en fait sur la péritel tu as à la foi les signaux vidéo et audio
le problème si ca marche pas, c peut-être que le cable qu´il t´as filé sert à envoyer le son de l´ampli vers la tv au lieu du contraire, car il y a des entrées et sorties vidéo et son sur la péritel.
si c branché sur les entrées son au lieu des sorties, ca ne marche forcément pas...
mais le seul moyen de vérifier c de démonter ta peritel et de vérifier :
The VCR to Hi-Fi / Television to Hi-Fi Connecting Cable
Only three pins are needed take stereo audio from a video cassette recorder or television to a Hi-Fi unit using the Peritel SCART connector . ..
* Pin 1 - Right Audio Out
* Pin 3 - Left Audio Out / Mono Audio Out
The connection should be made using either one, two-core shielded cable or two, single core shielded cables. The decision on which to use will normally depend on the input connection required to the Hi-Fi unit; 3 or 5-pin DIN ( one, two core cable ) or phono jacks ( two, one-core cables ) .
The left audio line should be connected to pin 3 and the right audio line should be connected to pin 1. The shield of each cable should be connected to pin 4.
If the video recorder or television provides a monophonic output only; then a connection need only be made to pin 3 although the output may also be present on pin 1 on some equipment.
Because audio signals are sensitive to distortion and interference it is necessary to use suitable cable for all connections to avoid cross-talk and other problems.
If there is interference on the sound channels, such as mains hum; it may be necessary to leave the shields unconnected at the Hi-Fi inputs or leave the shield connections to pin 4 at the Peritel SCART connector off ( separating the two cable shields at that point ) . Some experimentation may be necessary to remove any interference.
