3.5mm stereo socket to two RCA plugs, a compact adapter (not a cable) for amplifiers and mixers.

Type: Adapter
Connectors: 3.5mm / RCA

In-depth technical details

The 3.5mm (TRS) end of this cable is wired tip=left, ring=right, sleeve=ground, and splits into two RCA plugs using the standard stereo-audio color code -- white = left channel, red = right channel.

End A

3.5 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.

End B

RCA / phono

01 Centre pin Carries the signal itself — one channel of audio, or a whole composite video picture.
02 Outer collar Ground and shield in one. It mates before the centre pin, which is what stops the loud pop.
03 Colour code Red is right, white is left, yellow is composite video. A convention only — electrically the plugs are identical.
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.

From the published standard

How it works

In an unbalanced connection one conductor carries the signal while the braid serves as both ground and shield. There is no inverted copy to cancel noise, so hum and hiss start to appear after a few metres, particularly near mains cable or power supplies. For long runs the answer is a balanced connection, not a longer unbalanced cable.

Principle: Single-ended — no noise cancellation
Practical length: Short runs; hum risk grows with distance and nearby mains
Colour convention: Red = right, white = left, yellow = composite video
