Remote control

The miniDSP Flex HT has the following options for remote control of key runtime functions.

Using the miniDSP remote

The infrared remote control provided with the Flex HT controls all key runtime functions.

Stock miniDSP remote control


Put the Flex HT into standby and take it out again.


Mute and unmute audio output.


Reduce or increase the volume. Each press changes the volume by 0.5 dB. Holding down a button will accelerate volume change to 3 dB steps.

Media control
Have no effect with the Flex HT.

Dirac Live

Enable or disable Dirac Live filtering. Dirac Live filtering will be effective only on presets for which Dirac Live filters have been loaded.

Source selection

Cycle through the available input sources in order: TOSLINK, SPDIF (coax), USB, HDMI (eARC).

Preset (1 through 4)

Switch to the selected preset. It will take a few seconds for the preset selection to complete while the processor loads the new filters from its flash memory into the DSP.


The miniDSP Flex HT responds to HDMI CEC (Consumer Electronics Control) commands. The following functions of the Flex HT will be controlled by the handheld remote control units of the connected television and source device, provided that CEC is supported by and enabled on both:

  • Standby on/off
  • Volume
  • Mute

The following functions of the Flex HT will not be controlled by CEC. You will need to use the miniDSP remote (or front panel) for these:

  • Preset selection
  • Dirac Live on/off
  • Source selection (on the Flex HT)


Note that the miniDSP remote does not control the connected TV or source devices.

HDMI CEC is always enabled on the miniDSP Flex HT. Make sure that it is also enabled on the TV and source.

Enable CEC on the TV

The connected TV will usually have a setting to enable CEC. Here is one example. In this case, we found the setting in the "General" area of the TV's settings, under "HDMI Settings".

Set TV to enable CEC

Enable CEC on the source device

A connected source device will likely also have settings for CEC. For the Apple TV 4k, for example, we needed to set "Control TVs and AV Receivers" to On. This enabled standby on/off.

To enable volume control from the Apple TV's remote control, we also needed to change the "Volume Control" setting to "TV via IR". If you have a different source device, you might need to try different settings to find the correct one.

Using a third-party programmable remote

A third-party programmable remote can be used with the miniDSP Flex HT. See this page on our support site for the codes to use:

Programming a Logitech Harmony remote

The miniDSP Flex HT can be used with a Logitech®️ Harmony®️ remote. The same functions as the stock remote are programmed into the Harmony database. In addition, you can set up buttons for direct input source selection (instead of cycling through input sources).

The procedure is as described in the application note linked below, except that you should select "minidsp flex" as the device instead of "shd".

Android/iOS control app

miniDSP Android/iOS control app

With the addition of a miniDSP Wi-DG Wi-Fi to USB bridge, the miniDSP Flex HT can be remote-controlled from a phone or tablet running Android or iOS (iPhone/iPad).

If the USB port is being used for iOS/Android app control via the Wi-DG, it cannot be used for USB Audio streaming.
