12 V
— 12 Volt d.c. input, tip is positive, ring is negative. The supplied power adapter converts
120 Volt a.c. main power to 12 Volts d.c. at 500 mAmps maximum. The power plug has a
1.3mm inner diameter.
Rear Panel Controls
Reset
— This recessed push button reboots the processor in the AudioMate 360. Depress
using a pen or any object with a small tip. The length of time that it is held depressed
determines the type of reset:
Quick Reset – A momentary press performs a simple reboot.
Factory Reset – To reset the unit to its factory-default configuration press and hold the
Reset pushbutton until the OK light goes from AMBER to GREEN. While the AudioMate
360 is awaiting an address from a DHCP server this could take as much as 60 seconds. In
order to ensure that the device loads factory default settings the Reset button must be
held this entire time, until the OK light changes from AMBER.
Installation
Network Considerations
In the typical AudioMate installation all endpoints are contained entirely within a corporate
LAN, or participate via a WAN link, either unicast through a VPN or an engineered MPLS
network, for example. It is preferable that all routers serving network segments that
connect AudioMate endpoints be configured to route multicast streams. This can smooth
implementation of multicast systems in general, and the deployment of AudioMate
Communicator remote control soft consoles in particular.
Multicast is used to allow multiple endpoints to share one stream of audio packets, thus
reducing bandwidth consumption. However, while multicast streams typically pass
seamlessly through Ethernet switches, they are typically blocked by most routers unless
proper preparations are made to accommodate multicast. It is a near certainty that multicast
streams will not flow through most Internet routers. Therefore, unicast addresses are
acceptable for use in the AudioMate 360 line of IP gateways.
Bandwidth Consumption and CoDecs
The G.711 codec (encoder/decoder algorithm) consumes approximately 84kilobits/second
per stream. More aggressive codecs consume less bandwidth, but their output audio
is typically of lower quality. Some codecs perform poorly in environments with high
acoustic noise near the microphone. Narrowband IP links might require a more aggressive
codec, while endpoints on your LAN will likely do well with the G.711 codec. Because the
AudioMate Media Server can perform transcoding between coding algorithms you have the
opportunity to optimize bandwidth usage versus audio quality.
Electrical Considerations
The AudioMate 360 gateways are powered by 12 Volts d.c. which can be provided by the
provided plug-in power supply or by a 12 Volt battery with float charging system. In either
case, the power must be clean and free of a.c. noise components and interruptions. The
supplied power module should be plugged into an uninterruptible power supply (UPS) for
trouble-free service. If a 12 Volt battery/charger system is used, the charger must keep noise
to less than 12mVp-p.
