KSA100MKII 150W+150W Class A Power Amplifier Board Hifi Power Amp Board top

Description: Description KSA100MKII 150W+150W Class A Power Amplifier Board Hifi Power Amp Board for Domestic Use Advantages: - Class A amplifier board - High power - Warm tone - Solid sound - Excellent low frequency sound Features: - Excellent circuit structure refers to the circuit for KERLL in the United States; it is used with premium components to ensure better sound. Axial capacitors for Siemens as feedback capacitors and CBB capacitor for Sprague are used; all small capacitors are imported audiophile capacitors - Military resistors are used; Using original BI gray adjustable potentiometer and ERO audiophile input coupling capacitor - Bipolar transistor MJ15034/MJ15035 for ON Semiconductor; Bipolar transistor MJ15024/MJ15025 for ON Semiconductor; the tubes of the entire board are precisely matched to the same polarity - The first-stage decoupling capacitor. The output and power terminals are all high-current terminals. CNC heat-conducting aluminum bridge heat sink; it is recommended that the heat sink on one side should not be less than 3.5KG - On-board speaker protection circuit with over-current and overheating protection, and without noise when it turns on/off - 30A sealed relay enables larger current. Sealed design ensures that it does not get wet, the contacts are not easily oxidized, its service life is longer, and the performance is more stable Specifications: - Item name: Class A power amplifier board - Frequency Response: 20-20KHz - Signal-to-noise ratio: 100dB - Output impedance: 4-8Ω - Power supply range: dual DC 32-60V plus AC 12-18V; recommended dual DC 45V plus AC 12V - Power supply scheme: It is recommended to use two transformers above 700W to power each channel independently - PCB Dimensions: 280 x 121 x 2mm (LxWxThickness) - Total harmonic distortion: ≤0.01% - Finished board size: 280mm (length)*157mm (width with heat dissipation guide plate)*45mm (height) - Speaker protection circuit: with protection circuit (mute when turn it on/off, midpoint offset, over-current and over-temperature protection) - Output power rating: RCA unbalanced - Signal input method: Class A 150W+150W (4Ω); Class AB 650W+650W (4Ω) Package Included: - 1 x Amplifier Board - 1 x Set of Copper Pillars and Screws - 2 x Temperature Control Tubes - 1 x User Manual Note: - One power amp board with two channels.
