19
Bluetooth
The M11S supports lots of Bluetooth codecs for both transmission and
reception, allowing for rich wireless connections.
Bluetooth transmitting
When being a Bluetooth transmitter connecting to new Bluetooth
devices (such as Bluetooth headphones, Bluetooth speakers), the M11S
needs to pair with the Bluetooth device first. Here are the steps.
1) Go to the Settings->Bluetooth menu.
2) Turn on Bluetooth.
3) Tap "Pair new device". The M11S will automatically search for and list
available Bluetooth devices nearby.
20
4) Tap the intended device to start the connection. Successfully
connected devices will be displayed on the list of Available media
devices with an "Active" prompt.
Before connecting to a Bluetooth device, you can select the Bluetooth
codec you like in the M11S. Here are the steps.

22
Audio
23
Output selection
Both PO and LO are available for 3.5mm and 4.4mm.
SPDIF OUT
The SPDIF out (Coaxial Out) supports DoP and D2P modes. In D2P
mode, PCM will be output originally while DSD will be converted to
PCM signal. In DoP mode, both PCM and DSD signal will be output
originally (Note that when outputting DSD signal, the latter decoding
device is required to support DSD decoding for normal output.)
24
Gain
There are 3 gain levels, high, medium and low. For common situations,
the low gain can help to achieve longer music experience. When using
high-impedance headphones and other similar devices, high gain can
help to achieve smoother music experience.
25
Lowpass filter mode
There are 7 different filters (internal configuration of the ES9038Q2M)
built in the M11S for your preference.
Filters are the sound effects born with the chip, which only has slight
adjustments for the sound. Here are some introductions to different
filters. These are only for reference since actual listening also has
something to do with the matched device.
1) fast roll-off,linear phase filter: Most Common filter with clean
suppression and high rejection, best for music with high transients.
Provides crisp clean highs
2) slow roll-off,linear phase filter: coherent and clear sounds, positioned
near the middle. It is suitable for classical music.
3) fast roll-off, minimum phase filter: Minimal Pre- Ringing, preferred for
Imaging and soundstage. No aliasing in frequency domain. Stronger
bass than Linear Phase,clean highs
26
4) slow roll-off, minimum phase filter: Non-Symetrical filter designed to
minimize pre-ringing. Strong punchy bass with good transient attacks
5) apodizing fast roll-off,linear phase filter: Version of Linear phase fast
roll-off filter optimized to improve pre-ringing.
6) hybrid fast roll-off, minimum phase filter: Combination of Linear-
phase and Minimum-phase. Fast transient attack, strong punchy bass,
crisp highs.
7) brickwall filter: On of the earliest designs, intended for highest
suppression possible,with high delay and pre-ringing.
Bluetooth Audio Encoder
The Bluetooth transmission takes the highest codec by default. You can
choose the highest codec supported for the Bluetooth connection by
27
this option.
Balance
If there is any imbalance between the left and right channels when
playing music, you can adjust the channel balance here. It supports
L20-R20 adjustment.
28
All To DSD
When the All To DSD function is turned on, the PCM signals will be
converted to DSD for output with sound quality further improved.
【Principle】All To DSD is mainly about switching digital signals from
PCM to DSD format. So when making digital-to-analog conversion, it
can use DSD format, enriching music styles with clearer and natural
sound quality. In addition, since the lowest format of the DSD is DSD64,
i.e. 4 times of the 44.1k/16bit (just looking at the data size), the All To
DSD function is upsampling the 44.1k/16bit audio signals. Third-party
apps also support All To DSD.
Notice: the All To DSD mode will heat up the device more seriously, and
the battery life will be relatively shortened.
Adjustable volume at LO
29
When it is selected, the volume is adjustable at LO output. Otherwise, it
is fixed at the maximum volume.
Display
The display settings consist of Sample rate display, Dark theme,
Brightness level, Night light, Wallpaper, Screen timeout, Font size,
