PRODUCT DESCRIPTION
The HR-2000 PC board
works as a precision two channels A/D D/A audio front-end for your IBM
or compatible PC. The instrument grade input and output analog circuitry
and its wide range of output attenuation and input gain allows an easy
interface to the outer world; the two input channels can be controlled
separately or as a single balanced one; switchable phantom supply lets
you directly connect an Audiomatica MIC-01 or MIC-02 microphone to the
HR-2000 input. Dual DMA handling permits both generation and acquisition
to be performed in background giving maximum flexibility and ease of operation.
AVAILABLE SOFTWARE
CLIO 4.5 system software for MS-DOS or CLIOwin system software for Windows 95, 98, or Me (Windows 2000 or XP are not supported by the HR2000 ISA card; refer to the PB4281 PCI card).
