Features

Level of protection

  • Class-AB output stage for low distortion sound and great sonority.
  • Undisturbed operation at the highest level through individually decoupled sections.
  • Separate power supplies for standby power and digital and analogue modules.
  • The wideband filter clears external balanced disturbances from the power grid and unbalanced disturbances from housing and „ground wire“.

Input switching:

  • High quality, encapsulated signal relay and hard-gilded contacts for optimum signal transmission.
  • Almost wear-free relay for an exceptional long lifetime.

Input Level:

  • Particularly low distortion and low-noise due to BI-FET operational amplifiers for the widest frequency range and clear increased dynamics in music reproduction.
  • Low-noise operational amplifiers from Texas Instruments for a sensitive input stage.

Signal Forwarding:

  • Efficient signal transmission with minimized distortion.
  • Optimized module architecture for short signal paths.
  • High-quality polypropylene film capacitors made in Germany.
  • Extreme interference suppression and loss-free signal forwarding through SMD technology (an innovative technology for the production of assemblies).

Real double-mono-construction:

  • Separate power supply for each channel, individual signal processing and individual signal amplification for more strength, dynamics and performance reserves.
  • Two separately operated, stray power supplies, a transformer and a rectifier for a finely-resolving and stable sound.
  • balanced inputs (XLR) for optimal signal transmission. This professional type of connection allows signal transmission with a ground wire exclusively used for shielding and on which itself no signal flow takes place.

Pre-amplifier and full-amplifier:

  • Professional, precise and logarithmic working volume adjustment as in the studio with real 1 dB steps.
  • Exactly synchronized volume control of the audio channels.
