Calrad 30-489tb-5pk 3.5mm Stereo to Screw Terminal 5pk

Product Description

The CALRAD 30-489tb-5pk is a 5-pack of audio adapters that convert a standard 3.5mm stereo male plug to a screw terminal interface. Each adapter bridges the gap between a 3.5mm stereo source and bare-wire termination points, making it well suited for custom audio installations where a permanent or semi-permanent connection is required. Installers working on distributed audio, intercom systems, or custom speaker wiring use these adapters to avoid soldering while maintaining a secure, low-resistance connection at the terminal block.

This adapter set is used in residential and light commercial audio wiring applications. Typical scenarios include connecting a media source with a 3.5mm output to in-wall speaker wiring, custom AV panels, or multi-zone audio systems where screw terminal blocks are the standard termination method. The 5-pack format reduces per-unit cost and provides spares for ongoing service work or staged installations.

Key Features

• Converts 3.5mm stereo male plug to screw terminal output for tool-free wire attachment
• Screw terminal interface eliminates the need for soldering at the connection point
• 5-pack quantity supports multi-room or multi-zone installations and provides backup units
• Compact form factor fits in tight enclosures and wall plates

Compatibility

Designed as a standard adapter for any audio source or device equipped with a 3.5mm stereo output, connecting to screw terminal inputs common in distributed audio and custom AV wiring systems.

Installation Notes

Installation is typically performed by AV integrators or low-voltage technicians. Power down or mute the audio source before connecting or disconnecting the adapter to prevent signal transients that could damage speakers or amplifiers. Use an appropriate small flathead screwdriver to seat conductors firmly under the screw terminals. Follow local low-voltage wiring codes as applicable to the installation environment.
