ART Tube MP/C mikrofon rør forforstærker med compressor
Tube
MP/C (PreAmplifier/Compressor) er et multi-purpose værktøj til
lyd-recording. To uafhængige kredsløb tilbyder en rørbaseret analog
forforstærker og en VCA-less kompressor med optisk
gain-reduktionskontrol. Tube MP/C er designet til at virke med ethvert
optagelses, lydforstærkene eller elektrisk instrument-setup.
Forforstærkerens aktive, balancerede input tilbyder ekstremt lav støj
og sublim common-mode-rejection. Tube MP/C's anden fase kører på
reguleret DC volt som tilbyder ekstra 20 dB gain.
