Attached: Progress for the amplifier's 4-Layer design PCB, lots of small tweaks and core routes are still outstanding. (I wanted a better pcb route strategy so I reworked 90% of original layout, I'm happy with the one I have now.
PCB Progress
- Finalization for all analog + digital signals.
- Bus-supply rails routes has been finalized.
- 70% External modulator + micro-controller pins has been.
- Completed local regulation.
For the DSP Subwoofer.
- Volume: -60dB – 0dB (1dB/step)
- Phase adjust: 0° – 180° (1degree/step)
- Parametric EQ: PEQ Frequency: 20, 22, 25, 28, 30 – 200Hz (1Hz/step)
PEQ Boost: -12.0 – 6.0dB (0.1dB/step)
PEQ Q Factor: 0.2 – 10.0 (0.1/step)
- LP/HP filter: 30Hz – 200Hz (1Hz/step) / LP Slope: 6dB, 12dB, 18dB, 24dB
- Room Gain Comp: N/A (busy with this)
DSP: Typical IIR/FIR structure, 56-Bits, Sampling rates of up to 192 kHz supported.
Subwoofer Amplifier:
- ~ 800 Watts RMS
- Auto switch off
- DC protect
- OV/UV/OT/UT/OC protection
- Analog input fully differential inputs.
Bluetooth controlled + Remote controlled. (Mobile app). (future)
