• Two analogue mic/line inputs on XLR
• Selectable 48v
• Independent gain controls
• POE & USB C power
• Up to 96k/24bit with Dante

The AoIP22M is a rugged unit, designed for broadcast, theatre and location applications. It can be used as a 2 input, 2 output device between analogue audio and Dante/AES67 network audio.
The AoIP22M can also be used as a 2 channel mic amp into Dante/AES67 with 2 analogue return channels from the network. PoE power means that only a single cable is needed to connect to the network to carry both audio and power. USB C power is also available for plug top USB supplies or using USB power bricks.
The network can operate from 44.1-96 kHz using Dante, or 48kHz on AES67.

Mic or Line Inputs
The two analogue inputs are on XLR connections and can be switched independently between mic or line level. 48v phantom power can be selected separately per input, and is indicated as active on the front panel.

Secure Gain Adjusts
Each input has the gain adjust on a small, spring loaded pot. Pushing it in releases it into the adjust position, and when the level is set, it can be pushed back flush to the front panel to avoid accidental adjustment.

7 Segment PPM Meters
Each input has a three colour, 7 LED PPM meter to help with the correct setting of input gain level.

Adjustable Line Up Levels For Worldwide Standards
Output levels can be set with different firmware to be -18dBfs, -20dBfs, or -24dBfs.
The AoIP22M is digitally controlled. This allows us to have additional functionality that can be easily selected with the front panel switches. The switch function is detailed on the top panel as shown above.

Dante Mic Amp & Analogue Mic Amp
The output of each mic amp can be separately selected in two modes of operation:
- Mic In
In this mode the output is the line level of the mic input. In other words, the channel is operating as a normal analogue microphone amplifier.
- Dante
In this mode the output is the line level return audio from the Dante network.

3 x High Pass Filter (HPF) Settings
A high pass filter is selectable on each input channel and can be set at 20Hz, 30Hz or 60Hz. This is particularly useful when the AoIP22M is being used as a mic amp as it reduces the audio level below the filter point.

3 x Compressor Settings (applicable in mic and line mode)
- Off
Clean input with no compressor.
- Soft
When set to ‘soft’ the AoIP22M uses the Glensound Referee compressor. The Referee compressor does not affect the overall dynamics of the input like a traditional compressor. It only becomes active as the input signal approaches clipping, at which point a progressively curved compressor is applied. The compression gets harder and harder up to the clip point to prevent clipping from occurring.
- Hard
A hard compressor at a ratio of 4:1.

Ethernet Connection
Halo EtherCON

The AoIP22M uses the latest Neutrik Halo EtherCON connector for the network connection. This is a standard XLR size and allows the connection of standard RJ45 network cables, as well as the more secure locking EtherCON plugs.
The outer ring of the EtherCON shows power and data traffic via its LED ring, without the need for separate LED indicator lights.

Power Options
- Power Over Ethernet (PoE)
The AoIP22M can be powered via its network connection when connected to a PoE switch. It can also receive power from a mid span PoE injector if the switch being used does not have PoE.
- USB C
A 5V, 3A USB C input can also power the AoIP22M. This can be via a USB C plug top power supply, a PC, or a USB power bank, making the AoIP22M truly portable.

The AoIP22M Case
Two Part Extruded Enclosure
Using an extruded aluminium enclosure for the body of the AoIP22M makes it extremely strong and resistant to knocks and crush damage.

Custom Made End Bumpers
The end bumpers were custom made to provide the functionality that is expected from small Glensound units:
- Protection
As the end bumpers are oversized, they provide a high degree of protection for all corners of the unit should it be dropped.
- Standing
The bumpers mean that the AoIP22M can stand flat on its end if required.
- Mounting
The AoIP22M provides fixing holes on the corners to allow mounting underdesks or on the inside of racks. These mounting holes are also often used as cable tie down points for easy temporary fixing.

Single 19" 1U Panel
The aim with the AoIP rack panel was to keep it simple and cost effective. It is a single 1U 19" panel that allows moutning of any three AoIP units.

Includes 2 Blank Panels
Remove the bumpers from your AoIP unit and use the same screws to fix into the rack panel. The further two blanking plates can be removed at any time to add a total of 3 units in one panel.
