Evaluation Amplifier
GENERAL DESCRIPTION
The EB-2100x is an evaluation amplifier that
showcases Apogee’s all-digital, high efficiency Direct
Digital Amplification (DDX
) technology. The board
features a DDX-2000 Controller and DDX-2100
Power Device which provide full digital audio
preamplifier functions and power amplification. The
board includes both coaxial and optical S/PDIF
interfaces, digital volume and balance controls and
local power regulation to operate from a single supply
voltage.
The EB-2100x is available in both a stereo 50W (EB-
2100S) and a mono 100W version (EB-2100M).
