parallel +BTL TDA7293 Acura power amplifier Board
( the power amplifier Board is 350W single channel-amplifier Board after) .
n The original TDA7293 and NE5532
n Front input capacitance coupling capacitance between stages and vinyl top polypropylene capacitors 2.2UF, electrolytic capacitors signal primary circuit using Taiwan brand-name
n Resistance selection of rings of metal resistance, main circuit using precision metal film resistors ± 1% ring to ensure good signal to noise ratio of the whole machine. ≪/span>
n The amplifier Board is stable and reliable, high-power output; sound beautiful and mellow, sound field open. Grills, low frequency sound solid and strong, signal to noise ratio is excellent, wide dynamic range; details clear, excellent transient response, and play all kinds of music are well
Output power: 350W (4 euro) ≪/span>
Note : This power amplifier Board contains no rectifier, DC input voltage +-30V, please add in your AC power rectifier circuit. Special attention to the capacitors on the power Board to discharge and power amplifier Board connection, +-cannot be reversed, IC metal parts grounding, burn IC does not warranty!
