== Description ==
In the miniature layout seen below a bypass diode (1N4001) was also added to the supply input. This diode protects the IC in case the user wrongly connects the power the circuit, which would otherwise result in the AD724 being fried. This diode isn't currently shown in the schematics, nor is it included in the large S-Video plus composite layout below. (Schematics and large layout , but will be modified added soon).
* If your modulator only has the S-Video ouput, you can still connect to a composite TV input by using an S-Video to composite adapter. This adapter combines the Chrominance and Luminance signals back together (passively), but again the quality will not be as good as the S-Video picture, so this method should only be considered as a last resort.
== Internal Installation ==
If you do decide to install the miniature version of the modulator inside a CPC or even just give it a casing, the following dimensions can be used. The 42mm x 27mm dimensions of the PCB may vary slightly.

The new mini version is a mere 32mm x 25mm and is even easier to fit inside most computers.
