Standard sound cards are PCI cards or motherboard integrated modules, and are used to play back digital audio signals (2, 4, 6 or 8 sound channels) and/or to digitize analog video signals.
Usually standard sound cards have 1 output for connecting loudspeakers or headphones (modifications exist with 2 and 3 outputs for multi-channel sound realization and some others) and 1 input for connection of microphones.
| Sound cards have one plug for 2 channels to connect microphones to. To connect 2 microphones, resolder the connector or use the mini jack 2xRCA adapter. |
Standard sound cards perform sound playback and audio signals digitization in parallel.
The audio signal sampling rate range depends on the audio card type. The Axxon PSIM™ software system sampling rate range, available to the installed card, is bounded by the 48 kHz maximum value.
