CROWN CTs2000 เพาเวอร์แอมป์ เครื่องขยายเสียง Power Amplifier 1000 watt @ 8 ohms

PRODUCT OVERVIEW

Crown’s CTs Series amplifiers provide exceptional performance, flexibility and value for installed sound applications. CTs Series amplifiers feature independent selection of high and low impedance operation for a specific channel, plus power levels and features that were carefully chosen to match the requirements of fixed install design. Easy integration with HiQnet™ and CobraNet™ allows CTs amplifiers to deliver a comprehensive lineup of monitoring and control features along with digital audio transport for an award-winning digital audio solution.

PRODUCT DETAILS

The Crown CTs-2000 is a 2-Channel power amplifier housed in a 2-space rackmount frame, offering power levels and features meant to serve fixed installation sound applications. This amplifier is notable for a completely independent array of switches and indicators for each channel, including high and low impedance operation, input sensitivity, high pass filters, and an advanced level of well designed overload protection circuitry.

• High-power, 2-channel, 2U rackmount amplifier for installed sound applications
• Switching power supply lowers overall amplifier weight
• Direct 70V/100V/140V/200V constant-voltage or 2/4/8 Ohm low-impedance operation
• Independently selectable Input Sensitivity switching per channel
• Rear panel Programmable Input Processor(PIP2) connector accepts accessory expansion modules for specific custom installation requirements
• Thermal Level Control(TLC) circuitry protects amplifier from overheating; engages input compressor, dynamically reducing input gain when individual channels overheat
• Junction Temperature Simulation(JTS) quick-activation circuitry limits drive level of output devices to tolerable range if excess power is required; protects output transistors without shutting down channel
• Continuously variable fan cooling; venting with front-to-rear forced airflow
• Removable balanced terminal block input connectors with "Y" switch
• Switchable high pass filter per channel, eliminates step down transformer saturation in distributed systems
• Complete array of front panel function and warning indicator LED's for each channel
• Complete array of rear panel function and filter switches
• Power on indicator flashes when AC mains are under or over voltage
• Advanced protection circuitry covers shorted outputs, DC, mismatched loads, overheating, high frequency overloads, voltage fluctuation and internal faults.
