> Tube Preamp II - MK2
Audiophile reference preamplifier with a so called “tube hybrid” concept and 4 military tubes (2 tubes per channel)
Fully balanced circuit design from input to output
Advantages of this “tube hybrid” technology:
- very high impedance
- very high bandwidth
- very low distortion factors and a “good-natured” distortion spectrum
- “analog” and very precise sound performance
- 4 separated amplification paths, which are not influencing each other
Easy change of tubes without any adjustments just “plug and play”
Professional Class A output stage using technology derived from studio engineering
All used components are of outstanding quality (e.g. Burr Brown® OPA 627) and additionally selected; all relays have high quality gold plated contacts
- 4 high precision military tubes; 4-times selected
- 4-channel volume potentiometer for best crosstalk
- 3 x fully balanced high level inputs (XLR) and 2 x unbalanced high level inputs (RCA)
- 1 x unbalanced input (RCA) configured as “SURROUND-BYPASS”
- 2 x fully balanced outputs (XLR) – 1 x AC coupled, 1 x DC coupled
- 2 x unbalanced outputs (RCA) – 1 x AC coupled, 1 x DC coupled
- 1 x headphone output, switchable (1/4" stereo female jack)
- 1 x unregulated, switchable output for the connection of an external headphone amplifier (RCA)
- Phase switch for 0° and 180°
- 2 magnetically shielded, encapsulated 75 VA toroidal core transformer („Made in Germany“) of premium quality for high output reserves
- Front panel, cover and remote control are made of massive and solid aluminium; turning knobs made of massive and chromed brass
- ACCUSTIC ARTS® AMP III is “Handmade in Germany”
