Hifonics ZXS550/2 amplifier
Classic ZEUS amplifiers used to be analog. Large ZEUS amplifiers are still revered by car hi-fi fans around the world, but the disadvantage of these amplifiers is that they take up a lot of space in the vehicle. For this reason, Hifonics engineers made a decision when designing the new amplifier ZEUS STREET ZXS rely on advanced digital performance to achieve ultra-compact cooler dimensions. First of all, this is possible thanks to modern Class D technology, which, due to the enormously high efficiency that can be achieved, requires 90% less current than analog amplifiers of comparable performance. Another advantage - the cross-sections of the cables for the power supply do not have to be so strong. As soon as you unpack the amplifier, you will realize that you are dealing with genuine ZEUS amplifiers. Despite the small dimensions, the models are pleasantly heavy in the hand and convey a solid feeling in the usual quality of the Hifonics brand. Embossed aluminum logo badges, carefully milled model numbers and sophisticated cast aluminum end caps visually convey the unique symbiosis of power and elegance that these amps exude. Of course, all ZXS models, in addition to adjustable switches, have the latest features, such as automatic switching, which is needed to connect to modern vehicle electronics. High-level inputs are equipped with advanced EPS to suppress error messages in the vehicle's diagnostic systems. HiFonics IFT low-emission digital technology ensures undisturbed radio reception.

| 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. | 2 |
| 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. | 2 x 150 / 1 x 550 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. | 2 x 275 W |
| 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 - 500 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. | < 0,02 % |
| 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 |
| 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. | 5 - 0,2 V |
| High level inputsThe high-level input on the amplifier allows connection directly to the existing speakers in the car without additional purchase of an external high/low adapter. Important equipment in the case of installing an amplifier on an original car radio. | Ano |
| Automatic on and offThis function allows you to automatically switch on the amplifier. | Ano |
| 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. | Ano |
| 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. | Ano |
| Input for wired remote controlIf the amplifier has a remote control input. | Ano |
| 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. | 1 x 50 A |
