Your advantages with Masori

Performance of the Nakamichi 4-Channel DSP Amplifier: Everything you need to know about the NDSK-4165AU

When you purchase the 4-channel DSP amplifier NDSK-4165AU from Nakamichi at masori.de, you benefit from numerous technological highlights. The amplifier offers 4x60W RMS power, ensuring powerful, clear sound in your vehicle. Thanks to the dynamic range at the RCA input of ≥100dB and a signal-to-noise ratio of ≥90dB, you'll experience unparalleled audio quality. The wide frequency spectrum from 20Hz to 20kHz will satisfy even the highest demands. See for yourself and experience the Masori Lowest Price Guarantee for a truly affordable shopping experience.

Dynamic range of the NDSK-4165AU: What you can expect at 100dB

The dynamic range of the Nakamichi NDSK-4165AU DSP amplifier is an impressive ≥100 dB at the RCA input. This value describes the ratio between the loudest and quietest sounds the amplifier can handle. A high dynamic range means you can experience both subtle nuances and dynamic sounds with high precision. Compared to other models in this category, the NDSK-4165AU offers an above-average breadth of sound detail. Expanding the dynamic range would theoretically offer more sound nuances, but would require greater technical effort.

Signal-to-noise ratio: More clarity with ≥90dB

The signal-to-noise ratio (SNR) of the Nakamichi amplifier is ≥90 dB. A higher ratio indicates that the amplifier is capable of cleanly separating the desired signal from noise. This significantly improves the quality of music playback by minimizing distracting background noise. In the car hi-fi market, values ​​of 90 dB and above ensure tremendous clarity and detail. Increasing the SNR would provide even greater clarity, but would be hardly necessary in many applications.

Versatile frequency response: Ideal for every style of music

The NDSK-4165AU's 20Hz to 20kHz frequency response enables reproduction of the full human hearing spectrum. This is essential for authentic music reproduction of all genres, as both deep bass and high tones are clearly reproduced. Compared to other models in the same price range, this frequency range is exemplary for high-quality amplifiers. An even wider frequency response would be barely perceptible and therefore unnecessary.

Input impedance: Stability with 240Ω for high-level inputs

The input impedance of the high-level input is 240Ω, ensuring optimal signal processing. Importantly, this impedance is sufficient to establish a stable connection to most original and aftermarket radio systems without signal loss. While a higher impedance value could theoretically result in less load on the signal source, it would be technically complex and rarely necessary in most cases.

Low low level output impedance of ≤100Ω

The low output impedance of ≤100Ω at low-level outputs ensures optimal signal transmission to downstream components such as power amplifiers or active subwoofers. This low value is crucial to avoid signal loss and ensure high coupling efficiency. Compared to other amplifiers, it allows for high-quality sound because unwanted resistance is minimized.

Various input and output options: pure flexibility

Thanks to RCA input signals from 8Vpp and high-level up to 26Vpp, as well as six RCA outputs, the NDSK-4165AU offers versatile connectivity options. This flexibility allows for easy integration into existing audio systems in various cars. Such versatility is exceptional for DSP amplifiers in this class and allows you maximum flexibility in setting up your sound system.

15-band EQ: Fine-tuning par excellence

The built-in 15-band EQ for each channel allows you to fine-tune the sound to your exact liking. The frequency range from 20 Hz to 20 kHz with 1 Hz accuracy allows for precise adjustments. The Q value of the slope can be adjusted from 0.404 to 28.85 – ideal for detailed sound shaping. Such a wide range of adjustments is impressive and offers excellent customization options for sound-loving tinkerers.

High- and low-pass filters: Acoustic control across the entire spectrum

The NDSK-4165AU features professional high- and low-pass filters, including Butterworth, Bessel, and Link-Riley types. The flexible crossover points allow for fine adjustment in the range from 20 Hz to 20 kHz with a resolution of 1 Hz. Thanks to a filter slope of 6 dB/octave to 24 dB/octave, you can precisely tune the amplifier to your speakers. This variability sets the amplifier apart from many standard devices.

Correct phase and time adjustment: Precise sound design

The Nakamichi amplifier offers phase and time adjustments between 0° and 180°, as well as time delay adjustments from 0.000 to 20.000 milliseconds. These options are crucial for accurately timing the sound in the listening room, which is especially essential for the soundstage in complex car hi-fi installations. This precise control would facilitate differentiated adjustments in the event of deviations, but it is already highly competitive.

Dimensions and weight: Space-saving integration

Measuring 174.5 x 120 x 40mm and weighing only approximately 0.7 kg, the compact NDSK-4165AU allows for easy integration into numerous vehicle configurations. Despite its small size, there's no compromise on sound quality. This makes the system particularly attractive compared to other devices, which often require significantly more space.

Presets for individual user profiles

With the ability to store up to six presets on the device, the amplifier offers enormous flexibility for different listening situations or vehicle settings. Whether you prefer a low-bass or a mid-range emphasis, every EQ and filter value can be saved for quick recall. This is a benefit that DSP users particularly appreciate, as it allows for multiple sound profiles to be available simultaneously.
