2DIN car radio with 9" display Nakamichi NAM5730-A9

Nakamichi NAM5730-A9 is the highest model of this Japanese manufacturer's car radio. With Nakamichi's redesigned operating system paired with an 8-core processor, the Nakamichi NAM5730 car stereo is ready to deliver superior sound and a latency-free user experience in all your preferred apps while driving. With a built-in professional digital signal processing (DSP) chip and support for 5.1-channel audio, you can personalize every listening experience and customize it to your taste with a powerful equalizer, presets and time delay processing tools. DSD support allows you to enjoy SACD-like music quality without the need for an external music player. The Nakamichi NAM5730-A9 can boast of huge equipment, led by a large 9" HD touch screen in a standard 2 DIN chassis. To install a car radio with such a large display, however, it is necessary to purchase an installation adapter according to your car model. The extensive equipment includes, of course, an AM/FM radio, Bluetooth for music streaming and phone calls, USB input, Wi-Fi, 5.1 4V RCA outputs for connecting an external amplifier, the possibility of connecting a parking camera or playing FullHD and 2K movies. An interesting feature is the built-in storage with a capacity of 32 GB and all this on the Android 9.0 operating system. We particularly appreciate the built-in DSP processor, on which you can set bandpasses, phases, steepness, time corrections and a 48-band equalizer in great detail. The ability to play Hi-res music will also please you.

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.

Car radio sizeCar radios are divided into 2 basic sizes, 1DIN car radios and 2DIN car radios .

1DIN size car radios - the exact dimensions including the metal frame where the car radio is inserted are 184 x 53 mm, the external dimensions of the branded 1DIN car radio are 188 x 59 mm.

We know 2DIN car radios from newer vehicles, a classic example is the VW Golf IV with navigation. The dimensions of a 2DIN car radio without a metal frame are 180 x 101 mm, the external dimensions of a branded 2DIN car radio are 189 x 119 mm.
2DIN
Car radio performanceThe performance of the car radio shown in maximum values. This is therefore the MAX value. The performance of the internal amplifier of the car radio. Today, the RMS power of a car radio ranges from 17 - 30 W RMS per channel. 4 x 50W
Supported formats via USB inputList of all supported formats (MP3, AAC, Flac, DivX, etc.) that the car radio can play via USB input. MP3/WAV/AMR/APE/AAC/FLAC/ H264/MP4/MOV/AVI/MKV/FLV
USB inputThe USB input of the car radio is used to connect a USB flash drive or smartphone. Today, playing music via USB is the most popular way to listen to music in the car. The USB input can be front (on the front panel of the car radio) or rear (on the back of the cable). Yes
CD driveCar radios with CD drive. Car radios that have an input slot for inserting a CD. No
SD card accessModern branded car radios can play SDHC SD cards up to 32 GB, sometimes even 64 GB. The SD card slot is behind the front panel in most car radios. No

Integrated BluetoothBluetooth is a communication technology used for wireless connection between two or more electronic devices. A mobile phone, for example, can be connected to a car radio with built-in Bluetooth. Most car radios for 2017 and later can also wirelessly stream (play) music via Bluetooth -> A2DP function. Yes
Audio Streaming via BluetoothA2DP (Advanced Audio Distribution Profile) is a Bluetooth profile that enables the wireless transmission of stereo audio from an A2DP source, typically a mobile phone or computer, to an A2DP receiver (car radio). These devices usually also support the AVRCP profile. Yes
External microphone included in the packageThe external microphone is connected from the back of the car radio to the input marked "MIC". For ideal sound quality during a phone call, we recommend placing the external microphone on the left "A" pillar at the point where the "A" pillar and the roof panel connect to each other. A very good position to place an external microphone is also near the central rear-view mirror. No
Number of RCA outputsRCA outputs , colloquially called "cinches", are used to connect an external amplifier or active subwoofer. Aftermarket car radios are usually equipped with 1 to 3 pairs of RCA outputs. FRONT, REAR and SUB are used.

It also depends on how many volt outputs the car radio is equipped with. More basic models of car radios have 2V outputs, more expensive units have 4V and more. The higher the specified value, the less power demands are placed on the external amplifier and the sound quality increases.
5.1
Output level on RCAAn important parameter if you are going to install an external amplifier. If you purchase a car radio with a basic value, i.e. 2V outputs, then greater demands will be placed on the power of the amplifier. As the value increases, e.g. 4V or 5V, the power of the external amplifier increases significantly, in layman's terms.

A car radio with strong outputs therefore has the advantage that you do not pull so much power through the amplifier and thus achieve a better sound, as external amplifiers lose control at higher loads.
4 V
