1. Introduction
The Insignia NS-HZ313-C Optical/Coaxial Digital-to-Analog Audio Converter is designed to convert digital audio signals from optical (Toslink) or coaxial sources into analog stereo audio. This allows you to connect modern audio devices with digital outputs to older audio systems or headphones that only accept analog RCA inputs. It supports PCM stereo audio format.
This manual provides instructions for setting up, operating, and troubleshooting your digital-to-analog converter.

4. Setup and Connection
Follow these steps to connect your Insignia Digital-to-Analog Converter:
- Prepare your audio source: Ensure your audio source device (e.g., TV, game console, Blu-ray player) has either an optical (Toslink) or coaxial digital audio output.
- Connect Digital Input:
- If using an optical cable (not included), connect one end to the optical output of your source device and the other end to the OPTICAL IN port on the converter.
- If using a coaxial cable (not included), connect one end to the coaxial output of your source device and the other end to the COAXIAL IN port on the converter.
- Connect Analog Output: Connect the included RCA stereo audio cable to the L AUDIO R OUT ports on the converter. Connect the other end of the RCA cable to the corresponding analog audio input ports (typically labeled "Audio In," "Aux In," or "Line In") on your amplifier, receiver, or powered speakers.
- Select Input Source: Use the COAXIAL/OPTICAL switch on the side of the converter to select the digital input you are using.
- Connect Power: Plug the AC power adapter into the DC 5V port on the converter, then plug the adapter into a standard wall outlet. The LED indicator on the converter should illuminate.
- Configure Audio Source: It is crucial to set your audio source device's digital audio output format to PCM stereo. This converter does not support Dolby Digital or DTS formats. Refer to your source device's user manual for instructions on how to change its digital audio output settings.
Important Note: This converter only processes PCM stereo audio. If your source device is set to output Dolby Digital, DTS, or other multi-channel formats, you will not get sound. Always ensure your source device's digital audio output is set to PCM.
5. Operation
Once all connections are made and the power is supplied, the converter operates automatically.
- Ensure the COAXIAL/OPTICAL switch is set to match your active digital audio input.
- Play audio from your source device.
- Adjust the volume on your connected amplifier, receiver, or powered speakers.
The converter will convert the digital PCM stereo signal to an analog signal, which will then be output through the RCA ports to your analog audio system.
