AoIP22M has been designed for broadcast, theatre and location applications. It can be used as a two-input, two-output device between analogue audio and Dante/AES67 network audio. AoIP22M can also be used as a 2-channel mic amp into Dante/AES67 with two analogue return channels from the network. The unit can be powered via PoE or via USB C.

The two analogue inputs are on XLR connections and can be switched independently between mic or line level. 48v phantom power can be selected separately per input, and is indicated as active on the front panel. Each input has the gain adjust on a small, spring loaded pot. Pushing it in releases it into the adjust position, and when the level is set, it can be pushed back flush to the front panel to avoid accidental adjustment. Each input has a three colour, 7-stage LED PPM meter to aid the setting of input gain level. Output levels can be set with different firmware to be -18dBfs, -20dBfs, or -24dBfs. AoIP22M is digitally controlled, allowing additional functionality that can be easily selected with the front panel switches. The switch function is detailed on the top panel as shown above.

A high pass filter is selectable on each input channel and can be set at 20Hz, 30Hz or 60Hz. This is particularly useful when the AoIP22M is being used as a mic amp as it reduces the audio level below the filter point. The unit also incorporates three compressor settings (Off/Soft/Hard) to allow the user to apply up to 4:1 ratio.

The output of each mic amp can be separately selected in two modes of operation: Mic In: In this mode the output is the line level of the mic input. In other words, the channel is operating as a normal analogue microphone amplifier; Dante: In this mode the output is the line level return audio from the Dante network. AoIP22M uses Neutrik Halo EtherCON connector for the network connection. This is standard XLR size and allows the connection of standard RJ45 network cables, as well as the more secure locking EtherCON plugs. The outer ring of the EtherCON shows power and data traffic via its LED ring, without the need for separate LED indicator lights.

Audio: Frequency response: 27Hz - 22kHz. Mic input gain range: 25-68dB. Phantom power: +48V. Equivalent input noise: 123.9dBu. High pass filter: 27/43/86Hz switchable.

Gain control can also be accessed via GlenController/UDP with network options including Dante or RAVENNA/AES67. A visual display positioned to the left of the front facing panel allows the user to quickly identify the operation of primary/secondary network link, main/redundant power input, and sample rate of 44.1/48/88.2/96/176.4/192kHz.

The rear facing panel hosts all I/O connectivity (with the exception of the headphone output) including analogue inputs 1-8 on 25-pin D-sub connector, inputs 9-16 on 25-pin D-sub connector, analogue outputs 1-8 and outputs 9-16 via 25-pin D-sub connector, word clock in and out on BNC connectors, RJ45 for networked control, USB-C for firmware update, dual Dante connections, dual IEC mains power inputs, and dual SFP slots. In addition, a 6-pin Phoenix style connector allows for primary and secondary alarm outputs.

Designed for broadcast, theatre and pro audio use, Glensound DARK8O features digital audio in (by way of Dante or Ravenna) and 8x analogue audio outputs by way of 3-pin XLR connection. The network link is via primary and redundant copper Ethernet or SFP fibre modules, and power is on PoE or external DC.

The front panel of the DARK8O has four LEDs that illuminate depending on the status of the link to SFP or Ethernet connection. A mini-USB connection allows the firmware of the DARK8O to be updated along with the blue identify button and reset button. Two SFP slots are provided to take optional primary and secondary SFP fibre interfaces for the network connection. Two Ethernet sockets provide primary and secondary copper Ethernet connections.

The rear panel of DARK8O has eight audio outputs from the network. Each of the eight output channels has a dedicated Neutrik 3-pin XLR plug.

Glensound DARK8ADI is an analogue to digital converter designed to connect AES3 and line level analogue audio circuits to a Dante/AES67 audio network. It has four balanced AES3 inputs and eight balanced analogue inputs on the rear panel 3-pin XLR connectors. In total, sixteen audio circuits can be sent to the Dante network from the device, with eight derived from both the AES3 and analogue inputs with the AES3 input being sent to the output when a valid AES3 signal is detected. The other eight channels being sent to the network are always derived from the four AES3 inputs.

The front facing panel of the DARK8ADI has four red LEDs and four green LEDs that illuminate depending on the status of the link – with red indicating no connection, and green indicating a successful connection. There is one 8-way female D-type connector which is an alarm status connection that will report the failure of a link status if one is detected whilst in operation. A mini-USB connection allows the firmware of the DARK8ADI to be updated, along with the blue identify button and reset button.

The rear facing panel also has two standard network data SFP sockets provided to allow redundant network connectivity if using Dante network audio protocol (SFP modules not included). There are also two standard network data RJ45 sockets provided to allow redundant network connectivity if using Dante network audio protocol, with all connections of gigabit type. The status LEDs flash to show when data is being correctly communicated with the attached switch. Also on the rear panel are eight analogue audio inputs that are electronically balanced and accept 0dB line level signals. These analogue inputs can be routed into the AoIP network so long as no valid AES3 input is detected on the equivalent AES3 channel, as AES3 has priority. One AES3 channel carries two audio channels therefore AES3 I/P 1 equals analogue inputs 1 and 2; AES3 I/P 2 equals analogue inputs 3 and 4; AES3 I/P 3 equals analogue inputs 5 and 6; and AES3 I/P 4 equals analogue inputs 7 and 8. The signals can be routed via Dante to anywhere on a network.

There are four balanced AES3 inputs that can accept AES signals up to 192kHz. These AES digital input signals always take priority over analogue inputs to the eight switched AoIP outputs. Therefore sending an input to channel 1 in both digital and analogue domains will result in the digital signal being accepted and the analogue signal being disregarded.

Two IEC mains sockets, primary and secondary accept external AC voltage of 100 – 240 VAC +/-10%. There is a non-accessible internal fuse for this input. DARK8ADI is designed to operate with either primary or secondary mains sources or both for power redundancy.

Dark1616 is a dedicated, rack-mounting, Dante Ethernet interface, designed for use in demanding broadcast environments. It has sixteen inputs and outputs, available as analogue balanced inputs and outputs, and also as eight AES inputs and outputs (sixteen digital channels). It can be used as a stand-alone interface into a Dante network, or in conjunction with a second, directly linked Glensound interface, as an audio 'snake', or for use as the network-connected or point-to-point interface to Glensound's Dante commentator units.

It has both redundant network cable connections and redundant power supplies for extra resilience, and has redundant SFP slots, providing the option to use multimode, single-mode or single-core fibre connections for additional range. It is compatible with Glensound DARK series or AoIP44 Dante interfaces when directly connected as a 'snake'.

Dante is a software and hardware solution, offering high-performance audio distribution over standard IP networks, supporting hundreds of simultaneous channels of uncompressed audio with low latency and accurate synchronization. For further information, DANTE networking basics. In a Dante network, the Dante Controller web interface controls audio routing. Any Dante input can be routed to any other output on the network, or to multiple network output points.

The four network connections of the Dark1616 can be configured as a switch. In this configuration, if the primary and secondary redundant SFP/fibre slots have been used as the network link, the RJ45 connections can be used to loop out to further local DARK units or other Dante devices that will all be shown separately on the network within the Dante Controller configuration utility.

The front panel of the 1U high, rack-mounting chassis has eight LEDs to indicate the status of the primary and redundant systems. PSU1, PSU2, primary link, and secondary redundant link all have indicators to show either normal or fault mode. A nine-pin, D-sub connector is used to relay any fault information via GPO. This can be used to trigger alarms on other systems in the event of link or power supply failures.
