![]() ![]() That program controls the Crystal system through emulated I2C bus. A program for PIC12F509 microcontroller was written in Assembler. CS8420 needs to be configured properly and its work should be supervised. CODEC is clocked by a DSP clock with a frequency of 384*Fs. From DSP the signal goes to CS8420 via I2S to the optic transmitter. Then the signal goes through the I2S bus to DSP. ![]() In this case, digital signal from the IR receiver goes to the sample frequencies converter (just in case Fs was different from 44,1kHz used in DSP). It has a receiver and transmitter SPDI/F, two audio ports and a sample frequencies converter, all configurable in different ways. You should use service instruction for SH-GE90 (scheme) and specification of the A/D and D/A converters that are located in the corrector. Due to the improvement of the quality of the audio track, you can get rid of so frequent digital-analogue and analogue-digital conversion. Thus digital audio sound from CD is converter in the D/A converter to analogue, then again sampled in EQ and after the signal processing, re-changed. It means that using CD player with TOS-LINK output, you have to use analogue stereo output. SH-GE90 from Technics), which despite the digital signal processing does not have digital audio inputs and outputs. It is a useful device for owners of a digital equalizer (e.g.
