Welcome!
Congratulations on your purchase of this
Pathos Logos integrated stereo amplifier.
The Logos is a two-in-one machine that
combines pre- and power amplification
stages in a common chassis. The electric
network has been laid-out in a feedback-
free 'natural' way according to the funda-
mental principles of the Pathos philosophy.
The pre-amplification stage is entirely tube-
based, balanced, operates in pure class A
and is powered by a dedicated stabilised
power supply. The digital 100-step volume
control system is 100% resistive thanks to
an integrated network of high precision,
laser-trimmed resistors that guarantee
perfect inter-channel balance. The input
selector is operated through high-tech
miniaturised relays, originally developed for
very high frequency telecommunication
applications.
The output stage is true dual-mono and
outfitted with oversized transformers and
power supplies to deliver high current into
even demanding loads. This stage ensures
great energy for superior dynamics and
punch, without affecting the warmth,
naturalness and musicality provided by the
tube stage.
Finally, flexibility is provided for with 5 RCA
and 2 balanced XLR input pairs, a two-digit
LC display and fully remote controlled
functions over volume, mute and input
selection.

The amplifier must be put in a way that the current cable can be
easily accessible and the plug must have ground protection.
The amplifier must have a correct ventilation, it cannot be covered
with objects such as newspapers, towels, curtains, etc.
Minimum space between amplifier and objects are:
in height 30 cm, on sides 20 cm, in front 10 cm, behind 5 cm
Water must not be sprayed on or near the amplifier. No objects
containing liquids, such as vases, must be put on or close to the
amp.
Turning off the switch doesn't remove corrent from the amp. To
unconnect amplifier you have to remove the plug.
Warning.
