DAC / Preamp / Headphone Amplifier
User's Guide
Overview
"Cyan" can be equipped with two different core modules, one is PCM digital analog conversion module, and the other is DSD
digital analog conversion module. The type of core module determines the internal digital-to-analog conversion method.
However, another non-source digital analog conversion method can be supported by the internal SRC (Sampling Mode
Conversion) function. Please refer to the SRC section below for details. Optional PCM module –The internal source digital
analog conversion mode is PCM mode. When receiving DSD data, the internal will automatically convert to PCM and then
perform digital analog conversion. Due to SRC capacity limitations, the maximum can only receive DSD256. Optional DSD
module –The internal source digital analog conversion mode is DSD mode. When receiving PCM data, it will be automatically
converted into DSD and then digitally simulated. Since the DSD cannot perform digital volume control, the “green” volume
setting will be disabled and the output level will be fixed at the highest after installation of the optional DSD module. At the
same time, since the volume control cannot be performed, the headphone amplifier will be automatically turned off to prevent
the excessive volume from damaging the headphones.

Settings
Settings can be applied without the remote control. This can be done by using the multi-function
knob on the front panel of the DAC.
In the default mode, rotate left and right to set the volume, short press the knob to unmute/mute. Press
and hold the knob to enter the setting mode. Press and hold the knob again to enter the next setting
mode. In the setting Mode, rotate left and right for the corresponding settings.
The order is:
“IN – Digital Input Settings”
“Out – Analog Output Settings”
“FMODE – Sample Mode Settings”
DISP –Display Brightness Settings”
Volume settings
The adjustable volume maximum is 100dB, adjustable by 0.5dB per step/increment. When the digital
volume attenuation function is turned off, this is the through mode.
Digital input settings
Select the digital source signal in "USB", "I2S", "COAX", "AES", "OPT".
Analog output settings
LINE –Line output, output on the single-ended and balanced line ports on the rear panel.
HP-LO –Headphone low-impedance output, single-ended and balanced headphone output port on the
front panel for headphones below 100 ohms.
HP-HI –Headphone high-impedance output, single-ended and balanced headphone output port on the
front panel for headphones with 100 ohm impedance or more.
Sampling mode setting Divided into two types, NOS mode and OS mode. For the selection of NOS mode
and OS mode, please refer to https://kitsunehifi.com/nosvsos/
Display brightness settings
Set the brightness of the display, a total of 6 levels of brightness. The lowest level is to completely turn off
the display.
Internal SRC (sampling rate conversion)
Optional discrete PCM module, due to SRC chip limitations, supports DSD256 when receiving DSD
signals. If using the optional discrete DSD module instead of discrete PCM Module, the maximum support
would be DSD512 and is due to the fact that SRC is not required and all DSD is processed via the discrete
DSD module. See details below:

DSD Convert DSD to PCM

I2S Digital Input
LVDS differential transmission mode
The Physical interface is the same as HDMI and an HDMI cable can be used. However, the electrical
signal it transmits is I2S protocol, not the audio and video signals of the conventional HDMI. Please do NOT
attempt to use HDMI devices with I2S Devices as damage may occur, ie. bluray player, TV etc.
NOTE: Always have both devices powered off when plugging in or unplugging HDMI I2S cables.
