Back Panel Controls and Connectors
Reset Switch: Resets the circuit breaker that
protects the power supply. 220/230/240V units
have a fuse instead.
AC Power Inlet: Detachable IEC.
Auxiliary Power Input: 2-position terminal strip
for 24 VDC (±10%) backup power. Accepts up to
14 AWG terminal forks.
Amplifi er Outputs Connectors: One per channel,
4-position terminal strip with COM (Common), 4
ohms, 70V and 100V terminals. Accepts up to 14
AWG terminal forks. Non-touch cover included.
Output VCA Connector: 4-pin Phoenix-type
connector for two VCA control lines of +10 VDC
and ground. Compatible with Crown 1-VCAP and
4-VCAP modules.
Amp Confi g Switch: A DIP switch with two func-
tions:
1. Assigns an input as the priority input for each
output, thereby temporarily muting the remaining
inputs. Muting is activated by contact closure.
2. Global enable switch for phantom power. Does
not affect RCA inputs. Default position is off.
Priority Connector: 3-pin Phoenix-type connector
allows Input 1 or Input 5 (280MA only) to mute
other input signals by contact closure.
Input Routing Switch (280MA only): DIP switches
that assign each input signal to each output. Two
switches per input.
Line Out Connector: One 3-pin balanced Phoenix-
type connector per output channel. Post master,
pre-VCA. Level controlled by master volume
control.
The tone generator has been omitted. Call Crown Tech
Support if you have a tone generator question.
Input Connectors:
Mic/Line Connector: 3-pin Phoenix-type, bal-
anced, one per input channel.
Dual RCA Input Connector: For stereo music
signals, unbalanced, summed together, two con-
nectors per input channel.
Amp Input Connector: 3-pin Phoenix-type, high-
impedance balanced, one per amplifer channel.
Used to link an additional mixer to the mixer-
amplifi er. Can be used to connect an external
processor.
Mic/line Switch: Selects mic-level or line-level
signals. One switch for each balanced input.
Link In/Out Switch: Slide switch, one per channel.
With the Link Switch IN, any signal applied to the
Amp Input connector will be mixed with the input
signal(s). With the Link Switch OUT, only the
signal from the Amp Input Connector will appear
at the amplifi er output.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown mixer-amplifi er—
an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown mixer-
amplifi er is warranted to meet or exceed original specifi cations for the fi rst three years of ownership.
During this time, if your mixer-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 mixer-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.
