1140-MS-A

Overview

The Hammond Manufacturing 1140-MS-A is a microphone splitter audio transformer designed for chassis mounting. It features an impedance ratio of 150 to 150 ohms, facilitating signal distribution in professional audio environments. The component utilizes wire lead termination for circuit integration and operates within standard industrial temperature ranges. Constructed for durability, it supports single primary and secondary winding configurations typical of isolation transformers. This unit serves as a specialized passive component for maintaining signal integrity while splitting audio feeds.

Feature Summary

• Provides balanced signal splitting for microphone inputs
• Ensures electrical isolation between source and destination circuits
• Maintains consistent impedance matching across split channels

Applications

• Professional live sound reinforcement systems
• Broadcast studio microphone distribution networks
• Recording studio signal routing setups

Procurement Notes

Verify the specific manufacturing date code against project requirements to ensure compliance with current RoHS directives. Confirm that the wire lead gauge meets the mechanical strain relief needs of the intended chassis installation. Cross-reference the datasheet revision history to validate pinout compatibility with existing PCB layouts or wiring harnesses before finalizing procurement orders.

Selection Notes

Select this model when a dedicated 1:1 impedance matching splitter is required for low-level microphone signals. It is suitable for applications demanding high isolation without active electronics. Consider the chassis mount form factor for fixed installations where space constraints preclude larger rack-mounted solutions. Ensure the operating environment does not exceed the thermal limits specified for continuous duty cycles.

Part Context

This component belongs to Hammond Manufacturing's line of audio transformers, specifically engineered for the audio processing sector. It complements their broader portfolio of power and signal transformers by addressing niche requirements in audio signal distribution. The 1140 series represents a standardized solution for engineers requiring reliable passive splitting capabilities in analog audio chains.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with alternative models from other manufacturers based on impedance ratio and physical dimensions if sourcing changes occur.
