Analogue Inputs & Outputs
Two analogue inputs and two analogue outputs presented as full size 3 pin XLRs, The mic inputs are independently selectable mic/48V/line. So the DARK22M is more like 2 x 1 channel interfaces as each side can be configured separately. A dynamic mic input on input 1 and a phantom power mic on input 2? No problem.

USB Inputs & Outputs
The DARK22M is also a bi-directional USB to Dante converter too. This will happen in parallel to the analogue audio connections. It can also be set as a bi-directional USB to analogue converter. The addition of USB C really adds useful options.

Audio Processing
Where the DARK22M really sets itself apart is in audio performance. You see, it started life as the DARK8MAI – an 8 channel mic amp. This means that the resources of the DARK8MAI are still available – namely an 8 channel analogue to digital converter. Glensound's design engineer Alex Clarke was able to utilise these ADC channels in a rather clever way. By sending each input equally across 4 x ADC inputs, then combining them in the ADC. When you divide by four, you end up with the same level, but the noise cancels out, resulting in a much improved signal to noise ratio and dynamic range. This has resulted in the mic inputs on the DARK 22M being just about the cleanest and brightest of any network mic amp available.

Further DSP Options
As a DSP device, further dynamics are available. By default, it includes Glensound's well known Referee compressor system. This is a compressor curve that only affects the audio input just prior to clipping. A graduated compressor, that is much subtler than a hard limiter, but with the benefit that it will prevent the input from clipping.

Network Connectivity & Redundancy
Network options on the DARK 22M are also very powerful. There are a primary and a secondary ports on copper RJ45 sockets, and, primary and secondary ports via your choice of SFP fibre modules. The SFP ports allow all choices of single mode, multi mode, or single fibre bi-directional modules. These can be configured in redundant mode, or a switched mode, basically turning the connections into a 4 port switch that can be used for daisy chaining other network devices.

Network Interfacing
Typically with low channel count units, devices are fairly basic, and in the Dante world this would mean the basic Ultimo module, and the associated limitations of a 100MB network interface. This is fine on entry level units, but the DARK22M is not an entry level unit. The DARK22M features the full fat Brooklyn 3 module, with 1GB network interface and its ability to happily act as the master clock on a large network. So although it is low channel count, it has high specification networking not normally found at this level.

Control
The input type and gain level can be set directly on the unit itself. The DARK22M is also part of GlenController, the Glensound remote control app. This means input type, input gain, and level monitoring is available via remote control.

The DARK22M uses UDP for remote control and the command list is available. This means if you are using a dedicated control app that can generate UDP commands (and most can) then your choice of remote will also be able to control the DARK22M.
