Zesilovač s DSP procesorem Hifonics ZXR800/8DSP
HiFonics ZXR800/8DSP from the ZEUS Power series is a highly advanced 8-channel amplifier with an integrated 10-channel digital signal processor (DSP) that combines high-quality analog A/B amplification with precise digital audio processing. This model was designed for demanding installations in modern vehicle audio systems where maximum control over the final sound is required.
The amplifier offers eight internal amplification channels and a full-featured 10-channel DSP processor that allows control not only of the internal outputs but also of external amplifiers via RCA outputs. Thanks to this flexibility, the unit can be used as the complete central hub of an audio system—whether a fully active setup with separate tweeters, midranges and subwoofer, or a complex high-end installation with additional power amplifiers.
The digital signal processor operates at high resolution and enables detailed sound tuning via a 31-band parametric equalizer for each output channel. Each band can be adjusted precisely in fine steps, providing maximum accuracy when tuning a vehicle’s interior acoustics. Fully adjustable time alignment for individual channels is standard, allowing perfect sound alignment in the cabin. Advanced active crossovers are also available with adjustable high-pass, low-pass and band-pass sections and selectable filter slopes.
The ZXR800/8DSP model is equipped with a wide range of input options. Available inputs include high-level inputs for connecting to factory head units without RCA outputs, classic RCA inputs, an optical digital S/PDIF input with high-resolution support, and an integrated Bluetooth module. Bluetooth enables not only wireless music streaming but also wireless DSP configuration via the DSP Master app. Alternatively, the device can be configured via USB connection to a PC using specialized software.
The amplifier operates in Class A/B, which ensures a very high-quality and natural sonic character. It delivers stable power to drive speakers in both active and passive configurations. The construction is robust and compact, making installation easier even in the limited space of modern vehicles. An elegant design is complemented by a backlit logo and high-quality connector equipment.
Thanks to flexible signal routing, DSP channels can be assigned to internal amplifiers or routed to external outputs depending on the installation. This makes it possible to build the system step by step and expand it without replacing the main control unit. The HiFonics ZXR800/8DSP is the ideal solution for users who want full control over their car audio sound, whether for detailed stereo imaging, active three-way setups or complex multi-channel installations.

| 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. | A/B |
| 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. | 8 |
| 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 35 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. | 8 x 50 W |
| 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. | 1x 35A |
| 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. | Yes |
| Automatic on and offThis function allows you to automatically switch on the amplifier. | Yes |
| Integrated DSP processor | Yes |
| Number of DSP processor channels | 10 |
| 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 |
| Input for wired remote controlIf the amplifier has a remote control input. | Yes |
| 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 |
