Gold-Plated RCA Jack Panel Mount Socket – Zinc Alloy Single AV Coaxial Socket for Audio/Video Panel Mount

Gold-plated zinc alloy RCA (phono) panel mount sockets for installation in amplifier rear panels, preamp chassis, AV equipment enclosures, and custom audio builds. Each socket mounts through a standard 8–9mm panel hole and is secured by a nut from the rear. The gold-plated center contact and outer shell provide low contact resistance and long-term corrosion resistance. Available in multiple colors (red, white, yellow, black) for standard AV color-coding: red = right audio, white = left audio, yellow = composite video.

Key Specifications

• Type: RCA (phono) panel mount socket (jack)
• Body Material: Zinc alloy, nickel or chrome-plated
• Contact Material: Brass, gold-plated
• Panel Hole: 8–9mm diameter
• Mounting: Rear nut (panel thickness up to 6mm)
• Impedance: 75Ω (matched to standard AV signal impedance)
• Colors: Red, White, Yellow, Black (select above)
• Quantity: 10, 20, or 40 pieces (select above)

RCA Color Code Standard

• Red: Right audio channel (analog stereo)
• White (or Black): Left audio channel (analog stereo)
• Yellow: Composite video
• Blue/Green/Red (component video): Y (luminance), Pb (blue difference), Pr (red difference)
• Orange: S/PDIF digital audio (coaxial)
• Color coding is a convention, not a technical requirement — all RCA sockets are electrically identical regardless of color. Use color coding to prevent wiring errors during installation.

Frequently Asked Questions

How do I wire an RCA panel mount socket?

The socket has two solder terminals on the rear: the center terminal (signal/hot) and the outer shell terminal (ground/shield). Connect the signal wire to the center terminal and the shield/ground wire to the outer shell terminal. For panel-mount applications, the outer shell is often connected to the chassis ground through the mounting nut — verify whether chassis grounding is appropriate for your application (it can cause ground loops in some audio systems).

Should I ground the RCA socket body to the chassis?

This depends on the application. For single-ended (unbalanced) audio systems: grounding the socket body to the chassis is standard practice and provides shielding. However, if multiple pieces of equipment are connected and each has its chassis grounded to mains earth, ground loops can occur — causing a 50/60Hz hum. To prevent ground loops: ground the socket body at one end of the signal chain only, or use isolated RCA sockets (with plastic insulating washers between the socket body and the chassis).

What panel thickness can these sockets accommodate?

The rear nut accommodates panel thicknesses up to approximately 6mm. For thicker panels, use a countersunk mounting hole or a socket with a longer threaded body. For thin panels (1–2mm), use a lock washer under the nut to prevent the socket from rotating when plugs are inserted and removed.

Can I use these sockets for S/PDIF digital audio?

Yes. S/PDIF coaxial digital audio uses standard RCA connectors at 75Ω impedance. These sockets are suitable for S/PDIF connections. Use orange-colored sockets for S/PDIF to follow the standard color convention and prevent confusion with analog audio connections.

Typical Applications

• Amplifiers: Input and output RCA sockets on integrated amplifiers and power amplifiers
• Preamplifiers: Source input sockets on tube and solid-state preamps
• AV equipment: Composite video and analog audio input/output sockets
• DIY audio: Custom amplifier and DAC chassis builds
• Patch panels: AV signal distribution panels in studios and AV installations
