Protection
DSi-Series amplifiers are protected against
shorted, open or mismatched loads;
overloaded power supplies; excessive
temperature; chain destruction phenomena;
excessive output current, and input overload
damage. They also protect loudspeakers
from input/output DC, large or dangerous DC
offsets and turn-on/turn-off transients

Regulatory Certifications
Note: All measurements apply to all models of CDi
Series amplifiers in stereo mode with 8-ohm loads and
an input sensitivity of 26 dB gain, 1 kHz at rated power
unless other otherwise specified. Specifications for
units supplied outside the U.S.A. may vary slightly at
different AC voltages and frequencies.
