Thank you to all first adopters of Element III! We’re glad so many of you are enjoying Element III as much as we are. While EL3 is temporarily sold out, we’ve been listening to all feedback to improve firmware features and overall quality (more coming in a separate post).
Most notably, Firmware v2.2.0 or newer allows customizing the Knob Button, and eliminates the need for a UAC1 Fallback cable when connecting to consoles.
Please see How to Install an XMOS Firmware Update. Element IIIs shipping after March 25th will arrive with the latest firmware preinstalled! This includes all EL3s shipping to retailers.
*Please Note: The Knob Button ‘Toggle Output’ option requires the latest bootloader, dated 14-Mar-2022. If you own an Element III from the first batch and wish to try this feature, please reach out and we’ll be glad to enable this capability for you. You may still install v2.2.0 on an Element III built prior to March 14th and the Toggle Output option will be hidden.

Pressing down on the Volume Knob for 3+ seconds enters the Options Menu. Turn the knob to navigate up/down the options menu. Push the center of the knob to make a selection.
Available settings are described below, with default values in bold.
Default: 5 seconds, with a range of 0 (never) to 120 seconds.
- ON: LEDs will remain on while Element III is on.
- WITH SCREEN: LEDs will power off while the screen is off.
- 5 MIN STANDBY: LEDs operate as follows:
In S/PDIF mode, the LEDs will always remain on, as audio stream detection is available only in USB mode.
In USB mode, the LEDs will turn off after 5 minutes of audio inactivity. The LEDs will turn on:
(a) as soon as the USB stream becomes active again, or
(b) anytime the screen turns on with user interaction (which is true in any mode). When the screen turns off, the LEDs will turn off as well only if the USB stream has remained inactive for 5 minutes.
Consistent with 5 minute USB stream inactivity, the USB “rate” on the display will also be cleared once this standby limit is surpassed.
Note that the screen on/off is unrelated to the 5 minute standby setting. The screen power-off is related exclusively to the “Screen Timeout” option/setting.
The USB audio stream may be activated by any audio from your operating system. This feature has been tested under Win 10 and macOS. Behavior may vary with other operating systems. You can verify USB stream status in the “STATUS” menu.
- 0.5 dB
- 1.0 dB
AUTO GAIN SPEED
- DEFAULT: A progress bar is shown as you reach the 0dB threshold, providing a few degrees of hysteresis.
- AGGRESSIVE: No progress bar is shown. Transition between gain states is 4x faster at the 0dB threshold.
This option allows you to reconfigure the knob button to:
- Toggle Input
- Toggle Output [Requires 14-March-2022 bootloader]
- Mute (USB only)
- Mute (SPDIF only)
USB AUDIO CLASS
UAC2 is recommended for modern operating systems (Win 10/11, macOS, Linux, Android, iOS), providing ASIO support, DSD128 and PCM 32/384kHz playback, and ability to perform firmware updates.
Choose UAC1 to connect to legacy operating systems such as Win XP/7/8, Nintendo Switch, or PS 4/5. You may toggle between UAC2/UAC1 at any time. Element III will restart upon change, or prompt to restart. Alternatively, you may use a UAC1 Fallback cable in UAC2 mode.
MUTE INACTIVE USB
- Disabled: Preferred for Windows or macOS.
- Enabled: Preferred for Linux or Android to eliminate “alien sounds” while audio should be absent or otherwise muted.
2ND HARMONIC COMP
Default: 0, with a range of -75 to 75. Large values in either direction will increase second harmonics.
3RD HARMONIC COMP
Default: -20, with a range of -75 to 75. Large values in either direction will increase third harmonics.
Default: 7, with a range of [0:15].
This setting directly impacts jitter rejection, with the optimal value dependent on timing stability of your PC or audio source. Most audio sources produce stable audio when DPLL is set to 5. We have conservatively increased the default DPLL value to 7 in order to support a wider range of sources, especially modern 4k TVs. If you encounter stuttering, try increasing DPLL Bandwidth.
Default: OFF. Setting de-emphasis to AUTO automatically enables de-emphasis when an incoming S/PDIF stream contains such a flag, and otherwise disables de-emphasis.
- FAST ROLLOFF
- SLOW ROLLOFF
- MIN PHASE
Displays the current firmware version, USB Stream status (Active, Inactive), and internally recovered I2C Errors. This information is intended for factory Q/C checking. Please note: I2C Errors can occur from strong ESD or other interference. Element III monitors for and
automatically recovers from I2C errors. Over 17M transmissions occur every 24 hours, so it is normal to see an accumulation of I2C recoveries over time.
As the name suggests, Factory Reset clears all above settings to their default states. Upon Reset, your Element 3 will default to -45 dB volume in Headphone Output mode via USB Input, and RCA Output will default to 0 dB.
