PLL1
The built-in PLL circuit follows the input digital audio signal and
generates master clock. Operation in response to a wide range of
input clock frequencies is possible.
PLL2
The PLL circuit follows the input digital audio signal and, together
with the built-in high-precision crystal oscillator, generates master
clock. By using PLL circuits with different characteristics in 2 stages,
audio signal transmission jitter is reduced.
o In order to increase the performance of the built-in high-precision
crystal oscillator, it has been designed with a narrow frequency
variation range. If the clock frequency of the incoming digital
signal exceeds the tolerance of the built-in high precision crystal
oscillator, synchronization will not be possible. In such cases, set
the unit to PLL1 mode.
INT
The unit operates with the built-in crystal oscillator as the master
clock.
OUT
The unit outputs a word clock signal from its CLOCK OUT connector
and operates with clock sync.
The frequencies that can be output are 44.1, 48, 88.2, 96, 100, 176.4,
and 192 kHz, as well as 22.5792 and 24.576 MHz.
IN
The unit receives word clock signal input through its CLOCK IN
connector from a clock generator and operates with clock sync.
The frequencies that can be input are 44.1, 48, 88.2, 96, 100, 176.4,
and 192 kHz, as well as 10 MHz.
o With HS_2 USB input, the frequency that can be input depends
on the source sampling frequency.
When the source is 44.1kHz:
44.1, 88.2, 176.4, 100 kHz and 10 MHz
When the source is 48kHz:
48, 96, 192, 100 kHz and 10 MHz
DMCK
The unit receives direct input of a word clock signal that is 512
times that of the master clock rate (22.5792 MHz for 44.1 kHz or
24.576 MHz for 48 kHz) through its CLOCK IN connector from a
clock generator and operates under direct synchronization with
that clock generator.
o When playing back a CD or SACD with an Esoteric SACD transport,
only 22.5792 MHz can be input.
o With HS_2 USB input, 22.5792 MHz for 44.1 kHz or 24.576 MHz for
48 kHz can be input as the source sampling frequency, but it is
necessary to switch the clock according to the source.
