RCA Male & Female to Terminal Block Adapter – Solderless AV Audio/Video Connector for Speaker, Home Theater & CCTV

Solderless RCA-to-terminal block adapters combining an RCA plug or jack with a screw clamp terminal block — allowing bare wire to be connected to RCA equipment without soldering. The screw clamp terminal accepts stripped wire directly; tighten the screw to secure. Available in male (RCA plug, for connecting to RCA input jacks) and female (RCA jack, for connecting to RCA cable plugs) configurations. Used for connecting speaker wire, bare wire runs, and non-terminated cables to RCA-equipped amplifiers, AV receivers, CCTV recorders, and home theater equipment.

Male vs Female RCA Terminal Block Adapters

• RCA male plug + terminal block: The RCA plug inserts into an RCA input jack on the equipment. Use when connecting bare wire to an RCA input (e.g., connecting a bare wire audio source to an amplifier’s RCA input).
• RCA female jack + terminal block: The RCA jack accepts an RCA cable plug. Use when creating a panel-mount or in-line connection point where an RCA cable will plug in (e.g., creating a wall plate connection for a home theater system).

Frequently Asked Questions

Can I use these adapters for speaker wire connections?

Yes, for connecting speaker wire to RCA-equipped amplifiers and subwoofers. Note that RCA connections carry line-level signals (typically 1–2V), not speaker-level signals. Do not connect speaker-level output (from an amplifier’s speaker terminals) directly to an RCA input — the high voltage (10–100V) will damage the RCA input. Use these adapters for: (1) connecting a line-level source to an RCA input; (2) connecting a subwoofer’s RCA input to a line-level output; (3) CCTV composite video connections.

What wire gauge do the screw clamp terminals accept?

The screw clamp terminals accept 20–14AWG (0.5–2.5mm²) wire. For stranded wire, twist the strands tightly before insertion to prevent individual strands from escaping the clamp area. For the best connection, use wire ferrules (end sleeves) on stranded wire ends before inserting into the screw clamp.

Are these suitable for CCTV composite video connections?

Yes. CCTV analog cameras use composite video signals over RG59 coaxial cable with RCA connectors. These adapters allow bare RG59 cable (without pre-terminated RCA plugs) to be connected to DVR/NVR RCA video inputs. Connect the center conductor to the signal terminal and the braid/shield to the ground terminal of the screw clamp.

Typical Applications

• Home theater: Connecting bare wire audio sources to RCA-equipped AV receivers
• Subwoofer: Connecting line-level output to subwoofer RCA input
• CCTV: Connecting bare RG59 coaxial cable to DVR/NVR RCA video inputs
• DJ equipment: Connecting bare wire sources to RCA mixer inputs
• DIY audio: Creating custom RCA connection points without soldering
