Digigram VX222e Mic PCI Express Sound Card

The Digigram VX222e Mic PCI Express Sound Card is the PCI Express version of the VX222HR-Mic linear sound card for demanding applications in broadcast, production, or voice-over recording. Exacting specs, outstanding quality, absolute reliability and total connectivity make this new generation the number one choice for pro audio manufacturers and software vendors.

Digigram VX222e Mic PCI Express Sound Card Features:
-24-bit/192kHz AD/DA converters
- +24 dBu maximum analog signal levels
-3-band parametric EQ and maximizer,
-LTC, and interboard synchronization inputs
-Native, low-latency HR driver package: WDM DirectSound, ASIO, Wave and driver for Digigram SDK
-DirectSound driver signed by Microsoft Windows Hardware Quality Labs
-One professional grade analog mic preamp with analog compressor limiter, mixed with the analog line inputs
-Hardware sample rate converter on the digital input
