XLR to XLR Microphone Cable - 20m

AUD-XLR-XLR-20M

A microphone lead. The XLR end is balanced, so noise picked up along the run cancels at the far end.

Length: 20 m
Connectors: XLR

In-depth technical details

XLR's 3 pins carry a real signal, not just a shape: pin 1 = ground/shield, pin 2 = hot (+), pin 3 = cold (-). This is physically what balanced audio is -- pin 3 carries an inverted copy of the signal, so noise picked up equally by both conductors cancels out at the receiving end.

Connector anatomy

XLR

01 3 pins: ground, hot, cold The signal is sent twice, one copy inverted. The far end flips it back and adds them, cancelling any noise the cable picked up.
02 Locking latch You must press the latch to release it, which is why a stage microphone does not come unplugged when someone trips on the cable.
03 Metal barrel The barrel is grounded and acts as a shield around all three pins.
04 Strain-relief boot Stops the wires flexing where they leave the plug — the exact point most cables fail.
05 Outer jacket The outer sheath protecting the conductors inside from abrasion and moisture.

How it works

Balanced audio cable

Two wires carry the same signal in opposite polarity. Any noise the cable picks up hits both equally, so the far end cancels it by subtraction. That is why a balanced cable runs tens of metres without hum.

01 Two conductors, hot and cold The signal and its inverted copy, the basis of noise cancellation.
02 Shield A grounded conductive wrap that absorbs electromagnetic interference before it reaches the signal.
03 Outer jacket Protects everything inside mechanically. It plays no electrical role.

From the published standard

How it works

A balanced cable sends the signal twice on two wires, one of them polarity-inverted. Any noise the cable picks up along its length hits both wires equally, so when the far end flips the inverted copy back and adds them, the signal doubles and the noise cancels. This is common-mode rejection, and it is why microphone cables work over tens of metres without hum.

Principle: Common-mode rejection of interference
Conductors: Hot, cold and ground, inside a shield
Connector: XLR, 3-pin, latching
