EWI MBQB Premium Pro Quad dual twisted pair Microphone Cable – black coated & gold plated Female XLR to Male XLR connectors, black 10 feet (3.05 metres).

“Quad” mic cables are often preferred by professionals for their enhanced noise rejection and reliability due to the redundancy of the paired wiring. Instead of only having two conductors and a shield, like regular mic cables, dual twisted pair mic cables such as these actually have four conductors and a shield. There are two conductors wired to each of the signal connectors (pins 2 and 3). Therefore, pin 2 and pin 3 have two wires each attached, with one wire from each pin paired and twisted the length of the conductor with the wires from the other hot pin

The theory is that twisting each wire the length of the conductor with a wire from the other pin allows any noise that is induced in one wire to be induced in a paired wire from the other hot pin. Since the induced noise in both conductors will hit the transformer at the same time, the two signals will cancel, and the noise will not be transferred down the signal chain. Besides all of that, since there are two conductors for each signal, if one wire fails, the cord will still work (maybe a little noisier, but it will still function)!

The 4 ea. 22 gauge signal conductors are extremely high purity 99.98% annealed copper. The braided shield is also tinned 99.98% copper tightly braided to give 98% coverage, which is some of the highest braid coverage available.

The Super Flexible Innocuous Neoprene PVC (SFIN PVC) resists tangles and stays flexible yet extremely durable over a wide range of temperatures.

The MBQB series are stock equipped with EWI ES3FB and ES3MB XLR three pin XLR ends, which are fully compatible with standard XLR connections. The XLR ends are a black anodized cast zinc shell with gold contacts, and are hand soldered with good strain relief.

Cheap SPY software, hardware?

*Need some hardware and software reccomendations.
I want to set up a camera and microphone to record a noisy neighbor who has been deliberately slamming his door in my apartment building. Camera and microphone will be mounted somewhere just outside my door. If cables are required, they'd have to be thin enough to fit between a door and a doorframe, very snug space.
The neighbor is maybe 12 feet away from my door, the hall is reasonably well-lit. Ideal situation would be to record it all with a time and date stamp, on my computer.
However, I'd like to do it all (mike, camera, software) for no more than $100. Links?

What is the difference between audio cables and instrument cables?

I'm looking at cables for my synth, and I notice that musiciansfriend.com has instrument as well as audio cables. What's the difference?

insturment cables have better shielding less chance of picking up stay signals
