DESCRIPTION

SPA pojačala su prvenstveno dizajnirana za integraciju u sisteme za glasovno uzbunjivanje, ali zahvaljujući svojoj fleksibilnosti, mogu se koristiti i za javna obaveštenja ili komercijalne aplikacije. SPA pojačala su sertifikovana prema EN54-16 standardu.

SPA montaža u 2U visok 19” rek orman, 2-kanalna pojačala. Transformator izolovan za 100 V, 70 V i 8 Ohm nisko impedansne distribuirane sisteme zvučnika.

Dostupna su tri modela u SPA asortimanu:

• SPA-2060: 2 x 60 W
• SPA-2120: 2 x 120 W - u skladu sa EN54-16 standardom
• SPA-2240: 2 x 240 W - u skladu sa EN54-16 standardom

SPA može da se napaja iz mreže od 220 VAC ili 24 VDC koja može da podrži rezervni sistem baterije za upotrebu u slučaju kvara na mreži i sistema za hitnu evakuaciju.

SPA pojačala imaju zaštitu od kratkog spoja na masu, kratkog spoja, preopterećenja i temperaturnog pregrevanja, uključujući nadzor impedanse linije sa maksimalnom devijacijom od 5% koristeći DIVA8 ili IDA8 sisteme za nadzor linije zvučnika. Podržavaju kablove sa jednim naponom i redundantnu petlju (A/B).
