Mikrofon preamp, channel-strip.
Mikrofon preamp og dynamics i en inputkanal af en kvalitet, der i sin prisklasse ligger langt over konkurrenterne. Det er hvad Focusrite TrakMaster Pro tilbyder.
TrakMaster Pro er en mic preamp med 48v phantom, ydermere har den også et dedikeret instrument indgang (jack). Highpass filter samt Mid Soop EQ, en Focusrite-specialitet, der ved sænkning af en variabel mellemtonefrekvens er ideel til problematiske vokaler.
Indbygget opto-kompressor med valgfri kompression og makeup gain og med 2 attack-tider. Focusrite har her tilføjet en speciel "Squash"-indstilling, der er ideel til intense tromme- og percussionlyde.
Der er en latency-fri monitordel, hvor du direkte kan høre hvad du indspiller, uden den forsinkelse, der altid opstår i et computerbaseret system.
TrakMaster Pro har også et flot, rundt & blåt VU-meter, som valgfrit kan vise input, output eller kompression.
Som option til TrakMaster Pro kan leveres et digitale output card.
