CIRCUIT OPERATION MANUAL
PCM Timing
Analogue Audio Signals that are modified at Audio DAC are amplified by three times after going through Low Pass
Filter. The output is made after the amplification through AV Switch or Buffer.
2) Digital Audio(SPDIF Format)
Use PCM1754/Texas Instruments which are IC of the Digital Audio Encoding system in SPDIF format. The signals are entered
from the PCM Format (I2S Format).
The Digital Signals that were encoded in SPDIF go through driver circuit, then the output is placed in the RCA unit.
This output will be connected with Digital Audio Devices.
