Overview
Digigram ALP442e-MIC, Multichannel PCIe Sound Card with MIc/Line Inputs
LP442e-MIC is the versatile PCIe sound card for professional PC-based audio systems running under Windows and Linux environments that require up to 8 microphone inputs. This card is ready for any
challenge and guarantees unrivaled quality when audio and voice recording applications are critical – audio production, equipment monitoring and recording markets. Low profile form factor ALP442e-MIC is
equipped with switchable 48V phantom power and high-end preamplifiers. It also features 4 balanced analog mic/line inputs, 2 stereo AES3 inputs, 4 balanced analog outputs, 2 AES3 outputs, and 8
GPIOs.The on-board zero latency mixer features 16 I/O channels (4 analog, 4 AES3, 8 software play/record). Each of the 16 output channels has its own mix from the 16 inputs
- Outstanding audio quality and performance
- Made for regular application or custom design with help of Digigram control API
- Rock-solid, life-long, hiccup free reliability
- Fits in any type of PC / workstation / server with a PCIe slot
- Drivers evolve with Windows and Linux updates
- Onboard high quality mic preamps
Breakout Cable Not Included and is Required. See Digigram DIG-SC2422A0301
