Overview

The Kramer Electronics 810 is a dedicated composite video and audio tone generator built for AV professionals who need a quick, reliable way to test and troubleshoot signal chains. It simultaneously produces two composite video color bar signals, one S-Video (Y/C) output, and a 1kHz audio reference tone, allowing technicians to verify multiple signal paths from a single source without juggling separate generators. A front-panel switch lets you select between PAL and NTSC standards, making the unit suitable for use in any region or mixed-standard facility.

Built in the compact Kramer TOOLS housing, the 810 occupies minimal bench space and can be rack-mounted alongside two other TOOLS-series devices in a single 1U rack space using the optional RK-3T adapter. This makes it well-suited for permanent installation in equipment racks, mobile production carts, or integration test stations. While it focuses exclusively on analog composite and S-Video outputs, the 810 remains a practical and cost-effective tool for maintaining and calibrating legacy AV infrastructure where these signal formats are still in active use.
