Digigram VXPocket 440
Digigram's VXpocket 440 offers the power to perform serious audio production on laptop computers by presenting excellent audio quality plus compatibility with the most popular applications under Windows, the Mac OS, and Linux.
The two VXpocket models provide 24-bit performance with PC applications using Microsoft's WAVE protocol and ASIO, Mac applications using Core Audio and ASIO, as well as Linux applications using the ALSA standard.
Both cards feature one stereo SPDIF input and output allowing digital record/playback and an LTC (SMPTE) time-code input. A breakout cable is provided with XLR connectors for the analog inputs/outputs, phono connectors for digital and LTC, and a stereo mini-jack for headphone monitoring.
The VXpocket 440 has four balanced mic/line analog inputs and four balanced analog outputs. The number of active stereo inputs and outputs available varies with the sampling frequency and bit rate selected. The user may optimize performance based on user preferences for number of input/output, audio file format, and computer CPU usage.
The VXpocket v2 has two balanced analog mono inputs at microphone or line level and two balanced analog outputs.
If the possibility of running sophisticated audio applications on your laptop has sparked your imagination, this range of cards can turn your concept into a reality.
