6.1. RCA to HDMI Converter Operation

Once connected and powered, the converter will automatically scale the analog RCA signal to 1080P or 720P HDMI output. The primary operational control is the aspect ratio switch.

• Aspect Ratio Switch (4:3 / 16:9): Use the physical toggle switch on the converter to select the desired display aspect ratio. This helps restore the original output ratio of older DVD/VCR players.

6.2. Optical to RCA DAC Converter Operation

The DAC converter operates automatically once connected and powered, converting the digital optical signal to analog RCA. The critical step for proper operation is configuring the audio source.

• Setting Audio Output to PCM: The converter is designed for PCM (Pulse Code Modulation) stereo audio. If your source device outputs Dolby AC3, DTS, or other multi-channel formats, you will not get sound. You must change the audio output setting on your source device (e.g., TV, Blu-ray player) to PCM.

General steps to set PCM output (may vary by device):

1. Go to your device's (e.g., TV, Blu-ray player) Тохиргоо цэс.
2. руу шилжих Дуу or Аудио тохиргоо.
3. Хай Мэргэжилтнүүдийн тохиргоо or Нарийвчилсан аудио тохиргоо.
4. Хай Дижитал аудио гаралтын формат or Аудио формат.
5. Сонго PCM (or Stereo) from the available options.
