Overview
The Hammond Manufacturing 834A is a broadcast audio transformer designed for interstage coupling applications. It operates within a frequency range of 50 Hz to 15 kHz and features a 1:4 impedance ratio. The unit provides primary impedances of 10 kOhms or 40 kOhms and secondary impedances of 125 Ohms or 500 Ohms. Physical dimensions are 44.5 mm in length, 31.8 mm in width, and 65 mm in height. The component weighs approximately 226.796 g and utilizes chassis mounting.
Feature Summary
- Provides isolated signal coupling for broadcast audio circuits
- Features shielded construction to minimize electromagnetic interference
- Supports multiple impedance matching configurations for flexible integration
Applications
- Broadcast audio system interstage coupling
- Professional audio equipment signal processing
- Audio transformer circuits requiring specific impedance ratios
Procurement Notes
Verify the specific impedance configuration required for your circuit design, as the 834A offers selectable primary and secondary impedance options. Confirm that the physical chassis mount dimensions align with your enclosure space constraints. Ensure compatibility with the operating frequency range of 50 Hz to 15 kHz for your intended audio application before finalizing procurement.
Selection Notes
Select this model when a 1:4 impedance transformation ratio is necessary for audio signal transmission. Consider the physical size and weight if space is limited in the assembly. Verify that the available impedance combinations meet the source and load requirements of your specific audio stage. This component is suitable for environments where shielded audio transformers are mandated.
Part Context
The 834A belongs to the Hammond Manufacturing 800 series of audio and signal transformers. This series is engineered for professional audio and broadcast applications requiring reliable signal isolation and impedance matching. The product line emphasizes durability and consistent performance in demanding electrical environments.
Replacement Considerations
The 835A serves as a related variant within the same series but differs in its specific impedance characteristics and application focus. Evaluate the 842A for alternative impedance configurations if the 834A specifications do not fully match the circuit requirements.
