Agora - AxC-AX4O

High-end 4-channel analog output board with XLR connectors. It must be inserted in the slot available on the rear panel of the Agora H1 to build the audio bridge. It combines high-performance D/A conversion chips with excellent circuit design in an AxC board format for high-end fixed installation applications.

Applications AxC-AX4O:

• Live concerts and recording
• Live broadcast studios and OB Vans
• Theaters, bars, pubs and discos
• Recording studios
• Fixed installations
• Stadiums, concert halls

Main features

• 4 high quality balanced outputs with dynamic range > 115 dB (A-weighted) and THD +N < -100dB
• Professional XLR male connectors
• Digital attenuation in 0.5dB steps from -115dB to +12dB and two hardware reference level pads of +10dBu or +24dBu, all fully software controllable to allow fine-tuning to address a wide variety of professional applications
• Remote management via
• Attenuation gain setting and VU-meter can be monitored and controlled individually per channel via network for remote management virtually anywhere
• Individual gain control of each output
• An intelligent internal design to reduce noise during startup and shutdown, meeting the usage constraints for high-power sound reinforcement systems
