Indicators

(all located on front panel)
Signal: A green LED for each channel which
fl ashes when a very low-level signal (>–40
dBm) is present at input. May be used for
troubleshooting cable runs.
Clip: A red LED for each channel which turns
on when distortion becomes audible in the
amplifi er output.
Fault: Normally off, this red indicator will blink
under fi ve different conditions:
1. When the amplifi er is fi rst powered up, until the
unit is ready for operation.
2. If the heatsinks reach a temperature above nor-
mal working limits.
3. If the transformer thermal protection circuit is
activated.
4. If amplifi er output wires develop a short-circuit.
5. Should the amplifi er output stage become non-
operational.
This circuit may be monitored remotely by
plugging a simple switching circuit using an
LED or other signaling device into the back-
panel RJ-11 (Fault) jack. Under some condi-
tions, the output of the amplifi er will be muted.
Power: A green LED that turns on when the
amplifi er has been turned on and has power.

Input/Output

Input Connector (standard module): One Neu-
trik ® Combo connector for each channel which
features a balanced 1/4-inch (6.35-mm) phone
jack and a 3-pin female XLR connector, in
parallel with a barrier strip termination.
Input Stage: Input is electronically balanced
and employs precision 1% resistors.
Input Impedance (nominal): 20 k ohms, bal-
anced;10 k ohms, unbalanced.
Crown's Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fi er—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifi er is warranted to meet or exceed original specifi cations for the fi rst three years of
ownership. During this time, if your amplifi er fails, or does not perform to original specifi cations,
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 amplifi er.
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.

Protection
CE-Series amplifi ers are protected against
shorted, open or mismatched loads; overloaded
power supplies; excessive temperature; chain
destruction phenomena; input overload dam-
age; and high-frequency blowups. They also
protect loudspeakers from input/output DC,
large or dangerous DC offsets and turn-on/
turn-off transients.
