The above is the customer feedback of the D4-3000 digital amplifier and KA210 dual 12-inch line array speaker sound combination scene!


KA210 is Sinbosen's hot-selling line array speaker with high sound performance. When the dual 10-inch speaker uses the 4+2 solution, that is, 4 line arrays plus 2 subwoofers, it can cover 500-1000 people, which is in line with the customer's expected number of people on site. The customer bought 4 sets of 210 and only needs one D4-3000. D4-3000 has 4 channels, one channel can be connected to 2 sets of KA210, and the remaining two channels can be connected to subwoofers (note that D4-3000 works at 2ohms not recommended for subwoofers, but the 2-channel D-Series is fine.)


The D4-3000 digital amplifier further improves the cooling system, with the fan raised to 0.55A, giving the D4-3000 a higher power output at lower temperatures and better results when working under 2 ohms. The D4-3000 has carefully selected power amplification transistors for faster speeds and greater power. Transformers have also been improved to withstand greater power. All the details make D series amplifiers more powerful and have better sound quality.
