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).
