Crown CTs4200A: 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.

Operating Features

• High power density. All two channel models and four channel model in a 2RU chassis, eight channel model in a 3RU chassis
• New Crown Switching Power Supply for lighter weight
• 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 4200A, and CTs 8200A
• 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· New "FIT" (Fault Isolation Topology) circuitry on 4- and 8-channel models isolates fault conditions without affecting neighboring channels
• Comprehensive array of indicators provide accurate diagnostics
• Two-channel models are fully PIP2-compatible. Multi-channel models accept new MC accessory modules
