Kramer- TR-91 1 Audio Channel Transformer - Converts 4/8 to 70/100V - Max Power 10 - TR-91

Kramer TR-91 1 Audio Channel Transformer is an audio transformer designed to convert audio signals between different voltage levels, specifically converting 4/8-ohm speaker impedance to 70V/100V line levels, which are commonly used in commercial audio systems. This device is used for distributed audio systems, where speakers are connected over long distances and need to be driven with a constant voltage.

Key Features:

• Impedance Matching:

  • The TR-91 provides impedance matching by converting a 4Ω or 8Ω load to a 70V or 100V line. This allows you to integrate low-impedance speakers (commonly used in consumer-grade audio systems) into 70V/100V systems, which are standard in commercial audio installations.

• Max Power Handling:

  • The transformer can handle a maximum power of 10 watts, which is suitable for smaller to mid-sized audio installations. This allows it to be used in various applications where the power demand is moderate, such as conference rooms, retail stores, or smaller auditoriums.

• Versatile Use in Commercial Installations:

  • The TR-91 is designed to support 70V/100V distributed audio systems, which are ideal for long-distance audio transmission. This transformer ensures that audio can be transmitted over longer distances with minimal signal loss, allowing for multiple speakers to be connected across a large area without the need for multiple amplifiers.

• Simple Integration:

  • It’s a plug-and-play device, making it easy to integrate into existing AV or sound systems. The TR-91 requires no complex configuration or software setup, simply connect the speaker and amplifier and it will handle the voltage conversion.

• Compact Design:

  • The TR-91 is compact and easily integrates into rack-mounted AV setups or individual audio equipment spaces without taking up too much space.

• Cost-Effective Solution for Power Distribution:

  • This transformer offers a cost-effective way to expand and distribute audio systems without needing more expensive or complex audio equipment. It makes it simple for businesses and institutions to convert and distribute audio signals effectively.
