2.1 Component Identification

Figure 2: Preamp Front and Rear Panels with Labeled Connections

This image provides a detailed view of the preamp's front and rear panels, highlighting the 12V DC power input, ground terminal (GND), L/R RCA inputs, 1/4" TRS output, and L/R RCA outputs. The 'ON' power LED indicator is also shown.

• 12V DC Input: Connect the included 12V DC power adapter here.
• GND (Ground) Terminal: Connect your turntable's ground wire here to reduce hum and noise.
• INPUT (L/R RCA): Connect your turntable's RCA output cables to these inputs.
• OUTPUT (L/R RCA): Connect these outputs to your amplifier, receiver, or powered speakers' line-level RCA inputs.
• OUTPUT (1/4" TRS): Alternatively, connect a 1/4" TRS cable from this output to compatible audio equipment.
• ON LED Indicator: Illuminates green when the preamp is powered on.

2.2 Connection Steps

1. Ensure all audio equipment is powered off before making connections.
2. Connect the RCA output cables from your turntable to the INPUT (L/R RCA) ports on the Jancane Phono Turntable Preamp.
3. If your turntable has a ground wire, connect it to the GND terminal on the preamp.
4. Connect the OUTPUT (L/R RCA) ports of the preamp to a line-level input (e.g., "CD," "AUX," or "LINE IN") on your amplifier, receiver, or powered speakers using RCA cables. Alternatively, use the OUTPUT (1/4" TRS) port if your audio equipment supports a 1/4" TRS input.
5. Connect the included 12V DC power adapter to the 12V DC Input on the preamp and then plug the adapter into a power outlet. The 'ON' LED indicator will light up.
6. Once all connections are secure, you can power on your audio equipment and turntable.

Figure 3: Typical Connection Diagram

This diagram illustrates the connection flow: a turntable connects via RCA cables to the preamp's input, and the preamp's output connects to an AV receiver's audio input. This setup allows a turntable to be used with receivers lacking a dedicated phono input.

3. Operation

Once the preamp is correctly connected and powered on, it will automatically convert the phono signal from your turntable to a line-level signal suitable for your audio system.

• Ensure your amplifier/receiver is set to the correct input channel where the preamp is connected (e.g., AUX, CD, Line In).
• Adjust the volume on your amplifier/receiver to your desired listening level. The preamp does not have its own volume control.
• The Jancane Phono Turntable Preamp is designed for low-noise operation, ensuring that your vinyl records deliver sound accurately as read from the turntable's needle, minimizing unwanted interference.
