Video Transformer Delta TRO-1/400 — audio/video signal transmission transformer

Delta TRO-1/400 is a video transformer engineered for audio/video (AV) signal transmission and galvanic isolation. It offers impedance matching between video sources and receivers and helps mitigate ground loop interference when connecting equipment over coaxial or twisted-pair cabling. The device is suitable for CCTV systems, video distribution setups and professional AV installations that require signal integrity and electrical isolation.

Advantages

The transformer provides galvanic isolation to prevent direct current paths between connected devices, reducing hum and interference caused by ground loops. Its impedance matching capability supports stable signal levels and minimizes reflections on transmission lines. The compact design facilitates integration into rack-mounted equipment or inline signal paths without occupying significant space. Constructed to meet professional AV needs, it maintains consistent performance across standard video bandwidths.

Suitable for

• CCTV camera signal isolation and distribution
• Video distribution in multi-room or multi-monitor setups
• Professional AV systems requiring galvanic isolation
• Long-distance analogue video transmission where ground loops or impedance mismatch are concerns

Key specifications

• Function: audio/video signal transformer providing galvanic isolation and impedance matching
• Application: analogue video (CCTV, composite video distribution) and AV signal lines
• Mounting: compact inline/component form suitable for integration into AV racks or equipment boxes
• Signal compatibility: supports standard analogue video bandwidths and levels used in CCTV and composite video systems
• Primary benefit: reduction of ground loop interference and improved transmission stability over cable runs

How to use

Install the transformer inline between the video source output and the receiver input, ensuring correct orientation where indicated by the device markings. Use matching cable types and maintain proper connector terminations to preserve impedance continuity. For CCTV applications, place the transformer at the camera end or at the receiver end as required to break ground loops; for distribution systems, integrate the unit at each branch point needing isolation. Verify signal levels and image quality after installation and adjust any downstream termination or equalization as necessary.

Usage recommendations

Confirm compatibility with the specific analogue video format in use and follow standard AV grounding practices. When resolving hum or interference, test isolation placement both at the source and at the receiving equipment to determine the most effective location. Avoid exposing the transformer to excessive mechanical stress, moisture, or extreme temperatures to maintain reliable operation.
