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 sta\
ge. 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 th\
e Janus
whatsoever....](http://img.usermanuals.tech/thumb/217/3112/w300_janus-owners-manual-1478606521_d-1.png "Page 2

CONNECTIONS
Important: Ensure the rear panel power switch is in the off position whenever cha\
nging
connections. Also ensure that the power amplifier is off.
1) Connect one or more source components to the Janus inputs. Both balanced and single-
ended connections are provided for each input. A tape deck may be connected to the tape
input / output connectors. The tape output is unbuffered.
2) A turntable may be connected to the phono inputs. Never connect a high level source \...](http://img.usermanuals.tech/thumb/217/3112/w300_janus-owners-manual-1478606521_d-2.png "Page 3

4 INPUT SELECTION Press any of the five input selection buttons to select the desired input. Tape input selection will monitor the output from a cassette deck. Press PHONO to select the high gain phono preamplifier. VOLUME Volume is controlled by pressing the left side of the display glass for down, the right side for up. Each step is 1dB. BALANCE Balance is adjusted only by the remote control, by the left and right arrow buttons. It is not adjustable from the front panel. When...

Selecting an input that is configured for bypass will cause the bypass L\
ED to blink for a short
time before going to the desired input, indicating that the unit is about t\
o enter the bypass mode.
This is to allow the user time to reduce the level of the surround processor or select another input \
if there is any doubt about the safety of entering bypass mode. Pressing any button on the Janus
while the bypass LED is blinking will cause the unit to revert back to t\
he last selected input....](http://img.usermanuals.tech/thumb/217/3112/w300_janus-owners-manual-1478606521_d-4.png "Page 5

It is possible for the phono section to overload the line section. Dist\
ortion on peaks is the most
obvious indication, but sometimes it can be a less obvious compression of dynamics and an
upper midrange hardness. Simply lowering the gain of the phono section will eliminate this
problem. The selected gain is stored in non-volatile memory and will therefore not be lost even
if the power is disconnected.
The mute button is active while in the gain adjustment mode.
