AMUR-PCI-A-18
Purpose:
Structure
The recorder can be delivered independently or to be a part (as a subsystem) of the multichannel automatic audio recorder «AMUR». The structure of the registrar includes PCI printed-circuit board with the software (CD-ROM). On request of the customer we choose the personal computer (PC) on which the few/multichannel recorder is established. The Data recording is made on a personal computer hard disk. There is a low profile variant of a PCI printed-circuit board with number of channels up to 8. It is AMUR-PCI-A-08-LP (for installation into 2U and Slim cases)
Specifications:
Quantity of channels on the printed-circuit board. | 2-18 channels per one printed-circuit-board (The quantity of printed-circuit-boards in one system block is limited by the quantity of PCI. |
