| Crown CTs1200 LITE CTs 1200 Amplifier With Installed PIP-USP3 Module Building on the foundation of the Crown« Com-Tech« Series, the CTs Series offers new fl exibility and value for installed sound applications. The Com-Tech Series were the fi rst to offer independent selection of highand low-impedance operation for a specifi c channel, and CTs Series amplifi ers continue that tradition, with power levels and features carefully chosen to perfectly integrate into fi xed install design requirements. For added fl exibility, the CTs Series includes both dual-channel and multi-channel models. All models in the CTs Series feature Crown's new Switching Power Supply for lighter weight, and all models are also compatible with Harman Pro System Architect as well as the IQ System«. Two-channel models accept PIP2? modules, and also feature selectable high-pass fi lters and input sensitivity for each channel. In a profession where unplanned service calls quickly wipe out profi ts, the CTs Series ampli- fi ers are designed to be the most reliable ampli- fi ers you can install.

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, 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, flashes when the amplifier 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 touchproof terminal strip. Accepts up to 10 AWG terminal forks. Input Connectors: Balaced 3-pin terminal block connectors, 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 IQ-PIP-Lite, IQ-PIP-USP3, and IQ-PIP-USP3/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. 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 amplifi er 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. Inrush 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 airfl ow through the ampli- fier for cooling. Features Switching Power Supply for reduced weight High power-density, with all two-channel models in a 2U chassis Direct constant-voltage (70V/100V/140V/200V) or low-impedance (2/4/8 ohm) operation Input sensitivity independently selectable for each channel TLC protection circuitry protects the amplifi er from long-term excessive heat by subtly and dynamically reducing the gain only when necessary PIP2 (Programmable Input Processor) connector accepts accessory modules that tailor the amplifier to suit specific applications Removable terminal block input connectors, with "Y" Input Switch in the standard PIP2-BBY module Switchable high-pass filter for each channel provides low-frequency roll off to eliminate step down transformer saturation when used in distributed systems Comprehensive array of indicators including Power, Data and Bridge, along with Ready, Signal, Clip, Thermal and Fault for each channel, provide accurate diagnostics Blue Power Indicator flashes if the AC mains is under/ over voltage Advanced protection circuitry guards against: shorted outputs, DC, mismatched loads, general overheating, under/over voltage, high-frequency overloads and internal faults JTS circuitry (CTs 600/1200) quickly protects output transistors from unsafe operating conditions without shutting the channel down Legendary Crown AB+B (Multi-Mode«) output topology in the CTs 600/1200 and Class I (BCA«) output topology in the CTs 2000/3000 offer the best in ampli- fier reliability Continuously variable fans optimize cooling efficiency Three Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications Crown's advance-replacement Profit Protection Plan provides quick, no-questions-asked replacement of covered amps should they fail at any time up to 6 months following date of installation |
