ecler BOB-22 AES67 Digital Audio Interface User Manual

The flashing light with an arrowhead symbol inside an equilateral triangle on it is intended to alert the user of the presence of non-insulated “dangerous voltage” within the enclosure, which might be of sufficient magnitude to pose a risk of electric shock to users.
The exclamation mark within an equilateral triangle is intended to alert the user of the requirement for important operating and maintenance (servicing), for which instructions may be found in the literature accompanying the appliance.

WARNING (If applicable): Terminals marked with symbol “ ” may be of sufficient magnitude to pose a risk of electric shock. The external wiring connected to terminals requires installation by a technician, or the use of ready-made leads or cords.
WARNING: To prevent fire or shock hazard, do not expose this equipment to rain or humidity.

WARNING: A device with Class I manufacturing ought to be connected to a mains socket outlet with a protective earthing connection.
WARNING: Ecler products have a long lifetime of more than 10 years. This product must never be discarded as unsorted urban waste, but must be taken to the nearest electrical and electronic waste treatment centre.

Key Safety Directions

Read the following directions.
Keep the following directions.

Heed all warnings.
Follow all directions.

Do not use this device in proximity to water.
Clean only with a dry cloth.

Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that may release heat.

Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades, being one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, contact a qualified electrician for a replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched, particularly at the plugs, convenience receptacles, and at the point of exit from the device.

Only use attachments/accessories specified by the manufacturer.
Unplug the device during lightening sorts or when unused for long periods of time.

Refer all servicing to qualified personnel. Servicing is required when the device has been damaged in any way, such as power supply cord or plug damage, liquid spillage or objects onto the device, the device has been exposed to rain or humidity, does not operate normally, or has been dropped.
Disconnecting from mains: When switching off the POWER switch, all the functions and light indicators of the unit will be stopped, but fully disconnecting the device from mains is done by unplugging the power cable from the mains input socket, therefore, it should always remain easily accessible

Equipment is connected to a socket-outlet with an earthing connection by means of a power cord.
The marking information is located at the bottom / rear of the unit.
The device shall not be exposed to dripping or splashing liquids, and no liquid-filled objects, such as a filled up glass, shall be placed on top of the device.

Cleaning Directions

Clean the unit with a soft, dry clean cloth or slightly wet with water and neutral liquid soap only, then dry it with a clean cloth. Be careful that water never gets into the unit through any hole. Never use alcohol, benzine, solvents or abrasive substances to clean this unit.
NEEC AUDIO BARCELONA, S.L. accepts no liability for any damage that may be caused to people, animal, or objects due to failure to comply with the warnings above.

DESCRIPTION & FEATURES

BOB-22 is a digital audio interface, 2xMIC/LINE audio inputs and 2 LINE level audio outputs, Dante/AES67 (Audio Over IP) Break Out Box. It enables the conversion of up to 2 Dante/AES67 channels into 2 analogue audio LINE level output signals and vice versa, converting 2 MIC/LINE analogue audio input signals into 2 Dante/AES67 channels for transmission over an Ethernet network.
The device features PoE (Power over Ethernet) for DC power directly from PoE-enabled Ethernet switches. An optional 24VDC external PSU is available (sold separately).
BOB-22 is a generic Dante/AES67 device that can be used in combination with EclerNet / EclerPLEX / VIDA / HALO Dante devices from Ecler, or with any other third-party Dante/AES67 devices, but it is not a native EclerNet / EclerPLEX guest unit.

Main Features

Ethernet interface.
Euroblock connectors for analogue audio inputs and outputs.

2 Analogue MIC/LINE audio inputs reception.
2 Analogue LINE level audio outputs.
2×2 Digital audio -transmission and reception -channels in Dante/AES67 format.

PoE power supply ready.
Compact format.
Frontal support Half rack accessory included.

INSTALL & CONNECT

Installation

BOB-22 has been especially designed to be installed in a standard 19″ rack, taking up 1U (height) and only half the width. It includes a half rack adapter which allows two rack width media devices to be mounted on racks of 1 standard unit of measure (19”). Please refer below for the assembly instructions.
Since the device features a heat generator, it should not be enclosed or exposed to extreme temperatures.

If multiple units are installed in the same rack or in a cabinet with closed doors, it is highly recommended to install fans in their upper and lower ends for a forced air flow from the bottom up. This upward air flow will favour the dissipation of heat generated inside.

Half Rack Adapter Assembly
BOB-22 includes a half rack front adapter which allows two rack width media devices to be mounted on racks of 1 standard unit of measure (19”).

Connections

Audio input connections

BOB-22 rear panel provides 2 balanced analogue signal inputs , supporting Line or Mic levels and Phantom Power ready.
Signal input connectors are 3 position screw terminal block. The wiring is: For unbalanced connection short-circuit pin to pin − as reported on the picture.

Microphone signal: 2 channels offer a Euroblock connector for a nominal input level from -50dBV to 0dBV, with a GAIN control on the rear panel to adjust the gain.

Wiring diagram for microphones:

Microphones must be low impedance (200 to 600 Ω) and monophonic.

Each analogue input has its own gain control knob.
BOB-22 supplies phantom power for condenser microphones, individually switchable by internal jumper.

By default, phantom power is disabled (factory setting).

Audio output connections

BOB-22 rear panel provides 2 analogue outputs for line-level signals.
Signal output connectors are 3 position screw terminal block. The wiring is:

For unbalanced connection short-circuit pin to pin − as reported on the picture.

Ethernet / Dante/AES67 port

The RJ-45-type ETHERNET connector on the rear panel, allows the device to be connected to an Ethernet network.

BOB-22 allows transmission and reception of 2×2 Dante/AES67 channels.
For further information on Network Configuration and Dante routing, please refer to the chapter Network Configuration and Dante/AES67 Routing.

START-UP & OPERATION

If PoE DC power is unavailable from the Ethernet switch, please connect the optional external PSU (sold separately) to the DC IN connector on the rear panel.

To avoid buzzing, do not allow the power cable to intertwine with audio shielded cables.

The device will automatically switch on and the ON led of the front panel will light up green.

NETWORK CONFIGURATION AND DANTE/AES67 ROUTING

The routing of the digital audio signals Dante/ AES67 through the Ethernet network, as well as the network configuration of the ports Dante/ AES67 (IP addresses, mask, etc.) is managed by the software application Dante Controller.
For further information, please refer to the developer’s documentation: www.audinate.com
AES67 is enabled by default. Dante devices cannot subscribe to AES67 streams from other Dante devices.

The device comes from factory with DHCP service activated. Therefore, the unit will automatically take a dynamic IP address served by a DHCP server in the local area network where it is connected to, in case it exists. However, specific static network parameters can be configured using Dante Controller, accessing to the window shown in this example:

The default unit name, displayed as a label in Dante Controller, is factory-set to BOB-22-nnnnnnnn, where ‘nnnnnnnn’ matches the last 6 digits of the MAC address of each device. However, this name can be renamed through following window:

The routing for Dante/AES67 channel transmitters and receivers can be defined in the routing window, where all the devices with Dante capabilities detected in the network will also appear:
