switching devices, relays introduce no alteration of the audio
signal. The drawback is that they make a clicking sound when
they are operated which we feel is a small price to pay for not
introducing any unwanted signal alteration.
As an additional refnement, the dual path volume control allows
the volume to be smoothly adjusted without any noise until the
desired listening volume is reached.
Why is a warm-up time required?
Tube heater flaments require at least 30s. after being powered
up to reach their operating temperature.
It is important that high voltage isn’t applied to the tubes during
that period to avoid arcing and damage to the cathode.
The Arcus amplifer is equipped with a soft start circuitry that
slowly brings the tubes up in temperature before it ramps up the
high voltage supply to enable a longer tube service life.
Cleaning of the amplifer surface...
•
Always switch off the amplifer and wait
30min.
to allow it cool
down before any cleaning!
•
The chassis is made of milled aluminium that has been treated
and anodized for a long lasting fnish. It can however be
scratched if not treated with precaution. Only use a dry soft
cloth to clean up the surface. More difcult to remove stains
can be cleaned using a moist cloth.
•
Never spray any liquids at the amplifer or power supply units!
