LampizatOr- Amber-3 Manual
Additionally all our DACs have special heater circuits that slow down the inrush current
by the factor of 10 and protect the heaters from developing spots and blemishes that
cause metal erosion and eventually death (of the tube). Our circuit goes way beyond
the tube datasheet recommended protection. It extends the tube life at least double
versus the datasheet specs.
Cabling and cable handling
Just to be sure that we know what we are doing:
-
AC cable can be freely plugged and unplugged during operation. It is OK for the
DAC but NOT OK for the amplifier and speakers. A loud thump may appear after
switch off. Please turn your volume fully down before switching off the DAC.
-
SPDIF cable can be plugged and unplugged when the transport is powered off. The
DAC can be on. However doing it on „hot” when all is working – is not dangerous for
the DAC as long as the AC power supply has the GND for all products (DAC,
transport, amps).
-
Signal cables can be plugged / unplugged with the amplifier volume turned fully
down. XLR cables can be unplugged and plugged at any time because it is in their
professional nature to do so.
Please use a decent AC cable. We suggest spending around 100-200 Euro for a good
AC cable, not much more but not much less. The black AC “computer grade” cables
are not good enough for serious audio.
Please use a decent digital interconnect. In our DAC it is completely unimportant what
is the wave characteristic impedance of the cable (the famous 75 Ohms). Just use the
cable that sounds good to you. Analog as well as digital interconnects can be tried.
Best results are obtained with silver cables. Let your ears decide, not specs of the
cable.
Lampizators produces all types of cables for audio systems - you can order them
from us with confidence of tremendous value for money. To beat our cables you
need to spend 2000 Euro per one
