Macrom M-DSPA500 amplifier with DSP controlled smartphone app for music streaming

Improving the sound of your original car audio system has never been easier or faster. The Macrom M-DSP500 comes with a cable designed for your vehicle that connects it between the original car stereo and the speakers. The power supply is provided without any problems via a cable harness or a separate power supply from the car's car battery. The amplifier automatically turns on when an audio signal is detected from the source. The control uses a Bluetooth connection to the amplifier and allows settings to improve the sound according to the specific response of the car and your preferences. Compact dimensions allow for easy installation.

Optimal sound for all situations

The app for controlling the M-DSPA500 is free and can be downloaded from the Google Play store or the Apple store. By activating the Bluetooth connection with the M-DSPA401, it allows you to set all the main parameters of the sound processor, allowing you to optimize and customize the sound performance of the system. The app allows you to save up to five custom settings. The heart of the M-DPSA500 is a 5-channel analog amplifier, providing four 54 W class AB channels and one 300 W class D channel for the subwoofer.

A2DP Bluetooth music streaming

By activating the Bluetooth audio connection, it allows you to play music files in high quality using the A2DP audio streaming function. Using mobile device applications, you can listen to the content of your mobile phone or player, as well as Spotify, Apple music, Google play music, etc.

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.

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 32 + 1 x 170 W
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 54 + 1 x 300 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 - 20000 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.
0,001 %
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. > 120 dB
