Digital power amplifiers have several distinct features, such as small size, light weight, high efficiency, low calorific value, and high power. The sound is less distorted than the analog power amplifier of the same price, the sound is loud and powerful, and the digital signal will not bring phase delay, phase distortion, crossover distortion, etc. during the transmission process. The advantage of hearing is that the sound will be more transparent, the positioning will be more accurate, and the sound will be closer to reality. More and more people like digital power amplifiers, and they are more and more widely used in various professional places!
In the past, Sinbosen had K4-450 (4-channel 450W), K4-1400 (4-channel 1400W), K4-1700 (4-channel 1700W) and other 4-channel digital power amplifiers, as well as K-800 (2-channel 800W), K-1000 ( 2-channel 1000W), K-1200 (2-channel 1200W) and other 2-channel digital power amplifiers. The parentheses are the output power under 8Ω impedance. However, there are many customers who need 4 channels and ask: why there is no K4-800, K4-1000?
This is a good question. So now, Sinbosen is putting K4-800 (4 channels 800W), K4-1000 (4 channels 1000W) on sale! Like K4-450 and K4-1400, K4-1700, we will also plan to put K4-800 and K4-1000 Add to overseas warehouses in Mexico, USA and Europe! K4-800 and K4-1000 are very suitable for full-range speakers, special monitor speakers, 4 channels can be connected to a single 15-inch monitor speaker per channel.

K4-SERIES : 1U 4-channel power amplifier, small size, light weight, easy to install. The circuit uses a Class D power amplifier module, a reliable and efficient R-SMPS stabilized power supply system, which has extremely high efficiency and controllability, and also has extremely high power density, which can adjust the current waveform according to the AC voltage waveform. Wide voltage operation, adapt to the global scope, can carry higher power.

Features of all K4 series digital power amplifier:
1. Use Class D power amplifier module. Unique peak clipping limiter and ripple reduction. 
2. The perfect protection system effectively reduces the losses caused by improper use. 
3. The perfect circuit design makes the bass strong and powerful, and the mid and high frequencies are transparent and clear.
4. 1U design, its light weight and very small space occupation rate.
5. It is widely used in large and medium-sized bars, banquet halls, and outdoor performances.
Now we also have few client feedback about the 4 channels digital amplifier K4-800 feedback.

In addition, there is a new dsp power amplifier on sale recently, the model name is LA12X.
The LA12X (4 channel 1850W at 8 ohms) is Sinbosen's new series of DSP power amplifiers, and the same series also has the LA8 (4 channel 1450W at 8 ohms).
The following is their Dsp software interface, the operation is simple and convenient!
