MARK LEVINSON No30.5L |
2,800,000yen(1994 release) |
The digital analog converter which supplied the
newest digitech to No30L and attained further high-quality sound-ization.
Each power source of a music signal and ± and the four-layers substrate
which made each line of the grounding separate, respectively are adopted, and
source impedance is reduced, and also the occurrence of time-base distortion is
suppressed by k which improves a transient.
The Jitter is reduced to 20
or less @Kpses by custom-made VCXOs (Voltage Controlled Crystal Oscillators).
The 24-bit digital filter and the custom-made 20-bit dual digital analog
converter were adopted, and 20 bits of full D-A conversion is realized.
Two digital inputs by an RCA termination are carried.
The
source-name input from the front panel is possible.
It can upgrade from
No30L.
