Parallel port soundcard with high quality tuning options, compatible with Covox Speech Thing
Line out connection, intended to connect to amplified speakers
Optional Dual Color (Black + Red) high quality enclosure.
No compromises, we wanted to make the best possible covox clone, and did not spare effort or expenses :
after building 3 prototype generations (CVX1, CVX2, CVX3), this is now the final version : CVX4 uses very high precision 0.1% all same value resistors, and a reverse engineered schematic (based on a real original covox) for excellent 8 bit sound. Other DIY clones use 1% or 5% resistors, different schematic, ...you can compare... CVX4 sounds way better...
Added low pass tuning options to simulate speaker effect to your own taste.
Enclosure assembly tip : The top and bottom are printed to tight tolerances, for a good fit. When assembling, don't use excessive force.
Assembly is easy, following these steps :
- put the top lid in front of you, so that you can read the 'CVX4' text
- tilt the lid, and fit the right side notch first.
- after this first, you can gently move the lid downwards, while pulling it to the right, and fit the other notches.
