In fact, a whole digital subsystem was built around HiBy's uber-affordable dongle. FC4 boasts a FPGA working in tandem with two clocks to supply its ES9218PC DACs a clean I2S input.
HiBy derive an overbuilt clocking system this way, pushing down phase noise and reducing jitter even at this form factor.
FC4's USB-C receiver is also of excellent quality to run an excellent asynchronous signal from your phone, tablet or computer, and its powerful DSP works in tandem with the FPGA to preserve the integrity of your music data for decoding.
Additionally, HiBy's onboard volume control buttons ensures you can run a true 8 times MQA even from portable Android devices, with sample-rate indication lights confirming it.
This portable powerhouse comes with a detachable cable and can be adapted for a range of mobile applications, from smartphones to iOS Lightning and laptops. Also browse the rest of HiBy's options here, or our other DAC/amps here.
