All Pro-Ject turntables are balanced signal sources by their nature, but the ability to exploit this beneficial technology has traditionally only been available to more high-end or bespoke analogue systems. Pro-Ject’s True Balanced Connection concept intends to extend these benefits to a broader variety of vinyl enthusiasts than ever before.
The interconnect cable between a record player and a phono stage is prone to pick up noise on the way. That noise and interference can stem from a lot of unavoidable sources, such as household applicances, wi-fi and bluetooth devices, other power cables and audio amplifiers. Unshielded (i.e. RCA) interconnects can amplify the picked-up noise and make it audible through your speakers, interfering with the pure musical signal.
Balanced (typically XLR) cable connections double the wires carrying the musical signal – with one side inverted. In this case noise still gets picked up by both wires, but with one side reversed. When the signals are re-joined at the phono stage, the picked-up noise is cancelled out by the opposing signals. The benefit of this is a louder, cleaner musical signal that has doubled in size with almost no remaining noise.
The benefits of True Balanced Connections therefore include:
When running true balanced connections between the turntable and phono stage, all of these benefits reveal themselves in a more inviting musical performance that's free of noise. Pro-Ject produce a variety of turntables, cables and phono stages that can all be combined to benefit from balanced signal transfer.
Please Note: Balanced Connections are not the same thing as "fully balanced" devices. The benefit of the above is in transporting the musical signal from the turntable to the phono stage in the most efficient and high-quality manner possible. Look out for fully-balanced electrical devices separately.
