Some questions about Sinbosen D series digital power amplifier

Question

Accepted Answer

Q1. Regarding the D series rear panel switches 1, 2, 3, and 4

Switches 1 and 2: Gain function, the factory default setting is 41dB.

Switch 3: Stereo, Bridge, and Mono. Both Bridge and Mono speaker cables are 1+1-; there's no difference.

Switch 4: Clip limiter. Clip on activates the limiter, which must be on for normal operation and stability.

Q2. Capacitors used in the D series

D4-1500, D4-2000, D4-3000, and D4-4500 capacitors: Fixed Japanese Black King Kong 200V/330UF

D2-4200, D2-3000, and D2-3500 capacitors: We use both Japanese Nichicon and Japanese Black King Kong, but the choice is not fixed

D4-1300: Taiwanese capacitors

Q3. D Series amplifier operating temperature

Can operate in a temperature range of 0-45 degrees Celsius

Q4. Regarding bridging D-series amplifiers

Amplifiers cannot be connected to 2-ohm speakers after bridging, as this will act like a 1-ohm amplifier and could damage the amplifier.

A bridging amplifier can only be connected to 4-ohm speakers.

Q5. How long does it take for the amplifier to enter thermal shutdown?

When using the amplifier's standard fan, the amplifier won't go into thermal shutdown mode.

However, if using a silent fan or a Noctua fan at full DJ power, it will go into shutdown mode after about ten minutes.

Q6. Regarding the US plug selection

One is a standard US plug, the other is an industrial US plug, 15A 125V

Q7. D Series DSP Functions

The D Series DSP's front panel knob controls volume, but if you want to adjust more functions, such as Xover and gain, you must use software.

The software can import FIR functions. FIR is used for phase correction during signal debugging and system adjustment.

Q8. FIR Import Location

Hardware-configure-Load FIR Filter
