Owi Incorporated 725TR 70 Volt 25 Watt Speaker Transformer

Product Description

The OWI INCORPORATED 725TR is a 70-volt line matching transformer rated at 25 watts maximum, designed for use in distributed audio speaker systems. It steps down the high-impedance 70-volt line signal to the appropriate impedance level for individual speaker loads. This type of transformer is a core component in commercial and multi-zone audio installations where multiple speakers are wired in parallel across a single amplifier output. Installation is typically performed by licensed electricians or low-voltage audio technicians familiar with 70-volt distributed sound systems.

The 725TR suits commercial, institutional, and large residential audio distribution applications. Typical installations include background music systems in retail spaces, restaurants, offices, houses of worship, and similar multi-speaker environments. In a 70-volt system, each speaker tap transformer like the 725TR allows independent volume tapping and impedance matching without significantly loading the amplifier, making it practical to run many speakers from one amplifier channel.

Key Features

• 70-volt line compatibility for distributed audio speaker systems
• 25-watt maximum power rating for appropriate load matching
• Designed for parallel multi-speaker wiring configurations
• Compact form factor suitable for in-cabinet or in-wall installation near speaker locations

Compatibility

Designed as an OEM-style replacement or add-on transformer for 70-volt distributed audio speaker systems requiring a maximum 25-watt tap transformer.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician in accordance with applicable NEC low-voltage wiring requirements. De-energize the amplifier and 70-volt line completely before making any wiring connections to the transformer. Ensure the combined wattage of all transformers on the line does not exceed the amplifier output rating. Do not exceed the 25-watt maximum tap rating of this transformer.
