Alpine HDA-M80 amplifier

Alpine has created an all-new "Alpine Status" sound system using the same technical and design concepts used in the third generation AlpineF#1Status Ultra High Definition system to achieve high definition sound at a more affordable price. The Alpine Status system is also extremely flexible: all components can be purchased and used in a "stand-alone" configuration. If you want to create a complete Alpine Status sound system with external amplifiers, we recommend the Alpine Status Class D amplifiers. These amplifiers are developed to perfectly match the Alpine Status speakers and subwoofer to ensure the best sound quality. There is a mono amplifier (HDA-M80), a four-channel amplifier (HDA-F60) and a five-channel amplifier (HDA-V90) with a dedicated high-power subwoofer channel. All controls are conveniently located on top of the amplifiers and protected by a cover plate. This gives you easy access to HP/LP filters and frequency settings, gain controls and input channel selectors (different for each amp model).

Main features

High-Resolution Audio Access - The Alpine Status features many of the technologies, components and materials of the AlpineF#1Status to achieve ultra-accurate music reproduction - at an affordable price. It is designed to play 192 kHz / 24-bit music tracks that are widely available in many online stores and streaming platforms. High-resolution 192kHz / 24-bit audio playback enables Alpine Status to create an elevated in-vehicle listening experience that mimics the feel of an intimate recording studio session.
Excellent sound quality - Alpine Status amplifiers are equipped with many audiophile technologies and selected high-end components to reproduce excellent sound quality.
Alpine Status Full System - contains many components that are optimized for power and performance as a complete system for playback in the intended high definition specification for excellent audiophile sound quality. However, each component can be purchased separately to build your own system.
Sierra-H circuit - after the original analog sound wave is converted to a digital signal and amplified, the Sierra-H circuit compares and corrects the amplified signal twice with the original waveform to reproduce a high-precision signal without any gaps.
Single-sided terminal - all connections (power, speaker outputs, RCA inputs/outputs and bass remote control connector) as well as all fuses are located on the bottom of the amplifier. This makes it much easier to achieve a clean installation in your vehicle.
Thermal protection - along with Alpine's new intelligent amplifier platform, the new Alpine Status amplifiers feature an improved heatsink and protection circuit design that eliminates thermal shutdown for reliable music playback.
Studio recording specification - Alpine Status achieves 192kHz/24bit playback, which is 6.5 times the amount of digital audio data in a standard CD or digital streaming service and exceeds the standard 96kHz/24bit high definition specification found in most audio aftermarket solution. This allows Alpine Status to capture and accurately reproduce details such as a performer's breath or a musician's subtle interaction with an instrument. This capability not only reproduces the music as originally intended by the artist, but mimics the in-vehicle studio recording experience.

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
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.	Digital monoblock
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.	1 x 500 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.	1 x 800 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.	8 - 400 Hz
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.	> 107 dB
High pass filter (HPF)HPF / HP or The "hi pass filter" offers the option of setting the amplifier using a potentiometer so that medium, possibly mid-bass and treble frequencies play upwards from a certain frequency. Example: Amplifiers most often have an HPF from 40 to 300 Hz. If we set the potentiometer to a value of approx. 150 Hz, the sound will be clipped so that it plays frequencies from 150 Hz up to the maximum upper limit of the entire frequency range of the amplifier, perhaps up to 20,000 Hz. We recommend setting this potentiometer in the range of 80-160 Hz. Thanks to this setting option, the speakers can handle a higher performance, as you will not overload them with bass in the lower frequency range.	50 - 400 Hz (24 dB / octt
Low-pass filter (LPF)LPF / LP or "low pass filter" offers the possibility to adjust the amplifier using a potentiometer so that the lower band plays only the frequencies in a certain band that you need. This filter is used to adjust the frequency range for the subwoofer, so that it does not overload or distort the sound. Example: Amplifiers most often have an LPF from 20 to 300 Hz. We recommend setting this potentiometer in the range of 45-80 Hz.	50 - 400 Hz (24 dB / oct)
Damping factorDF - Damping Factor . It is the ratio of the load (repro + cables, crossover, etc.) to the internal resistance of the amplifier. The bigger the DF, the more controlled the bass. Amplifiers with a lower DF tend to hum. Subwoofers with a higher Q in the bass reflex and sometimes in the enclosure will also cause humming.	> 1500
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.	No
