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 & distortion microphone amplifier chipsets by Profusion are used in our very carefully designed pre-amp. The design of the pre-amp took our Chief Design Engineer over 3 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 Analogue To Digital Converters

As well as the best microphone amplifiers, the very best widest range analogue 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, our 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 2 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 1 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.
