Features: The TAS5630 ClassD amplifiers can provide a stereooutput power of 300W+300W under a DC48V 4ohm load. Rectification and filtering capacitors, and filtering capacitors should not be lower than 22000UF, otherwise the impures power will affect thesignals-to-noiseratio. DC20-50V power 300W+300W highspower highfidelity double-channel sound quality TAS5630 Power Amplifiers Board delivers distortions frees sound with its low output offsets voltages and highconversion rate. Immerses yourself in clear with this board. Specifications: Material:ABS Total harmonics distortions (THD+N):<1% Signal to noiseratio :>100dB Input impedance: 20KΩ Output offsets voltages: ＜150mV Voltages gain: adjust Conversion rate: 50V/us Frequency response: 20Hz --20kHz Power: DC20-- DC50V (recommend 20-45Volt, not recommend for use under extreme voltages of 48-50V) Size:Approx.101.6mm/4''x99mm/3.88'' Package Includes: 1x Digital Amplifiers Board note: Please allow 1mm errors due to manual measurement.
