AxC-AX4M – 4 Mic/line inputs on XLR

The AxC-AX4M card provides four high–end analog inputs (both line and microphone level) with professional XLR connectors for the AuviTran Audio ToolBox platform.

Featuring four high performance microphone and line pre-amplification, high class AD converter chips and excellent circuit design, the AxC-AX4M card sets a new quality/price ratio standard for professional applications.

A linear 0.5 dB step digital attenuator/gain gives access to an input sensibility from -55 dBu to +24 dBu.

+48V phantom power activation per channel, preamp value setting, attenuation/gain setting and vu-meter can be monitored and controlled individually per channel via network for a remote management from virtually anywhere.

All individual gains and +48V phantom power activation remote controls are manageable by Yamaha HA remote protocol enabling direct control and monitoring from Yamaha console/mixer.

Up to two AxC-AX4M cards can be inserted in an AVBx3-ES100 for two kinds of application:

Live applications

  • Live concerts and recording
  • Live broadcast studios and OB Vans
  • Recording studios…

Fixed installations

  • Stadiums, concert halls
  • Theatres, bars, pubs discos
