LampizatOr- ATLANTIC2 TRP DAC Manual
DSD
Direct Stream Digital, also known as DSD format - this format is not new as many
people think, it is as old as digital but it wasn’t used for consumer audio or home audio
- before. It became very popular after 2010 and continues to make its way into our
homes. It is VERY different than our well known PCM format as found in our CD files,
MP3, FLAC or WAV - AIFF. It encodes the music in the data stream differently, looks
different and sounds different. It is the format in which the SACD discs were recorded
and a format in which the analog master tapes were backed up by record companies. It
is currently the format in which the master recordings are made in record industry.
In ATLANTIC2 TRP DAC - we use AUTOSENSING and automatic switch from DSD to
PCM and back. Used doesn’t need to do anything, just enjoy.
Atlantic DAC will automatically recognize and switch all DSD speed rates from normal
64 SACD format to 2x (128x) and quad 256x format all the way to 512 is supported.
Audio volume level
Tube technology allows us to set practically unlimited volume level at the output, up to
10 x higher than from a normal CD player. We have decided to adhere to one internally
set standard: the test tone of 1 kHz at -20 dB produces an output of sine wave 300 mV
AC under the amp load of 47K. Thats equivalent of circa 3 V pp. Shall this be
inconvenient for some reason – it is adjustable in the range of 0-1800 mV by just one
resistor change. The test tone is available from me via email in the form of WAV or
AIFF or FLAC or MP3 file.
Generally - we prefer the sound of the DAC with high output levels, and most amps
don’t have any problem with that. A simple potentiometer or stepped attenuator takes
care of that. Only solid state chip based preamps will saturate and distort thats why we
need to know in advance about such solid state chip volume system being driven by
the DAC. We will keep then the volume level at the “book” level of 2 V pp. Having said
that - chip volume systems and preamps with opamps belong in home theatre (cheap
one) and DEFINITELY not in high end.
LampizatOr DAC
should not be
used with opamp based preamp, no matter how good.
Because the op-amp feedback loops will remove the whole joy of music as delivered by
the tubed DAC.
