- Select Switch: Rotary knob to choose between channels 1, 2, 3, or 4.
- Volume Knob: Adjusts the output volume from 0 to 10.
- IN/OUT Port: Bi-directional RCA L/R stereo port.
- OUT/IN Ports (1-4): Four bi-directional RCA L/R stereo ports.
Connection Modes
The switch supports two primary connection configurations:
Mode 1: 4 Inputs to 1 Output
In this mode, you can connect up to four audio source devices (e.g., DVD player, laptop, smartphone, CD player) to the four "OUT/IN" ports (1-4). The single "IN/OUT" port then connects to your audio output device (e.g., active speakers, amplifier). Use the Select Switch to choose which of the four input sources is sent to the output.

Mode 2: 1 Input to 4 Outputs
In this mode, a single audio source device (e.g., DVD player, laptop) is connected to the "IN/OUT" port. The four "OUT/IN" ports (1-4) are then connected to up to four different audio output devices (e.g., active speakers, amplifier, tube amp, headphone amp). Use the Select Switch to choose which of the four output devices receives the audio signal from the single input.

General Connection Tips
- Ensure all devices are powered off before making connections.
- Use high-quality RCA cables for optimal audio performance. The included 1.5m RCA cable can be used for initial setup.
- Connect the red RCA plug to the right audio channel and the white (or black) RCA plug to the left audio channel on all devices.
- The input and output connectors are conveniently located on the same side of the device to simplify cable management.

4. Operation
Once all audio devices are connected, follow these steps to operate your PROZOR RCA Audio Switch:
- Power On Devices: Turn on all connected audio source and output devices.
- Select Channel: Rotate the Select Switch knob to choose the desired input source (in 4-in-1-out mode) or output destination (in 1-in-4-out mode). The selected channel will be indicated by the knob's position (1, 2, 3, or 4).
- Adjust Volume: Use the Volume knob to adjust the audio output level. The volume can be adjusted from 0 (mute) to 10 (maximum). It is recommended to reduce the volume to 0 before switching channels to prevent sudden loud sounds or pops.

5. Troubleshooting
If you encounter issues with your PROZOR RCA Audio Switch, please refer to the following common troubleshooting steps:
- No Sound:
- Ensure all RCA cables are securely connected to both the switch and your audio devices.
- Verify that the correct input/output channel is selected on the PROZOR switch.
- Check the volume level on the PROZOR switch and all connected audio devices (source and output).
- Confirm that the audio source device is playing audio and the output device is functioning correctly.
- Try bypassing the switch to connect devices directly to isolate the problem.
- Static or Noise:
- Ensure all cable connections are firm and not loose.
- Check for any damaged RCA cables and replace them if necessary.
- Verify that the audio source itself is not producing static or noise.
- Ensure the switch is not placed too close to devices that emit strong electromagnetic interference.
- Some users report slight noise when switching channels; this is generally momentary. Reducing volume before switching can mitigate this.
- Distorted Audio:
- Check the volume levels on all devices. Overdriving the input or output can cause distortion.
- Ensure the audio source is providing a clean signal.
- Inspect RCA cables for damage.
- Difficulty Switching Channels:
- Ensure the rotary knob is turned firmly to each detent position.
