Mackie HR824 Actieve Studio Monitor Speakers

De Mackie HR824 actieve studio monitor speakers zijn een begrip binnen de pro-audio wereld. In veel studio’s worden ze gebruikt om eindmixen af te luisteren. Ze klinken clean, strak en kunnen snoeihard spelen. Deze versie is nog uitgerust met analoge class AB versterkers wat resulteert in een tikkeltje warmer geluid. Veel producers prefereren daarom de MKI boven de latere MKII. Ben je op zoek naar strak, krachtig en evenwichtig klinkende speakers dan zijn de Mackie speakers wellicht iets voor jou. Ze zijn perfect af te stellen op je luister condities en zijn door ons volledig nagekeken tijdens een kleine beurt waarin de nodige onderdelen zijn vervangen. Ze worden daarom ook met 60 dagen garantie geleverd.

De speakers staan in Het Magazijn op Voorstraat 180 in Dordrecht. Maak een afspraak met Vintage Audio Repair om ze te beluisteren, dit kan ook in een stille luisterkamer. Mail of bel ons.
