Glensound DARK8MAIR 8 channel microphone amplifier

‌8 Channel Dante/ AES67 Microphone Amplifier

The DARK8MAIR (Microphone Analogue Input Rackmount) is a very powerful Dante/ AES67 network audio interface, in a robust stage box/ throw down style. It has 8 off 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 8 off low noise high quality microphone inputs makes the DARK8MAIR 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/ Mains powering & remote control facility of the unit means that it can easily be placed and left unattended wherever audio sources are required.

Features

Eight Audio Inputs

The DARK8MAIR 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

The free windows 10 app provides full remote control of the DARK8MAIR. It allows switching of input types, gain control, level monitoring and more.

Network Interface

There are 4 network interfaces on the DARK8MAIR. 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 DARK8MAIR 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

DARK8MAIR can be powered from 4 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).  For extra redundancy there are 2 inbuilt wide range switch mode power supplies each with their own IEC inlet.
