Janus

Mono Amplifier

Monoblock power amplifier with “infinite slew” current transfer circuit and “quiet overload” protections.
The power stage is based on a topology in which the input signal is translated into a current which is amplified and then fed to the load connected to the output. His amplification method allows for the overcome of the typical limitations of voltage amplifiers. Particularly, it is most effective on high power transient response, due to the absence of the sew effect.

The use of the current transfer circuit delivers amazing dynamics, an absolute tonal coherence at all listening levels and an easy match with every kind of speakers.
The Janus monoblock power amplifier is provided with both balanced and single-ended inputs, the latter with both non-inverting and inverting facility.

This allow for easy bridge connection of two monoblocks and absolute phase restoring when using an inverting preamplifier. This feature gives the user the possibility to always listen to the music with its original phase.
