INTRODUCTION
C-MARK TD series adopts PFC switching power and class D digital amplification circuit. This amplifier is characterized by fabulous tone, high efficiency, light weight, stable and reliable working performance, high cost-effective and with perfect protection function(short-circuit protection, over-current protection, over temperature protection, over-voltage protection, insufficient voltage protection, temperature limiter, input signal limiter)and nice character of electromagnetic compatibility. Range of voltage of power supply is AC90-264V 45~65Hz, which is suitable for universal power. The unit is applicable to various occasions like theatre, multi-function hall, large gymnasium, theme park, outdoor tour performance and stadium.
FEATURES
Indication Of Fault:
To show the amplifier is working normally, in case of over voltage protection, insufficient voltage protection, short circuit protection, overload protection, overheat protection, output DC protection,the yellow "Fault" LED in the front panel of the amplifier will be illuminated.
Short Circuit And Overload Protection:
When short circuit or overload happens, the function of short circuit protection will be activated to protect the amplifier from being damaged.
Output DC Protection:
If there is output DC signal in the output channel, instantaneous protection circuit will cut off power of all channels to ensure the safety of other supported products.
Over Voltage、insuffcient Voltage Protection:
If power supply of amplifier is higher or lower than required range of working voltage of the amplifier, the system will cut off the amplifier automatically to protect it.
Temperature Controlling Fan:
The working state of the fan can be automatically controlled based on internal temperature of the unit, when the internal temperature exceeds 45°C, the fan begins to rotate to lower internal temperature. When the temperature is lower than 30°C, the fan stops rotating to achieve optimal effect of transmitting heat, which will not bring about environmental noise.
Indication Of Temperature Power Limiter:
Indication of temperature power limiter mainly refers to heat protection function. The amplifier can automatically adjust internal temperature when working to keep the temperature among the limited range, so the key components of the system can work under the steady temperature. If surrounding temperature rises, power will be gradually reduced to the sustaining state, the yellow temperature power control LED in the front panel of the amplifier will be illuminated at the same time.
The function of the other kind of heat protection circuit refers to the fact that when power reduces, internal temperature can not be sustained below 75°C, the amplifier will stop working and the fault-indication yellow LED in the front panel will not be illuminated until temperature drops to safe level.
When internal temperature is below 65°C, the system will be recovered automatically.
Input Signal Limiter:
When the input signal exceeds 0dB, limiter circuit automatically starts to prevent clip distortion from occurring in output power so as to maintain full peak power.
Wider Range Of Voltage Of Power Supply:
Range of power supply is AC90-264V 45-65Hz, which is suitable for global power supply.
