DP-408 4-In 8-Out Digital Audio Signal Processor

The LYINTL DP-408 is a professional digital audio signal processor & speaker management system designed for commercial audio systems, conference systems, performance venues, karaoke installations, houses of worship, bars, theaters, and multi-purpose halls. Powered by a high-performance 32-bit DSP processor and advanced 24-bit A/D and D/A converters, the processor delivers exceptional audio quality with 96kHz sampling accuracy for precise sound management and optimization.

The DP-0408 provides 4 balanced audio inputs and 8 balanced audio outputs, enabling flexible routing and advanced loudspeaker management for complex audio systems. The series is also available in 2×4 (DP-204), 2×6 (DP-206), and 4×6 (DP-406) configurations, allowing system designers to select the ideal model for various project requirements.

Each input channel is equipped with a 31-band Graphic Equalizer (GEQ) and a 10-band Parametric Equalizer (PEQ), while each output channel features a 10-band PEQ. Comprehensive processing functions include gain control, phase adjustment, delay, crossover, limiter, mute, and routing matrix management.

The processor supports multiple crossover filter types, including Bessel, Butterworth, and Linkwitz-Riley filters with selectable slopes up to 48dB/octave, making it suitable for professional loudspeaker systems, subwoofer management, and multi-way audio configurations.

Up to 12 user presets can be stored and recalled instantly for different venues and operating scenarios. USB, RS232, and RS485 control interfaces provide flexible local and remote system management, while the front-panel LCD display offers intuitive operation and monitoring.

With powerful DSP processing, comprehensive loudspeaker management capabilities, and reliable system control, the DP-0408 is an ideal solution for professional audio installations requiring precise signal processing and maximum system flexibility.
