Improved encoder operation experience with a new jitter elimination algorithm
Added support for BT Magic
Improved automatic input switching (In order to support BT Magic APP control in the future, I2S(bluetooth) is no longer supported in automatic input switching, needs set to I2S input source manually)
Reduced probability of an unrecognized device
Fixed MQA max volume noise
XMOS Firmware Changelog:
Improved LED display indication
Fixed MFi version display issue
Fixed iMac wake-from-sleep issue
Fixed BT Magic’s noise issue when playing back PCM768
Fixed Mac OS HID volume issue
Download XMOS Firmware:
Due to limited USB bandwidth, Tone2 Pro cannot support HID volume control and PCM768 at the same time, so these features were implemented separately in two firmware versions. Choose either the normal firmware or HID firmware for your Tone2 Pro’s XMOS chip.
Since the MCU firmware has been combined into the XMOS firmware, after upgrading the XMOS, it is necessary to replug (off then on) the power supply to enter the MCU upgrade mode, thus completing the entire upgrade process. During this time, the LED light will flash 3 times: check upgrade - upgrade - upgrade is complete.
Known Issues:
When Tone2 Pro is connected, your PC will not enter the sleep state automatically.
(We have tried to solve this problem, but the current solution will cause an error exception when switching to the next DSD track, so we have not released this update)
The Tone2 Pro may become unrecognized when a Windows 10 PC wakes up from sleep. This issue was not observed on Windows 11 nor macOS.
How to Upgrade:
For v1.2 or later firmware, please check page 6 of the User Manual: Firmware Upgrade.
For v1.0 firmware (serial number starts with 0C: or 11:), in addition to updating the XMOS firmware, the MCU needs to be updated separately.
Some device maybe meet the problem: not bitrate indication after update the v1.41 firmware.
it need to upgrade a special version vff.ff to reset default setting, and then upgrade v1.41 firmware again. Here are some devices that have encountered this situation.
I think this firmware has some problem with Tidal and USB Audio Player Pro app while MQA playback.
With max volume it has noisy and distortion sound. Please check it ASAP.
Hi jlafu,
we tested a few MQA songs through Tidal and haven’t found that noise yet, we still need to do more tests. Could you share which song you tested whit us? Also could you tell us the impedance of the headphones you are currently using?
thanks so much.
Hi jlafu,
We have fixed this issue, but we need more time to test, and V1.41 firmware will be released in the next few days.
thanks for your help, have fun!
What happens if I leave the Bluetooth module installed when upgrading?
Is the MCU firmware permanently broken? Or will there be no problem if I upgrade the firmware again?
The MCU firmware will not upgrade success. When in this state, need to disconnect the BT Magic, and then replug (off then on) the power supply, the MCU will continue to update complete.
These two situations are prohibited, otherwise will permanently corrupt the device firmware
Hi Noel.fs
After connecting to the PC, the PC cannot automatically enter the sleep state, at present. This issue may be updated in a future version. This issue is related to the HID function.
IMHO, the bass boost and widening of the sound (justo like in other portable DACs) would be wonderful additions. I find no difference between the filter modes, even listening multiple times.
I hope you can consider it for a future update.
Is there any change to input switching when using BTmagic?
I thought BTmagic would have priority over USB in sound output when Bluetooth is connected with the selection knob auto, but it works differently than I expected.
In order to output sound using BTmagic in v1.3, I2S had to be selected from the selection knob, which seems to be the same in v1.41.
