GearHead917 Posted October 30, 2014 Report Share Posted October 30, 2014 Hello, this is my first post but I need some help. I'm on a shoot with a Canon c300 and I am using a lectrosonics srb wireless receiver for my hop. I get an email from the editor telling me that the audio sounds low/bad. I have been sending audio from my talents mic to bothe channels on the c300 camera. It seems that this is causing a cross phase problem. When you switch from sending audio to chanel one to bothe channels. You'll see the audio levels on the camera drop by half. Has anyone else had this problem?

Peter Wong Posted October 30, 2014 Report Share Posted October 30, 2014 Hi gearhead917 In the srb menus there's a phase option. Check that first. Peter Quote Link to comment Share on other sites More sharing options...

Jay Rose Posted October 30, 2014 Report Share Posted October 30, 2014 How are you splitting the mic to two channels? Within the camera, or with your wiring? Quote Link to comment Share on other sites More sharing options...

GearHead917 Posted October 30, 2014 Author Report Share Posted October 30, 2014 I am send it through my 664. You set it to send to bothe the left and right. Also, I talked to lectrosonics today and they say that you need to have the higher frequency on Ch1 and the lower to Ch2. Which is the reverse of what you do with SRa. They say that this could be the cause. What do you think? Quote Link to comment Share on other sites More sharing options...
GearHead917 Posted October 30, 2014 Author Report Share Posted October 30, 2014 I will try different cable also. Thanks. Quote Link to comment Share on other sites More sharing options...
macrecorder Posted October 30, 2014 Report Share Posted October 30, 2014 Are you sure the C300 is set up right? Could it be you are mixing and phasing both channels down to one across both? That's what it sounds like. Quote Link to comment Share on other sites More sharing options...
JDirckze Posted October 30, 2014 Report Share Posted October 30, 2014 Does sound strange. In the SRb what is the MIXMODE set to? I'm curious about the advice Lectro has told you in regards to keeping CH1 on SRb higher than CH2 also. I too thought CH1 should be lower...

GearHead917 Posted October 31, 2014 Author Report Share Posted October 31, 2014 Alright the inside story is that I got new cables and removed the ground on pin one. *I changed the highest frequency to channel one and the lowest to channel 2. *I also checked the Frequency chart for inter modulation. * Also my SRb is also being powered by batteries and not the power distribution on the camera. The reason being that Hawk wood v mount batter distribution. "notes that it can create a ground loop that causes a hum/buzz or on wireless. Everything is working fine now. Thanks for the responses guys. I really appreciate it! Abe Quote Link to comment Share on other sites More sharing options...
Jon Gilbert Posted October 31, 2014 Report Share Posted October 31, 2014 I'm surprised you didn't hear any of this on your tests before the shoot? Quote Link to comment Share on other sites More sharing options...
