When setting up a turntable, one important decision you need to make is whether to connect it to the “Phono” or “Line” input on your audio system. This choice depends on the type of turntable you have and the specific features of your audio setup. In this article, we will explore the differences between the Phono and Line inputs and guide you in determining which input is suitable for your turntable.
Understanding Phono and Line Inputs: Phono and Line inputs serve different purposes and are designed to accommodate different types of audio signals.
- Phono Input: The Phono input is specifically designed for turntables. It incorporates a built-in preamplifier, also known as a phono preamp or phono stage, which is responsible for amplifying and equalizing the low-level signal produced by a turntable’s cartridge. The Phono input compensates for the frequency response and signal level characteristics of vinyl records, which are inherently different from other audio sources.
- Line Input: The Line input, on the other hand, is a standard input found on audio systems and amplifiers. It accepts line-level signals, which are already amplified and equalized, typically coming from sources like CD players, MP3 players, or streaming devices. Line-level signals have a higher output level than the low-level signal produced by a turntable cartridge.
Choosing the Correct Input: To determine whether your turntable should be connected to the Phono or Line input, consider the following factors:
- Built-In Preamplifier: Check if your turntable has a built-in phono preamp. Some modern turntables, especially those in the lower price range, come with a built-in preamp, allowing you to connect the turntable directly to a Line input. In this case, select the Line input on your audio system.
- External Phono Preamp: If your turntable does not have a built-in preamp, or if you prefer to use an external phono preamp for enhanced audio quality, you will need to connect the turntable to the Phono input on your audio system. In this scenario, the external phono preamp performs the amplification and equalization of the turntable’s signal before it reaches the Line input of your audio system.
- Compatibility: Ensure that your audio system has the appropriate inputs for connecting your turntable. If it lacks a dedicated Phono input, you may need to consider alternative solutions, such as using a standalone phono preamp or a turntable with a built-in preamp.
- Adjustments and Settings: If you connect your turntable to the Phono input, make sure to check the settings on your audio system or amplifier. Some systems may have additional options for adjusting the gain, capacitance, or impedance to optimize the performance of the turntable.
Conclusion:
Choosing between the Phono and Line inputs depends on the features of your turntable and the inputs available on your audio system. If your turntable has a built-in preamp or you use an external phono preamp, connect it to the Line input. If your turntable lacks a built-in preamp, you will need to connect it to the dedicated Phono input or use an external phono preamp in conjunction with the Line input. Understanding the differences and requirements of Phono and Line inputs will help you make the appropriate connection, ensuring optimal sound quality and compatibility between your turntable and audio system.
