How does a switching XLR receptacle work?

I'm looking at the datasheet for a 'switching' XLR/Jack combo receptacle (NCJ10FI-V) but am unsure about how the switching works. Am I correctly assuming that S and SN form a normally open switch? What if I want a microcontroller to be able to read…

Why is this dynamic microphone grounded / wired with more than the two pins? is it important?

I am rewiring a dynamic microphone that does not require any phantom power (also wicked simple no off / on), and I noticed, when I only wire the two wires to two of the three pins it still works and seems to sound great. When I have taken apart…

Balanced Mono XLR output to Unbalanced Stereo Input

I have an Allen & Heath ZED-10 mixer with a balanced XLR output. All signals coming into this mixer are mono and therefore we were going to use a single balanced mono XLR main output (Left channel). This output is going to a camera 75ft away via…

How to buffer balanced (XLR) audio signal while forwarding phantom power

Background: I have a condenser microphone, which requires +48V phantom power from my mixing desk. The microphone has a source impedance of "<200 Ohm" as per manufacturer. As you may recall, phantom power is delivered over both the "+" and "-" wires…

Add 5V bias power to use an electret microphone with XLR audio interface

I recently acquired an audio interface (Behringer UMC22) and, since it's quite a bit better than my motherboard, I'd like to connect my modmic 4 to the XLR mic input. The interface has phantom power available, but it's either off, or 48V, which is…

Short XLR connections via XLR 'cables' or separate wires?

I'm intending to create a so called patch box (for audio signals), with 16 channels. Each channel has 2 female XLR and 2 male XLR connectors which are tied together (all 3 wires). The distance between 3 of the connections is about 2-4 inches, the…

Soldering XLR Cables together

I'm aware that the structure of a balanced cable is an integral part of maintaining signal quality. If I was to solder two XLR cables together in an effort to make one longer XLR lead, what would be the potential consequences? Would the it lead to a…
