The SAPT274 locking jack connector solves the frustration of cables coming loose during live performances, recording sessions, and mobile gigs. This heavy-duty 3-pole female connector secures 1/4" TRS and TS connections that would otherwise disconnect from vibration or accidental cable pulls.

Built with nickel-plated contacts and solder terminals, this connector provides reliable signal transfer for balanced and unbalanced audio connections. The locking mechanism engages automatically when a compatible male connector is inserted, preventing accidental disconnects that can kill your sound mid-performance.

The 3-conductor design handles stereo signals, balanced mono signals, or insert connections commonly used in mixing consoles and audio interfaces. Heavy-duty cable retention and a durable boot protect the connection point from repeated plugging cycles and road wear.

Use these connectors for securing monitor feeds to stage wedges, connecting guitars to pedalboards, or any scenario where a dropped connection means dead sound. They're particularly valuable for outdoor events where wind and movement can work cables loose, or in high-energy venues where dancers and crowds create vibration issues.

Each connector features solder terminals for custom cable building and comes ready to wire with your choice of cable gauge. The nickel finish resists corrosion and provides long-term reliability in both studio and live environments.

Seismic Audio backs this connector with a one-year warranty and ships within one business day, keeping your audio connections secure and your signal path uninterrupted.

Technical Specifications

Frequently Asked Questions

What makes this a "locking" connector and how does it work?

The locking mechanism automatically engages when you insert a compatible 1/4" male connector, preventing the connection from coming loose due to vibration, cable movement, or accidental pulls. The male connector locks into place and requires intentional release to disconnect, making it ideal for stage applications where cables get stepped on or moved around.

Can I use this connector for both balanced and unbalanced signals?

Yes, this 3-pole connector handles both balanced TRS signals and unbalanced TS connections. The three conductors support tip, ring, and sleeve configurations, making it suitable for stereo signals, balanced mono audio, or insert connections commonly found on mixing consoles and audio interfaces.

What type of cable can I attach to this connector?

This connector uses solder terminals, so you can attach virtually any gauge of audio cable by soldering the conductors to the appropriate terminals. The heavy-duty cable retention system grips the cable jacket securely, providing strain relief for the solder connections during repeated use.

Do I need special male connectors to use with this locking jack?

You'll need male 1/4" connectors that are specifically designed to work with locking jacks - standard 1/4" plugs won't engage the locking mechanism. Look for male connectors labeled as "locking" or compatible with Neutrik-style locking systems to ensure proper engagement.

Is this connector suitable for high-output applications like guitar amps?

Yes, the nickel-plated contacts and heavy-duty construction handle instrument-level signals without issues. The secure locking connection actually makes this ideal for guitar rigs where cables can get pulled or stepped on, preventing signal loss during performance when you need it most.
