540A/640A V2.0 Integreret forstærker

6Direct

Denne knap giver lydsignalet en mere direkte vej til forstærkerens forstærkningstrin ved at omgå tonestyringskredsløbene og dermed få den renest mulige lydkvalitet.

7Bas og diskant

Med disse knapper kan du finjustere lydens tonemæssige balance. Når disse knapper står i midterste position, har de ingen effekt. Knapperne regulerer kun lyden igennem højtalerne og Pre-Out-stikkene - de påvirker ikke de signaler, der sendes igennem Tape Out-forbindelserne. Med en cd af høj kvalitet og et godt system er disse knapper unødvendige og kan derfor slukkes helt med Direct-knappen. Hvis optagelsen er af ringe kvalitet, eller andre faktorer påvirker lydkvaliteten, kan det være nødvendigt at justere bas og diskant for at kompensere.

8Lydstyrke

Bruges til at hæve/sænke lydniveauet fra forstærkerens udgange. Denne knap påvirker højtalernes, forforstærkerens og hovedtelefonernes lydniveau. Den påvirker ikke Tape Out- forbindelserne. Det anbefales, at lydstyrkeknappen drejes helt om mod uret, inden der tændes for forstærkeren.

9Balance

Med denne knap kan du justere de relative effektniveauer for venstre og højre kanal. I den midterste position er effekten fra hver kanal ens. Denne knap regulerer kun lyden igennem højtalerne og Pre-Out-stikkene - den påvirker ikke de signaler, der sendes igennem Tape Out- forbindelserne.

10Aux, CD, Tuner/DAB, DVD, AV/MD

Tryk på den relevante knap til valg af indgang for at vælge den kildekomponent, du ønsker at lytte til. Det valgte signal sendes også til Tape Out-stikkene og kan derfor optages. Indgangen bør ikke ændres under afspilning, men det optagede signal kan dog kontrolleres med indgangen Tape Mon.

11Tape Monitor

Ved at bruge denne knap kan du lytte til signalet fra en båndoptager eller signalprocessor, der er tilsluttet forstærkerens Tape In-/Rec Out- stik. Når Tape Monitor er valgt, sendes den valgte kildekomponent fortsat til Rec Out-stikkene til optagelse eller bearbejdning.
