Features

The processor features 2 input channels (A and B) and 4 independent output channels (1, 2, 3, and 4):

• Inputs:

  • Main In: RCA Connection (A and B)

  • High In: Wire Connection (A and B)

• Outputs:

  • Out 1: RCA (L + R)

  • Out 2: RCA (L + R)

  • Out 3: RCA (L + R)

  • Out 4: RCA (L + R)

Input Connections:

• High Connection (Wire): Commonly used in factory car radios and players.

• RCA (LINE) Connection: Commonly used in aftermarket radios and audio equipment.

Digital Processing Features

The processor offers precise audio adjustments through a variety of integrated functions and resources:

• DSP FLOAT MODE: Provides different audio flows and resources.

• INPUT GAIN: Adjustable input gain for precise control.

• GRAPHIC EQUALIZER (Input): 15-band equalizer for detailed sound shaping.

• SUBHARMONIC BASS: Enhances low frequencies for deeper bass.

• OUTPUT MODE: Flexible resource allocation for each output.

• PARAMETRIC EQUALIZERS (Output): Fine-tune frequencies for each output.

• ROUTING: Customizable routing between inputs and outputs.

• HIGH-PRECISION CROSSOVER: Includes Butterworth, Linkwitz-Riley, and Bessel filters.

• HIGH-PRECISION DELAY: Time alignment for optimal sound staging.

• PHASE INVERSION: Adjust phase to eliminate sound cancellation.

• RMS and PEAK LIMITER: Adjustable Threshold, Attack, Hold, and Release settings.

• GENERAL VOLUME, GAIN, and MUTE: Individual control for each output.

• AUTOMATIC SAVE and LOAD: Save and load audio parameters effortlessly.

• SECURITY PASSWORD: Protect your settings with a 4-digit password.

• FREQUENCY GENERATOR and SWEEP: Test and tune your system with precision.

• INTEGRATED SEQUENCER: Remote triggering with configurable timing.

DSP FLOAT MODE

The DSP Floating feature allows the processor to be loaded with different audio flows and resources, expanding the possibilities for configuring various audio systems. Available modes include:

• STD Mode: Includes Input Gain, 15-band Graphic Equalizer, Graphic Equalizer Presets, Parametric Equalizers per Output, Routing, Crossover, Delay/Alignment, Phase Inversion, RMS Limiter, Output Gain, and Mute.

• PRO Mode: Includes Input Gain, Sub Harmonic Bass, Parametric Equalizers per Output, Routing, Crossover, Delay/Alignment, Phase Inversion, Peak Limiter, RMS Limiter, Output Gain, and Mute.

OUTPUT MODE

This feature allows flexible distribution of processing resources across each audio output. You can select the operating mode for each output, adjusting the number of parametric equalizers and the maximum attenuation of crossover filters.

ALIGNMENT (DELAY)

Digitally align transducers (speakers) using time correction in the DSP. This ensures that sound from all speakers reaches the listener simultaneously, avoiding frequency cancellation and improving sound fidelity.

OUTPUT GAIN

Adjust individual output gains in the range of -45dB to +15dB (1dB steps) and control the general volume from 0 to 100dB.
