Simple Explanation

Outputs that send a preamplified signal (line-level signal) to an external amplifier, typically found on preamplifiers, AV receivers, or pre-processors.

Concise Technical Definition

Pre-outs (or preamp outputs) are the outputs on an audio device that send the unamplified line-level signal from the preamplifier section to an external amplifier. These outputs are commonly found on preamplifiers, AV receivers, or pre-processors, allowing the user to connect the preamp signal to a power amplifier or other audio equipment for further amplification.

Layman-Friendly Analogy

Think of pre-outs like a delivery truck picking up goods from a warehouse (the preamp) and taking them to a larger truck (the power amplifier) for delivery to the final destination (the speakers).

Industry Usage Summary

Pre-outs are commonly used in high-end audio systems, allowing users to separate the preamp and power amp stages for better sound quality and flexibility. AV receivers, preamplifiers, and processors often have these outputs to allow external amplification. This feature is especially useful in custom audio systems where separate amplifiers are used for different channels (e.g., surround-sound systems). Pre-outs are a critical feature in home theater setups where external amplification is needed for optimal sound reproduction.

Engineering Shortcut

Outputs from a preamp that send the unamplified, line-level signal to an external amplifier.

Full Technical Explanation

Pre-outs (preamp outputs) are designed to send the signal from the preamplifier stage of an audio system to an external power amplifier. These outputs carry the unamplified, line-level signal, which is typically what you would use to drive external amplification. Pre-outs are found on devices such as preamplifiers, AV receivers, and pre-processors, allowing users to route the preamplified signal to external amplifiers for further amplification. This feature is important for audiophiles or professional audio setups where higher quality or multi-channel amplification is required.
