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. Features High power density. All two channel models and four channel model in a 2RU chassis, eight channel model in a 3RU chassis Selectable "Constant-Voltage" or low-impedance (4/8 ohm) operation per channel on 2-channel models, and per channel-pair on 4-and 8-channel models 100V direct outputs on CTs 2000, CTs 3000, CTs 4200, and CTs 8200 Legendary Crown class-I (BCA) and AB+B output topologies offer the best in amplifier reliability 4- and 8-channel models offer perfect independent power solutions for multi-zoned systems· "FIT" (Fault Isolation Topology) circuitry on 4- and 8-channel models isolates fault conditions without affecting neighboring channels Two-channel models are fully PIP2-compatible. Multi-channel models accept MC accessory modules. 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 Comprehensive array of indicators including Power and Data, along with Bridge, Ready, Signal, Clip, Thermal and Fault for each channel, provide accurate diagnostics Blue Power Indicator flashes if the amplifier shuts off due to an under/over voltage condition on the AC mains New Crown Switching Power Supply for reduced weight High power-density, with four channels (CTs 4200) or eight channels (CTs 8200) in a 3U chassis Selectable constant-voltage (70V/100V) or lowimpedance (4/8 ohm) operation for each channel pair (channel pair must be operated in Bridge mode for 100V output) FIT (Fault Isolation Topology) circuitry isolates faults within affected channels TLC protection circuitry protects the amplifi er from excessive heat by subtly and dynamically reducing the gain only when necessary to reduce heat levels Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, under-/over-voltage, high-frequency overloads and internal faults Continuously-variable fans optimize cooling effi ciency 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 Proven Crown AB+B Multi-Mode® output topology 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 installationHigh power-density, with four channels (CTs 4200) or eight channels (CTs 8200) in a 3U chassis Selectable constant-voltage (70V/100V) or lowimpedance (4/8 ohm) operation for each channel pair (channel pair must be operated in Bridge mode for 100V output) Accepts VCA-MC accessory module that allows remote VCA volume control lus monitoring of shorted outputs, open circuits, DC, mismatched loads, general overheating, under-/over-voltage, high-frequency overloads and internal faults 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 Specifications Minimum Guaranteed Power: See power charts below.
