Answers to customer questions about Sinbosen D series amplifiers
What capacitors are used in the D series?
D4-1500, D4-2000, D4-3000, D2-4500 capacitors: fixed Japanese Black King Kong 200V/330UF
D2-4200, D2-3000, D2-3500 capacitors: Japanese Nichicon and Japanese Black King Kong are both used, not fixed
D4-1300: Taiwanese capacitor
Which sensitivity is better, 41, 38, 35, or 32dB?
32db has a small gain, and some customers may think that the power is not enough. But 32db is the safest
At what temperature can it work?
Can it work in a temperature environment of 0-45 degrees
What are the functions of the 1, 2, 3, and 4 switches on the back panel?
1, 2 switches: Gain function, the factory default setting is 41dB
3 switches: Stereo, bridge and MONO (mono) switching.
Both bridge and MONO speaker cables are 1+1-, there is no difference
4 switches: Clip limiter switch.
Clip on turns on the limiter, which must be turned on for normal operation so that the amplifier is stable. But there is no way to set the limiter parameters.
How long does it take for the amplifier to enter thermal protection?
If the amplifier is equipped with a standard fan, the amplifier will not be muted for thermal protection
But if a silent fan or an owl fan is used, the DJ signal will be protected in less than ten minutes at full power.
About the filter
D series (without DSP) has no built-in filter, the frequency response is flat, no roll-off. Customers need processor adjustment.
