10-channel amplifier with Nakamichi NDST500A DSP processor

Nakamichi introduces its latest DSP processor to its NDST series with built-in amplifier. The NDST500A has been designed with 12 channels that allow perfect integration to factory audio systems including time correction tools and an equalizer to fine-tune vehicle acoustics. Designed from the ground up for Hi-Res Audio, the NDST500A continues the features of the NDS DSP series, which include easy installation on factory systems, Nakamichi head units and other aftermarket units. The NDST500A also comes with a built-in amplifier that provides 10 channels of output power for maximum integration. The included Nakamichi remote control with a large control wheel can be installed on the car dashboard for easy volume, bass and source selection. Music can also be streamed using a Bluetooth connection that completely bypasses the head unit and you can fully enjoy Hi-Res audio without the quality degradation of the factory unit.

About the Nakamichi brand

The history of the Nakamichi brand dates back to 1948, when it was founded in Japan by Etsuro Nakamichi. The journey to fulfilling his dreams began with the establishment of a small research institute, Nakamichi Research Corporation, in Tokyo, Japan, providing sonar and magnet research and development for major brands, government entities, universities and organizations. Since then, it has established itself as a trusted creator of high-quality products that are the result of intensive scientific work, a passion for sound and a commitment to uncompromising quality and performance. In 1972, Takeshi Nakamichi joined Nakamichi Corporation, who was associated with the company's boom at the time and was deeply involved in all of Nakamichi's legendary audio products sold in Asia, America and Europe, including the first launch of the Nakamichi 1000, the world's first cassette tape recorder. He was regarded as one of the world's best acoustic and sound engineers, who was able to combine high-end sound with the genius audio product design strengths of Mr. Koza Kobayashi, the brand's chief engineer at the time. Amplifiers, players, and even car radios of that time are now among the legends for their unsurpassed quality. However, the Nakamichi brand is still successful today and produces high-quality products not only in the field of home audio, but also in vehicles. The ingeniously thought-out portfolio of the manufacturer is constantly growing, and practically all products stand out for their high-quality sound and incredible processing in the given price category. The legacy of Etsuro Nakamichi lives on and we are glad that it is not only a sound name, but also reflected in the quality of Nakamichi products.

Number of amplifier channelsAmplifiers are divided into: - Monoblocks - 2-channel - 3-channel - 4-channel - 5-channel - 6-channel - multi-channel Each channel is used to power one speaker for the coaxial type, or one side if they are component speakers. Monoblock type amplifiers are mainly used for subwoofers. 2-channel are suitable for both subwoofers and, for example, the front pair of speakers in a car. 3-channel is used for front or rear speakers + subwoofer. 4-channel are used for front + rear speakers or 1 pair of speakers + subwoofer. 6 or 5-channel are used for 2 pairs of speakers + subwoofer, most often. Bridging means connecting the amplifier to a bridge, using the + pole from one channel and the - pole from the other channel. In most cases this is shown as "BRIDGED" on the amplifier.	10
Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers.	D
RMS power into 4 ΩRMS power when loading speakers or subwoofer at 4 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier.	4 x 25 W + 4 x 40 W + 2 x 80 / 1 x 300 W RMS
Max. (maximum) power at 4 ΩPeak performance "Max." , which the amplifier can develop for a very short time. A relatively unimportant parameter. It is mainly a marketing move to attract customers to high numbers.	4 x 50 W + 4 x 80 W + 2 x 160 / 1 x 600 W RMS
Frequency rangeThe ability of the amplifier to reproduce the signal from the lowest frequency to the highest = faithfully reproduce the sound in a specific frequency band. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. Since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even specify this maximum tolerance of sound pressure in decibels in their catalogs for reasons of prestige. Data impoverished in this way is unfortunately worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness or undulation of the frequency curve in good speaker systems for high-quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural.	20 - 20,000 Hz
Harmonic Distortion (THD)Total harmonic distortion indicates how much the input signal is distorted in the amplifier. Distortions appear as overtones contained in the output signal. The proportion of originally absent parts of the signal is given as a percentage, typical values are between 0.001% and 0.5%. Distortion is measured in their power band. If it exceeds the limit of 0.7% from a certain power, it is the value of the output power of the given amplifier, from which it no longer plays without distortion and from which the distortion usually increases steeply, so that no further increase in power can be counted on. The lower the value, the better.	≤0.05%
High level inputsThe high-level input on the amplifier allows connection directly to the existing speakers in the car without additional purchase of an external high/low adapter. Important equipment in the case of installing an amplifier on an original car radio.	Yes
Remote control included in the packageSome models of amplifiers also come with wired remote controls in the package, which on one side plug into the amplifier and on the other side you have a potentiometer that you can place anywhere in the cabin. A common place to place the remote control is under the steering wheel. The advantage is the regulation of power, and therefore volume, depending on driving conditions and the mood of the crew in the car.	Yes
