INTRODUCTION
Thank you for purchasing the Janus preamplifier. The Janus is a groundbreaking
audio component which combines sonic quality, innovative features and build quality
with lineage directly traceable to the reference Callisto line stage and Io phono stage.
Janus contains solid state circuitry but all of its amplification is achieved using vacuum
tubes. The output stage is a vacuum tube based differential driver. There is no global
feedback used in the Janus whatsoever.
Janus’ advanced microprocessor-based control circuitry is completely inactive when not
in use i.e. when not receiving a command from the user, resulting in no ill effects on
sound quality. The unit contains innovative features, such as a switched resistor volume
control, theater bypass mode, phase inversion and others.
The massive power supply consists of a high voltage transformer, heater transformer, and
high voltage choke. All of the magnetic components are shielded by a stainless steel
transformer cover, which also performs double duty as a structural truss. The high
voltage power supply is regulated with a discrete transistor-based regulator. The low
voltage solid state power supplies are discretely regulated.
Only the highest quality components are used in the Janus, including Roederstein
resistors, RelCap film capacitors, Mercury Magnetics transformers and Nichicon audio
grade electrolytic capacitors.
We hope you enjoy many years of music using the Janus preamplifier.
PLACEMENT
Janus should be located away from possible sources of hum such as power cords, power
transformers and the like.
Ventilation is critical for reliability. It should not be located on top of any heat source
such as a power amplifier. If it is positioned within an enclosed space then fans may be
warranted. All air vents must remain unobstructed. A minimum of 3 inches of space
above the unit is required.
