AMUR-PCI-A-18

Многоканальный регистратор «AMUR-PCI-A-18»

Purpose:

Multichannel recorder «AMUR-PCI-A-18" - a hardware and software system for PC-based, designed for high-quality recording, storage and playback of analog audio information. The sources of information can be telephone or any other communication channels or analog sensors. Complex is able to record up to 18 channels simultaneously. The recorder can be delivered independently or be part of (as a subsystem) multichannel automatic recording devices «AMUR».

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.
Type of trunk:
PCI
Record channels have the universal galvanic isolation between that makes it possible to connect any sources of signals with program presetting.
