The Glensound AoIP22M is a rugged unit, designed for broadcast, theatre and location applications. It can be used as a 2x input, 2x output device between analog audio and Dante/AES67 network audio. It can also be used as a 2-channel mic amp into Dante/AES67 with 2x analog 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 44.1kHz - 96kHz using Dante, or 48kHz on AES67.
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 color, 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 & analog 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 analog microphone amplifier.
- Dante: In this mode the output is the line level return audio from the Dante network.
Three 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.
Three 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
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.
