Instead of observing the warning 120 days has past since this has last been posted in, I thought I'd keep it in here anyway.
Is anyone else using the
Naztech PB15000 to power your V3?
I bought a V3 a couple months ago and have done 7 shows using the Naztech. Pulling the opening act and headliner, I usually have at least 1/2 the batteries capacity left according to the battery indicators. I've been experiencing some issues ever since I've added the V3 to my chain (akg460/ck61>v3>R44 SPDIF/Analog), but I don't think it has to do with the V3 itself (it's at GD as we speak being tested).
After reading all the information about the power supply connection etc, I'm guessing when that is an issue, you would lose power to the V3 all together?
I ask that because my issue primarily has been the signal in both channels fades in both the SPDIF and analog feed after approximately 45 minutes to an hour and 12 minutes of run time. After the opening act (less than an hour) I'll either put the deck in record/pause mode or have shut everything down all together with the same result, that being, after the headliner comes on the channels fade to almost nothing in some cases approximately an hour in. Rather odd, in some instances, the signal has regained some power toward the encore of a 2 1/2 hour show.
I'm using a Lowpro Magnum 200 AW bag, stilts and initially (first 2 shows) had two Naztech batteries (btw set on 9v) slid between the R44 and V3 using dividers. Thinking this may be causing to much heat, which I thought may be weakening the signal from the V3, I moved the batteries to the side in their own separate compartment. Every time I run, I have the Lowpro unzipped with the straps buckled for the top and I hang the bag with one of those super large snap hooks usually on the fence rail etc, to leave plenty of room for air to circulate.
Other things I've done, changed cables, sent the mics to Richard Land for servicing, caps rebuilt, sent back for verification after continuing to have this issue. The 6th of 7 shows, the levels ran fine through the entire night (approx 4 hours) with only a very slight margin of difference between channels in both digi and analog. But then the very next night, things went haywire again and the fading was back to the point, by the encore I had nearly no signal. Things will run perfectly and near perfect levels in almost 4 hours of testing here in the house in a controlled environment and GD said their initial testing of 4 hours (playing music through the V3 on the bench) didn't produce anything abnormal.
My initial thoughts is heat being a culprit because in an air conditioned environment (running batteries) things seem fine. But though even as hot as it has been, inside the bag hasn't gotten like what I would consider super hot, I mean you can still touch it and like I said, I make sure it is well ventilated etc.
My second thought is maybe the Naztech power output weakens under the stress of heat and isn't sending enough power to the V3 possibly causing the signal output to drop?
Sorry for writing a book, I just wanted to try and cover it all and reach out to you all in hopes of finding this demon I've been chasing! Maybe I should have started a new thread? Thanks for any help or advice!
