Talkback muted from microphone

PostThu Aug 17, 2017 1:45 pm

Hi, i've bought in the usa a 0.206" aviation connector plug for the microphone input for the TVS HD, soldered a XLR cable and connected a mic, but i have no sound from he mic, i don't know what i'm doing wrong, this is a gallery (8 pics) of the configuration, please advice me if it is something wrong:

your connector is mis-wired. try this...

XLR from mic
1-sheild wire
2-red wire
3-white wire

.206 Plug to TVS
tip-unconnected
ring - red wire
sleeve - white wire
insulate the shield wire on this end and leave unconnected

the TVS may also supply voltage to power the mic, a capacitor may be required inline to block this voltage for dynamic mic elements...

Hello Amin. The microphone input circuit is designed for an aviation electret microphone. Some external circuitry may be necessary to make other microphone types to work. The capacitor mentioned above is probably necessary as well.

i'm going to try this config to see, i have used a normal xlr mic, but the same results, tonight i'm going to test this config.

Hi Guys,

what do you depress on the ATEM TVS to talk to the Camera Converters?
in my case it is a ATEM TVS 4k.
