4‑pole Speaker Cable Connector Omnitronic 30203515, 4 contacts for audio speaker connections

Omnitronic 30203515 is a 4‑pole speaker cable connector engineered for audio speaker connections that require four separate contacts. It provides a compact interface for transmitting left/right and additional channel or bi‑amp signals between an amplifier/processor and multi‑wire speaker cables. The connector is intended for installations in professional sound systems, home theaters, and custom audio setups where reliable contact and clear channel separation are needed.

Advantages

The 4‑pole design allows four individual conductors to be connected in a single housing, reducing cable clutter and simplifying terminations. Its compact form factor supports space‑constrained installations while maintaining secure mechanical and electrical connections. The connector is suitable for repeated insertions and removals and offers a straightforward wiring layout that helps reduce installation time and wiring errors.

Suitable for

• Bi‑amping speaker systems
• Multi‑driver loudspeakers with separate channels
• Custom home theater wiring
• Small professional PA or studio setups

Key specifications

• Number of contacts: 4
• Contact arrangement: four individual poles for separate conductors
• Application: speaker/audio signal connections
• Mounting style: inline cable connector for termination of multi‑wire speaker cable
• Construction: compact housing designed for repeated mating cycles

How to use

Strip the outer insulation of the speaker cable to expose the four conductors to the length recommended by the connector manufacturer, insert each conductor into its respective contact position, and secure the conductors according to the connector’s termination method. Ensure correct channel mapping (e.g., left/right, high/low) between the amplifier/processor and the speaker to maintain phase and channel integrity. After wiring, verify that all contacts are seated firmly and perform a continuity or speaker‑level signal test before final installation.

Usage recommendations

Use the connector in dry, protected environments and avoid excessive bending or strain on the terminated cable. Follow standard audio wiring practices to maintain polarity and prevent short circuits; label cables where multiple channels are present to simplify troubleshooting and future modifications.
