CROWN CTs Series
Speaker impedance will change with frequency , CTs have a constant output power at 4 ohms - 8 ohm load almost unanimously to make the system more flat frequency response , the volume does not change with frequency when large small , especially for the music sound
Features:
• patented grounded bridge design provides high output voltage capability , so as to enhance its power output.
• novel switching power supplies, and lighter weight.
• CTs 1800, CTs2000, CTs2800, CTs3000, CTs4200, CTs8200 provide 100V constant voltage output.
• Crown CTs Series amplifiers efficacy through different channels to configure different options that can support HiQnet network protocol and is compatible Harman Professional System Architect software and Crown IQ system , which used CROWN TCP / IP digital audio transmission and monitoring technology won the 2003 outstanding Technical Achievement award .
• Unique leading digital power amplifier output circuit I .
• Optional achieve studio -level signal processing.
• 4 and 8-channel amplifier module offers excellent power output of independent multi-zone PA system .
• novel FIT technology ( Top network fault isolation technique ) the protection circuit 4 and 8-channel modules can isolate faults , does not affect the normal operation of the adjacent channels .
• The new thin design , the 2U of rack space and maintain a four -channel modules 2 ; 8 -channel modules only 3U of rack space.
• The constant voltage output , each module can be inserted into a high- pass filter to reduce the frequency signal sorrow ;
• Comprehensive front panel indicators show the channel display module status , channel activation , IQ status, signal strength , thermal protection , clip and fault LED flashes.
• With signal short circuit, open circuit , DC output , overload , overheating , high-frequency self-excited protection circuit.
Rated output power
Guaranteed minimum output rate ( all channels driven , 1.4V input sensitivity , 120V, 60H bamboo AC )
保证的最小输出率（全部信道驱动，1.4V输入灵敏度，120V，60H竹交流电源）
