PRV Audio DSP 2.8X 12V 8 Channel Digital Signal Processor

**DSP 2.8X – Digital Audio Processor, Crossover & Equalizer – 2 Inputs & 8 Outputs**

PRV Audio introduces the DSP2.8X Digital Signal Processor, bringing innovation and technology to the automotive sound market. This processor offers a range of real-time signal adjustments, including crossover filters, graphic and parametric equalization, alignment, phase inversion, limiter, audio generator, and more, enhancing your audio system.

Featuring an LCD display and an intuitive interface, the DSP2.8X allows for real-time audio adjustments. It includes 2 audio inputs (A and B) and 8 independent outputs, letting you choose the audio source (A, B, or A + B) for each output. The integrated equalization system offers a 15-band graphic equalizer with manual tuning or 12 presets (Flat, Loudness, Bass Boost, Mid Bass, Treble Boost, Powerful, Electronic, Rock, Hip Hop, Pop, Vocal, and Pancadão).

For professional equalization adjustments, the DSP 2.8X includes a parametric equalizer for both input and output. This feature offers gain control, specific frequency settings, and equalizer bandwidth adjustments, allowing for fine-tuning and detailed equalization control.

The crossover function enables precise definition of cut frequencies, attenuation rates, and filter topology for LowPass and HighPass filters. It supports Butterworth and Linkwitz-Riley filters with options for 12/18/24/36/48 dB per octave.

To protect amplifiers and loudspeakers, the DSP 2.8X incorporates a Limiter with a Dynamic Attack-Release system. This system dynamically controls the attack and release parameters in real-time, ensuring security and sound fidelity.

For audio treatment, the DSP 2.8X offers alignment capabilities through high-accuracy delay, phase inversion, independent gain by output, and master level control. For precise measurements and adjustments, it includes an integrated audio generator with tone generation, frequency sweep, and pink noise. It also supports configuration copy functions between output channels.

Additional features include management, save, and load settings in memory, a security password to lock parameter editing, a marquee/text display, and language selection.

**Sequencer Feature**

The sequencer feature allows sequential triggering of other products via the remote trigger connection (REM). Use a cable of at least 20 AWG. The sequencer includes three outputs (S1, S2, and S3), which are sequentially activated and deactivated based on the input signal from the remote input (REM IN).

The triggering interval between each output can be set from 0 to 4 seconds. If the interval is set to 0 seconds, all three outputs will be enabled and disabled simultaneously, 3 seconds after the REM IN signal changes.
