XLR Female to 6.35mm Cable - 1.8m

XLR-635-1.8M

XLR female to 6.35mm jack, for mixers and amplifiers. Length 1.8 metres.

Length: 1.8 m
Connectors: XLR / 6.35mm

In-depth technical details

3-pin XLR (AES14-1992): pin 1 = ground/shield, pin 2 = hot (+), pin 3 = cold (-) -- this is what balanced audio physically is: pin 3 carries an inverted copy of the signal, so noise picked up equally by both conductors cancels at the receiving end. A 6.35mm TRS plug (two insulating bands) carries either unbalanced stereo (tip=left, ring=right, sleeve=ground) or balanced mono line-level (tip=hot, ring=cold, sleeve=ground) -- same physical wiring, different real meaning depending on the device.

End A

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.

End B

6.35 mm jack

01 Tip Carries the left channel in stereo use, or the whole signal in mono.
02 Ring The right channel. Crackle when you wiggle the plug is this ring losing contact.
03 Sleeve The common ground — the voltage reference the signal is measured against.
04 Insulating bands The black bands keep the conductors apart. Without them the channels short to ground.
05 Strain-relief boot Stops the wires flexing where they leave the plug — the exact point most cables fail.
06 Outer jacket The outer sheath protecting the conductors inside from abrasion and moisture.

How it works

Hybrid audio cable (XLR to unbalanced)

The XLR end is wired balanced (two opposite-polarity conductors), but the far end is single-ended. Differential noise cancellation only exists up to where the signal reaches the unbalanced jack, so the cable as a whole is limited by its weaker end.

01 The balanced XLR end Balanced only up to the point it converts to the unbalanced connector on the other end.
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. The XLR end carries hot, cold and ground on 3 pins; the 6.35mm end carries the same three conductors on tip (hot), ring (cold) and sleeve (ground) — a balanced TRS jack, not a mono TS plug.

Principle: Common-mode rejection of interference
XLR end: 3-pin, hot/cold/ground
6.35mm end: TRS (tip/ring/sleeve), balanced — not mono TS
