Manley VARIMU

MANLEY VARIABLE MU® LIMITER COMPRESSOR

“Mu” er rør-snak for gain, og Variable Mu® er Manleys registrerede varemærke for denne limiter-kompressor. Det fungerer ved at bruge “remote-cut-off” eller re-biasing af røret, for at opnå komprimeringen. Vintage Fairchild 670 bruger også denne teknik og den er en af de ​​få all-tube kompressorer, der kan det. Det unikke 5670 dobbelttriode rør er centrum i en peak-reducerings- og komprimeringshandling, som konstant bliver korrigeret af side-chainens ensretterrør – dette får 5670 til at ændre forstærkning. Bare sådan!
COMPRESSOR-funktionen har Soft-Knee 1,5 til 1, mens Sharp Knee LIMIT funktionen starter fra 4 til 1 og bevæger sig til et mere dramatisk forhold fra 20 til 1, ved limitering over 12dB.
