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 ampliﬁer in standby mode via the control system.

Signal Indicators: Three green LEDs per channel indicate the ampliﬁer’s input and output signal levels.

Signal: input signal is above –40 dBu. –20 dB: ampliﬁer output is 20 dB below clipping. –10 dB: ampliﬁer output is 10 dB below clipping.

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 ampliﬁer 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, ﬂashes when the ampliﬁer output channel has stopped operating.

Data Indicator: Yellow LED indicates control data activity (if the ampliﬁer is equipped with an IQ-PIP2 module, and connected to a control system).

Power Indicator: Blue LED indicates ampliﬁer has been turned on and AC power is available. The LED will ﬂash when the AC line voltage is 15% above or 25% below the nominal rated value.

Cooling Vents: Front-to-rear forced airﬂow. 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 inﬁnity (–70 dB) to 0 dB gain.

Mode Switch: Two-position switch is used to select the ampliﬁer’s mode of operation: Dual or Bridge-Mono.

Highpass Filter: One 3-position switch per channel selects between OFF, 35Hz and 70Hz 3rd-order ﬁlters.

“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 ampliﬁer.

Ventilation Grille: Front-to-rear forced airﬂow.

Options

PIP2 modules, including the PIP-Lite, PIP-USP3, and PIP-USP3/CN.

Protection Systems

Thermal Level Control (TLC): If an ampliﬁer

channel starts to overheat, the TLC circuit will engage the input compressor. By compressing the input, the ampliﬁer 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 ampliﬁer will light the Fault LED if the ampliﬁer 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 ampliﬁer, the ampliﬁer’s power supply turns off and the blue Power LED ﬂashes. The ampliﬁer will turn back on when the AC line voltage returns to safe operating levels.

Circuit Breaker: This breaker protects the ampliﬁer from excessive AC current draw.

DC Output Servo: The output servo circuit protects 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 ampliﬁer’s current draw during power-on.

Variable-speed Fan: Two continuously variable speed fans direct the airﬂow through the ampliﬁer for cooling.

Front Panel Controls and Indicators

Bridge Mode Indicator: Yellow LED, one per channel pair, illuminates when the channel pair’s Mode Switch is set to the “Bridge” position. If Mode switch is changed while ampliﬁer is powered up, Bridge LED will ﬂash, indicating that the ampliﬁer must be powered off and on to reset the Mode.

Ready Indicator: Green LED, one per channel, illuminates when the channel is initialized and ready to produce audio output.

rown’s CTs Multi-Channel Series offers wide flexibility for a wide range of installed sound applica-

tions. CTs Multi-Channel Series amplifiers offer independent selection of high- and low-impedance

operation for each channel pair, making these amps ideal for multi-zone installations.

Signal Indicator: Green LED, one per channel, illuminates to indicate the presence of analog input signals above –40 dBu.

Clip Indicator: Red LED, one per channel, illuminates when the THD of the channel’s output signal rises to a level typically considered as the onset of audible clipping. The Clip Indicator also will illuminate during Thermal Level Control (TLC) or input overload.

Thermal Indicator: Red LED, one per channel, ﬂashes when a state of thermal stress or overload has caused the channel to shut down. If the power supply goes into thermal overload, all channel LEDs will ﬂash.

Fault Indicator: Red LED, one per channel, ﬂashes when a fault condition has occurred in the channel.

Ventilation Grille: Front-to-rear forced airﬂow. Data Indicator: Yellow LED indicates IQ Loop data

activity (if the ampliﬁer is equipped with an IQ-MC module, and connected to an IQ Loop).

Power Indicator: Blue LED indicates ampliﬁer has been turned on and AC power is available. Indicator also ﬂashes if the ampliﬁer shuts off due to an under-/over-voltage condition on the AC mains.

Power Switch: Ampliﬁer is on when the switch is in the IN position.

Back Panel Controls and Connectors

AC Power Cord Connector: IEC inlet, type 320; 100/120VAC units: 15A; 220/230/240VAC units: 10A. Voltage is indicated above IEC inlet.

Output Connectors: One four-pole terminal strip for every two channels with touch-proof cover. Accepts up to 10 AWG terminal forks.

Accessory Panel: CTs 4200 accepts an optional VCA-MC4A module. CTs 8200 accepts an optional VCA-MC8 module.

Control Modules: VCA-MC4A: VCA module for CTs

4200A. VCA-MC8: VCA module for CTs 8200.

Wall-mount level control panels for use with VCA module: 1-VCAP: Single-gang panel with 1 VCA

channel volume control. 4-VCAP: Two-gang panel with 4 VCA channel volume controls.

T-170V: This is an autoformer that allows 100V output from the ampliﬁer, and allows other ampliﬁers without direct constant voltage output to be easily integrated into distributed systems.

TP-170V: This is a rack-mountable panel with four autoformers as described above.

Protection Systems

Thermal Level Control (TLC): If an ampliﬁer channel starts to overheat, the TLC circuit will engage that channel’s input compressor. By compressing the input, the ampliﬁer 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. If the channel becomes too hot for safe operation even after full TLC limiting, the channel will shut off, and the Thermal Indicator for that channel will ﬂash brightly to alert the user that a state of thermal stress or overload has cause the channel to shut down.

FIT (Fault Isolation Topology): Isolates faults within affected channels.

Fault: If an ampliﬁer channel requires service, the corresponding Fault indicator will illuminate to alert the user of this condition. If this occurs, return the ampliﬁer to the Crown factory or to an authorized Crown service center.

High-Pass Filter: A ﬁxed 35-Hz (70-Hz in CTs 4200) high-pass ﬁlter per channel pair is automatically inserted when the mode switch is set to either of the constant-voltage settings. The high-pass ﬁlter corner frequency in the CTs 8200 can be set to 70 Hz, or bypassed, with a service option.

AC Under-/Over-Voltage Protection: If the AC line voltage varies out of an acceptable range, the ampliﬁer’s power supply turns off and the blue Power LED ﬂashes. The ampliﬁer will turn back on when the AC line voltage returns to safe operating levels.

Models
