Présentation

En simplifiant au maximum l'architecture interne Fred Forssell le créateur, nous offre un préampli disposant d'un gain maxi de 84 avec un rapport signal/bruit remarquable !! Un premier étage de puissance allant de +6 à +63 dB est accessible via un potentiomètre Grayhill et un autre gain de +21 dB (en sortie) donnent un gain total de 84 dB, le préampli dispose aussi d'un inverseur de phase, d'un filtre coupe bas et d'un voyant de surcharge.

Caractéristiques

(traduction en attente)

Electronics
Gain is >83 dB at 1 kHz, balanced in to balanced out
Positive polarity is pin 2 on XLRs, tip on ¼ " stereo jacks
Balanced outputs clip above +28 dBu, 100k load
Unbalanced XLR output load reduces max level by ~6 dB
Unbalanced ¼" TRS outputs clip at +22 dBu, 100k load
Frequency response: down 3 dB at 6 Hz and 300 kHz
THD at 1 kHz is .005% with 22 Hz to 22 kHz bandwidth
EIN, (weighted noise figure): -130 dBu, 150 Ω input
Balanced mic input impedance: >30,000 Ω
Microphone input electronics are DC coupled
Mic inputs are zener protected from external P48 DC
Mic inputs shut off while external DC is present
Green LED snaps on at ~ - 5 dBu
Yellow LED is variable brightness from ~ 0 to +20 dBu
Red LED snaps on at ~ +20 dBu
High-pass filter: 12 dB per octave and -3 dB at 100 Hz
Power supply provides two 17.25 VAC outputs
