1. Introduction
This manual provides instructions for the proper use and care of your RadioShack 9-Inch Y-Adapter Audio Cable. This cable is designed to split a single 3.5mm stereo audio output into two RCA (left and right) audio channels, allowing connection to a wider range of audio equipment such as amplifiers, receivers, or speakers.
Please read this manual thoroughly before using the product to ensure optimal performance and longevity.

4. Setup and Connection
Follow these steps to connect your Y-adapter audio cable:
- Identify Connectors:
- The single 3.5mm (1/8-inch) stereo plug is typically connected to the audio output of a portable device, computer, or headphone jack.
- The two RCA plugs (usually red and white/black) are connected to the audio input jacks of an amplifier, receiver, or powered speakers. The red plug is for the right audio channel, and the white or black plug is for the left audio channel.
- Connect 3.5mm Plug: Insert the 3.5mm stereo plug into the audio output jack of your source device (e.g., smartphone, tablet, laptop, MP3 player). Ensure it is fully seated.
- Connect RCA Plugs: Insert the red RCA plug into the right audio input jack (often labeled "R" or "Right") on your amplifier, receiver, or speaker. Insert the white or black RCA plug into the left audio input jack (often labeled "L" or "Left") on your audio equipment.
- Power On Devices: Once all connections are secure, power on your audio source device and your receiving audio equipment.
Note: Ensure that the volume levels on both your source device and receiving audio equipment are set to a low level before playing audio to avoid sudden loud sounds.
5. Operation
After successful setup, operating the Y-adapter cable is straightforward:
- Select Input: On your amplifier or receiver, select the input source that corresponds to the RCA jacks where you connected the Y-adapter cable. This might be labeled "Aux," "Line In," "CD," or similar.
- Play Audio: Start playing audio from your source device (e.g., music, podcast, video).
- Adjust Volume: Gradually increase the volume on your amplifier/receiver and your source device to a comfortable listening level.
The Y-adapter cable facilitates the transfer of stereo audio signals from your 3.5mm output device to your RCA input audio system.
6. Maintenance and Care
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Do not use liquid cleaners or solvents.
- Storage: When not in use, coil the cable loosely. Avoid tight coiling or kinking, which can damage the internal wires. Store in a cool, dry place away from direct sunlight.
- Inspection: Periodically inspect the cable and connectors for any signs of wear, fraying, or damage. If damage is observed, discontinue use.
