Stereo 2/3 Vejs, Mono 4-Vejs Delefilter
Oplev professionel lydkvalitet med dbx 234s, en alsidig crossover designet til at optimere dit PA-system. Ved hjælp af præcisionsfiltre adskilles lydsignaler, og de korrekte frekvenser sendes til dine højttalerdrivere. Dette reducerer forvrængning, maksimerer forstærkerens ydeevne og leverer en klar og fyldig lydoplevelse.
Funktioner
- Valgbar stereo 2/3-vejs eller mono 4-vejs operation.
- TRS balancerede ind- og udgange.
- 40 Hz low-cut filter for begge kanaler.
- 24 dB per oktav Linkwitz-Riley filtre for præcis frekvensdeling.
- Uafhængige niveaukontroller og fasevender på alle udgange.
- Indikatorer for stereo/mono-status.
Fordele
Denne crossover er ideel til både professionelle lydinstallationer og transportable systemer. Med sin robuste konstruktion og intuitive betjening er dbx 234s et pålideligt valg til at opnå førsteklasses lyd.
