02/20/2023: Update ADI-2/4 Pro from DSP 30 to DSP 31. Bug fix DAC Mode: In certain situations the SPDIF input was permanently selected. Toggle Phones/Line: Several errors in assignment and function fixed. Some parameters of the settings of Phones Out 1/2 and 3/4 were not assigned correctly. Balanced mode Pentaconn: Some wrong assignments fixed. Loopback display in Status Overview screen did not work with Out 3/4. Assignment of the volume-dependent DC warning threshold of Ph 1/2 corrected.


02/13/2023: Update ADI-2/4 Pro from DSP 29 to DSP 30. Bug fix rear TRS set to 3/4 is no longer muted when Ph1/2 is plugged in. Bug fix DC detection on Line Out 1/2 affected Balanced Phones output via Pentaconn (which is Ph3/4). Bug fix remote commands were shifted by one with Dual Volume mode active. Improved: Dual Volume mode, activated via VOL and leaving the Dual Volume screen by a different key, is now sticky until it is exit in the same way - using the VOL menu and leaving it with the VOL key. Advantage: VOLUME press (toggle mode on the unit) and SEL press on the remote no longer disable the Dual Volume mode. Instead multiple presses include that mode now.


02/03/2023: Update Digiface AES to MCU 16: At Double and Quad Speed the AES Out did not work as TM FX Main Out.

12/15/2022: Update ADI-2/4 Pro from 67/26 to 70/29. Bug fix, critical: Using Pentaconn the unit can start to operate unpredictable and weired (changing cursor position, relays clicking). Bug fix: The DA filter selection of 1/2 was saved but never loaded (only NOS was remembered). Improved Expert Settings: Acceleration on setting high THD compensation values is now working also in the negative value area. Fixed: Current channel/cursor state is now stored and loaded. When plugging Pentaconn cursor moves from 1/2 to 3/4, then additionally plugging Ph3/4 cursor no longer jumps to 1/2. Dark Volume screen: When starting DSD playback, Phones 3/4 B/T line was not replaced by DSDxxx. Remote: After reset (factory default or shipping state) the option Remap Keys was set to Off instead of On. Remote: The Mute key on the remote did not mute the current (cursor selected) output, but always 3/4. Default of filters for AD/DA has changed to Sharp. To avoid confusion the options in the Phones menu, SETUP - Phones, changed from Mute v. TRS 3/4 to Mute v. Ph 3/4, and to Mute v. Ph 1/2.

Attention: After the update reset the unit: in power off state press and hold upper encoder 1 (B) and the VOL key (not VOLUME) while turning the unit on. The display will show  Reset Done .


11/29/2022: Supports new hardware revisions of some devices. Includes DriverKit compatible firmware for some devices, so that these are compatible to both Mac and Windows.

08/22/2022: Hotfix ADI-2 Pro 265/116: since version 263 the SRC did not work correctly for SPDIF and AES at Double and Quad Speed.

05/19/2022: ADI-2 DAC 78/50, ADI-2 Pro 262/115. Bugfix: A preset name consisting only of spaces caused the device to freeze. AutoRef DSD did not work correctly on devices with AK4490. Pro only: ADC set to DSD mode caused a false DC warning on the DAC part. AutoStandby now also includes signal check of the analog inputs.

04/11/2022: ADI-2 DAC 78/49, ADI-2 Pro 262/113. The option Do not load Volume did not always work as expected. Loading the Factory setup now also follows that option. B/T can now be used in both PEQ and as B/T at up to +/-12 dB. Remote Locked now allows to use the volume keys on the remote. Pro only: In Dual EQ mode a graphics refresh was missing in the Bode plot. In Dual Phones mode with AutoRef active, inserting a TRS jack into Phones 1/2 could cause a wrong dBr setting.

UFX II 23/11/14, ESS 111/107/14: TB: Made ready for DriverKit (Mac). Improved USB hub compatibility (for example Mac Studio Display). ESS DAC: low level control optimized.


01/19/2022: ADI-2 DAC 78/48, ADI-2 Pro 262/112. B/T is now adjustable in EQ as bands BB and BT if 'Load B/T with Preset' is active. More options for Auto Standby. Marker in Horizontal Level Meter. Switchable filter to avoid DC and infrasound at analog outputs. Pro only: Bugfix Digital inputs are accessible via USB again. Display - Horizontal Meter - Post FX dBu now also works for the analog input.


12/23/2021 ADI-2 DAC DSP 47, ADI-2 Pro FPGA 259 DSP 111. Horizontal Level Meter Pre FX shows OVR again. PEQ Presets: The display (lin) after a reset with Clear now disappears also if only High/Low Pass is activated. Setups: Display 'Invalid!' when loading empty setups has been changed to 'Empty'. New screen for Balance to make it easy to see the setting remotely; stop time on <C> has been doubled. Display Mode Dark better shows inactive settings. Encoder Filter: New method to prevent encoder malfunction like jumping and direction errors. Added Digital DC Protection, detecting potentially harmful DC in the digital source signal. Analog output level meters can now show dBu. B/T setting storage: The current Bass and Treble setting is now always stored in the PEQ Preset. With 'Load B/T with Preset', B/T are automatically loaded. The new option 'Swap with Preset x' allows a comfortable change of the Preset order. Selection of PEQ presets via remote and keys on the device is supported via Remap Keys. Additional display colors for the analyzer, monochrome (black / white), orange and red. The option Lock UI in the menu SETUP - Options - Display allows to lock the keys on the front and remote. Auto Standby switches the unit into standby state after 30 minutes of inactivity.

CC mode: at sample rate mismatch USB record data will be muted, the USB sample rate shown red in the Status Overview screen.

06/29/2021 ADI-2 Pro v254: In Balanced Phones mode, switching DA filters via NOS could cause sub-sample delay between left and right headphone outputs. V254 includes special re-sync routines and a 0.4 second mute pause on each switch.

04/14/2021 UFX II 22/14/8. Added mute which suppresses click noise when switching Single/Double/Quad speed while input monitoring is active. DURec: improved detection of connected USB devices with corrected error output for unusable devices. RF-64 files smaller than 2 GB can now be played. General: improved display switching when changing volumes on the host. Slightly less acceleration of encoders for better operation. Equalization of the level meter display of the phones levels at mono setting (High/Low).

03/26/2021 ADI-2 DAC DSP 35, ADI-2 Pro FPGA 250 DSP 102. All Pro: improved performance of SRC, headroom reduced to +3 dB. New option 'SRC Gain dig' to preserve digital headroom during USB recording and digital loop-through. Pro and DAC with MRC: Over display in level meters now takes actual headroom into account (+2.5 dB Line/IEM, +1 dB Phones). All DAC: When loading a setup, the current sample rate is not changed.

03/17/2021 Digiface USB: v17 supports new PCBs. Devices with V14 do not need to be updated. ADI-2 DAC FGA 35, ADI-2 Pro FPGA 249: Improved SteadyClock, filter and phase control. SteadyClock s jitter filter now operates down to 1 Hz instead of about 200 Hz, thus reduces even very low frequency input jitter efficiently.

09/17/2020 ADI-2 Pro updated to 238/98, ADI-2 DAC updated to 34/34. Current peak on power-on reduced. 

04/22/2020 MADIface Pro V 73: Click noise when switching EQ and LC removed.

03/13/2020 Digiface USB updated to 14, UFX II to 20. Digiface USB: SPDIF Channel Status incorrect at Double and Quad Speed. UFX II: Fix for receiving MIDI SysEx, issue limited to macOS. Note: Pro 98 and DAC 34 include no changes, an update from 97/33 is not necessary.

10/14/2019 ADI-2 Pro updated to 213/97, ADI-2 DAC updated to 27/33. Turning any encoder at the unit interrupts AutoDark again. DAC only: pressing one of the three Source buttons twice activates Sopurce Auto.

09/23/2019 ADI-2 Pro updated to 213/96, ADI-2 DAC updated to 27/32. Common changes: Switching EQ On/Off caused EQ band 5 to change its function. The ADAT input could activate De-emphasis for the analog outputs. New pre-mute function for PCM (click suppression on sample rate changes). ADI-2 Pro: Added M/S-Processing option to the Analog Input Settings menu. Added DIM function (Settings menu and Remap Keys). Fixed the internal mute control (broken since v193). After power-off and -on DualVolume mode was reactivated, but the individual volume settings got lost. Phones Out 3/4, Settings, Source: Removed choice USB 3/4 when in Stereo mode. Renamed Hardware/Diagnosis to SPDIF/Remap Keys. Renamed Device Mode to Device Mode/DSD. Renamed Phones <==> Line to Toggle Ph/Line to use the same name everywhere. Fixed the 32 bit clipping module for the analog outputs (Broken since v193). Fixed multiple resets when changing from 16x DSD to 8x DSD (no audible issue). ADI-2 DAC: Optimized the internal mute control. Dim did not work as expected at the Line Out when AutoRef was active. Remote: Command Mono did not work. Command VOL is now fully supported (short click mute). The display could start to flicker when using various commands in a quick, sequential order. Remapping and Remote: DA Filter showed the expected message, but in reality Crossfeed was switched. Reduced DarkScreen timeout when triggered by remote. Renamed Hardware/Diagnosis to Remap Keys/Diagnosis. Renamed Device Mode to Phones/DSD.


07/01/2019 ADI-2 DAC updated to 26/30. Offically supports third party remotes. Fixes display issue when using Balance and Bass/Treble via infrared remote. Fix: State Overview warning Emphasis did not fit the screen. Improved: Warning messages Emphasis and Non-Audio newly referred to inputs optical or coaxial.
 
06/26/2019 ADI-2 Pro updated to 193/94, ADI-2 DAC updated to 26/29. Common changes: Added phones removal to interrupt the AutoDark mode. ADI-2 DAC: The currently loaded EQ Preset stays valid after a reboot (if it wasn't modified). To make ON and OFF messages easier to recognize ON now features a light green background, OFF a light grey one, and OFF and ON are in capital letters to improves readability. Brought back Standby button to interrupt the AutoDark mode. Changed 'DIM' to 'Dim'. ADI-2 Pro: New meter options Pre-FX, Post-FX and Dual now work as expected on the analog inputs in the Global Level Meter screen. Loading a setup that had Basic mode AD/DA and then an Analog input chosen as source required to load the setup two times in a row to activate the analog input. New Remap Keys options Polarity, Crossfeed 1-5 and all DA filters did not work. Amber did not show the intended color change when in DSD mode. A specific setting in combination with Dual Linked Volume (Dual Phones On) caused an invalid Balance value of L850 after reboot.


06/07/2019 ADI-2 Pro updated to 193/93, ADI-2 DAC updated to 26/28. Common changes: Improved AutoDark behaviour. The Dark mode is now interrupted when any phones is plugged-in, by pushing the volume knob and when warning messages are shown. Quickly turning the encoder 1 to change the current channel in the I/O menu caused invalid screen content. Reduced encoder acceleration in various modes (frequency, Q ) for easier adjustment. Copying empty PEQ presets over saved ones now causes a reset of the saved preset which is then marked with 'lin' as 'linear'. Additionally EQ Preset 21, Clear, has been added as fixed linear preset for comparison and to reset others by copying it onto those. Added level meter color 'Amber' (Setup   Options   Display   Meter Color). Added option to select horizontal level meter source between Pre-FX, Post-FX or Dual. Active Mono mode is now shown in the lower taskbar. Added Crossfeed 1-5 and all DA filters to Remap Keys (Setup   Options   Hardware/Diagnosis).

Changes for ADI-2 DAC only: Bugfix: since V24 changing VOL no longer deactivated DIM and Mute. DIM is now a fully supported function and therefore available in the I/O menu and remembered by the unit over power-off and -on. New Details Top screen. This version of the Dark Volume screen lists all currently active DSP functions, including the currently loaded PEQ Preset name. New option Mute Line   Toggle Plugged (Setup   Options   Device Mode). Having plugged-in Phones and IEM, switching via long press of the Volume knob now toggles between Line (rear), Phones, IEM, back to Line (rear) and so on. A short press on the Volume knob mutes the outputs. 

Changes for ADI-2 Pro series only: Fixed DA path for proper playback of low level signals (LSB offset as discovered by KSTR). Show Vol Screen Off did not work in Dual Phones mode. Improved behaviour when a channel is in OFF mode. Improved behaviour when Phones states change during power-off. Channel select marker behaviour improved in certain cases.


02/21/2019 Updates USB of UFX II to 19. Fixes two issues in device start: delayed readout of the serial number and too late activation of the CC mode.


02/13/2019 Updates USB of MADIface XT to 191, of MADIface USB to 25. Fixes a compatibility issue (record start) with Asmedia USB controllers.



How to use:

Start fut.exe. The program will show you the current revision of your unit, and whether it needs an update or not. If so, then simply press the 'Update' button. A progress bar will indicate when the flash process is finished (Verify Ok).

If more than one unit is installed, all units can be flashed by changing to the next tab and repeating the process.

After the update the unit needs to be reset. This is done by powering down the unit for a few seconds. A reboot of the computer is not necessary.

When the update fails (status: failure), the unit's second BIOS will be used from the next cold boot on (Secure BIOS Technology). Therefore the unit stays fully functional. The flash process should then be tried again on a different computer.
