CONNECTIONS, OPERATING AND DISPLAY ELEMENTS

DIO 22

DIO 44

TERMINAL BLOCK CONNECTION FOR POWER SUPPLY

Terminal block connection for the device’s power supply. To avoid damage to the unit, please use only the original mains adapter (mains adapter optionally available).

Alternative power supply:

Ethernet switch or PoE injector with PoE+ (Power over Ethernet plus) or better.

STRAIN RELIEF

Use the strain relief for the flexible cable of the power supply unit to protect the device’s power terminal block connector and the power supply terminal block from damage and to prevent the terminal block from being pulled out unintentionally.

INPUT

Analogue audio inputs with balanced terminal block connectors suitable for both line and microphone levels. A 24 volt phantom power supply can be switched on. The poles +, – and G are intended for the balanced input signal (suitable for unbalanced cabling). Terminal blocks are included in the packaging content.

OUTPUT

Analogue audio outputs with balanced terminal block connections. The poles +, – and G are intended for the balanced output signal (suitable for unbalanced cabling). Terminal blocks are included in the packaging content. If there is no audio signal at the line outputs OUTPUT, they are automatically muted after some time. If an audio signal is detected, the mute function is automatically deactivated.

PSE+DATA (Power Sourcing Equipment)

Dante® interface with RJ45 socket for connecting further Dante® devices to the Dante® network. If the DIO 22 or DIO 44 is supplied with power via an external power supply unit, another DIO 22 or DIO 44 can be supplied with power via PoE (see connection example 2).

PD+DATA (Powered Device)

Dante® interface with RJ45 socket for connecting the DIO 22 or DIO 44 to a Dante® network. The DIO 22 or DIO 44 can be supplied with voltage via PoE+ (Power over Ethernet plus) or better.

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.

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

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

EXAMPLE DIO

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

DIO

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.

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).

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.

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.

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.

TERMINAL BLOCK CONNECTIONS

When wiring terminal blocks, please observe the correct assignment of the poles/ terminals. The manufacturer accepts no liability for damage caused by faulty wiring!

DANTE® CONTROLLER

A Dante® network is set up using the freely available DANTE® CONTROLLER software. Download the software from the manufacturer’s website www.audinate.com and install it on a computer. Connect the Ethernet interface of the computer to a network interface of the DIO 22 or DIO 44 using a network cable (Cat. 5e or better) and run the Dante® Controller software. The software has an automatic device detection function. Signal routing is done by mouse click and the unit and channel designations can be individually edited by the user. IP address, MAC address and  other information about the devices in the Dante® network can be displayed in the software.

Once the configuration of the devices on the Dante® network is complete, the Dante® Controller software can be closed and the computer disconnected from the network. The settings in the units in the network are retained. When the DIO 22 or DIO 44 is disconnected from the Dante® network, the unit’s audio outputs are muted and the power icon on the front panel starts flashing

UNDER / ON-TABLE MOUNTING

There are two recesses on the top and bottom of the enclosure, each with two M3 threaded holes, for mounting underneath or on top of the table. Screw the two enclosed mounting plates to the top or bottom using the enclosed M3 countersunk screws. Now the amplifier can be fixed in the desired position (see illustration, fixing screws not included). For tabletop mounting, the four rubber feet must be removed beforehand.

CARE, MAINTENANCE AND REPAIR

To ensure the proper functioning of the unit in the long term, it must be cared for regularly and serviced as required. The need for care and maintenance depends on the intensity of use and the environment.
We generally recommend a visual inspection before each start-up. Furthermore, we recommend that you carry out all the maintenance measures listed below every 500 operating hours or, in the case of low intensity of use, after one year at the latest. Defects caused by inadequate care may result in limitations of the warranty claims.

CARE (CAN BE CARRIED OUT BY THE USER)

WARNING! Before carrying out any maintenance work, disconnect the power supply and, if possible, all appliance connections.

NOTE! Improper care can lead to impairment or even destruction of the unit.

1. Housing surfaces must be cleaned with a clean, damp cloth. Make sure that no moisture can penetrate the unit.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used, make sure that damage to the unit is prevented (e.g. fans must be blocked in this case).
3. Cables and plug contacts must be cleaned regularly and freed from dust and dirt.
4. In general, no cleaning agents, disinfectants or agents with an abrasive effect may be used for maintenance, otherwise the surface finish may be impaired. Especially solvents, such as alcohol, can impair the function of the housing seals.
5. Units should generally be stored in a dry place and protected from dust and dirt.

MAINTENANCE AND REPAIR (BY QUALIFIED PERSONNEL ONLY)

ANGER! There are live components in the unit. Even after disconnecting from the mains, residual voltage may still be present in the unit, e.g. due to charged capacitors
