P-COVOX is a very simple device, 4channel, discrete component digital-to-analog converter (DAC) that fits under PIA chip. It isn’t as Hi-Fi as modern sound cards, but it`s perceptiom may be a lot better than a POKEY  - especially playing MODs or NEO files

 

Main features :

  • easy fitting - one wire in most cases
  • high quality PCB
  • transparent for Atari OS / Hardware / Ultimate / etc. 
  • Equal audio output level on both channels
  • Optional pull-up resistors on DATA LINES / not fitted by default/
  • ROHS, PB Free

 

 INSIDE BOX :

  • A fully tested and assembled P_COVOX

 

INSTALLATION STEP BY STEP:

Disclaimer: If you are not familiar with soldering or you do not have proper tools, please LET a pro technician do it for you or send me your ATARI BOARD for installation. Upgrade installation cost is 10€ only. Contact me to arrange installation. Otherwise, please remeber - wrong tools usage or low skills may damage atari and ultimate; any damage/harm to your hardware is NOT subject of any kind of warranty.

 

If Your PIA chip is NOT socketed:

  • desolder PIA CHIP
  • solder precise socket into its place (supplied)
  • insert P_COVOX
  • Insert back PIA chip to P_COVOX

 

If Your PIA chip is socketed:

  • remove PIA CHIP
  • insert P_COVOX
  • Insert back PIA CHIP to P_COVOX

 

Connections to be made with small wire:

 

  • CTRL - select one pin pin only  to set covox`s  address page:
    • if you solder CTRL signal to pin 9 of LS138 on Atari board, covox will be present at $D600
    • if you solder CTRL signal to pin 10 of LS138 on Atari board, covox will be present at $D600
    • if you solder CTRL signal to pin 7 of LS138 on Atari board, covox will be present at $D700

 

 

O2 signal problems:

  • on majority of  ATARIs middle and RIGHT  pins of JP1 connector shall be jumpered / connected. No further actions required
  • if Your sound is distorted, remove the jumper; then  connect RIGHT pin of JP1 to CPU pin 39

 

 

DISCLAIMER:

connecting covox audio with stereo out is not a good idea. Covox loudness may be reduced. Thus, LM358 amplifier replacement - U-MIXER is being made to mix 2 pokeys, 2 covox audio to stereo out, mono out and modulator audio
