Does anyone know; if a monitor only has HD/SDI input, will it be able to receive a 3G SDI signal? I may be purchasing a used Marshall dual monitor that has only HD/SDI but most likely it'll be plugged to the output of a teradek bolt receiver. Cheers! pablo

Whilst perusing the Phonak web site I tried this simple hearing test There is no real scoring, just advice as to whether you may need to see a loss specialist. I tested with the MacBook Pro open speakers set to a couple of clicks below mid-volume. I believe I heard all the words except one– I was in my kitchen and the refrigerator compressor clicked on precisely when one was spoken. http://www.phonak.com/us/b2c/en/hearing/recognizing_hearingloss/hearingtest.html

I have a schoeps 641 and an mkh50 that I use with a trx 743. I’ve noticed that when the boom pole gets jostled, there’s a small burst of static and it sounds the same on both mics. I’ve isolated it to the mics and I wanted to see what might be causing this and what I could do to fix this?

Hoping someone can help me with this. I'm looking at changing the settings on the limiter out of my Audio Developments Board. The manual mentioned two things about setting the limiter (outside of attack and release times) - "Biasing and Threshold." The term Biasing is not something I understand in this context. The manual reads like this: "Biasing and threshold are adjusted as follows: VR1 biases the limiter circuit to the point of correct operation and VR2 sets the threshold." Is Biasing at all related to "make up gain" that is offered on many compressors? Thanks for any knowledge, -Greg-

Hi all, Did some search and couldn t come up with any suitable answer. Video monitoring creates a delay between sound and image that makes judging proper lipsync on music video challenging when looking at monitor. I ve used simple technique to guesstimate delay with a slate listening to my erx ifb but i d like to have a way to have a proper time measurement? Filming fs700 hdmi to hdmi to sony monitor guesstimate gives me around 80ms. Any ideas? Cheers!

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

Again, mad physicist exploring TC world here. 😁 Is HDMI timecode LTC and is it using Consumer Electronics Control (CEC) pin bus? Or maybe Pin 17? I understand timecode over HDMI is a hack introduced by Atomos almost ten years ago and then adopted by many manufacturers but can't find any technical details about it... any pointer? [EDIT: or is it SONY with the FS100? as discussed here on jwsd] Thanks in advance... Fun fact: looking around I learned Atomos under CEO J. Young was a shitty place to work at. PS: I'm referring to pin 17 as "Utility/HEAC+" signal, defined in HDMI 1.4+ version. This signal moves from pin …

So you look at the frequency map on lectrosonics and sennheiser... you see there's a TV channel with 15kw tower in your frequency, but it's 60 miles away. Let's say you have a lectro set with one frequency in the middle of that band. Will it be crystal clear or will you only hear that TV station through the receiver? How do you know? Normally I look for channels in a "vacant" block... but what's the cutoff? Is there a hard number here? Can you expect clean audio even if you're in the middle of a weak TV channel? I've worked with 411 many times and rarely had to seek out a new channel for clear audio... Let's say I find a bargain 195d for backup, but the frequenc…

Hi everyone, Having some issues that I've never encountered before. Your advice is appreciate! I'm recording onto a Fostex DV824 as primary and 744t as backup. Shooting 35mm. Post wants sound at 24 ND, 48.048 K. The DV824 doesn't record at 48.048, so I have set it to record at 48K, then pulling it up +.1%. Here is the issue: Post is saying the TC displayed on slates and the TC being stamped on metadata are totally off, with no consistency. Not a drift. Sometimes is 30 seconds off, sometimes 90. On set, the slates match my decks all day long. I can guarantee the slates and recorders are sync, but I don't know whats being stamped as metadata on the disc. …

Well, long story short, I am having trouble exporting sound files from a Korg D3200 digital recorder to my macbook. The files include a 1.4 gig 16 bit (44.1 khz) file, and the other is 24 bit (48 khz) and stands at about 4.8 gigs. Now i have two main problems, the first is that the transfer space i have available on the recording station is only 4 gigs, and i can't transfer the larger of the two files to my computer via USB. I need some way to either cut down on the track, or enlarge the transfer space without ruining or deleting what i have. The second came when i transferred over the smaller of the two files, but found it was a .DBK file, which i found out, after…

I have considered getting 1 Lav for a noisy location with a presenter direct to camera where the lav can be visible, perhaps a cardiod pattern lav but only if the presenter is directly addressing the camera without a sweeping arm gesture and head turn. After this week I am considering something else: I recently had to use the VT500 single lav in a supermarket using Lectro 411 unit. Background ambience faded way to the background much more so than many other lavs I've used. And later that day, two separate provided lav models on 2 talent on-camera together using Lectro 411 units. -A white Voice Technologies VT500 -Lav Mic which was for a broadcast TV talkshow segm…

Hi all, I am heading to the U.S for a doco shoot and am planning on taking my block 21 wireless mics and block 22 camera hop (SR5 Rx + 2 LMa Tx). I will have scanning ability on both blocks. At this stage we will be shooting in LA, San Antonio, Toronto, and Chicago. I understand that 21 is ok but 22 not as good in places like LA. As my block 22 is primarily my camera hop and both TX and RX will have good line of sight and not be far apart much of the time that this should still be ok... Any thoughts or feedback appreciated (I will be running a back up recording of all audio if the link does throws a wobbly to be safe). Thanks, Chris.

Hi all, I need to wire a PTT comms type mic to a TA5F so it will work with a UM200C Tx, I have done this before so know it works but the mic broke and the connector has gone awol and of course I never wrote down the wiring configuration! The mic is from a standard onset RT and has 3 wires, red, green and copper. Has anyone else has done this (and written down the wiring info!) last time I did it I'm pretty sure I didn't use any resistors but it maybe had 1 capacitor in the mix somewhere but maybe not... Thanks! Chris.

Hi all, I just miced up someone today with the above system and very random, without a mic plugged in, I hear a very random popping. Almost like a cable popping but softer and not scratchy. The system work perfect the last time I used it. My experience with troubleshooting wireless is not much. So any help would be great. I swapped batts, antenna and jiggled it violently with no specific result. Very random and not caused by vibration. Thanks for your suggestions. Scott

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?
