When it comes to setting up a home audio system or a professional sound setup, understanding the various connections and features on an amplifier is crucial. One often-overlooked but essential feature is the line out on an amplifier. In this article, we will delve into the world of line out, exploring what it is, how it works, and why it’s a vital component of any audio setup.
What is Line Out on an Amplifier?
Line out, also known as line-level output, is a type of audio connection found on amplifiers, receivers, and other audio equipment. It’s a pre-amplified audio signal that’s sent to another device, such as a subwoofer, equalizer, or recording device, for further processing or amplification. The line out signal is typically a low-level signal, usually around 1-2 volts, which is much lower than the high-level signal sent to speakers.
How Does Line Out Work?
The line out on an amplifier works by taking the pre-amplified audio signal from the amplifier’s preamp stage and sending it to an external device. This signal is usually taken from the amplifier’s preamp output, which is before the power amp stage. The preamp stage is responsible for boosting the low-level audio signal from the source device, such as a CD player or turntable, to a level that’s strong enough to drive the power amp stage.
The line out signal is then sent to an external device, such as a subwoofer or equalizer, which can further process or amplify the signal. The external device can then send the processed signal back to the amplifier, which can then send it to the speakers.
Types of Line Out Connections
There are several types of line out connections found on amplifiers, including:
- RCA connectors: These are the most common type of line out connection and are usually found on home audio equipment.
- XLR connectors: These are commonly found on professional audio equipment and are known for their balanced audio signal, which can reduce noise and hum.
