The RFOFF is an RF modulator replacement that improves the composite and S-Video output from the Commodore 16 and Plus/4, and adds a few quality of life features. Not only are jailbars, checkerboarding and noise significantly reduced or eliminated, edges are enhanced without unwanted ringing.

The RFOFF is manufactured by The Retro Channel (TRC), and sold via [Lectronz], priced $35.00 (~€30.00) for the basic version with no luma bypass kit.

- Compatible with both PAL and NTSC
- Vastly improved S-Video and composite output
- S-Video jack replaces the old RF output
- Configurable 3.5mm output
- Chroma attenuated to 300mV as per the S-Video spec
- Adjustable luma:sync ratio (contrast control)
- Improved signals also available on the A/V DIN connector
- Fully assembled and ready to install (plus/4 version requires installing pin headers - see below)
- Optional luma bypass mod that further reduces checkerboarding and jailbars with S-Video
