Overview
The Visaton TR 84 is a chassis-mount audio transformer designed for public address systems. It facilitates the connection of low-impedance speakers to high-voltage distribution networks. The primary winding supports power ratings of 10 W at 1 kOhm, 6 W at 1.7 kOhm, and 3 W at 3.3 kOhm. The secondary output provides selectable impedances of 4 Ohms or 8 Ohms. The component operates within a frequency range of 20 Hz to 20 kHz with a -3 dB response tolerance. The net weight is 0.32 kg.
Feature Summary
- Enables integration of standard 4 Ohm or 8 Ohm speakers into 100 V constant voltage PA networks
- Provides multiple primary impedance taps to match varying amplifier outputs
- Chassis mounting design ensures secure installation in professional audio equipment
Applications
- Public address system speaker connections
- 100 V line distribution networks
- Professional audio installations requiring impedance matching
Procurement Notes
Verify the specific primary impedance tap required (1 kOhm, 1.7 kOhm, or 3.3 kOhm) against the source amplifier specifications before procurement. Confirm that the secondary load matches the connected speaker's impedance rating of either 4 Ohms or 8 Ohms. Ensure the chassis mount configuration fits the intended enclosure dimensions. Check local regulatory compliance markings such as WEEE registration numbers if applicable for the target market.
Selection Notes
Select this transformer when adapting low-impedance dynamic speakers for use in distributed 100 V audio systems. Choose based on the available primary impedance options from the amplifier output stage. Ensure the total power consumption across all connected transformers does not exceed the amplifier's rated capacity. Consider the physical size and mounting requirements for the installation environment.
Part Context
The TR 84 belongs to Visaton’s series of audio transformers used in signal and power distribution. It serves as an interface component between amplifiers and loudspeakers in fixed installations. The product is categorized under audio transformers and signal transformers, distinct from microcontrollers or general-purpose electronic components despite potential naming ambiguities in some listings.
Replacement Considerations
No direct substitute part numbers are publicly confirmed by the manufacturer. When replacing, ensure the new component matches the 100 V primary network requirement and offers compatible secondary impedance options of 4 Ohms or 8 Ohms. Verify that the power handling capabilities and frequency response meet the original system specifications.
