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.

CTs 600

Clip Indicator: Red LED, one per channel,

illuminates 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 IQ Loop

data activity (if the ampliﬁ er is equipped with an

IQ-PIP2 module, and connected to an IQ Loop).

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: Balaced 3-pin terminal block

connectors, one per channel, on the standard

PIP

-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 IQ-PIP-USP2

and IQ-PIP-USP2/CN.

Protection Systems

Thermal Level Control (TLC): If an ampliﬁ er

channel starts to overheat, the TLC system 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.

The degree of compression is proportional to

the amount of overheating. This feature allows

the show to go on, rather than having the

ampliﬁ er shut down.

Junction Temperature Simulation (JTS): JTS

circuitry simulates the operation of the ampliﬁ -

er’s output transistors, and compares it against

the transistors known Safe Operation Area

(SOA). If JTS sees that more power is about

to be asked of the output devices than they are

capable of delivering under the present condi-

tions, JTS immediately limits the drive level

until it falls within the SOA. Limiting is propor-

tional and kept to an absolute minimum—only

what is required to prevent the possibility of

output transistor 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

ampliﬁ 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 sig-

nals.

Inrush 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 ampli-

ﬁ er for cooling.
