4-kanalno DSP instalacijsko pojačalo 4 x 120 W @ 4 Ohm / 70V/100V
Profesionalno 4-kanalno instalacijsko pojačalo
Snažno pojačalo klase D s 4 x 120 W na 4 Ohm (transformatorski bypass) ili 70V/100V izlazima kroz toroidni transformator
Prekidač za odabir stereo/paralelnog/mosnog načina rada po paru kanala
4 balansirana linijska ulaza i 4 izlaza za zvučnike s priključcima za terminale
Prednja ploča jednostavna za korištenje s LED diodama za signal, ograničenje, zaštitu, isključivanje zvuka i premosni način rada po kanalu i LED diodama za clipping za ulaze
Krugovi zaštite zvučnika: DSP limiter, prekomjerna struja, istosmjerna struja, pregrijavanje, kratki spoj, kao i preklopni automatski način rada u stanju pripravnosti
DSP unaprijed postavljene postavke s HPF i LPF koji se mogu aktivirati putem DIP prekidača
DALJINSKA audio i upravljačka sabirnica temeljena na CAN arhitekturi (Controller Area Network)
Opremljeno za buduće LD Systems daljinske upravljačke ploče i mikrofone za pozivanje
Utor za buduće opcionalne kartice za proširenje za Ethernet ili Ethernet + Dante
