuck with that as well pretty soon... depending on what pre I decide to purchase, so I am very interested in any results you might find if you test this...  I want to add some kind of nice meter to my setup, but I am just not sure where...

I think the line out might of the NJB3 might not be a bad idea... I just got my nomad, so I am not sure about this, but with every other portable audio player that I have had, the line out jack is not subject to the volume of the headphones, so we would not have to worry about that, if the nomad works the same way!

Sorry for the thread change- I presume you are not stealthing at the Primus concert?    I saw on dat-heads that some people were having some problems taking in a complete rig, so I was thinking about stealthing...

At any rate, I am going to be taping them on Sunday in Detroit - trade SHNs?

Title: Re:Metering, was JB3 metering
Post by: caymanreview on November 03, 2003, 09:56:38 AM
primus is allowing open taping

must have been problems with the venue and not the band

we can definantly trade shn's. it will be my first run with the 3 mic mix... 2 cards and 1 omni... should be interesting

when i saw strokes/kings of leon a few weeks ago at the state theatre they were hard core about security.  they actually went up one leg, moved my junk to the other side, and then went down the other leg.  i know that strokes aren't open taping or anything, but the security was tight nontheless.  just a heads up, i don't know what it'll be like for primus.

i did notice that if you go in the side door to the bar first, they don't check ya, and just make sure you have a ticket before you go into the actual venue...that might be easier for getting gear in.

goodluck, i'll be there, but not taping, i think there'll be enuf of you, and i promised my friends i would actually enjoy this concert tape free...but i'd love copies, if its at all possible...i got lots to trade.

Thanks for the heads up.  I am thinking about calling up to the State and seeing how they are going to be about it.  I am also going there to see/tape Rat Dog, who will obviously be completely open, so I would imagine that I could talk to them then.

about using a vu meter with a ua-5, i think that would be really easy and quite effective!  think about it...it has rca outs on the rear, if those are active while outputting a digital signal say to your jb3, then you can get accurate levels right off the pre before it even gets to the jb3, just get a y-adaptor for twin rca's > 1/8" stereo.

oh, and if you've never been to the state, there are two balcony's, the top one hangs out over the bottom one a bit.  but the bottom one is right above the board.

If I rememeber correctly you can change the levels being output on the RCAs.  Point being, the levels being sent on the RCAs don't always match those of the digital.

I've had the same thought, but using the coax out.  As far as I can tell, it's not possible / easy to monitor the digital signal for levels.  The only devices I've seen are very expensive and involve doing D>A and then monitoring the analog output.  Calibration is obviously key...

What I thought would be a fun diy project turned into a wild goose chase.

One of the knobs on the front does it... I think the one above the phones jack

Post by: blu666z on November 07, 2003, 03:31:09 PM
I am at work right now and can't check but I think Lee has it right.  One is the headphones level and the other is output.

Post by: caymanreview on November 08, 2003, 11:43:22 PM
yes it says output above it, i havent messed with it to see if it does change the rca outs, assuming that it does. all the way up would put it at line level correct? making the meter accurate?
Title: Re:Metering, was JB3 metering
Post by: cpclark on November 09, 2003, 05:17:33 PM
im looking at my ua-5 right now, there is a master output knob on the front that controls all levels going out both dig and analog i believe, and then there is a seperate knob on the back between the optical and rca ins and outs that controls the analog in and out level, thats what everyone is referring to as the level knob for analog, i just keep it dead center in the middle for 0 gain if i were to use analog line level
Title: Re:Metering, was JB3 metering
Post by: caymanreview on November 09, 2003, 05:50:40 PM

Title: Re:Metering, was JB3 metering
Post by: caymanreview on November 09, 2003, 06:03:46 PM
yeah, that is just the analog output, and it does affect the rca outs to my knowledge, i just haventtested it for sure, i will be doing that tonight, also ordering the meter i mentioned on page 1 tonight too

What about this idea??

Unless the line-out on the jb3 eats the batteries (which it might) this seems like the best solution...

And did anyone even mention how they are planning to power the meter?  Will 9.6v batteries (like for the ua5) work?  Would it be possible to run both off one battery?

Are you guys really having so much trouble with the metering that you're gonna try something like the options posted here?

I ran a modSBM-1 for a while and could always tell where my levels were by the -2dB indicator lights.  I imagine with practice you could fairly easily do the same with the UA5.  Just a thought...seems like a lot of effort for something you'll get used to after a short period of time.

The UA-5 is kinda boring with it's one little light...  :)

Also I think people just like DIY projects...

I agree Dustin!  If there was a -2db light for each channel I would be VERY satisfied with my UA5.  

Do you have the manual???  If so can you check into the Master Output knob.  I want to know what it says about gain on the RCA outputs, I can't find my manual.  Seems like all the way down is line level, but I can't remember for sure.

I have it!

It says: "Master Volume: This adjusts the volume that is output from the headphone jack and the Master output jacks" -  and the manual designates that the master output jacks are the RCA outputs.

Guess that means the analog out isn't a good idea either... ???

i am buying the VU Meter - 2x15 LED Stereo VU Meter Kit
V-K4306 , it has terminal pins ready to be soldered to a 1/8 stereo jack, and seems to be ready to go with a tiny bit of soldering. il just build/make a handy little box for it... wish i had time before primus friday.... damn

from http://www.hobbytron.net/audiosub.html

assembled for 53.95, and a kit for 39.20. im just gonna stick with the pre-assembled package i believe

nice find!

did you check the power and consumption.  gonna have to make and or carry another battery pack to use it, "POWER SUPPLY: 10 to 15VDC / 300mA max." thats what it says...  still looks like a badass little thing. i might have to get one.. but lookes like more fun to build it..

Like most of the other peeps said.. if it came with independant LED's for both channel it'd be cool.. Since one of my mic's runs on average 2db below the other it'd be nice to have something "graphic" to even it out.

Anyone ordered or tried this out yet?  Could a 9v power the metering thing ya think?

V3 comparison I'm attempting tonight and...I now know better what you guys are going through!  Sheesh...a -3dB LED for each channel would've done the trick, I can't believe they only put in one LED.  Those bozos.  And yeah, the JB3 meters suck.  I'm sorry I ever questioned your collective intentions on this one!
Title: Re:Metering, was JB3 metering
Post by: Craig T on November 20, 2003, 02:03:58 PM
all I do is increase the gain in one channel unil the LED lights up, back off a bit until it stops and repeat for the other channel.  If it gets louder and the LED comes on again for more than a brief flicker, I back both channels down equally.  Seemed to work fine the few times I ran the ua5>PDA (poor meters like the JB3).
