Hey all, I want to send 5 volts continuously down the "positive" leg of a Canare Star Quad cable. I'm assuming that is completely fine as Phantom power would be sending 12-48 volts. Phantom Power sends a continuous charge at a higher voltage than I'm looking to do, so I should be fine...? Maybe the info is in front of my face when I check out the Canare Star Quad specs: http://www.canare.com/ProductItemDisplay.aspx?productItemID=53 But all I see is that Star Quad has a max voltage of 500V AC and at only 1 minute. I want to continuously send 5 Volts of DC. This is for a remote control, but I would like to use Star Quad cables so I don't need a dedicated c…

My sister was in town and came with me to a rental house. She was looking at the labels and names on some item and commented that if she had just heard some of the names without seeing the items, she would assume she was in a hunting lodge. I thought it would be interesting to compile a list somewhat specific to our industry with how we define them. butt plug - xlr plug on transmitter dead cat/ dead wombat - "hairy" cover for a wind blimp wire - refers to lavalier plus transmitter. as in "wire the talent" shotgun - supercardioid microphone MOS - mixer outside smoking, Mit out sound, minus/missing optical stripe, etc. *edit - I did a search after posting and c…

What kind of audible artifacts, if any, might appear if I wanted to record three separate ISO tracks on a recorder like Pix 240 using two different AES3 input pairs that share the same sampling depth and approximately same sampling frequency (48Khz/24bit), but are not synced to the same word clock? As a practical example, let's say there was a boom mic connected to input 1 via a MixPre-D and a Sony dual channel DWX series digital wireless microphone receiver connected to input 2. The Sony receiver has a word clock input, but MixPre-D doesn't have one. Let's say there are no word clock sync cables connected between the devices at all. It is difficult for me to un…

Hi, might lend myself a small gig that involves shooting with the Alexa. From what I heard from many, it is a double-system workflow shooting with it. Since the budget does not justify in investing myself with a Nomad, I'm just wondering if the Fostex FR2 with Timecode option will be able to work with Alexa, timecode compatiability wise. Much advise is needed. Thanks a lot!

Hi there, I have got a new 788t with cl-8. How can I listen in post fader from my hp? When I use the 788T in post-fader, also if all the cl-8's faders are -∞ I listen the armed tracks. Why? I would like to listen only the tracks that I open from the cl-8. Is it possible?? Thank you

I know this is possible and tried searching for it, but was unable to find any details. I was interested in using some of my Sennheiser's as an IFB since my Comteks got stolen. I'm using the 552 now and I'm feeding the transmitter from the mono mic out of the mixer. I'm just not sure on the setup for the receiver. What is the setup for using headphones with the receiver? Is it useful to have an inline (manual) volume adjustment on the headphones? Are there specific settings that need to be set on the receiver? Best, Palmer

Have just come across an old Soundcraft LM1 mixer that I'd like to dust down and get working properly again. If anyone is familiar with this mixer i'd like to know how to adjust the 1khz tone generator level so it hits 4ppm/0dbu when the master L-R is up to 0. At the moment tone is lining up between 4.5-6PPM when I'm adjusting the needle sensitivity with a tweaker (doesn't go any lower). Thanks in advance!

I need some help/advice regarding my Nagra III. I made a DIY power supply from a wall wart (12VDC @ 1A) using a 6 pin DIN and pins 2 and 5 on the accessory connector. Positive is earth/ground. Works almost perfect except for rewind. I've read the manual and other relevant posts here and elsewhere but can't figure this out. Again, playback, record, line in/out and the XLR all work as they should. I have the function selector switch set to EXT and when I turn it to either playback option and turn the tape transport control knob to the 'ON' position it plays no issue. However when I turn the On/Off knob to the left to disengag…

Hope there is someone that might be able to help with this... I'm doing sound on a multicam live event shoot this week. The record and edit frame rate is set to 23.976FPS (NDF) and thus I will be recording at 48kHz. There will be a sequence that will require playback and I am intending to send timecode from my audio system to each camera using wireless link. I will probably also try and get a smart slate on set so that there is at least some visual representation of the timecode. Unfortunately my audio playback system doesn't support 23.976ND fps - the lowest timecode rate it will go to is 24fps. This means I can't generate timecode at the right rate for pl…

Hello everyone, there is a problem with my SMa transmitter, when the audio level is less than 15, noise like "boiling" comes along with the voice, the problem appears suddenly, sometimes it helps to pull out lavalier microphone and insert it back, maybe someone else had such a problem?

Good day my fellow sound peeps. Just a question.... I usually use the NP-F970 lithium batteries on my SRb receiver and it lasts a few days. Bought a NP-F550 today and just want to know what the average hours you guys get out of it?Or should I rather ask,at what voltage does the SRb switches off,if the battery runs flat? Thank you in advance

i'm hoping someone will help me out to understand the difference (if there is a difference) when using an older SD mixpre which has outputs that are impedance balanced, vs. an newer mixpre that has active balanced outputs when using it as a front end to feed signal into ch 3/4 of a 744T. i've got a few other questions: are there differences in quality, level, rf/interference rejection or other? is active-balanced and balanced the same thing? when going through an xlr how does impedance balanced avoid interference by having only one voltage line when compared to balanced that has 2 lines? i've read the paper on the differences (http://www.sounddevi…

Hello to all of you @JWSOUND It's good to finally be here. I have a question regarding Zaxcom Maxx recorder issue. I've already contacted Zaxcom and Ambient regarding the issue and the good people from Ambient told me that i can send Maxx for service/repair but i should also ask the question here as the nature of issues I'm going through is really weird. Never explained issue to Zaxcom, just asked about the possibility of service in Europe. I'll try to describe the issue the best i can. The other day i ran out of batteries (hawk woods np50) during recording session. At the moment i wasn't close to the recorder but when i came ba…

Hi, I am trying to split the tapeout of my 302 to- -1 stereo output to feed a backup recorder and -1 mono output to feed a Sennheiser G2 (used as an IFB feed) When I mono one of the leads, (using an adapter or direct wiring) it mono's both leads. Does anyone know of a workaround for this? Thanks -Jason

Hey everyone, This is my first post on this forum so hopefully this is the right place to post this. If not, let me know. I'm excited to have found this online community and I've already learned a ton from reading through the forum. I'm having a weird issue with my Zaxcom Maxx and RX200 and wondered if anyone had any thoughts on how to resolve the issue. Here's what's going on. Zaxcom Maxx with built in transmitter (Block 23) sending audio and timecode to a brand new RX200. It locks signal and works perfectly as long as the Maxx is being powered by the power supply or internal AA batteries but as soon as I plug in an external battery distribu…

I am trying to find a way to work with true 24P timebase using SD664 as the sound recorder and a PIX240 mounted on a Scarlet-X to record 24P Quicktime proxy files. PIX240 is fed with a scratch track via a Lectrosonics SRb in a Ambient Vslot adapter. I am outputting 1080p24 genlock signal from PIX 240 to a RED Scarlet-X and timecode as well. Video File resolution rate on PIX 240 is set to 1080p24/23.976. Sync Out is set to 24P. Timecode is in Freerun mode. Project time base on the Scarlet is set to 24 and SDI output is set to 24hz. Everything works OK as long as the Scarlet-X powered up and feeds the PIX 240 with a 24hz SDI signal. However, the instant I turn the cam…

10 Statements on Condenser Microphones vs. Dynamic Microphones By audio specialist Eddy B. Brixen www.dpamicrophones.com The topic of discussion on the difference between dynamic microphones and condenser microphones is never ending. That’s fine, we don’t want it to end, rather, we want to add to the discussion and further enlighten readers a little…First of all, we must clarify a few things: The difference between dynamic microphones and condenser microphones is all about two different transducer principles. In other words, it has nothing to do with the directional characteristics of the microphones. You cannot ask: ‘What kind of directional characteristic do…

I have just read this very clear paper on SD website about the 32 bit float resolution, and... I am blown away. 1528 dB of dynamic range, a headroom of 770 dBFS ABOVE our standard 0dBFS !! I understand now why the MixPre series is so popular amongst sound designers. https://www.sounddevices.com/32-bit-float-files-explained/ But now comes to mind an obsessive question: if gear designers like SD and more are capable of creating machines able to record files in 32bit float resolution, why have they not implemented it in their pro range recorders (like the 8 series for SD) ???!? Anyone capable to clear the mystery for me? Thanks Fred PS: I …

Fine people of the internet I pose this scenario to you: I own a MOTU Traveler MK1, not MK3. It claims it will "resolve" to SMPTE via any audio input and send out SMPTE via any output. The software it ships with, the MOTU Firewire SMPTE console, controls all of the SMPTE options as you'd imagine. The frame rate selection does not include 23.98 fps but only 24, 25, 29.97 DF/NDF or 30 DF/NDF. Digital Performer 5 also has this same limitation as does my older version of Nuendo. I also own a 664. I have jammed the Traveler from my 664 at 23.98 fps and it seems to hold sync for an hour or so in my brief test when the Traveler is set for true 24 fps SMPTE. I have ye…

I have several AKG blue line mic capsules and power modules and I'm running into an issue with my ck93 hypercardioid capsule. It loosened up, and when I screw it back together (see the 3 pieces in the pictures below) the signal becomes either very weak and hissy, or highly distorted noise. Wiring/soldering are not my forte, but I am led to believe that the three pieces are misaligned with one another. Does anyone know if this could be the case, and if so, what is the proper way to align/fix everything? Or could it be something else? I had the same problem with another 93 capsule and I somehow miraculously managed to get it to work again. I'm not having the same luck …
