Product introduction:
- Circuit is the use of precision two - stage AB type.
- Power on delay "soft start" function, closed loop and control peak limiter,soft start,overheating protection,short circuit protection; Short circuit /over current, over voltage, over temperature,limiting perfect protection circuit.
- In terms of power supply, a-grade iron core and anoxic copper enameled wire are adopted to make the power more sufficient and the working temperature lower.
- The filter capacitor of power supply adopts special capacitors for audio frequency, with less distortion,lower internal resistance and faster and stronger charging and discharging current.
- The front panel is equipped with power indicator light, protection light,signal light and clipping light to display the current working state of the equipment.
- Adopting Hydrodynamic design, reasonable natural air cooling and forced air cooling, ultra-quiet operation, can withstand relatively harsh environment.
Product parameters:
- Frequency Response：（±1dB,1W/8Ω） 20Hz/20kHz
- THD+H:（Standard measuring condition，1W/8Ω/1kHz）≤0.1%
- Damping coefficient： ≥200
- SNR： -100dB
- Signal input interface: XLR is combined with (6.35), lotus input interface.
- Input sensitivity（Rated power 8Ω）：0.775V/1V/1.4V
- Input common mode inhibition：（1kHz）＞60dB
- Degree of separation：（Full power at 8gb / 1khz） ≥100db（1kHz）
- Input impedance (balance/unbalance)： 20kΩ/10kΩ
Product advantage：
Powerful digital audio The processor functions：Built-in balanced/divider/delay/pressure limits,and other functions.
Multiple import filter capacitance：Qualified capacitancepulse rectified DC to deal effectively,reducing AC interference, the sound will be cleaner.
