2.Power Amplifier Module Functionality
- Dual analog inputs → single output channel architecture.
- Processed by a 24-bit DSP chip at 48kHz sampling rate with independent 24-bit A/D and D/A converters.
- Input Channel Processing includes gain adjustment, low-cut filtering, muting, phase alignment, FIR filtering, etc.
- Output Channel Processing Units feature crossover functionality, 11-band parametric EQ, gain control, muting, compression/limiter, phase shifting, delay effects.
- All PEQ bands support continuous adjustment of gain, bandwidth, frequency; selectable modes include Parametric EQ, Low Shelf, High Shelf, Low Cut, High Cut, First-order Phase Shift, Second-order Phase Shift.
- High/Low Cut filters offer Butterworth/Linkwitz-Riley/Bessel responses with slope adjustable from -6dB to -48dB.
- Compressor/Limiter threshold, ratio, attack time, release time & knee values are fully adjustable.
- Real-time visualization of all input/output PEQ curves accessible per channel; default split-frequency mode for stereo output.
- Advanced FIR processing capability supports up to 512 taps for automatic speaker response & phase correction.
- Seamless compatibility with third-party applications via import of .CSV and .TXT files.
- User-defined parameter presets storable in DSP memory; instant recall via front panel rotary encoder.
- Compact Class D topology integrates switch-mode power supply for ultralight weight.
- High-efficiency conversion delivers high output power while minimizing energy consumption (eco-friendly design).
- Precision gain management on front panel; LED indicators for Power/Signal/Protection/Clipping status.
- Robust protection circuitry safeguards against DC faults, thermal overruns, overcurrent conditions & output clipping.
