    Alexa Mini audio menu

    Maybe so, but it happened both with abox, as well as straight to the Lemo. Also, the camera owner said this is “just how it is with this camera”.

    Alexa Mini audio menu

    To clarify what I said above, I don't think it's a function, like on the Canon C300, where you can set channel 1 to go to both tracks. Rather it's the two channels bleeding across to each other. I mean, we are pushing two channels of line level signal into a single tiny little Lemo connector....

    Whatever Sound goes to the mini should be considered scratch/guide track. I have noticed when sending tone to ch1, that ch2 shows signal - even when only plugged into ch1, with level pulled all the way down on ch2.

    Comtek BST-25/216 on battery power?

    From Comtek Tech Support email: "Unfortunately, there is not an acceptable voltage range, and putting 16 volts into the unit does risk damaging it. It would be best to use a regulator to keep the power at 12 volts".

    For the Whisky drinkers

    Picked up this at the tax free shop at the airport in Stockholm on my way back to LA the other day. Just cracked it open, and it tastes quite lovely. Great smokiness!

    Whoa! Good to know. Thanks Ben. May I ask what regulator you use now?

    Comtek BST-25/216 on battery power?

    Thanks guys, much appreciated! JW, I agree - most manufacturers spec a range, and this is why it got me a little concerned. Yes JB, I will try calling them when I get a chance, to get their perspective and actual specs. I've also had nothing but a great experience calling Comtek in the past. It's great to hear first hand experience from the field though. Everyone here knows what a NP-L7S is, and that it can spit out upwards of 16v when fresh off the charger, then hovers in the 14.x range...

    Comtek BST-25/216 on battery power?

    What are you using out there for battery power with the base station? I've only used it with AC, but would be good to have an option handy at times when this is not a viable solution. The manual states "Power Requirements: 12 Volts DC, 300 mA max". It's not clear to me if this 12v requirement is such that one would need a regulator keeping it at precisely 12v when using a NP-L7S with a cup-to-4-pin XLRF, such as the one from PSC: http://www.locationsound.com/psc-fpscpsm-np1-4pxlrf-np-1-battery-cup-with-4-pin-female-xlr-3576 Anyone with experience doing this, please let us know. Thanks.

    Coming price change on SRa to SRb conversion

    I would strongly advice against this method, as it may result in both of you being shot by security - with a potato gun.

    Why AES camera feeds for prod. sound?

    In theory, AES would have some (minuscule?) benefit because it avoids the conversions D/A-A/D (mixer to Tx) and D/A-A/D (Rx to camera). Maybe just me, but the Sound is susceptible to everything that Wireless comes with anyway, and there’s no reliable way to monitor from the camera, therefore I view on-camera sound as "scratch feed" and for sync guide only. I guess if the Sound was recorded on camera only... and hard wired from the mixer, so I could monitor back from camera... Haha, sorry - maybe someone else can make a better argument in favor of this.

    In ear monitors for production sound

    Update to my post above: Having read comments here and elsewhere about how the Westone in-ears don't have the problems with cable noise, I started looking into this. Turns out they have one version with the same connector as the Shure 215. There is a slight difference - the connector is a little bit recessed. But I read about how others had made this work, and ordered a Westone cable. After carefully trimming back a tiny bit of the rubber around the connectors, they actually snapped in to my Shure ear-pieces just fine. Truth be told, that cable is definitely the best one I have tried so far (in terms of the cable noise). Might give this combo a shot on a job soon...

    Lectrosonics UCR100 - which transmitters will match?

    I can confirm that the UM400a will work. Check the manual for how to set it up in 100 mode.

    Sanken COS11-D vs SERVO

    Any time when using a newer model Lectro Tx (400a, SM series etc) with servo bias, and pretty obvious that reduced sensitivity would be for when there’s shouting or loud singing. Mic’ing guns, race cars, jet engines would be other examples...

    In ear monitors for production sound

    I have a pair of Etymotic, isolation is very good (especially with the foam tips which are basically just like ear plugs) and they sound great. Cable noise has prevented me from ever using these at work. Drives me nuts. I wish the manufacturers would make in-ear cables with a short portion of soft, coiled suspension next to the ear piece that would serve as “shock mounts”. I also have a pair of the shure 215, which are slightly better in terms of the cable noise. The part of the Cable that attaches to the ear piece is “moldable”, goes up-and-around the ear. This seems to help a bit with the cable rubbing noise. Sounds good. Isolation is good. I have used these for work a few times when it was practical. The thing that prevents me from using any of these more is the unplugging/plugging to be aware of what’s going on around me and people start talking not realizing I cannot hear them. With cans, popping one ear off, or even taking them off to put them down is a matter of a half-second to get them back on. Might just be a matter of getting used to doing this quick with the in-ears, but I feel like I’m messing around for a minute getting them situated in the ear, and getting the cable in place.
