CDi Series
CDi SERIES
The CDi Series of Crown®amplifiers are
professional tools designed and built for
installed sound applications. The series
includes three models which are identical
except for output power: CDi 1000, CDi 2000,
and CDi 4000. All are rugged and lightweight,
and offer unmatched value in their class.
CDi-Series amplifiers feature an intuitive front-
panel LCD screen to guide installers through
their configurations. CDi amplifiers also offer
onboard DSP for loudspeaker signal process-
ing. Other features include a switch-mode
universal power supply, useful function indica-
tors, proportional-speed fan-assisted cooling,
removable Phoenix-style inputs, barrier strip
outputs for low-Z or 70V/100V/140V loads,
short-circuit protection and more.
Your investment in a CDi-Series amplifier is
backed by Crown’s Three-Year, No-Fault, Fully
Transferable Warranty.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifier is warranted to meet or exceed original specifications for the first three years of
ownership. During this time, if your amplifier fails, or does not perform to original specifications,
it will be repaired or replaced at our expense. About the only things not covered by this warranty
are those losses normally covered by insurance and those caused by intentional abuse. And the
coverage is transferable, should you sell your amplifier.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside
of the USA, please contact your authorized Crown distributor for warranty information or call
574-294-8200.

nel, illuminates when a very low-level signal is
present at input.
–10 Indicator: Green LED flashes when output
signal exceeds –10 dB below clip.
–20 Indicator: Green LED flashes when output
signal level exceeds –20 dB below clip.
Ready Indicator: Green LED, one per chan-
nel, illuminates when the amplifier is ready to
produce audio.
Clip Indicator: Red LED, one per channel, turns
on at the threshold of audible distortion.
Temp Indicator: Red LED, one per channel,
illuminates under excessive temperature
conditions.
Power Indicator: Blue LED illuminates when
the amplifier has been turned on and has
power.
Rear Panel Controls and Connectors
AC Line Connector: NEMA 5-15P (15A).
Input Connector: Two 3-pin removable
Phoenix-type connectors each accept a
balanced line-level input signal.
Output Connectors: 4-position barrier strip
with connectors for dual louspeakers or bridge-
mono loudspeaker. Dual connectors work with
2-8 ohm or 70V/100V loads. Bridge-mono con-
nectors work with 4-8 ohm or 140V loads.
HiQnet USB Connector: Type B, connects to a
USB port on a PC.
Protection
CDi-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.
