4 in 4 out Composite Video Amplifier, RCA Connector
The 4 in 4 out composite video amplifier is designed to boost and distribute analogue video signals over long distances while maintaining image quality. With RCA connectors, 1000 m transmission range and image controls, it’s ideal for CCTV and AV installations that need reliable multi-channel video.
Use it to stabilise video feeds from cameras, DVRs, multiplexers, VCRs and other AV sources wherever cable length, splitting or interference would otherwise degrade picture quality.

This amplifier improves and stabilises low-level or long-distance composite video signals so your monitors and recording devices receive a strong, clean picture.
- Amplifies video gain to compensate for signal loss over coaxial cables.
- Provides HF (high-frequency) compensation to recover fine image details.
- Lets you tune image quality via front-panel sharpness and brightness adjustments.
- Supports multiple devices thanks to four input and four output channels.
Where can you use the 4 in 4 out video amplifier?
The unit is purpose-built for security and AV environments where consistent video quality is essential, even when equipment is spread across a site.
Typical applications
- CCTV systems: Boost camera feeds running over long RG59 coax to DVRs or monitors.
- Security control rooms: Stabilise multiple analogue video feeds going into multiplexers.
- AV and broadcast accessories: Improve composite output from VCRs, DVRs or media players.
- Large venues: Extend video to distant displays in halls, campuses or retail spaces.
Because it uses standard RCA connectors, integration with existing analogue equipment is fast and straightforward.
