600 watts @ 8 ohms mono

Building on the foundation of the Com-Tech Series, Crown's CTs Series offers new flexibility and value for installed sound applications. The Com-Tech Series were the first to offer independent selection of high- and low-impedance operation for a specific channel, and CTs Series amplifiers continue that tradition, with power levels and features carefully chosen to perfectly integrate into fixed install design requirements. For added flexibility, 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 the IQ System. Two-channel models accept PIP2™ modules, and also feature selectable high-pass filters and input sensitivity for each channel. In a profession where unplanned service calls quickly wipe out profits, the CTs Series amplifiers are designed to be the most reliable amplifiers 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 amplifier in standby mode via the IQ 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: amplifi er output is 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 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 IQ Loop data activity (if the amplifier is equipped with an IQ-PIP2 module, and connected to an IQ Loop).
  • 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.

  • 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.

• 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 amplifier channel starts to overheat, the TLC system 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 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 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.
  • 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 amplifier for cooling.
