Amplifier Groundaudio DM-12K
Main Features
Amplifier Module
DM Series Professional Power Amplifier Using Class-AB Analog Output, Combined With Dynamic Power Supply PWM Modulation Technology, High Efficiency Of 90% Is Close To The Topology Class D, While Retaining High-fidelity Output Pure Analog Signal Without Compromise Between Efficiency And Quality
Power Modules Commonly Used Copper Pin DIP Components, Neat And Clean Layout, Scientific And Rational
MOS Transistor With High Conductivity Ceramic Substrate, Directly Fastened To The Heat-dissipate Aluminum Device- Application Of These Design Concepts For High-power Modules Play A Crucial Role In Terms Of Reliability
DSP
The Built-in DSP Audio Processing Module Is A DSP Chip Processing Module Based On ADI Professional Audio Processing- Which Provides Rich Audio Effects For Professional Amplifiers
- In Addition To The Conventional Audio Effect Algorithm, 5 Groups Of Preset Program Parameters Can Be Called Directly And Quickly, And The Effect Parameters Can Be Driver-freely Connected With Computer, They're Customized Or Stored By The Users
- DSP Module Has Self-contained Signal Indication And Clipping Monitoring, Each Channel Is Independent
SMPS Module
High Peak Lossless Absorption Flyback Switching Power Supply Topology Makes DM Series More Suitable For Large Dynamic Amplification Mode- Up To 10 Pieces Of Large-capacity Capacitors Of Maximum 16,000W Output Power Watts Can Ensure That Two Channels Simultaneously Have Strong Output Power As Well As Release Output Power Immediately
- It Also Ensures The Full Power Output And Distortion-free Sound Even In A Significant Voltage Pulsation
Using A New Layout Of Cooling, And Further Optimize The Cooling Defects Of Traditional High-power Switching Power Supply- Greatly Improving The Product Temperature Rise And Durability, And Ultimately Improve Product Stability And Reliability
System Protection
It Has Multiple Protection Features Such As Output Short Circuit Protection, Overload Protection, DC Protection, High-frequency Whistle Protection, Over-temperature Protection, Output Voltage Automatic Limiter, On / Off Progressive Volume Etc- Well Protect Your System Devices
Sound Characteristic
Very High Dynamic Range And A Very Broad Frequency Response (20Hz-20KHz +/- 0- 5dB
- )
- Low Frequency Is Clear, Low Dive Space, Especially For Large-diameter Speaker, Can Precisely Control, Super Shocking Bass
- Middle Frequency Warm And Natural Voice Full Of Charm
- High Frequency Extension Is Good, Analytical Ability, Clear And Translucent
Quality Assurance
Output Stage Module - Adopting The Most Advanced Modulation Power Supply Technology And Enhanced Drive Circuit Makes The Output Stage Module More Efficient And Ensures A Lower Temperature Rise- All Devices Use Copper Pin DIP Componets
- Power Tubes Are Installed Directly In The Aluminum Radiator Without Insulation Medium, Through Reducing Thermal Resistance To Increase Transient Allowance, Ultimately Reduce The Risk Of Burning Power Tubes
SMPS Module - Using Enhanced Power Supply, Neat And Clean Layout, Scientific And Rational- SMPS Module Has Independent And Completed Cooling Duct, Which Are Very Important For Large Power SMPS Amplifiers
- SMPS Module Adds A Set Of Separate Metal Shields To Achieve A More Professional Partition Layout Between Modules
