Systemforstærkere MA-4.100

Varenummer: 6030-XXXXX

MA-4.100 er en kompakt 4-kanals digital effektforstærker til medieapplikationer og små lydsystemløsninger. DSP-forstærkeren med en 4 × 4-matrix er ideel til f.eks. konference- og kursuslokaler samt til installation i mediemøbler. Den kan nemt integreres i mediekontrollen via RS-485 og kan nemt konfigureres med Fohhn Audio Soft via et USB-C-stik.
