OverviewMOSCONI PRO 8|30 DSP EVO
Eight Channels. Pure Analog Power. Digital Precision.
EIGHT ANALOG AMPLIFIER CHANNELS. TWELVE DSP CHANNELS. ONE INTEGRATED DESIGN.
The MOSCONI PRO 8|30 DSP EVO combines eight high-quality Class AB amplifier channels with an integrated 12-channel digital signal processor. Its architecture brings together analog power amplification and advanced digital signal processing in a single unit designed for demanding fully active car audio systems.
Four amplifier channels deliver 90 watts RMS each, while the remaining four provide 170 watts RMS each at 4 ohms. This asymmetric power distribution allows the amplifier channels to be assigned according to the requirements of individual loudspeakers. The lower-powered channels can drive tweeters and midrange speakers, while the more powerful channels provide additional headroom for midbass drivers and other demanding loudspeakers.
With bridged operation available at 4 ohms, the PRO 8|30 DSP EVO can be configured for different system architectures. Four additional DSP-processed RCA outputs allow external amplifiers to be integrated into the system, extending the available output channels without requiring a separate signal processor.
ANALOG CLASS AB TECHNOLOGY WITH N-CHANNEL MOSFET OUTPUT STAGES
The PRO 8|30 DSP EVO uses eight analog Class AB power amplifier stages. Its output stage architecture employs two identical N-channel MOSFETs, allowing a symmetrical circuit design for the positive and negative signal paths.
This amplifier topology is designed for accurate signal amplification and controlled output stage behavior. With total harmonic distortion below 0.05% at 4 ohms, measured at 1 kHz and 90% of rated output power, the amplifier provides verified low-distortion performance under the specified measurement conditions.
The analog amplifier architecture provides the foundation for accurate reproduction of complex musical signals, while the integrated DSP allows each loudspeaker channel to be individually optimized for its position and operating range.
HIGH-PERFORMANCE PUSH-PULL SWITCHING POWER SUPPLY
A stable and appropriately dimensioned power supply is an essential part of a high-performance multi-channel amplifier.
The PRO 8|30 DSP EVO features an unregulated push-pull DC/DC converter operating at a switching frequency of 50 kHz. This topology uses alternating switching stages to transfer energy from the vehicle's electrical system to the secondary supply rails required by the analog output stages.
The push-pull configuration provides an efficient method of voltage conversion and supports the substantial combined power requirements of the eight Class AB amplifier channels.
Designed for an operating voltage range of 10 to 16 volts, the power supply is equipped with an integrated 150 A fuse. Thermal monitoring provides additional protection during demanding operating conditions.
The amplifier also supports temporary voltage drops associated with modern vehicle start-stop systems, with operation specified down to 7.5 volts for up to 300 milliseconds.
FOUR-LAYER PCB DESIGN AND HIGH-QUALITY CONSTRUCTION
The internal construction of the PRO 8|30 DSP EVO is designed to accommodate the electrical and thermal requirements of a powerful analog multi-channel amplifier.
Its four-layer FR4 printed circuit board uses 70 µm copper, providing the necessary conductor capacity for the amplifier's power circuitry. The multi-layer construction also offers additional flexibility in the routing and arrangement of power, ground, and signal connections.
A matte black solder mask, gold-finished PCB surfaces, and gold-plated connection terminals complement the internal construction.
Temperature-controlled ventilation supports thermal management during operation. The cooling fan activates at 50°C and switches off again at 45°C. Additional thermal protection circuitry monitors operating temperature and protects the amplifier against overheating.
ADVANCED 12-CHANNEL DSP WITH 96 KHZ / 24-BIT PROCESSING
At the heart of the PRO 8|30 DSP EVO is a powerful 12-channel digital signal processor operating at a sample rate of 96 kHz with 24-bit resolution.
All twelve DSP channels can be configured individually. Each channel provides 30 bands of parametric equalization, along with comprehensive high-pass, low-pass, and band-pass filtering options.
Filter slopes can be cascaded up to 60 dB per octave, allowing precise control of the operating frequency range of each connected loudspeaker.
Time alignment can be adjusted from 0 to 15 milliseconds in increments of just 0.01 milliseconds. This allows differences in loudspeaker distance and installation position to be compensated during system tuning.
Individual phase inversion, adjustable Q factors, and extensive gain control provide additional flexibility when optimizing complex multi-way loudspeaker systems.
Four stored DSP presets allow different sound configurations to be recalled, making it possible to optimize the system for different listening positions or personal preferences.
With eight internally amplified channels and four additional DSP-processed analog outputs, the PRO 8|30 DSP EVO provides extensive signal processing capabilities for sophisticated active car audio installations.
INDIVIDUAL INPUT CONFIGURATION VIA DIP SWITCHES
A distinctive feature of the PRO 8|30 DSP EVO is the individual configuration of its analog input stages using DIP switches.
Each input can be configured according to the connected signal source and the electrical characteristics of the vehicle's audio system.
In addition to conventional low-level RCA signals, the amplifier accepts high-level signals with selectable input sensitivities of 15 or 30 V RMS.
The high-level input circuitry also supports autosense functionality for automatic turn-on detection. Selectable input impedance configurations and ground reference arrangements allow the amplifier to be adapted to different factory head units and OEM amplifier outputs.
Support for Class SB high-level signals further extends compatibility with suitable factory audio systems.
The DIP switch configuration provides clearly defined and repeatable settings, making the amplifier particularly suitable for installations requiring individual channel configuration.
FLEXIBLE INTEGRATION INTO MODERN AUDIO SYSTEMS
The PRO 8|30 DSP EVO offers a wide range of connection options for aftermarket and factory-installed audio systems.
In addition to its analog inputs, the amplifier features an optical Toslink digital input and an EXT_CARD interface for compatible expansion modules.
DSP programming and configuration are performed through the USB-C connection, providing access to input and output routing, crossover settings, parametric equalization, time alignment, and other processing functions.
Compatible MOSCONI remote controls, including the DSP-RCD, DSP-RC mini, and GLADIATOR, can be integrated for convenient system control.
Combining eight analog Class AB amplifier channels, twelve individually adjustable DSP channels, and flexible input configuration, the MOSCONI PRO 8|30 DSP EVO provides a versatile foundation for demanding active car audio systems.
