Using Sanken CS-M1 as wireless boom

[Barbara]

Hey,

 

Has anyone used the Sanken CS-M1 as a wireless boom with the audio limited a10, and does it create a hum noise? I'm having problems with my sanken when I use it as a wireless boom with a Denecke PS-1A phantom power supply and a G3/G4 or Wisycom, and it doesn't send any signal, I just hear a loud hum noise. But when I connect the sanken directly into the recorder I can hear it loud and clear, even using the Denecke as phantom power and connecting it to the recorder I can hear it. Does anyone have any issues with this, or is the Sanken malfunctioning? Has anyone used it as a wireless boom with the audio limited a10, and does it work correctly?

Since you have confirmed that the Sanken works fine directly into your mixer, with or without the Denecke PS, I think you can conclude that those two are fine, and there is something down stream between the mic and the mixer. Possibly the wireless, but since two different brands have the same results - most likely the cable between the receiver and mixer. Provided that your wireless systems are set up correctly, of course.

Hi,

I also use the PS-1A to power my mics. Works fine with Mkh60 & Km184-185, but doesn't with CS-M1. I have the same loud hum noise that you experience without any signal. I assume the Sanken isn't compatible with the Denecke.

Try a phase reverse lead into denecke..

Thank you.Yeah, I'm going to try it now with a Lectrosonics plug on and see if it works. Thank you all

Does anyone knows if it works with the audio limited A10?

My CS-M1 works fine with Lectrosonics HMA plug-on

I'm really interested in this because I'm planning to buy the Sanken CS-M1 mic to use with the deity plug-in transmitter.

It worked with the lectrosonics plug in. Its weird it doesn't work with the G3 or Wisycom transmitter and denecke

[r.paterson]

I suspects its the unbalancing out of the denecke into the g3 or wysi..the lectro plug in is psuedo balanced..i have and i know others have added a 200 ohm 1:1 transformer on the output of the denecke its simple to add and thas solves a multitude of issues and alows an unbalnced output without issues. Neutrik do a 200ohn 1:1 transformer which is a perfect fit in the denecke

[r.paterson]

The other thing to note is the denecle 48v passes the 48v thru to the output so even unbalanced you are hitting g3 or wysi with 48v hence putting isolating transformer on the output of the denecke.

I know it's already been posted, but I'll also confirm that it works just fine with Lectro plug-on Tx's(UH400A).

I asked the manufacturer and they wrote: 

"The PS-1A and PS-2 output a quick voltage spike when the battery is first inserted into the unit. Once it is on, there is no DC at the output. If you are concerned about damaging your Tx, you will have to remember to power on the power supply prior to connecting it to your Tx. "

Just to add: I measured both PS-1 and PS-1A outputs and it can output as much as 25V for a couple of seconds. Fitting an output transformer is ABSOLUTELY necessary!

And i did just that inserted Neutrik NTE-1, thanks to mr Paterson here,ouput is 0v. All good
