Glensound DARK8MAI MKII 8-Channel Microphone Amplifier for Dante/AES67

Share

The DARK8MAI MKII (Microphone Analog Input) from Glensound is a very powerful Dante/ AES67 network audio interface in a robust stage box/throw down style. It has eight low noise mic/line inputs which are remotely controlled by a Windows 10 app. The outputs of the microphone amplifiers are transmitted on a fully redundant Dante/ AES67 network interface.

Having eight low noise, high quality microphone inputs makes the DARK8MAI MKII perfect for transporting audio circuits from a stage or a pitch side position to a mixer or other location within an audio network.

The rugged design, PoE powering and remote control facility of the unit means that it can easily be placed and left unattended wherever audio sources are required.

Eight Audio Inputs
The DARK8MAI MKII has 8 audio inputs. Each input is on its own Neutrik 3 pin XLR socket and each input can be set to accept line or mic level inputs. Clever internal circuitry even changes the input impedance to correctly match the input type.

Low Noise Mic Amps
The very best low noise and distortion microphone amplifiers chipsets by Profusion are used in this very carefully designed pre-amp. The design of the pre-amp took over three months to develop and tailor to provide crystal clear sound unaltered by unwanted characteristics.

Mic/Line/Phantom Power
Each of the eight inputs can be individually switched to accept either a mic or line level input. The mic input can also have 48 Volt phantom power turned on/off. Input selection and phantom power settings are enabled on the Windows 10 app.

High Quality Analog To Digital Converters
The best and widest range analog to digital converters (ADC) currently available are used to make sure the digital audio on your network is as good as it possibly can be. The filter settings of the ADC can even be changed via the app.

Windows 10 App For Remote Control
GlenController, a free Windows 10 app, provides full remote control of the DARK8MAI MKII. It allows switching of input types, gain control, level monitoring and more.

Network Interface
There are 4 network interfaces on the DARK8MAI MKII. There are 2 x Neutrik Ethercon (RJ45) connectors and there are also 2 x SFP slots for customers to fit their own preferred fibre interfaces.

Redundant Network Interface
When using the Dante protocol, it is possible to set the DARK8MAI MKII to have a fully redundant network interface whereby a completely glitch free automatic redundant audio network link is provided across two of the network interfaces.

Power
DARK8MAI MKII can be powered from independent sources to provide a redundant power option. Each copper RJ45 network socket can accept PoE (this means that just one cable can carry power and audio data to/from the unit). A DC input is also provided for powering the unit from an external DC source if no PoE is available.
