Power ON/OFF
Long press the power switch to power on/off.
Analogue volume control
Warning: Due to the high power of xDSD Gryphon, always start at a low volume
level, so there is no risk of damage to your headphones or your hearing. iFi
audio is not responsible for any hearing or equipment damage from misuse.
Menu settings
I) Digital filter
The following 3 digital filters are available:
‘BP’ Bit-Perfect, no digital filtering
GTO’ Upsampled to 384/352kHz, minimum filtering, no pre-ringing, minimum
post ringing
‘STD Modest filtering, modest pre and post ringing
II) Screen Brightness
Off Sleep mode. If no operation is performed within 10 seconds, the
display will turn off.
High High brightness mode. If no operation is performed within 10
minutes, the display will dim to low brightness.
Low Low brightness mode. The display brightness always remains low.
III) Volume Limiter
| Off | Volume max 106, short press once in Mute mode volume jumps to 79 |
|---|---|
| 95% | Volume max. 100, short press once in Mute mode to 75 |
| 80% | Volume max. 86, one short press in Mute mode to 64 |
| 60% | Volume max. 66, one short press in Mute mode to 49 |
IV) Volume Sync
Turns the volume sync on / off. It is on by default.
V) Volume Soft Ramp
Turns the volume gradient on / off (the volume ladder changes for 2S). It is
on by default.
VI) BT voice prompt
ON/OFF mode, turn on/off Bluetooth voice announcement.
VII) USB dual port charge (Item 15. USB-C input)
‘ON’, this port can be used for charging.
‘OFF’, this port is for signal input only.
VIII) Factory Reset
Select Yes to perform a factory reset, the device reboots after a successful
operation.
Warning: A factory reset will erase all remembered Bluetooth addresses;
digital filtering default STD; Bluetooth voice announcement On; The default
screen brightness is High; the default USB charging is Off; the default
volume is -21dB; the default factory reset is NO.
XSpace Matrix LED
The space Matrix(on/off ) recreates a holographic sound field.
It is a pure analogue signal processing circuit designed for listening to
headphones as if one was listening to speakers. This addresses the ‘music
inside the head’ sensation, which makes for uneasy listening.
XBass II LED
XBass II is an analogue circuit designed to ‘add back’ the lost bass response
for a more accurate reproduction of the original music.
Tip: Sonically-hindering DSP is NOT used for XBass II nor XSpace matrix
systems. They use the highest-quality discrete components and operate purely
in the analogue domain. Hence all the clarity and resolution of the original
music is retained.
Settings
Cycles between:
Off > XBass II > XSpace > XBass II and XSpace (short press)
Menu settings (long press)/Return to Home (short press)
Input selector/Bluetooth pairing
This button cycles between the following inputs:
USB > Bluetooth > S/PDIF > Line (Balanced 4.4mm/S-E 3.5mm)
Note: Please select the input channel according to your audio source
input mode. For example, you need to switch the input channel to ’USB’ when
using the USB input.
The xDSD Gryphon receives Bluetooth signals via aptX, aptX HD, aptX Adaptive,
aptX LL, LDAC, LHDC/HWA, AAC and SBC.
Bluetooth pairing
When the Bluetooth input is selected, the Bluetooth icon in the display will
flash and search for a previously paired device. If a stored device is not
found, it will automatically enter pairing mode and flash. Press and hold the
button (1s) to enter pairing mode until the Bluetooth icon flashes. To pair,
find the ‘iFi Hi-Res Audio’ Bluetooth device from the nearby devices list on
your phone. The xDSD Gryphon can store up to 8 paired Bluetooth devices.
OLED display
The OLED display shows the audio format, sampling rate, volume, input mode,
XSpace/XBass II and battery level.
XBass II mode adjustment
Research into headphone frequency response showed that a purely flat response may not be correct. Our long-present XBass fits the profile of the low- frequency correction required. However, it was also shown that a certain amount of upper midrange boost is needed to give many headphones a more ‘natural’ sound. This upper midrange region is usually called the ‘presence’ region; we have used this term to indicate the upper midrange correction. In the xDSD Gryphon, XBass II (or perhaps better HPEQ) can be selected to have either Bass + Presence correction, only Bass or only Presence correction.
USB-C (5V) charging input
For charging only. Due to the very high-power nature of xDSD
Gryphon, it will take ~12 hours and ~6 hours for a standard and high-powered
charger, respectively, to fully recharge.
Tip: When the xDSD Gryphon is off and a 5V USB power supply is detected, the
LED will change colour to show the various states of charge (see next
section).
Tip: We advise you to charge the xDSD Gryphon switched off. You can listen to
music while charging, but it may take longer to be fully charged, depending on
the volume level and the headphones used.
Tip: The xDSD Gryphon may be slightly warm to touch when it is simultaneously
in use and being charged.
LED for Battery Status
| LED | Status |
|---|---|
| Green* | > 85% |
| Yellow * | ≤ 85% |
| Red (flashing) | ≤ 10% |
*The battery status LED will flash during charging, and the LED will go out when fully charged.
USB-C input
Connect your phone to the xDSD Gryphon with a Lightning to USB Camera Adapter
(Apple) or USB On-The-Go (OTG) cable (Android). When using other audio
sources, please connect with a USB cable. This USB-C port is intended for data
transfer only, but it can also be configured to charge the battery. Please see
item 6 – Menu settings, (VII).
Tip: For Apple iOS and Android devices, please use battery power on the
xDSD Gryphon, otherwise you may receive error messages from your device.
Note: For use with PC it is necessary to download drivers.
Tip: For the required driver and all the latest firmware updates please
refer to our website: www.ifi-audio.com/download-hub/
S/PDIF 3.5mm Coaxial/Optical input
When USB-C (item 15) is not used, connect to a Coaxial/Optical cable (through
a Toslink Mini-Plug).
Tip: a Toslink Mini-Plug to Toslink adaptor is required for connecting a
Toslink optical cable.
Balanced 4.4mm line input/output
a) Output (variable) – when the input mode is USB, Bluetooth or S/PDIF
b) Input – when the input mode is Line
Single-ended 3.5mm input/output
a) Output (variable) – when the input mode is USB, Bluetooth or S/PDIF
b) Input – when the input mode is Line
iEMatch switch
iEMatch reduces the output level so that even the most sensitive In-Ear- Monitors (IEMs) can be matched to the xDSD Gryphon.
| = 3.5mm headphones
---|---
= off
= 4.4mm headphone
Tip: The xDSD Gryphon or the headphone will not be damaged if the iEMatch switch is adjusted incorrectly, but the attenuation level will not be correct.
