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.

Specialize control program in OS  WINDOWS VISTA/XP/SEVEN/2000,WINDOWS SERVER 2003/2008

Input circuit, symmetrical galvanically isolated universal inputs

Connecting to the control channels 

 

 parallel
DC input resistance not less than 1 МOhм
Operation threshold of parallel protection 270V ± 30V
Full level of the input signals 100-7000 мV (is changed with the help of the amplification coefficient of the input amplifier program )
There is hardware-controlled signal shaper “automatic number identification” (all the time parameters are program-controlled)  
There is measurements of a linear voltage level from 3 V up to 127 V at 0,5 V intervals, with the operation thresholds that are set up by the program.
