LampizatOr- ATLANTIC2 TRP DAC Manual
The TOSLINK connection
Is toslink bad or not ? That is the question. Like everything in life - it can be bad or it can
be good.
By using own experiments and oscilloscope observations we concluded, that Toslink is not
bad and not inferior to RCA SPDIF if implemented properly. Toslink is EXTREMELY
demanding about the power supply quality. That’s why we build for toslink separate
dedicated power supply and with this supply the response is instantaneous and there is no
deformation of square wave. Usually Toslink ports are installed in cheap low end gear and
the power supply to Toslink is completely neglected. Not in LampizatOr DAC. If you have
Toslink in your DAC you can be sure it will sound good and not degrade the sound. Of
course providing that the transmitter part of the link is at least semi decent.
NOTE: All Apple products which have headphone output (iMac, MacBook, Power MAC,
MAcMini, iPhone, iPad, iPod) - have a secret toslink transmitter hidden inside that port.
Just buy the special cable - Toslink Minijack and when placed in the headphone output of
an Apple product - will emit light with SPDIF in it. That is a very good way of using MAC
computers as transports.
USB playback
USB data requires installation of additional converter
module to convert the “packet” data into a steady i2S
stream. Our asynchronous converter has internal RAM
and two own clocks and own power supply and own
power transformer secondary winding.
The USB module requires a driver for Windows to
recognize it. MAC OS and LINUX work without any need
for extra drivers.
We use three vendors of USB modules:
For ATLANTIC2 we use “ JL” USB module: the driver is at:
http://www.jlsounds.com/drivers.html
Our USB converter is capable of working with 32 bit files with 768kHz signal frequency.
Only USB2 rated cables will work well.
USB cables with ferrite filters (the “thingie” on the cable ) will not work.
