Glensound AoIP-4I Milan | Four Audio Inputs To An AVB/Milan Network

The Glensound AoIP4I Milan is packaged in a small & rugged format and designed for outside broadcast, theatre and location applications.

Both the AoIP4O Milan and AoIP4I Milan units are designed to easily and quickly interface existing analogue equipment to AVB/Milan network audio systems. Being powered by PoE means that only one cable needs to be connected to the network to carry both audio and power, providing flexibility and saving time on installation.

The AoIP4I Milan provides 4 balanced analogue audio inputs to an AVB/Milan audio network. 

Robust proven construction techniques, a simple reliable interface and excellent specification will help make your technician’s life hassle free, whilst the low cost and long asset life will keep the accountant satisfied.

PoE Powering
For ease of setup only 1 single cable is needed to transport both power and audio to the AoIP units. The network cable carrying audio can also power the device using standard Power Over Ethernet (PoE) technology when connected to a suitable network switch or to a mid span PoE injector.

EXTERNAL POWER INPUT
An industry standard USB C connector is used for powering the AoIP units from an external power source.  This could be a plug top power supply or a USB battery pack.

REDUNDANT POWER
If both PoE and USB C power sources are connected then power supply redundancy is automatically enabled, meaning that either one of the power sources can be lost and the AoIP unit will continue working.

POWER ON LED
A bright blue rear panel LED indicates that the device is turned on.

RUBBER FEET
The AoIP units are supplied with rubber feet so if the AoIP4I Milan is to be sat on a desk or the back of a workbench, then the rubber feet are fitted to stop it sliding around.

RACK MOUNTING
The front and rear bumpers can be removed and the AoIP4I Milan can be rack mount using the AoIP/RK rack kit.  This is a low cost mounting panel that can mount up to 3 of the newer design MkII AoIP units in a 1U 19" rack.

NEUTRIK XLRs
For audio integrity and reliability we only use high quality gold plated Neutrik XLRs.

FULLY PROTECTED ELECTRONICALLY BALANCED CIRCUITS
Not all electronically balanced audio circuits offer the same performance and reliability. With many years of specific broadcast audio experience, we’ve designed exceptionally robust and noise free circuits that have been proven to be best in class time and time again.
