Nakamichi FHE120.4 Amplifier

The Nakamichi FHE120.4 is a powerful 4-channel amplifier designed with a focus on audiophile quality, pure performance, premium internal components, and sleek design. With carefully selected components like Hi-Fi power transistors, low-noise operational amplifiers, capacitors, and versatile silver-plated output terminals made of pure copper, it stands out in its class. The amplifier offers an output power of 4 × 120 W RMS into 4 Ω and can handle 2 × 300 W into 4 Ω in bridged mode. It is an ideal solution for connecting speaker systems or subwoofers in high quality. Precise volume control and reliable regulation are managed by a silver-plated potentiometer, and cooling is ensured by an aluminum alloy body with a robust construction. Inside, you'll find a copper transformer for stable power supply, quality signal path, and clean amplification even under higher loads. The output terminals and RCA connectors are designed with minimal transitional resistance and maximum conductivity. With its combination of precise electronics and focus on sound quality, the FHE120.4 model is an ideal choice for demanding users looking for a powerful yet clean-sounding amplifier for quality car audio.

About Nakamichi

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 the Nakamichi Research Corporation in Tokyo, Japan, which provided research on sonars and magnets and development for major brands, government entities, universities, and organizations. Since then, it has established itself as a trusted creator of high-quality products, resulting from intense scientific work, a passion for sound, and a commitment to uncompromising quality and performance. In 1972, Takeshi Nakamichi joined Nakamichi Corporation, linked to the company's then-expansion and deeply involved in all legendary Nakamichi audio products sold in Asia, America, and Europe, including the first introduction of the Nakamichi 1000, the world’s first cassette deck. He was regarded as one of the world's best acoustic and sound engineers, capable of combining top-notch sound and the advantages of the brilliant design of audio products by Koza Kobayashi, the brand's then-chief engineer. The amplifiers, players, and car radios of that time are considered legends today, yet the Nakamichi brand remains successful, producing products in the home and vehicle audio sectors. The manufacturer's thoughtfully designed portfolio continues to expand, offering an intriguing balance of price and quality. Particularly the higher model ranges strive to continue the legacy of Etsuro Nakamichi, whose name is still reflected in the brand's products today.

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.	AB
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.	4
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 120 / 2 x 300 W
RMS power into 2 ΩRMS power when loading speakers or subwoofer at 2 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier.	4 x 170 W
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 - 32000 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.	< 0.2 %
Signal-to-noise ratioThe signal-to-noise ratio means that the output signal always contains noise. The signal-to-noise ratio expresses how much of this noise is compared to the useful signal. The so-called A value is given, which does not take deep and very high frequencies into account. This corresponds to the characteristic of human hearing, which is not so sensitive to deep frequencies, especially below 1 kHz. The higher the value, the better the amplifier is.	> 102 dB
Input sensitivityIn order for the amplifier to perform its function correctly, it requires an input signal of a certain level, which is different for car radios. It is measured in "Volts" (e.g. 2 V, 4 V, etc.) The higher the value at the output of the pre-amplifier, or car radio, the less demands are placed on the power of the amplifier. However, the amplifier must allow this input sensitivity, and for that reason this value is also given for the amplifier.	0.35 - 9V
The value of the fuses on the amplifierFrom the value of the fuses on the amplifier, you can get a true picture of the real performance of the amplifier.	2 x 40 A
Automatic on and offThis function allows you to automatically switch on the amplifier.	Yes
Socket input terminalsFerrule terminals allow better wiring contact to the amplifier. It is also a more secure form of terminals. If you are tightening the sleeve terminals, we recommend retightening them after 1 day, as the connected cable gradually compresses.	Yes
