DPLL
MIN ~ MAX
(A total of 15 kinds, the default is 7 kinds. The larger the number is, the stronger the range
to adapt to jitter, and the smaller the number, the better the performance against clock jitter.)
Volume control enable or disable.
Vol Fixed : In this mode, volume is fixed on max output level, and the M500 MKII
will ignore the volume operations.
Vol Variable: In this mode, volume can be adjust by remote controller, and make
M500 MKII a pre-amplifier.
PRE MODE
Instructions
This DPLL setting is a special function of ESS series products. It can adjust the internal
DPLL digital phase locked loop circuit Bandwidth, so that the chip achieves a balance
between anti clock jitter and input tolerance.
Its function:
When the clock stability of the input signal is good, this value can be reduced,
so that the clock performance of the system is better;
When the clock stability of the input signal is not good, the sound may be inter-
rupted. Increase this value can avoid the sound interruption! Especially when
using TV as signal source!
M5OO MKII
NORMAL MODE
NORMAL mode, only use the digital receiver chip (DIR) to process the SPDIF signal,
used in most occasions, in this mode supports DoP playback
.
PROCESSOR MODE
PROCESSOR mode, in this mode M500 MKII will use the XMOS processor to process the
optical/coaxial signal, so that it can have more powerful computing power and can
handle various complex tasks including MQA, DoP,At this time, the system can support
MQA full decoding, MQA-CD, DoP64.
Note: do not switch this mode frequently, try to restart the machine after switching this
mode, otherwise it may cause output noise.
SPDIF MODE
This setting is only valid for optical/coaxial interfaces which using SPDIF protocol;
