QuoteI popped the Sonic IR open and from what I can see it has two major ICs, a Cirrus CS4272 DAC and a HDSC HC32F460JE in a 48 pin flat pack. There are a few additional ICs on the board and two crystals. The Sonic IR has two closely spaced PCBs and you can't pull them apart without desoldering. But there doesn't look like much between them.I can't find much info on the HDSC part, at least nothing in English (the part number may not be right either, hard to read). I wonder if it is a small microcontroller with DSP.
Quotehe HC32F460 series is ahigh-performance MCU based on ARM® Cortex®-M432-bit RISC CPU with a maximum operating frequency of 168MHz . The Cortex-M4 core integrates a floating-point unit (FPU) and DSP to implement single-precision floating-point arithmeticoperations, supports all ARM single-precision data processing instructions and data types, and supports a complete DSP instruction set. The kernelintegrates the MPU unit and superimposes the DMAC dedicated MPU unit to ensure the safety of system operation.The HC32F460 series integrates high-speed on-chip memory, including Flash up to 512KB and SRAM up to 192KB.The Flash access acceleration unit is integrated to realize the single-cycle program execution of the CPU on the Flash. Polling bus matrixsupports multiple bus masters to access memory and peripherals at the same time to improve operating performance. The bus host includes CPU, DMA,USB dedicated DMA and so on. In addition to the bus matrix, it supports data transfer between peripherals, and basic arithmetic operations and events trigger each other, which can significantly reduce the transaction processing load of the CPU.The HC32F460 series integrates a wealth of peripheral functions. Includes 2 independent 12bit2MSPS ADCs, 1 gainadjustable PGA, 3 voltage comparators (CMP), 3 multifunctional 16bit PWM Timers (Timer6) support 6complementary PWM outputs, 3 motor PWM Timers (Timer4) support 18 complementary PWM outputs, 6 16bitgeneral-purpose Timers (TimerA) support 3 3-phase quadrature encoding inputs and 48 Duty independent programmable PWM outputs,11 serial communication interfaces (I2C/UART/SPI), 1 QSPI interface, 1 CAN, 4 I2S support audioPLL, 2 SDIO, 1 USB FS Controller with on-chip FS PHY to support Device/Host.The HC32F460 series supports a wide voltage range (1.8-3.6V), a wide temperature range (-40-105°C) and various low power consumption modes. High-speed mode (8-168MHz) and ultra-low-speed mode (<8MHz) can be switched in Run mode and Sleep mode.Supports fast wake-up in low-power mode, STOP mode wake-up as fast as 2us, Power Down mode wake-up as fast as20us.Typical applicationsHC32F460 series provide 48pin, 64pin, 100pin LQFP package, 48pin, 60pin QFN package,suitable for high-performance motor frequency conversion control, intelligent hardware, IoT connection module and other fields.Huada MCU-China Chip, Chinese Dream Chinese people use their own "chips"• If you have technical and price questions, you can consult with QQ at any time.• Our company has a strong technical team that can conduct R&D and design according to your requirements, and tailor-made , Customer satisfaction is our highest aim~!• QQ:3461816790 •"
QuoteOk, I got into the Sonic IR and replaced a few of the default IRs with a few IRs from OwnHammer and York.I wanted a way to compare, so I left some original IRs in place. I tried an OwnHammer (OH) IR to compare with the onboard Vox and Orange IRS and a York Mesa B. 2x12 vs the onboard Mesa 4x12. That last one wasn't fair, but moving on,... the IRs from OH and York were a big enough improvement to be worth swapping them in. the originals were darker and and a bit more "stiff". Yeah, I could dial down the bass and mid, and raise the treble for the original IR, but with the OH and York IRS the tone knobs all at 12 were great, which gave me more room to adjust them further. Also the OH and York IRs just sound better.So I'd say it's worth it to swap the IR, but keep this in mind. The original IRs (8k to 11k each) took up about 111k of space and left about 126k. OH IRs we're about double, as 26k. York IRs were almost 7 times the size, at around 68k each. So "maybe" you could load 10 to 11 OH IRs, but only a handful of York IRs would fit. The plus to that is you could leave a blanks spots in to kind of act as bypass positions.Conclusion, the Sonic IR is a very good IR pedal, made much better by loading better IRs.
