AT-661w

Varenummer: 1023-XXXXX

AT-661w er et passivt, hornbelastet fullrange-højttalersystem. Den er specielt udviklet til udendørs brug og har et vejrbestandigt hus, vandtætte forbindelser og membranimprægnering. Den imponerer med sin høje ydeevne og fremragende taleforståelighed.

Main features

  • 2 × 10" / 1,4" kompressionsdrivere (3,5" membran) på det drejelige CD-horn
  • Elektronisk højfrekvensbeskyttelse
  • Nominel effekt: 600 watt ved 4 ohm
  • Spredning: 90 ° × 60 ° (H × V)
  • SPL max.: 138 dB
  • Tilslutninger: 2 × 4-pin terminal med vandtæt kabelforskruning
  • Vejrbestandigt VSM-hus forstærket med stålforstærkninger
  • Resistent PU-belægning er standard
  • Kan fås i RAL Classic, NCS eller Pantone-farver på forspørgsel
  • Vejrbestandige monteringsmuligheder (af rustfrit stål) er tilgængelige på forespørgsel
  • For at sikre ydeevne og driftssikkerhed er Fohhn-systemforstærkere med den korrekte højttalerforindstilling påkrævet.
