Frequently Asked Questions - DIO 44 LD Systems

How to configure Dante routing on the DIO 44?

Use the Dante® Controller software (free) available on the Audinate website. Connect your computer to a network port on the DIO 44, launch the software, then route signals by drag-and-drop. The configuration is saved in the device.

How to activate 24 V phantom power on an input?

Briefly press the rotary encoder on the front panel, turn to select the desired channel, then press and hold for about 3 seconds to enter edit mode. The P24V LED flashes: turn the encoder to activate (slow flashing) or deactivate (fast flashing) phantom power, then confirm with a short press.

How to adjust input gain?

After entering edit mode (3-second press on the encoder), the gain value flashes. Turn the encoder to choose among the 4 positions: -15, 0, +15, +30 dB. Confirm with a short press. The +15 and +30 positions activate a 100 Hz high-pass filter.

What does the red SIGNAL LED mean?

The two-color SIGNAL indicators on each channel: white = signal present, red = clipping (distortion). If an LED turns red, reduce the input gain or the audio source level to avoid distortion.

How to lock the front panel to prevent changes?

Press and hold the rotary encoder for about 10 seconds. The lock symbol flashes then stays on. Only status inquiry remains possible. To unlock, press and hold again for 10 seconds.

Can I use an external power supply instead of PoE?

Yes, the DIO 44 can be powered via a 24 V DC, 1.5 A power adapter (not included, available as option). The 2-pin Euroblock connector is provided for this purpose. If you use the external power supply, the PSE+Data port can power another PoE device.

What is the minimum latency of the DIO 44?

The minimum latency is 1 ms in Dante configuration. This allows near-instantaneous audio transmission, suitable for demanding professional applications.

How to mount the DIO 44 under a table?

Use the two provided mounting plates. Remove the rubber feet if necessary. Screw the plates onto the top or bottom of the unit using the provided M3 screws, then attach the assembly under the table with suitable screws (not included). The recesses and threaded holes are designed for this purpose.

What to do if the device does not power on?

First check that the PoE+ Ethernet cable is plugged into a PoE+ compliant switch (IEEE 802.3at) or that the 24 V power adapter is properly connected. The front panel power LED should light up steadily after startup (a few seconds). If the LED flashes continuously, the device is not properly powered or has no Dante network connection.

Is the DIO 44 compatible with AES67?

Yes, the DIO 44 supports the AES67 format in addition to the Dante protocol. You can thus integrate it into audio networks using this open standard. Configuration is done via the Dante Controller software.

7 POWER SYMBOL

As soon as the DIO 22 or DIO 44 is supplied with voltage, the starting process begins. During the start-up process, the white power symbol flashes and the line outputs OUTPUT are muted. When the start-up process is completed after a few seconds, the symbol lights up permanently and the unit is ready for operation.

8 ROTARY-PUSH ENCODER

The status query and editing of the settings of the input channels is done with the help of the rotary-push encoder.

Status request: Press the encoder briefly and then rotate it to sequentially retrieve the status information of each input channel. The number of the selected channel lights up. The status of the phantom power (symbol lights up orange = on / symbol does not light up = off) and the value of the input gain (-15, 0, +15, +30, selected value lights up white) are displayed.

EXAMPLE DIO 22

INPUT 1 2 P24V GAIN -15 0 +15 +30 0,5 sec INPUT 1-2

INPUT 1 2 P24V GAIN -15 0 +15 +30

INPUT 1 2 P24V GAIN -15 0 +15 +30

The illumination of the characters is automatically deactivated if no input is made within approximately 40 seconds.

EXAMPLE DIO 44

INPUT 1 2 3 4 P24V GAIN -15 0 +15 +30 0,5 sec INPUT 1 - 4

INPUT 1 2 3 4 P24V GAIN -15 0 +15 +30

INPUT 1 2 3 4 P24V GAIN -15 0 +15 +30

INPUT 1 2 3 4 P24V GAIN -15 0 +15 +30

INPUT 1 2 3 4 P24V GAIN -15 0 +15 +30

The illumination of the characters is automatically deactivated if no input is made within approximately 40 seconds.

Edit mode: Press the encoder briefly and then select the desired channel by turning the encoder. Now press the encoder for about 3 seconds to switch to editing mode. The channel number and the abbreviation for phantom power P24V start flashing. Now switch the phantom power of this channel on or off by turning the encoder (P24V flashes in sync with the channel number = phantom power on, P24V flashes quickly = phantom power off). Confirm the selection by briefly pressing the encoder. At the same time, the currently set value for GAIN now starts flashing and you can change the value as desired by turning the encoder. Confirm the selection by briefly pressing the encoder. The digit of the next channel then flashes and you can set the status and value as desired or exit the editing mode by pressing the encoder again for about 3 seconds.

DIO 22

9 INPUT

Illuminated digits for the input channels. In each case, one of the digits lights up when the corresponding channel is selected during the status query and flashes in editing mode.

10 P24V

The orange abbreviation for the 24 V phantom power P24V lights up during the status query when phantom power is switched on and flashes in editing mode (P24V flashes in sync with the channel digit = phantom power on, P24V flashes quickly = phantom power off).

11 GAIN -15 / 0 / +15 / +30

White illuminated digits for status enquiry and for editing the channel preamplification. One of the values -15 to +30 lights up during the status query and flashes in editing mode. The values -15 and 0 are intended for line level and signals are passed on unprocessed. The values +15 and +30 are for microphone levels and signals are processed with a high-pass filter at 100 Hz.

12 SIGNAL INPUT / OUTPUT

Two-colour illuminated digits for signal detection and clip display.

INPUT: As soon as an audio signal with sufficient level is present at an input channel, the corresponding digit lights up white. As soon as one of the digits lights up red, the corresponding input stage is operated at the distortion limit. In this case, reduce the channel pre-amplification GAIN or reduce the level on the playback device so that the digit no longer lights up red.

OUTPUT: As soon as an audio signal with sufficient level is present at an output channel, the corresponding digit lights up white. As soon as one of the digits lights up red, the corresponding output stage is operated at the distortion limit. In this case, reduce the level on the source player so that the digit no longer lights up red.

13 LOCK SYMBOL

The editing mode can be locked against unauthorised editing. Press the encoder for about 10 seconds to activate the lock. Ignore the fact that the editing mode is activated after about 3 seconds. Now the lock symbol flashes for a few seconds and then lights up permanently and only the status query of the input channels can be carried out. To deactivate the lock, press the encoder again for about 10 seconds.

AIR VENTS

To prevent damage to the device, do not cover the ventilation openings on the left and right sides and on the top and bottom of the device and ensure that air can circulate freely. Covering the ventilation openings on the top or bottom of the enclosure when mounting it underneath or on top of a table is not critical, as the cooling provided by the ventilation openings on the remaining sides is sufficient.

Tip: Preferably use balanced audio cables for wiring analogue line inputs and outputs.
