Part of the ALP-X professional sound-card range, the Digigram ALP442e is a multichannel, PCIe sound card designed for professional PC-based audio systems running under Windows and Linux environments. ALP442e is a reliable and stable match for applications such as broadcast (24/7/365), audio production, and outstanding audio-quality measurements.
The low-profile ALP442e is equipped with 4 balanced analog line inputs plus one AES3 input, 4 balanced analog outputs plus two AES3 outputs, 8 GPIs, and 8 GPOs. The zero-latency, onboard FPGA 16x16 mixer (4 analog, 3 AES3, 8 software play/record) enables you to route and mix audio channels from physical and software input devices to physical and software output devices. The low-latency drivers are multicard (up to 8 ALP cards) and multiclient. Breakout cables for analog I/Os and digital I/Os are available separately.
