Περιγραφή:
Ο επαγγελματικός διαμορφωτής A/V 5806 της σειρας Τ.ΟΧ διαθέτει 2 εισόδους A/V STEREO (modules A και B) απο τις οποίες αναπαράγει δύο ανεξάρτητα κανάλια εξόδου PAL. Οι είσοδοι A/V για κάθε κανάλι, διαμορφώνωνται ανάλογα με το TV standard σε IF των 38.9 Mhz. Το διαμορφωμένο IF σήμα μετατρέπεται σε κανάλι PAL της επιλογής σας μεταξύ 46 και 862 Mhz. Η όλη επεξεργασία γίνεται χωρίς καμμία απώλεια στην ποιότητα του σήματος, εξασφαλίζοντας άριστο αποτέλεσμα στην έξοδο RF. Η συσκευασία περιλαμβάνει καλώδιο 3RCA-Mini Jack
Τεχνικά Χαρακτηριστικά:
— 2x Είσοδοι AV Stereo, 2x έξοδοι PAL
— LAN/ETHERNET θύρα για τοπικό/απομακρυσμένο έλεγχο και προγραμματισμό.

Product description:
Ref. 5806 features two A/V STEREO inputs (modules A and B) which generate two independent output channels PAL. The A/V inputs for each module are modulated according to the TV standard in an IF of 38.9 Mhz. The modulated IF signal is converted to any channel or frequency between 46 and 862 Mhz PAL. VSB output, Audio and video parameters configurable to set the signal in any standard. 9 possible channel tables : CCIR N.Z. Ind, China Taiwan, Chile M/N, Italy, France, Russia (OIR), Ireland, South Africa, Poland and Australia. Test socket (-30 dB) , located in the upper part of the front panel.
Technical features:
— 2χ AV Stereo inputs, 2x PAL outputs
— LAN/ETHERNET port, for on site/remote programming & control
