Front and rear panels¶
Basic operation¶
The front panel and rotary encoder provide access to the key features of the miniDSP Flex HTx. These can also be accessed with a remote control.
-
To change the volume, rotate the encoder. The volume changes in 0.5 dB steps. Minimum volume is -127.5 dB and maximum volume is 0.0 dB.
-
To select a preset, press the encoder knob once, then rotate until the desired preset number is displayed. Either press the encoder knob again or wait for a second. The display will show "Pls wait..." while the new preset is being loaded, and then return to normal.
-
To select an input source, press the encoder knob twice, then rotate the encoder until the desired input source is displayed. Either press the encoder knob or wait for a second and the display will return to normal with the new input selected.
-
To turn Dirac Live filtering on and off, press the encoder knob three times, then rotate the encoder knob until the desired selection (on or off) is displayed. Either press the encoder knob or wait for a second and the display will return to normal with the Dirac Live status:
- To mute output, press and hold the encoder knob. When the display changes to show "Mute?," release the knob. To unmute, repeat this procedure.
- To put the Flex HTx into standby, press and hold the encoder knob. When the display changes to show "Standby?," release the knob. To take it out of standby, press the encoder knob.
Tip
All these operations can also be performed with the remote control.
Rear panel connnections¶
Warning
Apply power to the miniDSP Flex HTx only after all input and output connections have been made.
-
Analog RCA inputs. Connect an analog source here using RCA connections. The maximum input voltage is 2 Vrms.
-
Analog balanced inputs. Connect an analog source here using balanced TRS connections. If required, XLR to TRS adapter cables are available to purchase together with the Flex HTx. The maximum input voltage is 4 Vrms.
-
Trigger out. Connect this output to a trigger input on other equipment to turn it on and off. See also Trigger output timing.
-
HDMI ARC/eARC. Connect to an HDMI eARC/ARC source.
-
DC power. The supplied 12 VDC power supply includes a set of interchangeable power pins for USA, UK, Europe and Australia. Fit the correct pins for your country. Connect the DC plug to the 12 VDC power socket.
-
USB port for control and audio streaming. Connect to an available USB port on your computer. This port can also be connected to a network streamer with USB output for audio playback.
-
Digital inputs. Connect digital sources here using optical (TOSLINK SPDIF) or coax (RCA SPDIF). Sample rates from 32 up to 216 kHz are supported.
-
Analog RCA outputs. Connect equipment such as power amplifiers and subwoofers using RCA connections. The maximum output voltage is 2 Vrms.
-
Analog balanced outputs. Connect equipment such as power amplifiers and subwoofers using balanced TRS connections. The maximum output voltage is 4 Vrms (balanced). If required, TRS to XLR adapter cables are available to purchase together with the Flex HTx.
