CROWN CTs3000 เพาเวอร์แอมป์ เครื่องขยายเสียง Power Amplifier 1200 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-3000 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.
