INTRODUCTION

Part of the TICA ^® series, the DIO 04 is a four output Dante interface that delivers the capabilities that audio and AV professionals really need. Equipped with four balanced outputs to connect to any analogue audio device such as power amplifiers Signal presence lights on each channel speed installation and fault-finding.

Power from any PoE+ network switch or use the optional, external power supply. Since it comes with two Dante networked ports, you can daisy chain devices together. It also works as a PoE+ injector: if you use the external power supply, you can power one further networked device in the chain.

It's tiny form factor (106 x 44 x 222 mm) and included mounting plates allow it to be installed discreetly behind screens or under tables. Alternatively, it fits into 1/3 19 inch rack. Use the optional rack tray to slot up to three TICA® DIO series products alongside each other and build a system to your exact requirements, using minimal rack space.

Terminal block connections on the analogue outputs make wiring easy.

The perfect solution for professional installers wanting to interface into Dante equipment.

Dante Domain Manager and AES 67 compliant.

FEATURES

• Four output Dante interface
- Connect Dante to line level audio equipment
• Terminal blocks for all analogue connectons
• Signal indicators on each channel
- Use PoE or an external power supply
- Use as a PoE injector to power another networked device
• Daisy-chain Dante devices together

CONNECTIONS, OPERATING AND DISPLAY ELEMENTS

OUTPUT 3 4 1 PSE+DATA PD+DATA Dante® 1 24V DC === 15 A

1 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 power supply unit (power supply unit optionally available).

Alternative power supply: Ethernet switch or PoE injector with PoE+ (Power over Ethernet plus) or better.

2 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.

3 OUTPUT 1 - 4

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 1 to 4, they are automatically muted after some time. If an audio signal is detected, the mute function is automatically deactivated.

4 PSE+DATA (Power Sourcing Equipment)

Dante® interface with RJ45 socket for connecting further Dante® devices to the Dante® network. If the DIO 04 is supplied with power via an external power supply unit, another DIO 04 can be supplied with power via PoE (see connection example 2).

5 PD+DATA (Powered Device)

Dante® interface with RJ45 socket for connecting the DIO 04 to a Dante® network. The DIO 04 can be supplied with voltage via PoE+ (Power over Ethernet plus) or better.

SIGNAL 7 OUTPUT 1 2 3 4 DIO 04

6 POWER SYMBOL

As soon as the DIO 04 is supplied with voltage, the starting process begins. During the start-up process, the white power symbol flashes and the line outputs OUTPUT 1 to 4 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.

7 SIGNAL OUTPUT 1 - 4

Two-colour illuminated digits 1 to 4 for signal detection and clip display.

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.

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.

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 computer's Ethernet interface to a network interface 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 04 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)

DANGER! 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.

NOTE! There are no assemblies in the unit that require maintenance by the user.

NOTE! Maintenance and repair work may only be carried out by specialist personnel authorised by the manufacturer. In case of doubt, contact the manufacturer.

NOTE! Improperly performed maintenance work can affect the warranty claim.
