Agora - AxC-AE8io

Analog input and output card with 4 IN and 4 OUT on Euroblock. It must be inserted in the slot available on the rear panel of the Agora H1 to build the audio bridge. The AxC-AE8IO provides 8 high-end analog inputs / outputs channels with Euroblock connectors.
It combines high-performance A/D and D/A conversion chips with excellent circuit design in an AxC board format for high-end fixed installation applications.

AxC-AE8IO applications:

• Perfectly meets the constraints of high-power sound reinforcement systems for professional audio applications, thanks to an intelligent design that avoids noise during switching on and off
• Fine level calibration is possible as required in many applications in professional audio systems: a digital attenuator / gain in 0.5 dB per step from -115 dB to +12 dB and 2 hardware reference level pads of + 10 dBu or +24 dBu fully controllable via software
• The attenuation gain setting and VU-meters can be monitored and controlled individually per channel, over the network, for remote management from virtually anywhere.

Applications:

• Stadiums, concert halls, exhibition venues and convention centers
• Audio broadcasting systems and pagers in museums, theme parks, resorts, transport terminals
• Live broadcasts, broadcast studios and OB vans
• Theaters, bars, pubs and discos
• Recording studios

Main features:

• 4 analog audio inputs and 4 analog outputs on one AxC board for the AuviTran Audio ToolBox platform
• High performance balanced inputs and outputs for high-end professional fixed installations
• Individual gain control for inputs and outputs
• Euroblock connectors
• Remote management with AVS-Monitor software via EtherSound network
• Dedicated control page for remote monitoring and control of all board parameters
• Dynamic range > 112 dB (A-weighted)
• THD +N < 98 dB
