I think the answer is here but I'm too tired to read it tonight.... I'll look at it tomorrow.... http://line6.com/support/topic/8955-close-to-an-xd-v75tr-purchase-quick-question/

I found this too but I'm not sure if it answers the same issue or not.... http://line6.com/support/topic/7389-input-impedance-tbp12-beltpack-when-pin-4-tied-to-pin-3/

I found this but it doesn't really answer the question.... I read something about using different adapters and sometimes the wiring needs to be changed or different resistors used..... I would prefer it to just be plug and play with no mods.... http://line6.com/supportarchivenew/thread/91163

Hi, I'm looking at getting the XD-V75 receiver and the V75-BP transmitter. I'm also looking at the Rode Lav with the Rode Micon 3 adapter for Shure belt pack transmitters, It says it will work with the Shure ULX, PGX transmitters which are TAF4. If this adapter will work for the Shure TAF4 transmitters.... will it also or not work with the Line 6 V75-BP transmitter which is also a TAF4 connection.... I have an email into Rode as well but thought to ask here too..... Thanks, Bob

Are all the fans being replaced in store inventory or just as requests of purchasers....? I'm going to be getting an L2T and didn't know if I should just get it now or wait for the existing inventory to have there fans replaced.

Found the answer... "Wired lavalier microphones work on phantom power; the microphone capsule is attached to a small tubular power supply that terminates in a three-pin XLR connection. Wireless mics, on the other hand, need internal batteries that may last anywhere from 2-7 hours." So any setup that calls for a belt preamp.. has the mic connecting to the preamp on the belt... then another cable running from the preamp back to whatever you are plugging in to. That sort of defeats the purpose of having unrestricted mobility. So for me wireless is the way to go...

I was looking at some lav mic setups and noticed on a few that they plugged into a belt held preamp that would run on between 11 and 48 volts. In that situation, where is that power being derived from? Is that telling me that that is necessarily a wired system, so there would be a cable attaching to the preamp on the belt? So does that mean that any setup that has a preamp on the belt that the lav mic plugs into is a wired system not a wireless system?

Oh, one other question. Is it a problem if the transmitter is covered by a suit jacket. I mean having it on the belt and just that a suit jacket is covering it. Total distance from transmitter to receiver is no more than 20 feet with no other obstructions between the xmitter and rcvr.

Thank you for that. I liked the idea of using a Lav mic just because its out of the way visually. With the headset, its sort of obviously there and maybe a bit of a distration for the audience. As far as the room size.... no more than 100 people. It would be your standard breakout session room in a hotel scenario maybe 30x40 or 30x50. That would be about a 12 foot ceiling or less. The amplification would be whatever one L2T is putting out. No other sound like music would be going on. No monitors would be used. Ok, so definitely a cardioid is out and an omni is a maybe. Honestly I would probably end up getting the omni lav and if it didn't work out then get a headset if I had to. And I'll nix the idea of warming up the audio with a preamp. .... your recommendation sounds like it would be going in the direction of..... "don't worry about the headset being visible to the audience, just get one. For what you want to do its all about simplicity and working. The headset will give you that." Allright, I'll start looking at headsets, too. I'm not in any hurry so I have time to investigate. Thanks, Bob

I have an HD500 that I use with my regular amp. I'm about 80% of the way towards making the decision to get a L2t to use with the 500. I'm also currently wired from my guitar into the HD500. I recently started ToastMasters public speaking club. Suddenly I'm realizing I would have a whole new reason to get a L2t. I see mostly using a lavellier mic for doing presentations using the L2t for reinforcement. If I get a mic that has a TA-4 mini-XLR, is it just a matter of getting a XD-V75TR bodypack system and I'm done? XLR from the receiver to the L2t and that's it? Would I need anything between the receiver and the L2t? A preamp for a little more gain? If I don't need a preamp, is there any issue if I put a coloring preamp like a Warm Audio there just to warm things up a bit? And a quick question on lav mics... It would seem that a super cardioid would be the way to go, but I am reading that an omni directional is better for a lav mic. Wouldn't I want the mic just picking up from my mouth and not all around me as with an omni? Thanks.

I just remembered the L2t has an XLR thru out.... so if I need to run a line to FOH I could just come off of that ... correct? So if that is the case it would be HD500 set to combo power amp and a 1/4" L out to the amps effects return... and the L6 link connecting to the L2T.... and then the XLR thru out on the L2t connecting to FOH if needed..... So then it just gets down to ... can I have the HD500 set to Combo Power amp for a connection to my amp effect return and the L6 running from the 500 to the L2t running concurrently....?

I'm using an HD500 with a Blackstar HT5 amp with effects loop. Had the amp for a while as a first amp and there is an upgrade in the future. This is what I am thinking of a potential future setup. HD500 L mono out to effects return. Set the output for combo power amp and the line level/amp swtich to line level. Get a new L2t and run the L6 link from the HD500 to the L2t L6 port. Just with that setup, will I get output out of both my amp and the L2t at the same time? At that point is there a way to get a feed to the FOH using the balanced XLR outs on the HD500....? The goal would be to have the amp, l2t and a FOH speaker all on at the same time. On one of the past posts I read that the output is a global command. So if I set the output mode to combo power amp... then there is no way to set the XLR out (which I read is always a mic level signal regardless of any settings) ... to what it would typically be for a FOH connection... Studio DIrect. So in this configuration it looks like I wouldn't be able to use the XLR out as a front of house connection... If there is a new amp purchase in the future .. then the DT25 which has the XLR direct out would solve this... right? If I did get a DT25... then could I just connect the HD500 L6 to the DT25 and the L6 from the DT25 to the L6 on the L2t..... and for the FOH connection use either the 1/4 or XLR outs on the 500 set as studio direct? OR, would I need to use the DT25 direct out for this.... so all the HD500 would be doing in this case is L6 and the DT25 would be the connection to the FOH. I guess the question there is ... can I use the L6 link on the HD500 and still configure the "outs" as a studio direct connection ... or does using the L6 prevent that configuration....? Thanks.

Thank you for all of that. I was going through my pedals and realized the Joe Meek Floor Q compressor/preamp pedal has an input impedance of 6.8Mg ohms. The nice thing is you can turn the compressor function off if you want and just use the preamp function which gives a clean 20db, from a class A circuit. So worse case I can use the 6,8Mg ohm input on the compressor with a little clean bump from the preamp to get it into the HD500. But is sounds like I don't need it anyway! I spent days researching this. I did get an answer back from Radial .... "Hi Bob, any device that has a 10meg input impedance will work with a piezo pick up."

Is there an amplifier designed for your pickup? Sorry I didn't answer this... The Electric Violin Shop sells acoustic amps for the violins they sell... which is frustrating because most or all of them don't list their input impedance in their specs. The LR Baggs Venue DI Acoustic Guitar Preamp lists its input impedance as 10mg ohms which is the same as the Realist pickup. So that would be a 1:1 impedance ratio... which goes against the convention of the upstream device having a much higher impedance. Ultimately what I want to do is to use the violin with the HD500 going into my amp out one output of the POD and use the other output and go into an L2t. If I have to get a DI box for the impedance that's fine.... What Im not understanding is the stated best practice with regards to lower impedance to higher impedance,... the stated impedance of the Realist pickup at 10mg ohms,..... and the stated impedance values in all these upstream devices whether it be the POD, Radials DI boxes, LR Baggs .. or whatever... because I'm left with a 10mg pickup impedance going into a 10mg impedance or lower upstream device .... and that flies in the face of everything I'm reading about what the ratio should be.

http://www.electricviolinshop.com/violins/realist-violins/realist-violin-rv5pe-shadow-3653.html http://www.davidgage.com/store/product_info.php?cPath=21&products_id=30 "The output level directly from the pickup is unusually high, and as a result the signal to noise ratio is also very high, so no pre-amp or other active, battery powered gear is necessary. Just plug it in! The copper foil sandwich construction is the third key element in the system. It provides total shielding to eliminate hum from light fixtures and other electrical or radio interference. It is flexible enough to conform to the curve of the top of the instrument, so that the full pressure of the bridge is concentrated evenly onto the piezo surface." I think this is where I'm getting confused... Even if the signal has been bumped up... its stil rated at 10mg ohms and from everything I'm reading says that the device you are plugging into has to be a significantly higher impedance to allow for good frequency transfer... if there is a mismatch it will roll off the high frequencies... ..... which gets back to the POD... there is a 1mg and a 3.5mg ohm setting.... (along with all the other lower settings and "auto") None of these settings come close to the 10mg impedance of the violins pickup... There was a response that the POD can handle any input... but if the port on the POD does not adapt to the equipment as far as an impedance value... then are we saying that the impedance settings in the POD don't really change the impedance but rather "model" the sound differently for each setting and that is what lets the user dial in the sound that they want? If that is the case that's fine... I'm just having problems understanding... If that is the case then there is still an impedance mismatch ... but it is removed from the perception of the listener because now its wrapped up in the modelling.... (?) I have to put a call in to Realist because if they would just say that their website was a misprint and the impedance of the pickup is 1mg ohms and not 10mg ohms that would clear up a lot of my confusion. Then using the 3.5mg ohm setting on the POD would make sense to me... 1mg ohms pickup : 3.5mg ohms upstream device (POD). Thanks.

The piezo in the violin I'm looking at is 10Mg ohms. If I need a 10:1 impedance ratio I would need to plug into something that had a rated impedance of 100Mg ohms if in fact I had to have a 10:1 ratio... The higher end DI boxes from Radial offer 4mg and 10mg. So either there is no box on the market that offers 100MG impedance.... OR ... I really don't need a 10:1 ratio and and it would work fine with a 1:1 ratio.... Radial makes a big deal about this new Firefly DI at 4mb ohms impedance being able to handle all types of acoustic intruments ... specificially piezo transducers..... thus my confusion...

So all this I'm reading about having to provide the proper load to the piezo pickup and needing a DI box with 10Mg ohm impedance... all of that goes out the window if because the "auto" setting can determine the load required and provide it?

Thank you! I forgot to mention that I have a HD500. I posted a question on the HD500 thread inquiring as to whether I can bring the electric violin in to the 500 on the aux port and set the patch for 3.5Mg ohms... Subsequently I found some posts on the "fiddle forum" where somebody was using the 500 with the violin in live settings and he said it was working great. Maybe I don't even need a DI box, maybe I had the solution right here all along... I have to go back to that forum and investigate the particulars...

Hi, I'm in the beginnings of researching and maybe getting an electric violin. It has a Realist pickup with a stated impedance of 10M ohms. The last few days I've been reading about needing a DI box to insure proper loading of the pickup. I'm a bit confused because the DI boxes specifically targeted towards piezo pickups makes a big deal about the input impedance of the DI being 4 or 10Mg. ohms. Yet this pickup says its 10M ohms. I thought the input impedance of the DI had to be significantly higher than the piezo that was connecting to it....? It also seems that it's not an exact science with a lot of trial and error. I just like to know what I'm going to be potentially dealing with as far as what's needed. I have a guitar,HD500 to amp effects loop setup now and it works great.... just looking to get into the violin. I just remembered that the HD500 has the 3.5Mg Ohm setting available. What are the chances that I could just plug the violin into the aux in port and configure a patch to be 3.5Mg ohms. If these DI boxes are being sold as a solution for a electric violin and are (for the most part) providing 4Mg Ohms, maybe I don't event need a DI... just use the aux in port with an acoustic setting and go from there... (?) Thanks,. Bob

The L2T has an input impedence of 100 kΩ balanced. I'm looking at an Electric Violin with a Realist pickup which according to the website the impedence is 10 mega ohms. (not sure if that means that's what it is... or that's what it wants to be plugged into.) It looks like I'm going to need a DI box to get the impedence higher to present to the piezo pickup as its a high impedence device and is looking for a higher impedence to go in to. I can get a box with just the impedence feature or get one that does the impedence and also acts as a preamp as well. I guess the real question is can I just get away with a box to do the impedence and then plug that into the L2t and the L2t would handle the pre amp and amp function.... or do I need a separate pre amp before the L2t? Thanks, Bob
