POGEE’S

A

Analog Converter that provides a professional refer­ence standard for uncolored reference monitoring of digi­tal audio sources. Applications include open reel and video
based recorders for CD mastering, DAT Recorders, Hard
Disk Recorders, Digital Audio Workstations, multi-track
applications, and CD players. The
Bit resolution with unequaled sonic performance and ver­satility. 12v operation makes it ideal for portable use.

Digital Inputs

Standard interfaces include AES/EBU, SPDIF, Optical,

Sony SDIF and SDIF-II.

Front end digital processing is provided by a high speed
custom-configured gate array which extracts the maximum
performance from the D/A converters.

Converters

8x oversampled digital data drives two 20-bit Digital to
Analog converters.

These converters eliminate the usual large transitions
around zero, thus providing excellent low level performance
in addition to the inherent high level performance.

Special Filters

Award-winning Apogee filter technology is incorporated
in this unit to do away with the troublesome high frequency
images found in most of today’s consumer and professional
D/A converters.

Analog Outputs

An internal gold pin matrix provides various analog output
formats at gold male XLR output connectors, bypassing the
pitfalls of automatic balanced/unbalanced circuits.

Low Jitter Clock

Like its companion the
tures Apogee’s
to external sync sources and regenerates the clock, providing
an electronic flywheel effect that greatly reduces short term
timing irregularities, or “jitter.”
