Front Panel Controls and Indicators
Bridge Mode Indicator: Yellow LED illuminates 
when the rear-panel Mode Switch is set to the 
“Bridge” position.
Ready Indicator: Green LED, one per channel, 
illuminates when the channel is initialized and 
ready to produce audio output. Indicator is off 
when PIP puts the amplifi er in standby mode via 
the control system.
Signal Indicators: Three green LEDs per channel 
indicate the amplifi er’s input and output signal 
levels.
Signal: input signal is above –40 dBu.
–20 dB: amplifi er output is 20 dB below clipping.
–10 dB: amplifi er output is 10 dB below clipping.
Clip Indicator: Red LED, one per channel, illumi-
nates when the channel’s output signal reaches the 
onset of audible clipping. The Clip Indicator also 
will illuminate during Thermal Level Control (TLC) 
limiting or when the input compressor/limiter is 
protecting the amplifi er from input overload.
Thermal Indicator: Red LED, one per channel, 
illuminates when the channel has shut down, or 
is very near shutting down, due to thermal stress 
or overload.
Fault Indicator: Red LED, one per channel, fl ashes 
when the amplifi er output channel has stopped 
operating. 
Data Indicator: Yellow LED indicates control data 
activity (if the amplifi er is equipped with an IQ-
PIP2 module, and connected to a control system).
Power Indicator: Blue LED indicates amplifi er has 
been turned on and AC power is available. The 
LED will fl ash when the AC line voltage is 15% 
above or 25% below the nominal rated value.
Cooling Vents: Front-to-rear forced airfl ow.
Power Switch: Push-on / push-off switch.
Back Panel Controls and Connectors
Power Cord Connector: Standard 15 amp IEC 
inlet. Voltage is indicated above IEC inlet.
Reset Switch: Resets the circuit breaker that 
protects the power supply.
Speaker Connectors: One four-pole touch-proof 
terminal strip. Accepts up to 10 AWG terminal 
forks. 
Input Connectors: Balanced 2-pin terminal block 
connector, one per channel, on the standard PIP2-
BBY module. 
Channel Level Control: One 21-position detented 
rotary attenuator per channel, ranging from minus 
infi nity (–70 dB) to 0 dB gain.
Mode Switch: Two-position switch is used to 
select the amplifi er’s mode of operation: Dual or 
Bridge-Mono.
Highpass Filter: One 3-position switch per 
channel selects between OFF, 35Hz and 70Hz 
3rd-order fi lters.
“Y” Input Switch: When set to ON, this switch 
parallels the input signals of the two channels for 
use when the input signal is mono. Also can be 
used to daisy-chain the signal to another amplifi er.
Ventilation Grille: Front-to-rear forced airfl ow.
Options
PIP2 modules, including the PIP-Lite, PIP-USP3, 
and PIP-USP3/CN.
Protection Systems
Thermal Level Control (TLC): If an amplifi er chan-
nel starts to overheat, the TLC circuit will engage 
the input compressor. By compressing the input, 
the amplifi er will not generate as much heat and 
will have a chance to cool down. 
Junction Temperature Simulation (JTS): In the 
CTs 600/1200, if excess power is demanded, JTS 
circuitry limits the drive level of the output devices 
to a safe range, preventing damage.
Fault: The amplifi er will light the Fault LED if the 
amplifi er output stage stops operating.
AC Under-/Over-Voltage Protection: If the AC line 
voltage drops below 25% or rises above 15% of 
the nominal operating voltage of the amplifi er, the 
amplifi er’s power supply turns off and the blue 
Power LED fl ashes. The amplifi er will turn back on 
when the AC line voltage returns to safe operating 
levels.
Circuit Breaker: This breaker protects the ampli-
fi er from excessive AC current draw.
DC Output Servo: The output servo circuit pro-
tects your drivers by eliminating DC offset, even in 
the presence of very large asymmetrical signals.
In-rush Limiting: A soft-start circuit in the power 
supply minimizes the amplifi er’s current draw 
during power-on.
Variable-speed Fan: Two continuously variable 
speed fans direct the airfl ow through the amplifi er 
for cooling.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown amplifi 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.
