Accoustic Art Preamp II MK II
TUBE PREAMP V highlights

Audiophile reference preamplifier with a “tube hybrid” concept and 4 reference tubes (2 tubes per channel)
Fully balanced circuit design from input to output
Further optimized sound quality by new designed main board
Advantages of this “tube hybrid” technology:
– very high bandwidth
– very low distortion factors and a “good-natured” distortion spectrum
– “analogue” 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”
Fully balanced circuit design from input to output
High end Class A output stage
New with colour high resolution display
All components used are of outstanding quality (e.g. Burr Brown® OPA 627) and additionally selected; all relays have high quality gold-plated contacts
New 4-channel digital volume control for best crosstalk
All relays have high quality gold-plated contacts
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)
2 x unregulated, switchable output for the connection of an external headphone amplifier (1 x RCA/ Chinch), 1 x (XLR) Phase switch for 0° and 180°
2 magnetically shielded, encapsulated 50 VA toroidal core transformers („Made in Germany“) of premium quality for high output reserves
Front panel and covers are made of massive and solid aluminium; turning knobs are made of massive and chromed brass
Standard Remote Control included – RCII (volume control only).**
ACCUSTIC ARTS® TUBE PREAMP V is “Handmade in Germany”
