Most of the car owners' understanding of car audio is mostly focused on speakers. Not only are the speakers more likely to be paid attention to in car audio, but many car dealers often focus on the number of speakers when introducing audio systems, such as the 11 speaker audio system, and the number of speakers is rarely mentioned in the power amplifier driver behind the speakers. However, as the "power" part of the car audio system, the control and driving of the power amplifier are actually very important.
power amplifier is not taken seriously, because many people believe that before the revolutionary breakthroughs in electronic technology and audio electroacoustics today, many power amplifier products are very serious. As for car audio brands around the world, there are only a handful of brands that focus on making power amplifiers well. Among the American car audio brands, many brands leave the impression on the Chinese people that are high-power power amplifiers that drive ultra-bass. However, recently, the old audio brand of the American brand Precision Power, which has more than 30 years of age, has launched the P series power amplifier, which focuses on SQ sound quality style. Its two-channel power amplifier P200.2 is even more unusual, and it has the unique style of Precision Power from appearance to circuit layout and sound performance.
Speaking of appearance, the styling design of the amplifier is only suitable for American
More than ten years ago, when I first entered the automotive audio industry, the US Precision Power was well-known in the domestic SQ sound quality power amplifier products. Among them, the S series has a unique flat and round appearance design and has a unique product ID. Speaking of product styling, overall, American brands are much more dedicated than European ones. Precision Power's newly designed P series power amplifier, all connectors, adjustment knobs, etc. are hidden designs and conform to the current single-sided side-out mode, making the wiring harness connection and adjustment very convenient.
PrecisionPower S2001.D Power Amplifier
The entire power amplifier is stretched with an integrated aluminum piece, and the primary color appearance of the aluminum piece plus the brushing effect is processed. The two side panels are CNC-processed Precision Power's LOGO as the heat dissipation convection channel. The side design hides the power supply and signal connectors, including fuses, etc., which better install and protect the wiring harness.
is no longer a design for bridging bass, the dual mono symmetric design is very SQ
From the perspective of power amplifier debugging and connection, the power amplifier's power supply is connected in the middle, the left and right are the speaker output connections of channel 1 and channel 2, and then the RCA signal access, and the outermost side is the adjustment function of the pre-stage signal processing. The connection of the speaker is not as bridged into a mono amplifier, which is designed with traditional two-channel power amplifiers, and pushes the bass. In a sense, P200.2 is actually completely different from the two-channel design of traditional automotive amplifiers, but pursues high-quality SQ sound quality performance. Traditional two-channel amplifiers are mostly designed for mid-bass or bass, so they can be bridged. Most of the two-channel designs are BTL circuits and can be combined into one. However, from the appearance of the P200.2 design, it is actually a dual mono design, with a shared power input, and other signal processing and amplification are all independent.
abandons complex pre-system processing, less is more HiFi,
0 Turn on the bottom plate of the power amplifier, from the circuit layout, you can see this dual mono layout, and the left and right channels are completely symmetrical, including the power supply part, and it is also a dual-niu design that is independent power supply, and the power supply is 10-16V supply is stable. The signal processing, power amplification levels of the left and right channels are all completely symmetrical, so that the signal separation degree of the left and right channels and the consistency of the left and right channels are optimal.
The entire circuit board adopts an epoxy glass fiber dual-panel design, and the circuit components are all selected from HiFi fever grades, including coupling capacitors, op amps, etc. From the perspective of the entire circuit design, it reflects the HiFi concept that less is more. In the pre-level processing part, you can choose to pass through (Full) without passing the pre-level frequency division processing, etc., which can be connected to the DSP processor that is now essential for automotive audio and is used as a pure rear-level amplifier. In order to have better applications, HP Qualcomm electronic frequency division is also set up, and the frequency of frequency division point is optional from 50Hz-500Hz.The input sensitivity is 0.2v-6v, and the rated output power is 200Wx2 in 4ohm state.
P200.2 The understanding of sound quality lies in: dynamic and linear
has no big dynamics and no fever. In a sense, to fully express the strength and weakness of the music signal, the audio equipment itself needs to have a good dynamic range. In car audio, since you often listen to the audio effects during driving, you need to have a higher power output, which is why the power amplifier of car audio has higher power requirements compared to home use. Precision Power's P200.2 has a sufficient 200W output per channel, which is enough to cope with the top fever speakers and American power amplifier design on the market. It has always had good linear performance under large dynamics, and has also been fully reflected in this P200.2. In other words, whether it is your low-volume playback or your performance at high-volume, it has an excellent balance in the full frequency domain of high-volume, medium-low, and low, making the sound stable and natural.
360 Automobile outlet review: The long-awaited PPI amplifier will not make you wait in vain.
Starting from the Guangzhou Coolpad Electronics Agent Precision Power brand, it has been waiting for the brand's products to be launched in China. From the first P series power amplifier, especially this P200.2, it can be seen that Precision Power attaches importance to China, regains the original concept of this brand, and has a large dynamic linear performance while accurately restoring the tone. The belated PPI amplifier will not make you wait in vain.
