I am hiring two Lectrosonics SMa transmitters with a SRa (?) Receiver. I tested everything out (good thing because of the first receiver output 2 failed). But now I test it again in a quiet invironment, and one of the two SMa's is giving a lot of noise. Also, everytime a -10 or -20 LED blinks a pop sound is audible. Is this device broken? I tried: Changing level, Frequency, Rolloff, replacing battery, replacing microphone, replacing antenna, switch mixer input, Check compatibility (can only switch between hbr and ifb). Help! Argh! I can't contact the company bacouse it's evening now here (Netherlands).

I planned on using an Ambient UMP-2 with a Lectro SMWB for boom. The setup basically works, but there is a whistling noise when using the SMWB. I guess it is neither the cable nor the power supply as I tested both with an older SMa, and there is no hiss. The noise is present on all 3 of my SMWBs. Did someone here encounter this or knows a workaround?

i have a venue receiver with a VRT installed (all current firmware) when i go to 'Detect' on the venue i get a '?' on this channel. its not the frame, it follows this specific VRT module.. now i can assign it to be block 20, which it says it is on the VRT, but the frame cannot detect it. anyone know why this is?? could it be a VRS module which might have been tagged accidentally a VRT??

With a properly wired cable for line input into the Lectro TX the TX cannot be attenuated enough to make it useable. The 302was set to factory default line output and the cable was wired as per Lectro with the line source feeding pin 5 on the TA5. A call to Lectro tech support came up with a solution of adding a 10k ohm resistor in series with the positive feed which dropped the "0" level of .775vac to .395vac from the 302which should be fine. Lectro tech thinks it's an impedence mismatch between the 302 & the 400a causing the problem. Anyone ever had the same type of issue with a 302 & a UM400a? Thanks, Eric

Looking for some advice so I can plug a mic to any line level only input; there are different settings out there.... Using 10kOhm & 100Ohm resistors seems to be one of the most common but I am not shure if it is the right choice for me Any help? Cheers!

Somebody over on Gearslutz just asked this question, so I thought I'd put up a list of a half-dozen discussions over the last few years on this subject... Some discussions on different techniques for micing dialogue in cars over on the JWSound Group: I think it would be nice to have a Frequently Asked Questions section so that when people ask "which microphone is best for this room?" or "what frequency will work in City X," we could just refer to them with a link. Or better yet, make sure they understand that they should check the FAQ section first rather than post a question that's been answered many times.

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 have been recruited by my kids' elementary school theatre director to help with their feedback problem... To start with, I have suggested they only use two of their four speakers, since volume is not an issue. Four speakers sending sound bouncing around the room seemed an obvious problem. This is a relatively small are, and is a multi-purpose room with linoleum floors. When it's full of people, the problem is less, of course, but they are having trouble rehearsing. I have angled the speaker so they are not pointed directly at the back wall. Their biggest problem is with their lavs. I installed a delay box between the mixer output and the amp, but it doesn't s…

Low-Temp Chart for Rechargeable Batteries Temp Fahrenheit 5°F 14°F 32°F 73°F 140°F Temp Centigrade -15°C -10°C 0°C 23°C 60°C Capacity Delivered Lithium-Ion rechargable 70% 90% 100% 95% Capacity Delivered Lead Acid 65% 85% This means if the ambient temperature is 14°F, the lithium Ion battery still delivers 70% of its capacity. If it’s rated for 7 hours use, then 70% of 7 hours is 4.9 hours. Always charge at room temperature. Blow hot air at ‘em. The manufacturer warns of explosions. The manufacturer recommends to charge under supervision only. Why not put the Battery on something that will not catch fire while charging: the bathtub, a t…

Hi all, Before Nomad officially arrives to Sg, I got myself a Zoom H1 because my Zoom H4n went robust!. Unfortunately for me, the line input doesn't seem to match with my SD 442 XLR - 10 or Line Outputs! The only output that works now with the H1 is the Tapes out on the 442. I know it has something that got to do with the Line Input on the H1 and XLR Output level because I managed to get the XLR outputs on my 302 to work after padding it down to -10 Line. any idea how do I go around solving it for the 442? Put some resistors in the 1/8 - 2 XLR cable that I had made maybe?

I have a feeling this might have been discussed here before, but I couldn't find it so here I go. As an example lets say you are using a 442 mixer going to a EX1 camera. The Mixer peaks at 20db, but the camera peaks at 12db. If you set your tone to 0db on the mixer and 0db on the camera, the camera audio will not mach to the mixer and will clip much earlier. At what db should the tone be set to on the camera to match correctly? And is there a formula to figure that out for other unmatched db situations? Nejc P

Hey guys, I'm totally stumped. I got the Remote Audio straight replacement cable since my cans were a bit old and one of the ears had gone out. I'm not the world's best solderer but here's what's now happening. Left channel goes to Left ear (as planned). Left AND Right channels go to Right ear instead of Right channel only. I can't figure out why the Left channel is getting to the right ear, full and clear. I tested with a couple different playback devices using youtube stereo test videos. I also put a stereo song in a DAW. Panned full L, I hear L in both ears, Panned full R, I hear R in Right ear, nothing in L ear. Panned center, I think I'm hearing L…

My apologies because this is likely a simple question but I'm very new to this: The following piece of equipment was damaged on set: Micron Transmitter (TX501, 211.0 MHz, 50Mw) The receiver that I have (that is not damaged) is as follows: Micron Receiver MDR 550 (range 198 MHz to 216 MHz) Do I have to replace it with the EXACT frequency of transmitter or can it be one that falls within that frequency range? Thank you so much for any advice/help! It is much appreciated!

I have this old Micron tx 501 with a Sony mic but as the Sony is so big to hide I think I would like to change it to a RODE one as can change the cable with those so I can use it with Micron with its own cable. Now you older professionals might remember how to connect this combination. Tried the same as with Sony and didn´t get it working so I put the Sony back. The Rode cable is a nightmare to solder with bad eyesight at least... As a retired sound guy this is more or less for hobby, but if someone can help I would be very thankfull! Matti

I have recently been doing some fairly simple sit down interviews with a bunch of ladies, who's voice could not be any quieter. I ask them to talk louder if possible but my request falls on deaf ears. The room we have been using is also not very quiet, AC constantly on, traffic outside ect.. So my question is: What would be the optimal mic for a boom pole for something like that? Right now I am using B6 for lav and the Schopes CMIT 5U for the shotgun. I was thinking maybe a Schopes capsule like the MK4? Any advice would be great. Thanks, Nejc P

Hey all, I'm curious what mixdown levels most (post-production) sound mixers use with films, particularly short films. I vaguely remember from college that our outputs should be peaking around -10 or -12dBFS at the most. However I think this must vary a lot depending on the application of the film and more confusion is added on what is an acceptable loudness, since peaks do not define loudness. Furthermore I suspect these levels would be inclined differently for web purposes. I've done a few sound mixes in the past that clients were happy with, following the above rule, however recently I've received a request to basically get the mixes peaking as loud as poss…

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!

Hey Everybody, Here's a sound clip of the issue - https://drive.google.com/file/d/1j72Oz6bbUYmnHS7TAKu_d5GZF0hkJJxP/view?usp=sharing I'm using a UMP-II with a UM400 transmitter and a MKH50. I'm getting a "boiling" or buzzing sound from the mic. My 416 works fine with this exact same set-up. I've connect the MKH50 to the UMP-II and then directly to my recorder and it sounds fine. I've tried putting a longer xlr between the MKH50 and the UMP-II and the problem remains. I've also tried a 200 series and G3 tx and the problem continued. I don't currently have another newer transmitter to test with but t…

MP3 - timecode in ID3 tag? I've googled pretty extensively to find some more information about this, and what seems to be the main reference site - ID3.org - seems to have puzzlingly been down since 2012? So I've not made any progress. Can anyone refer me to or know more information about where and how timecode is placed in an MP3 ID3 tag such that transcription houses can use it please? There seems to be a wide variety of ID3 tag readers and editors but timecode reference seems to be outside of thier scope. Anyone know of one that can read or edit the timecode reference please, I couldn't find one? I know BWFWidget Pro can create MP3's with timecode in the I…
