AC Line Voltage and Frequency Confi gurations
Available
(±10%):
120VAC/60 Hz and
240VAC/50 Hz.
Controls
Level:
Two or four front-panel, gray rotary
level controls, one for each channel.
Power On:
Front-panel switch; on when in the
right-hand position.

Two or four green LEDs, one for each
channel, illuminates when the channel’s input
signal level is above –40 dBu.
Clip:
Two or four front-panel red LEDs, one for
each channel, illuminates when the channel’s
output signal is being overdriven.
Power:
Yellow front-panel LED indicates
amplifi er has been turned on and AC power
is available.

: Red front-panel LED indicates the
presence of AC power at the power cord, even
if the amplifi er is not turned on.

Input/Output
Input Connectors:
XLR-1/4" combo connectors: One per channel,
3-pin female XLR connector and TRS 1/4"
phone jack accept balanced or unbalanced
signals.
3-pin Phoenix-style connectors (2-channel
models only): One per channel, accepts bal-
anced or unbalanced signals.
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.
