Jump to navigationJump to search
The RF jack of the C64 is an interface that allows the use of a TV for visual and audio output instead of a dedicated monitor. The signal combines the picture and sound information using a single cable.
On the left side of the RF jack you often see a H-L switch or a control dial:
- The H-L switch switches between the channels 3 and 4 (only NTSC version)
- The control dial is used for adjusting the frequency of the HF modulator.
Connector pin assignment[edit | edit source]
The RF jack is a cinch connector (RCA jack).
Pin assignment
| Pin | Signal | Description |
|---|---|---|

Hints:
The HF signal is used by the PAL version (Europe) in the UHF aera (470-862 MHz) on channel 36 (picture carrier on 591.25 MHz). For the NTSC version (USA) in VHF aera (174-230 MHz) on channel 3 or 4. The impedance is 75 Ohm.
