AB400 High Power Bi-Channel Amplifier Board (400W+400W)

Description: AB400 High Power Bi-Channel Amplifier Board (400W+400W) Product Description:16-tube 400W + 400W ultra-high-power professional amplifier boardAB400 dual-channel professional stage amplifier board circuit design is mature and stable, the use of dual differential inputs and increased signal processing at the input side, push the stage with a pair of 1930/5171 plus 5200/1943 to do the composite push, and then 16 tubes to do the power output level.Level, the output power up to 400W + 400W, huge power, strong low-frequency, rich in detail, the circuit adopts DC feedback design, good resolution, deep bass dive, good elasticity, high power under the work of stable, free playback.The board is designed with complete protection circuits, including switching delay protection to prevent a shock sound. Midpoint voltage protection, overcurrent protection, high temperature protection, and cooling fan interface. Selected all imported Toshiba TTA1943/TTC5200 audio pair tubes, carefully paired and assembled.Notes.1, the circuit board power supply need to use dual 50V-70V high-power transformers, and then add rectifier filter board to access the AB400 amplifier board, can not be directly connected to the transformer.It is recommended to use dual 50V or more toroidal ox transformers, too low a voltage will lead to circuit board. The working state is not normal, the sound distortion.2, the circuit board AC12V interface is to protect the circuit power supply, you need to connect the transformer's 12V output alone, can not be shared with other lines.3, AB400 quiescent current does not need to be set too large, otherwise the heat becomes large, easy. Burn the tube.4, AB400 installation and debugging requires professional knowledge of the circuit, if it is a lack of experience, please study and understand before you start.Product Dimensions.Product Specification.Model: AB400Output channel: 2.0 channelAmplifier: TTA1943*8, TTC5200*8Amplification: 25 timesFrequency Response Range: 20-20KHzMain voltage: DC dual 50V-110V, need to add their own rectifier boardOutput power: 400W+400W/4Ω,200W+200W/8ΩTotal harmonic distortion:0.01%Protection mechanism: overheating protection, overcurrent protection, midpoint voltage protection, power-on delay protection.Size: 220*84*100mmWeight: 1KG .
